mycroft-classic-listener 0.2.2a1

ovos-core listener daemon client (classic Mycroft implementation)

mycroft-classic-listener

The classic mycroft-core listener updated to use OVOS packages.

This does not support instant_listen, multiple hotwords, VAD, listening modes or Fallback STT

fallback hotwords are supported via OPM
