Adds text-to-speech that synthesizes higher-quality audio (Google Cloud
TTS) and plays it on a speaker via the /speaker endpoint. Because Cloud
TTS returns audio bytes (not a fetchable URL), the service caches the
clip and hosts it at GET /media/tts/{id}, mirroring the "ding" endpoint,
then points the speaker at that local URL.
The design is a pluggable Provider interface (pkg/service/tts) wrapping
two modes:
- translate: hands the speaker the (undocumented) Google Translate URL
directly (no credentials), reusing models.BuildTranslateTTSURL.
- google-cloud: REST API key auth (no SDK/gRPC), bytes cached locally.
Surfaces:
- service: POST /mgmt/tts/speak, GET /mgmt/tts/config, GET /media/tts/{id};
configured via TTS_PROVIDER / TTS_GOOGLE_API_KEY / TTS_LANGUAGE /
TTS_VOICE / TTS_APP_KEY / TTS_VOLUME.
- CLI: `soundtouch-cli tts speak` (calls the service with mgmt Basic Auth).
- web: a "TTS" source view (like Play URL / TuneIn), proxied to the
service via /api/device-speak/{id}.
The /speaker app_key requirement and model limitations still apply; see
docs/content/docs/reference/SPEAKER-ENDPOINT.md.
