Microphone.py question #43

Closed auvilink closed 5 years ago

auvilink commented 6 years ago

Hi, there,

I am using Respeaker USB 4 Mic Array (you might have the same mic array) for speech recognition.

This mic array has 6 channel audio output, so which channel does this microphone.py speech recognition actually use?

As far as I understand, the first channel (channel 0) is the one processed for asr, any chance we can use that channel?

Thank you.

@auvilink If you just want the first channel, you can use the mono channel firmware. See https://github.com/respeaker/usb_4_mic_array
