The scheduled announcements and TTS announcements of VoiceUseCases, as
an official plugin that speaks through send_dmrd. Same configuration
(VOICE.ANNOUNCEMENTS / TTS_ANNOUNCEMENTS in adn-voice.yaml, followed
every 15 s) and the same behaviour: interval or hourly, one playback
per TG at a time 1.5 s apart, retries while the TG or every slot is
busy, 58 ms per frame, stop on a refused frame, TTS encoded in a
thread. Versioned next to plugins/example.
Core side, found by an end-to-end run of the plugin:
- PluginIngress ends a plugin voice stream that has been silent for a
second without a terminator (frees the slot, monitor END);
- the default max_frames_per_s adds 18 frames/s per group voice TG, so
one stream per TG fits (a voice stream is ~17 frames/s).
