I genuinely didn’t even know this existed.

I was looking around recently and randomly stumbled upon Narrate, a community-developed Obsidian plugin that integrates with OpenVox for text-to-speech.

So naturally, I had to try it.

The demo shows OpenVox voices being used directly inside Obsidian to listen to notes without having to copy/paste everything into another app.

Pretty cool seeing people build integrations around OpenVox independently, this is exactly the kind of stuff I hoped would eventually happen, but I definitely wasn't expecting to discover one by accident. 😄

I recorded a quick demo so you can see it in action.

I also wrote a little more about the plugin and how to use it here:

https://openvoxai.com/blog/obsidian-text-to-speech-narrate-openvox

Huge credit to https://github.com/jang-hs who built this.

If anyone knows of other OpenVox integrations/plugins people have built that I somehow don't know about, please send them my way. 👀

The biggest change is under the hood: we’ve introduced an all-new native C++ TTS audio engine. By removing a lot of the Python overhead, we're seeing roughly 2x–5x faster generation depending on the model and hardware, along with lower memory usage and faster loading.

We’ve also spent quite a bit of time improving support for people who don’t have huge amounts of VRAM.

⚡ Native C++ TTS Engine

• Around 2x–5x faster generation
• Lower memory/VRAM overhead
• Around 30% faster app startup
• Native acceleration for supported models

🔴 AMD GPU Support

AMD users can now use native ROCm/HIP acceleration.

This has been one of the most requested Windows features for a while, so I'm particularly interested in hearing how it performs across different Radeon cards.

The video attached to this post shows it running on an RX 9060 XT.

🧠 Quantized Models

We've added Large and Medium quantized versions of larger TTS models including:

• Qwen3 TTS
• Chatterbox
• OmniVoice
• Vibevoice

This should make these models much more practical on GPUs with limited VRAM.

🎬 New AI Dubbing Studio

This is the other big part of the update.

You can now:

• Drop in a video or audio file
• Automatically transcribe it
• Detect up to 4 different speakers
• Translate the dialogue
• Rename/reassign speakers
• Assign a different AI voice to each speaker
• Generate synchronized dubbed speech
• Export the resulting dub

There’s also HTDemucs integration, so OpenVox can separate vocals from the original background audio and preserve things like music while replacing the dialogue.

The video demonstrates the full workflow by taking a video, identifying its speakers, separating the background track, translating the dialogue to Spanish, assigning voices and generating the final dub.

📝 Multi-Speaker Transcription

Drop & Transcribe can now perform speaker diarization as well.

You can rename speakers directly, reassign incorrectly detected segments and export a speaker-labelled, time-coded SRT.

We also fixed the Sortformer speaker diarization issue introduced in v2.3.0.

🔊 Select & Read Improvements

Select & Read has also received some attention in this release:

• Better reliability
• Smoother reading experience
• New draggable Select & Read overlay

So you can move the controls somewhere convenient instead of having them stuck in one position.

🔌 API

Pause tags are now supported through the API as well.

And there are a bunch of smaller UI optimizations and bug fixes throughout the app.

Would especially love feedback from AMD GPU users and anyone trying the new Dubbing Studio / multi-speaker transcription workflows.

If you run into something weird, let me know your GPU, VRAM and the model you were using. It helps a lot when tracking down hardware-specific issues.

We put together a simple long-term cost comparison between OpenVox Reader Pro, ElevenReader Ultra, and Speechify Premium.

At current pricing:

• OpenVox Reader Pro: $14.99 one-time
• ElevenReader Ultra: $99/year or $11/month
• Speechify Premium: $29/month

Over 3 years, that works out to:

• OpenVox Reader Pro: $14.99
• ElevenReader Ultra annual: $297
• ElevenReader Ultra monthly: $396
• Speechify Premium: $1,044

One of our main goals with OpenVox Reader has been to keep the pricing simple: no subscription, no recurring fee, and a free tier with daily usage for people who don’t need Pro.

Obviously this is just a pricing comparison, not a full feature-by-feature comparison, but the long-term difference is pretty significant.

Curious what you all think: for reader/TTS apps, do you generally prefer a one-time purchase with good quality or are subscriptions fine if the app provides extra features or slightly better cloud tts quality?

Hey everyone,

After a lot of testing, OpenVox Reader is now available on Android through Google Play Open Testing. 🎉

This is the first public Android release, and you can already try the full OpenVox Reader experience.

During Early Access, you can test all features, including:

• 📚 Import and read PDFs, EPUBs and other documents
• 🔊 Natural on-device Text-to-Speech
• 🎙️ Multiple local AI voice models
• 🗣️ Create and use custom voices

A small note about Pro

Since the Android app is currently in Open Testing, Google Play purchases are not enabled yet.

So you can try all the features during Early Access, but you won't be able to purchase OpenVox Reader Pro until the app moves to the production release.

Once the production version goes live, Pro purchasing will become available normally.

For now, I’d really love Android users to put the app through its paces, especially with:

• Large PDFs and EPUBs
• Long reading sessions
• Different Android phones/tablets
• Background playback
• Different languages and voices
• Custom voice creation

If you run into bugs, weird device-specific behaviour, or have ideas for the Android version, please let me know.

This is exactly why I wanted to do an open testing period before the full release.

Would love to hear how it performs on your device!

Hey everyone,

I’ve just released OpenVox for iPad v1.6, and this is easily one of the biggest updates to the iPad version so far.

The main goal with this release was to bring much more of the complete audio/video workflow directly onto the iPad, while keeping the core AI processing local and private.

🎬 AI Video & Audio Dubbing

You can now dub complete video and audio files directly on your iPad using a new 5-step workflow:

Media Import → Script → Translation → Voice Assignment → Dubbed Output

Import your media, transcribe it, translate the dialogue if needed, assign different voices to speakers, and generate the final dubbed output without needing a desktop.

🗣️ On-Device Speaker Diarization

OpenVox can now automatically detect who is speaking and when using the local Sortformer MLX diarization model.

You can rename detected speakers and assign a different voice to each speaker before generating the dubbed audio.

📝 Local AI Transcription Studio

Speech-to-text can now run completely locally on the iPad with multiple transcription models, including:

• Whisper Large v3 Turbo
• Parakeet v3
• Nemotron 3.5 Streaming

No audio needs to be uploaded to a transcription service.

🌍 Dual Translation Engines

For dubbing and translation you can choose between:

Apple Translation for completely on-device translation

or

External AI Chat, including support for custom translation prompts when you want more control over tone and context.

✅ Validate & Regenerate Only What Went Wrong

This is probably one of my favorite additions.

Instead of simply giving the generated audio an accuracy score, OpenVox can align the timestamped speech against your original script and highlight sections that may be incorrect.

You can then:

Listen to the questionable section, review or edit the expected text, select only the parts that need fixing, and regenerate just those ranges.

You can listen to the regenerated result before accepting it, and the original audio remains untouched until you confirm the replacement.

No need to regenerate an entire long project because of one bad sentence.

🧙 New "Help Me Select" Model Wizard

With more voice and transcription models being added, choosing the right one was starting to get confusing.

The new interactive Help Me Select wizard asks what matters most to you, such as speed, quality, voice cloning, or transcription requirements, and recommends an appropriate model.

🔒 Local AI & Privacy

The thing I’m continuing to focus on with OpenVox is making these workflows possible without requiring your private audio, videos, transcripts, or voices to constantly leave your device.

Speech recognition, speaker diarization, and voice synthesis can all run completely offline on the iPad.

There are also a number of UI improvements, performance improvements, and bug fixes throughout v1.6.

Would really love feedback from anyone using the iPad version, particularly on AI Dubbing, diarization, transcription accuracy, and the new Validate Output workflow.

Hi r/iOSApps,

I recently released another major update to OpenVox Reader, an iPhone and iPad app that reads EPUB books, PDFs, documents, web articles, scanned pages and pasted text aloud using natural-sounding voices.

The biggest addition since my last post is the ability to create your own custom English voice from a short voice sample using Pocket TTS.

You can then use that voice to read your books, PDFs, articles and other documents directly on your iPhone or iPad.

The recent updates also add Focus Mode, Saved Sentences, Search in Document, better navigation for large EPUBs and several playback improvements.

Create Your Own Voice

OpenVox Reader now lets you create a custom English voice from a short voice sample using Pocket TTS.

Once created, your custom voice is added to the Voice Library and can be reused for different books and documents.

You can use it for:

• EPUB books
• PDFs
• Documents
• Web articles
• Scanned pages
• Pasted or typed text

The voice creation and speech generation happen locally on your device.

Once the required model is downloaded, your voice sample and documents do not need to be uploaded to a cloud text-to-speech service.

You can still choose from 200+ included voices across 30+ languages as well.

What else is new

The latest updates include several improvements to the actual reading experience.

Focus Mode

There is now a new Focus Mode for distraction-free reading and listening.

The reader interface has also been cleaned up with:

• A dedicated Chapters button
• Text-size controls moved into the reader menu
• Improved button responsiveness
• Larger and more reliable touch targets
• A less cluttered reading interface

Saved Sentences

You can now bookmark individual sentences while reading or listening.

Saved sentences can be:

• Revisited anytime
• Filtered
• Used to instantly jump back to the original passage
• Removed when you no longer need them

This can be useful for books, research papers, study material, quotes or anything you want to return to later.

Search Inside Documents

OpenVox Reader now includes Search in Document with:

• Matching text previews
• Direct navigation to each result
• Improved EPUB chapter positioning

I also reworked how EPUB bookmarks and search positions are stored so they remain accurate without unnecessarily increasing memory usage.

Better support for large books

Recent updates also include:

• Fixes for importing large and lengthy books
• A draggable chapter scroller for faster navigation through large EPUBs
• Tile and List layouts for both the Document Library and Voice Library
• Improved reading cursor accuracy and synchronization

There is also an option to skip PDF headers, footers and page numbers, which makes longer PDFs much cleaner to listen to.

Why I built OpenVox Reader

After building OpenVox for Mac, iPad and Windows, I started looking for a reader app that I could personally use on my iPhone.

I wanted natural voices, a clean interface, offline processing and a straightforward lifetime purchase instead of another recurring subscription.

Most apps I tried either depended heavily on cloud processing, had expensive subscriptions, offered limited voices or felt unnecessarily complicated.

So I decided to build the reader I was looking for.

Being able to create and use your own voice locally was one of the features I particularly wanted to bring to the mobile version.

What it can do

• Read EPUB books, PDFs and documents aloud
• Save and listen to web articles
• Scan and read printed pages using the camera
• Read pasted text
• Import documents and links
• Create your own custom English voice from a short voice sample
• Choose from 200+ voices across 30+ languages
• Generate speech locally and listen without an internet connection
• Search inside documents
• Save individual sentences and jump back to them later
• Navigate large EPUBs with a draggable chapter scroller
• Adjust playback from 0.5x to 2.5x
• Skip PDF headers, footers and page numbers
• Continue listening with the screen turned off
• Control playback from the Lock Screen and Control Center
• View animated playback feedback in Dynamic Island
• Sync your library between iPhone and iPad using iCloud
• Track listening time and reading streaks

Once the required voice models are downloaded, speech is generated directly on your device. Your documents do not need to be uploaded to a cloud speech service.

Pricing

OpenVox Reader is free to download and try.

It offers 15 minutes of reading daily for free for lifetime.

For users who want unlimited usage, there is an optional Lifetime Pro purchase for $14.99.

There is no recurring subscription required.

One purchase works across both iPhone and iPad (even on Mac, although not officially supported) when using the same Apple ID.

I would really appreciate feedback about the voices, document importing, background playback and longer listening sessions.

A nice surprise today — OpenVox AI and OpenVox Reader were featured by iPhoneBlog.de in their latest video/post.

It’s always a little surreal seeing something I’ve been building show up on sites I’ve followed in the Apple community.

OpenVox was mentioned alongside apps like ElevenReader and Matter, which is pretty cool company to be in.

For anyone interested, here’s the feature:

https://www.iphoneblog.de/2026/09/04/tipp-openvox-ai/

Thanks to everyone here who has tried OpenVox, reported bugs, suggested features, or simply followed the development. A lot of what the app has become has come directly from that feedback.

Back to building. 🙂

Hey everyone,

OpenVox v2.6.0 is here, and this update is heavily focused on expanding the quality and usability of local AI voice generation.

We’re introducing two brand-new high-fidelity TTS models, a completely redesigned Model Selector with a guided Help Me Choose wizard, model pinning, a new Transcription API, and several improvements to the local generation engine.

🎙️ New High-Fidelity Models

MOSS TTS 1.5

OpenVox now supports MOSS TTS 1.5, bringing:

• Studio-grade 48 kHz local voice synthesis
• Voice cloning
• Support for 31 languages
• High-quality speech generation completely on-device

Qwen3 TTS 1.7B

We’ve also added the larger Qwen3 TTS 1.7B model for users who prioritize quality and expressiveness.

It provides:

• Higher-fidelity speech
• Deeper expressiveness
• Improved voice-cloning cadence
• Support for 10 languages
• A significantly larger 1.7B parameter architecture

New-generation models are now also marked with a NEW indicator throughout OpenVox, making them easier to discover.

🧭 New “Help Me Choose” Model Wizard

As OpenVox continues adding more local TTS models, choosing the right one can get increasingly confusing.

So we built Help Me Choose.

Instead of comparing every model manually, the new guided 5-step wizard asks about things like:

• Your language
• Whether you need voice cloning
• Emotion and expressiveness requirements
• Quality preferences
• Performance preferences

OpenVox then recommends the model that best matches what you’re trying to do.

📌 Pin Your Favorite Models

If you already know which models you prefer, you can now pin them to the top of the Model Selector.

This makes frequently used models immediately accessible without searching through the complete model list every time.

🎛️ Redesigned Model Selector

The Model Selector itself has also been completely redesigned.

It now uses a more compact, scrollable dropdown layout designed to comfortably handle OpenVox’s growing collection of local speech models.

🔌 New Transcription API

OpenVox’s Local API now includes a Transcription API.

You can use it to transcribe audio or video files locally, making it easier to integrate OpenVox’s speech-recognition capabilities into your own apps, scripts, automations, and workflows.

⏸️ Pause Tags in the Local API

The OpenAI-compatible Local API server now supports OpenVox pause tags:

[pause: Xs]

This means applications using the API can add precise pauses directly inside their input text, just like when generating speech through the OpenVox interface.

⚡ Engine & Memory Improvements

We’ve also made several lower-level improvements to the generation engine.

• Improved autorelease pool management on the MLX background worker thread
• Reduced memory pressure during long-form generation

There are also several UI improvements.

As always, everything is focused on making powerful speech generation available locally on your Mac without requiring your content to be sent to a cloud TTS service.

If you try MOSS TTS 1.5 or Qwen3 TTS 1.7B, I’d especially love to hear how they compare with the models you were using previously.

Thanks for all the feedback and feature requests that continue to shape OpenVox. ❤️

Hey everyone,

OpenVox Reader v1.5.0 is now available!

This update focuses heavily on making the reading experience smoother, especially for large ebooks and lengthy documents, while also improving navigation, playback, and library organization.

📚 Better support for large books

We’ve fixed several issues that could occur when importing large or lengthy books (with 2000+ Chapters), making imports more reliable and improving the overall experience with bigger documents.

🗂️ Tile & List layouts

You can now choose between Tile and List layouts in both:

• Document Library
• Voice Library

So you can organize and browse your content whichever way works best for you.

📖 Faster chapter navigation

Large ebooks are now much easier to navigate with the new draggable chapter scroller.

Instead of scrolling through a long chapter list, you can quickly drag through the book and jump to the section you need.

🎯 More accurate reading cursor

We’ve improved reading cursor accuracy and synchronization, so the highlighted text follows the narration more reliably as OpenVox Reader reads through your content.

🔊 Smoother Pocket TTS playback

Pocket TTS now has improved audio buffering, resulting in smoother and more continuous narration with fewer interruptions between generated audio segments.

⚡ And more

v1.5.0 also includes additional:

• Performance improvements
• Reliability enhancements
• Bug fixes

As always, thanks to everyone sharing feedback, reporting issues, and suggesting improvements. A lot of what goes into these updates comes directly from how you’re using OpenVox Reader.

If you run into any issues with v1.5.0 or have something you’d like to see in the next update, let me know!

Hey everyone,

OpenVox Windows 2.0.0 is now available.

The main focus of 2.0.0 is making locally generated speech more accurate, easier to review, and faster to fix, while also improving Select & Read, multilingual generation, Voice Clone, and voice creation workflows.

And if you missed v1.9.1, that update also introduced two major new workflows: AI Transcription and AI Dubbing.

🔍 Validate Output

This is probably the feature I’m most excited about in 2.0.0.

After generating speech, OpenVox can now:

• Locally transcribe the generated audio
• Compare the transcription against your original script
• Highlight sections that may have been pronounced incorrectly
• Show timestamps and text-match scores
• Let you listen to individual flagged sections
• Select exactly which sections you want to fix
• Regenerate only those sections
• Review the regenerated audio before applying it

You don’t need to regenerate an entire audiobook or long speech because of a few problematic sentences.

Validation matching has also been improved across supported languages, with selectable transcription language/model controls and a Select All option for flagged sections.

Everything can remain local on your Mac.

🎧 Select & Read now has a Queue

Select & Read can now handle multiple selections.

Highlight some text, trigger the shortcut, move to another app, select something else, and trigger it again.

OpenVox adds each selection to a queue and automatically reads them in order.

The entire queue is visible from the desktop notch player, making Select & Read much more useful when working across documents, browsers, emails, PDFs, or other apps.

🗣️ Batch Voice Design

Voice Design can now generate multiple voice candidates in a single run.

You can:

• Generate several variations
• Preview each candidate
• Compare the results
• Save only the voices you actually like

This makes experimenting with designed voices much faster.

⏸️ Configurable Sentence Pauses

There’s now optional Sentence Pauses preprocessing for:

• AI Speech
• Batch generation
• Audiobooks

You can configure additional pauses between sentences from 0.1 to 3 seconds.

Useful for narration where the model’s natural sentence spacing feels too fast.

🌏 Better Japanese and CJK Generation

We’ve added safer multilingual text chunking, particularly for Japanese and other CJK languages.

This improves long-form generation and also fixes a Supertonic issue that could cause crashes when generating longer CJK text.

🎙️ Voice Clone from Video

Voice Clone now accepts:

• MP4
• MOV

OpenVox automatically extracts the audio and uses it as the voice reference, so there’s no need to manually convert a video into an audio file first.

OpenVox 1.9.1

For anyone who missed the previous update, 1.9.1 was also a pretty substantial release.

🎙️ AI Transcription

OpenVox can now locally transcribe:

• Audio files
• Video files
• Direct microphone recordings

using downloadable Whisper and Parakeet speech-recognition models.

Transcripts include timestamps and can be edited directly before exporting them as SRT subtitles.

Subtitle segmentation was also improved to generate cleaner, more usable SRT files.

🌍 AI Dubbing

1.9.1 also introduced a complete AI Dubbing workflow.

You can:

• Import or generate timed transcripts
• Translate scripts using local or external AI
• Choose voices for the dubbed output
• Generate dialogue based on subtitle timing
• Export dubbed audio
• Export the original video with the new audio track

You can also directly import existing SRT or translated SRT files into a dubbing project.

🎬 More Video Workflows

Voice Changer now accepts video files directly and can export the original video with the converted voice track.

AI Speech and Conversations also received Generate SRT actions, making it easier to turn generated speech into subtitle files.

📂 Drag & Drop and Workflow Improvements

We also added:

• Drag-and-drop importing across supported pages
• PDF and TXT importing for AI Speech and Conversations
• Better feedback when importing large files
• Sequential filenames for batch exports
• Persistent text drafts when switching pages
• Quick pause controls
• More reliable model download resume support
• Automatic release of transcription models from RAM/VRAM when leaving transcription workflows
• A notification when OpenVox starts minimized to the system tray

Plus a number of UI improvements, performance optimizations, and bug fixes throughout the app.

With 1.9.1 and now 2.0.0, OpenVox has expanded quite a bit beyond straightforward text-to-speech.

You can now locally handle speech generation, audiobooks, voice cloning, voice design, transcription, subtitles, dubbing, voice changing, Select & Read, and output validation from one app.

As always, a lot of these additions have come directly from feedback and feature requests from users.

If you try 2.0.0, I’d especially like to hear how Validate Output performs with your own scripts, models, and languages.

Thanks everyone for continuing to test OpenVox and send feedback.

Download:
https://openvoxai.com/

Hey everyone,

OpenVox for Mac v2.5.0 is now available.

The biggest addition in this update is something I’ve wanted to build for longer generations: local output validation.

When generating audiobooks, narrations, or large batches, even a good TTS model can occasionally skip a word, mispronounce something, repeat text, or generate something different from the original script.

Until now, finding those mistakes meant manually listening through the entire output.

With Validate Output, OpenVox can now check the generated speech for you.

🔍 Validate Output

After generating speech, OpenVox can locally transcribe the generated audio and compare it against your original text.

It then highlights sections that may need your attention.

You can:

• See potentially incorrect sections with timestamps and text-match scores
• Compare the original text with what OpenVox detected in the generated audio
• Listen directly to the flagged section
• Edit the expected pronunciation or text when needed
• Select only the problematic sections you want to regenerate
• Preview the regenerated audio before making any changes
• Use Confirm & Update to replace only those sections in the final output

The matching system is also designed to avoid unnecessary warnings. It intelligently ignores harmless differences involving punctuation, spacing, apostrophes, and joined words.

Everything happens locally on your Mac. Currently this feature is in Beta and is rolled out on AI Speech page only, it will be rolled out for other pages in next update.

🇯🇵 Better Japanese & CJK Generation

This update also includes several improvements for Japanese and other CJK languages.

Text chunking is now safer for languages where sentence and word boundaries behave differently from English, helping prevent problematic splits during longer generations.

I also fixed a Supertonic crash affecting CJK-language generation.

🎙️ Voice Clone Improvements

Voice Clone can now accept:

• MP4
• MOV

OpenVox automatically extracts the audio from the video, so you no longer need to convert the file separately before using it as a voice reference.

🎛️ More Precise Speed Controls

Speed knobs now support 0.01x adjustments.

This makes it much easier to fine-tune pacing when you need something between values like 0.95x, 0.96x, 0.97x, etc.

⚡ Memory Improvements

I’ve also improved memory handling when switching between speech-generation and transcription models.

This is particularly useful now that workflows like Validate Output can involve both TTS and transcription models during the same session.

OpenVox 2.5.0 includes:

• Local transcription-based Validate Output
• Timestamped validation results with text-match scores
• Selective regeneration of incorrect sections
• Preview before replacing regenerated audio
• Smarter text matching
• Improved Japanese and CJK text chunking
• Fixed Supertonic crashes with CJK languages
• MP4 and MOV support in Voice Clone
• Precise 0.01x speed adjustments
• Improved model memory management

As always, OpenVox keeps the speech generation, transcription, validation, and processing on your Mac.

If you try the new Validate Output workflow, I’d especially like to hear how well it catches issues in your longer audiobook and batch generations.

http://openvoxai.com/

We’ve released two major OpenVox updates back-to-back, and together they add some of the biggest workflow improvements we’ve made so far.

🎙️ OpenVox v2.4.0: AI Transcription + AI Dubbing

OpenVox can now handle complete local transcription and multilingual dubbing workflows directly on your Mac.

AI Transcription

• Transcribe audio files, videos, or direct microphone recordings.
• Choose from multiple downloadable local speech-recognition models.
• Track progress with elapsed time and estimated completion time.
• Access previous transcriptions through the new Transcription History.

🌍 AI Dubbing

• Create dubbed audio and videos using precisely timed scripts.
• Translate scripts using on-device or external AI models.
• Choose your preferred OpenVox voice for the dubbed output.
• Import SRT subtitles directly or use an already translated SRT file.
• Export the finished project as audio or video.

✨ Other v2.4.0 improvements

• Voice Clone can now transcribe reference audio using Apple Speech or downloaded transcription models.
• Voice Changer now accepts video input and can export the video with the converted voice track.
• Added sequential filenames for batch exports.
• Text now remains available when switching between pages.
• Added quick pause controls.
• Improved reliability, performance, media compatibility, and UI throughout the app.

🚀 OpenVox v2.4.1: Better Dubbing, Batch Mode & Long-Form Exports

v2.4.1 builds on the new features with a big focus on workflow polish and reliability, especially for large projects.

AI Dubbing improvements

• AI Dubbing now supports Cloned Voices and Designed Voices directly in the Voice & Output step.
• Improved dubbing timing for more natural results.
• Short lines remain at a natural speed, with silence filling unused time.
• Longer lines can use the available gap before the next active subtitle.
• Speech is accelerated only when the dialogue still cannot fit inside the complete available window.

Batch generation improvements

• Added a Cancel button to the Conversations generation progress panel.
• Batch Mode now uses one overall progress bar across all paragraphs.
• A single completion card is shown when the full batch finishes.
• Added Export All directly to the Batch Mode completion card.
• Cancelling now stops the entire batch.
• Added Export Batch to CSV for easier result management and record keeping.

Long-form export improvements

• Significantly reduced memory usage during the audio merge process.
• Fixed output generation issues affecting 2+ hour audio outputs.
• Export progress is now much more useful for very long generations.
• The final 90% → 100% portion now updates incrementally while OpenVox is Generating the output file... instead of appearing stuck during the merge stage.
• Added a new Export Progress banner.
• Redesigned the export Success Card with quick Open and Locate actions.

Select & Read fixes

• Fixed an issue where the Select & Read player could fail to appear correctly on devices with a notch.
• Improved Select & Read percentage/progress accuracy for several voice models.

Plus additional reliability, performance, and workflow improvements throughout OpenVox.

A huge thank you to everyone who has been testing OpenVox, reporting issues, suggesting improvements, and sharing what you’re building with it. ❤️

If you’ve tried the new AI Transcription or AI Dubbing workflows, I’d especially love to hear how you’re using them and what you’d like us to improve next.

Pocket TTS now supports custom English voices, making it much easier to create and use your own voices directly inside OpenVox Reader.

🔖 Saved Sentences

You can now bookmark individual sentences while reading or listening.

Saved sentences can be:

• Revisited anytime
• Filtered
• Used to instantly jump back to the original passage
• Removed when you no longer need them

This should be especially useful for books, research papers, study material, and anything you want to come back to later.

🔎 Search Inside Documents

OpenVox Reader now includes Search in Document with:

• Matching text previews
• Direct navigation to each result
• Improved EPUB chapter positioning

We also reworked how EPUB bookmarks and search positions are stored so they stay accurate without unnecessarily increasing memory usage.

⏩ Better Playback Controls

Playback speed is now adjustable from 0.5x to 2.5x in 0.1x increments.

We've also added quick presets for:

0.5x · 1.0x · 1.5x · 2.0x · 2.5x

Faster playback has also been improved with better pitch preservation, buffering, voice previews, and more accurate elapsed/remaining time calculations.

A few smaller improvements

• Opening another document automatically pauses whatever is currently playing.
• Reading Stats now count listening time only while audio is actually playing.
• Additional reliability and general reader experience improvements throughout the app.

We're continuing to improve OpenVox Reader based heavily on how people are actually using it, so please keep the feedback and feature requests coming.

If you've tried the update, I'd especially love to hear how you're using Saved Sentences and Document Search.

Hey everyone,

I’ve just launched the official OpenVox Discord server.

As the OpenVox community grows, I wanted to create a more direct and organized place where users can get help, discuss local AI voice models, share feedback, and connect with other creators.

Inside the server, you can:

• Get help with OpenVox and OpenVox Reader
• Report bugs and browse known issues
• Suggest and discuss new features
• Follow release announcements and beta updates
• Share audiobooks, voiceovers, videos, apps, and other projects
• Discuss local TTS models, voice cloning, APIs, MCP, and automation workflows
• Connect directly with me and other OpenVox users

I’ll personally be active there, and feedback from the community will continue to influence upcoming features and improvements.

Join the official OpenVox Discord:

The server is still new, so early members will also have a chance to help shape how the community develops. See you there!

Hi r/iOSApps,

I recently released a major update to OpenVox Reader, an iPhone and iPad app that reads EPUB books, PDFs, documents, web articles, scanned pages and pasted text aloud using natural-sounding voices.

To celebrate the update, the Lifetime Pro purchase is 40% off for the next 24 hours:

$8.99 lifetime — normally $14.99

No subscription or promo code is required. The discounted price is available directly through the App Store.

Why I built OpenVox Reader

After building OpenVox for Mac, Windows and iPad, I started looking for a reader app that I could personally use on my iPhone.

I wanted natural voices, a clean interface, offline processing and a straightforward lifetime purchase instead of another recurring subscription.

Most apps I tried either depended heavily on cloud processing, had expensive subscriptions, offered limited voices or felt unnecessarily complicated.

So I decided to build the reader I was looking for.

What it can do

• Read EPUB books, PDFs and documents aloud
• Save and listen to web articles
• Scan and read printed pages using the camera
• Read pasted text
• Import documents and links
• Choose from 200+ voices across 30+ languages
• Generate speech locally and listen without an internet connection
• Continue listening with the screen turned off
• Control playback from the Lock Screen and Control Center
• View animated playback feedback in Dynamic Island
• Sync your library between iPhone and iPad using iCloud
• Track listening time and reading streaks

Once the required voice models are downloaded, speech is generated directly on your device. Your documents do not need to be uploaded to a cloud speech service.

Pricing

OpenVox Reader is free to download and try. It offers 15 minutes of reading daily for free for lifetime.

For the next 24 hours, the optional Lifetime Pro upgrade is:

$8.99 lifetime — normally $14.99

One purchase works across both iPhone and iPad when using the same Apple ID.
