Text-to-Speech (TTS)Synthesize speech from text using swappable backends — browser-native (zero cost) or OpenAI TTS API.Quick StartHow It WorksDefault: BrowserTTSManager — uses the browser's built-in Web Speech API, requires no API key, runs entirely client-side.Optional: OpenAITTSManager — uses OpenAI's TTS API for higher-quality voices (alloy, echo, fable, onyx, nova, shimmer). Requires openai package and API key.ConfigurationREST API| Endpoint | Method | Description ||----------|--------|-------------|| /api/tts/voices | GET | List available voices || /api/tts/synthesize | POST | Synthesize speech from text |GET /api/tts/voicesPOST /api/tts/synthesizeRelatedGateway Chat — Chat can use TTS for voice responses
