Respeecher is an AI voice company known for high-fidelity speech-to-speech (STS) voice conversion and text-to-speech (TTS) used across film, television, games, and advertising. It exposes two documented, self-service public APIs. The Voice Marketplace API (gateway.respeecher.com) provides voice discovery, speech-to-speech conversion orders, text-to-speech synthesis, calibration, recordings, projects/folders, credits, and statistics, secured with an API key. The newer Respeecher Space real-time TTS API (api.respeecher.com) streams lifelike audio in under 200ms via one-shot bytes, HTTP SSE, and a WebSocket channel, with English (en-rt) and Ukrainian (ua-rt) models, official Python and TypeScript SDKs, and LiveKit, Pipecat, Ultravox, and VAPI integrations. Bespoke, high-touch voice cloning for studios is delivered through the enterprise AI Voice Lab.
