picovoice for teensy ?

[StefanL38]

Hi everybody,

some minutea ago I discovered this article about picovoice
https://medium.com/picovoice/its-tim...n-df7c911fe944

This sounds very interesting. They claim that this approach for voice-recognition can even run on microcontrollers.
My first thinking was. "april fooling? " No. It is a very different approach than general voice-recognition.

For a teensy this should be possible too.

@ PaulStoffregen: what do you think?

best regards Stefan

This is certainly possible, although it depends what level of "voice-recognition" you are looking for in terms of complexity and functionality. Full NLP (e.g. Alexa) I am doubtful, but you can likely cover most of the key phrases along with any wakeword detection on device. NXP has several voice solutions running on these microcontrollers on their website, and I see picovoice has a demo running on a RT1050-EVK, a device which appears to be extremely similar to the RT1062 on T4.

@ PaulStoffregen: what do you think?

I think it seems really interesting, but I'm too overloaded with dealing with chip shortages and another PCB revision on Teensy 4.0 & 4.1 to do anything with voice recognition right now.

I'm hopeful the chip crisis will look better by late July, but very difficult to know right now.
