Hello Everyone,
I have two question here and I hope help me for answers:
1- If I want to buy Mic array to use it for Speech Recognition, What is the Mic array products now in market?
2- Why most of devices like Amazon Alexa and Google use MEMS Microphone Array ( Digital PDM Mic)?, other hand most of robots use electret Microphone Array not MEMS digital Microphone Array?
Many Thanks,
