Issue or Suggestion Description

Does light sleep work with SR? Or is there a guideline for power saving while SR is running?

feizi commented 1 month ago

The best way is to use low-power VAD. Currently, ESP32-P4 has a built-in low-power VAD on the LP coer. ESP32-S3 need to implement a low-power VAD on the CPU core. The VAD algorithm is simple and can be run at a lower frequency to reduce power consumption.

For ESP32S3, the low power VAD is already implemented? Or it is going to be implemented?

feizi commented 1 month ago

We do not plan to implement low power VAD for ESP32S3. There will be another solution in the future for esp32s3.

ok. hope the new solution will be released soon.

But for now, when SR is in use, can I enable "light sleep" or "modem sleep"?
