AMB82-mini to support voice activation

Arduino SDK
1

Dear All,

AMB82-mini is a perfect EVB for Edge-AI applications,

but it misses the voice activation feature :

  1. audio volume-level detection to wakeup

  2. keyword recognition activation

Hope these can be supported soon !

Hi @rkuo2000 ,

Thanks for your suggestion. We are currently evaluating this feature and will provide you an update once it is ready.

Hi @rkuo2000 ,

For the audio volume level detection request, we have added an API to read the mic audio level in Arduino SDK. As per your previous request, we have created an example to activate recording using audio input, please refer to the patch files attached. Meanwhile, we are currently studying on the ways to trigger wakeup using external low power audio detection source.

Thank you.

It works fine, excellent example !
I can wake up the AMB82-mini by a sound or speaking to it now :smiley:

Nice one! It is great to hear that you are able to wake up the AMB82-mini by a sound, is there any example that you would like to share on your GitHub?

Thank you.

Hi @rkuo2000 ,

We have included a new example “SoundDetectorTrigger” in our Arduino SDK. You may refer to the example guide here to try it out. This example demonstrates how the audio presence signal picked up by the SparkFun Sound Detector can light up the green LED on the AMB82-mini.

You may also use this sound detector to wake up the AMB82-mini via AON GPIO. Kindly refer to the “DeepSleepMode” section of the Sound Detector example guide.

Thank you.

Hi Kevin,

Thanks, I confirm the example AudioTriggerRecording.ino works with the mic on AMB82-mini
