Voice Assistant (Skainet) wake word microphone requirements?

Postby mchahn » Mon Apr 26, 2021 4:52 pm

I'm designing a custom low-end esp32 smart speaker. It hope to have a single mic input (ICS-43434 microphone/adc/i2s) and a speaker. I hope to use the Voice Assistant (Skainet) wake word feature. No speech recognition is needed.

Do I need a mic array (beam-forming) to recognize wake words at a decent distance like 3 meters? Or would a simple single mic work.

Are there any other mic requirements?
