Speech recognition library

[fede99]

Goodmorning,

I'm working on a project running on nrf840. I would like to add a speech recognition system able to recognize some words ( more or less 10 words).

There is some Nordic compatible library ?

thank you so much

Hi,

I do not have any experience with this, but I found this "Keyword Spotting for Microcontrollers" library from ARM, which may be of interest.

Not sure about your comment about ADC, but if you are thinking for capturing the voice, I would rather recommend that you have a look at the audio-peripherals like PDM and I2S.

We have voice capture/recognition features in the Smart Remote 3 reference design, but here the voice recognition is not processed on the nRF chip.

Best regards,
Jørgen

thank you so much for your support.

I also found TensorFlow Lite suitable for this purpose. 

do you you know it? do you have any feedback on it ?

thank you
