Acoustic Echo Cancellation (AEC) timeline?

Is there any predicted timeline on when acoustic echo cancellation (AEC) will be available, either on the Voice’s micro controller directly or even handled by a Raspberry Pi?

This feature was mentioned prominently in the campaign for the Matrix Voice, and is a major reason for my decision to back it, yet I haven’t seen any of the examples demonstrating this functionality.

Was this ever resolved? Does the device now offer AEC?

To my knowledge, no, there are still no examples of working AEC for the Matrix Voice.

I have since moved on to products that support this functionality, as it does not appear that the Voice will get this feature anytime soon.
