Respeecher Space Real-Time TTS API
Low-latency real-time text-to-speech that begins streaming audio in under 200ms via three transports - one-shot bytes (POST /tts/bytes, up to ~5,000 characters), HTTP SSE chunks (POST /tts/sse), and a bidirectional WebSocket channel (wss://api.respeecher.com/v1/public/tts/en-rt, GET /tts/websocket) that streams input text and output audio keyed by context_id. English (en-rt) and Ukrainian (ua-rt) models, X-API-Key auth, official Python and TypeScript SDKs, and LiveKit, Pipecat, Ultravox, and VAPI integrations.
