Digital PDM & electret Microphones

Postby abdullahkamel » Wed Mar 22, 2017 9:30 pm

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,
