AEC with phone calls

Post by tranhau102495 » Tue Feb 12, 2019 4:38 pm

When I make phone calls with my ReSpeaker device with the audio coming out of a speaker connected to the 35mm jack, there is a noticeable echo. How can I go about tuning/improving the AEC? Are there any resources I can follow?

Hello, it is said that the echo of 2-mic is harsher than other kinds of Respeaker, and things will be better on the nearest framework, please try 2018-08-06-raspbian-for-respeaker.zip.

I have seen from the Internet that the software package Speex of Linux can mute echo, I think it might be helpful for you.
