Hi Asif,

It is up to your plugin to implement speech endpointing. The energy-based VAD implementation is used in/for the demo plugins only.

Hi Arsen,

Should we understand methods like mpf_activity_detector_process, mpf_activity_detector_noinput_timeout_set, ... do not work outside the demo plugins?

Yours sincerely,

Hi Julien,

The mpf_activity_detector is used mostly for the demo purposes and shall not be considered for production use.
