Test Pattern 140-190hz
Due to a dearth of published information regarding the right channel independent eye and mouth control I've been letting Google Gemini take control of an original 1985 Teddy Ruxpin via Bluetooth cassette.
This is one of the best test patterns prior to holding a pretty decent conversation in live mode with spot-on mouth control... But not enough luck keeping the eyes open during moments that they appropriately should be or being able to generate lifelike blinking patterns.
If anyone has prior published specs on any information regarding the audio to DC conversion patterns, pulses, frequencies, or amplitude shifts needed for independent motor control it could help accelerate the process of developing a live speech system for unmodified T-10000s.
