- fall back to the default when VOICE_TIMEOUT_MS is non-numeric or <= 0, so a
bad override can't make the abort fire immediately
- type-check the tts `text` before calling .trim() so a non-string body returns
400 instead of throwing
- abort the in-flight TTS fetch on stop() and on a superseding play, so tapping
read-aloud repeatedly doesn't leave orphaned requests generating audio
drop leftover sidecar/faster-whisper references now that the backend is any
openai-compatible voice api, and add jsdoc to the voice-proxy functions so the
docstring coverage check passes.
Validates the user-supplied backend URL (http/https only, blocks the link-local
metadata range) to prevent SSRF; remaps upstream 401/403 so a bad voice API key
isn't read as the app's own auth failing; adds a client-side AbortController timeout
on the read-aloud request so the button can't sit in loading if a request stalls.
Bumps the proxy timeout to 5 minutes (VOICE_TIMEOUT_MS) since local TTS can
synthesize long messages at roughly real-time, and returns a clear timed-out
message (504) instead of failing silently. The read-aloud button now shows
backend errors.
Switches the voice proxy to the OpenAI audio API (/v1/audio/transcriptions and
/v1/audio/speech) so it works with OpenAI, Groq, or a local server. Adds a
Settings -> Voice tab (base URL, API key, models, voice) plus a Quick Settings
toggle, and removes the bundled Python sidecar.
Review fixes: stop mic tracks on unmount, clear the global TTS stop handler and
revoke leaked blob URLs, add fetch timeouts in the proxy, surface mic errors in
the button, trim before appending transcripts, and drop the repo-wide wav ignore.
Adds a push-to-talk mic button in the composer and a read-aloud button on
assistant messages. Both are opt-in and hidden unless a voice backend is
configured via VOICE_SIDECAR_URL.
The auth-gated /api/voice proxy forwards to a configurable backend exposing
/transcribe and /tts (provider-agnostic); the frontend probes /api/voice/health
and hides the controls when disabled. Adds i18n keys and docs/voice.md.
Includes a local, no-API-key reference backend in voice-sidecar/ (faster-whisper
for STT, Kokoro-82M for TTS, both CPU-capable).
