[For Hire] AI Voice Assistant Developer

https://youtu.be/Ey3CqNF4RXc

My latest project is a real-time virtual co-founder called "Made with Chat". I’ve attached a quick demo of the pre-release version that I can share.

I’m currently available to take on my next project, preferably in the same niche, where I can apply the experience I got while working on MWC. I have 12 years of experience as a software engineer and have been working with AI integrations for the past three years.

I offer a free 30-minute consultation. Feel free to reach out by DM or on LinkedIn, and we can set up a meeting to discuss your project.

The voice agent I developed has several distinctive features:

• Minimal latency, including voice control of the UI
• Turn-taking that works better than ChatGPT Voice
• The ability to run and manage multiple background tasks
• File-system based long-term memory

In more detail:

Minimal latency is achieved by using LiveKit Inference, which means that the providers in the voice pipeline (STT-LLM-TTS) share the same location. A fast LLM reads the live transcription and detects the user’s intent faster than the main voice pipeline. This is used for opening documents by voice and controlling other parts of the UI.

In addition to standard VAD, the system uses a semantic turn-taking model that understands when you have finished your thought. It also detects false interruptions, i.e. your coughing into the mic will not interrupt the response.

The system has two layers. The top layer is a voice agent with a minimal system prompt and a fast LLM. It sends instructions to a Deep Agent, which handles heavier and more time-consuming tasks. The Deep Agent has access to a set of skills and can create its own sub-agents.

Contest-Based Freelance Platform

I know this is not a new concept, but I do not think it has ever been widely adopted. Its main limitation is that it works best for tasks with a fixed and clearly defined scope, rather than long-term contracts.

Here is how it works: a business posts a clearly defined task and provides a guaranteed prize pool. Several qualified developers create independent solutions following the same deadline and evaluation criteria. Every error-free solution that meets the requirements gets paid, while the highest-scoring developers receive larger rewards.

So, unlike traditional freelance platforms, there are no job interviews, proposals, or resumes. Developers are selected based on working, tested solutions rather than promises. This gives beginners the same chance of getting paid for good work.

Thoughts?😄

Technical Cofounder available

LinkedIn:
https://www.linkedin.com/in/theic/

I’ve been in tech for the past decade, mostly working in the Node.js ecosystem. Over the last two years, I’ve been leading a real-time voice application that manages a multi-agent system, similar to a virtual co-founder.

I’d be excited to join a voice app, agentic, or other AI-related project.

You can find some of the projects I’ve worked on with a team, as well as two personal side businesses I recently launched, here:

At the moment, I can’t work fully for equity or revenue sharing, so I would need at least some financial compensation from the beginning.

Happy to chat, cheers.

Your dream freelance platform, thoughts?

TL;DR:
How do you guys find work if you have to start from zero? What would a platform that respects both sides look like from your perspective? Maybe my broke ass can somehow help the community make that dream come true. 😬

---
I have occasionally used Upwork since 2015 and other platforms since 2012. Even though it saved me a few times, I have seen people’s frustration grow year after year.

Now I am in a situation where I urgently need a job, even a short term. I cannot use my Upwork profile because I lost access to my bank account and do not have my papers ready. So far, I have managed by using crypto and my wife’s bank account. I am afraid I will get blocked for breaking the ToS, or that I will not get paid and will just lose time.

I am trying to remember my experiences, and I feel like freelance platforms in general do not solve the main problems, except for being a place where the two sides meet.

- You still have to interview people, and even that does not give you enough confidence in the applicant.
- You can still be scammed, and I was. Escrow will not help you much.

It is a rather complex question, I guess, like electing a new president (I have thoughts on that too).

Now I am browsing forums like its 2010 and trying to prove that I can do something I know I have done dozens of times. I hope I’ll be able to climb out of this financial hole I got myself into, but I also want to help other desperate, love-working people along the way.

Built a live two-way translator after moving abroad with none of the local language (launching on PH today)

5 months ago we left Ukraine because of the war. My wife, two dogs and me, no plan and no time to prepare. We ended up in a small village in Portugal where almost nobody speaks English and the average age is 60+, and I spoke exactly zero Portuguese.

I tried a few apps, expecting Google Translate and ChatGPT voice mode to cover my needs. The first one is too literal and often creates awkward situations by changing the meaning completely. ChatGPT is better, but it's slow and turn-based, which doesn't work well with the fast-speaking locals. I needed something that just let me talk to a real person, right now, understand the context of the conversation and reply fast.

So I built a quick prototype in a week, using the new real-time translation model from OpenAI and another one from Microsoft. It was great at first, but then I realized those audio models are too sensitive to audio quality. One wrong move and it generates gibberish, just like Google Translate before.

Then my sister (I'd worked with her on another project before) asked why I wouldn't just build a custom pipeline. And I thought, really, why not? 😁 That's when I took the best STT and TTS models I know and connected them with a multi-language LLM. Turns out transcription quality is the key, and I started using the app every day.

What it actually does:

  1. Live two-way voice translation. Both people just talk normally and it speaks the translation out loud, back and forth.
  2. Camera translation for signs, labels, menus and documents. It's not like Google Lens, it uses Nano Banana to generate a new image with everything translated on it.
  3. Quick text translations that come out the way a local would actually say it, not word for word.
  4. Live dubbing: just connect another tab in your browser and it will dub any audio/video input with a live voice.

There's also a Practice mode with an AI tutor, which is like a simulation of a real conversation so you can rehearse the awkward one before you have it (ordering coffee; the call with the landlord; the appointment), and it quietly brings back the words you got wrong last time. But the real help you get the minute you install it is the translation.

I'm a developer, around 12 years, the last 3 fully on real-time voice and multi-agent systems. The hard part here is the live pipeline (speech in, translation, speech out) feeling fast enough to hold an actual conversation, so that's where most of the work went.

It's free to start, no card. We're launching on Product Hunt today, link in the comments.

If you've moved somewhere without the language, I'd genuinely like to hear what your worst communication moment was. And any feedback on the app is welcome, good or brutal. Cheers.

Looking for people to try a live voice translation app

This is a small web app that does one thing: it helps two people have a live conversation when they don’t speak the same language. You can also use it to translate a show or a video live, here is an example.

https://youtu.be/TEo32EpAneM

https://youtube.com/shorts/jOPyoNQs6aA?feature=share

It translates the person you’re talking to into your ear (or the speakers), and helps translate your reply back to them. It also shows the transcript on screen, so it can be useful for learning from real conversations too.

Here is the link for testing, no need for an account, you get 15 minutes for free. You only have to choose your language and the language of the other person you're talking to.

https://vocavela.live/

I’m not asking for a long beta-testing commitment, I’m looking for people to try it in a real situation and give an honest opinion. I can also increase the free time limit upon request.

I recently moved to Portugal with my wife and built it for my own daily use: shops, cafes, talking to neighbours etc. Before that I tried Google Translate, ChatGPT voice mode and other apps, but most of them are not fast / good enough.

The first version was fully real-time. I used two "gpt-realtime-translate" sessions at once, one translating the person I was talking to, and one translating my speech back to them. It sounded like the perfect approach, but that new model is too sensitive about the audio quality and most of the time just can't get the context right. Even with native speakers, the translation could lose the meaning.

So the current version is more practical: it uses a combination of models. The other person’s speech is translated live, and when you want to reply, you hold a button, speak, and it generates a better translation with an LLM and narrates it with TTS. Less magical, but much more useful in real-life scenarios.

Useful feedback would be:

- Is it fast enough for a real conversation? (both live translation + replies)

- Does the spoken translation feel helpful or annoying?

- Where does it feel awkward or break?
