Gradium

Real-time voice AI APIs with 50 ms to first audio

Ultra-low-latency voice models

Text-to-speech, speech-to-text, and live speech-to-speech translation reach roughly 50 ms to first audio, tuned for conversational agents rather than batch processing.

Tiered voice cloning and voice design

Clone a voice from a short sample for everyday use, move up to pro cloning for production quality, or generate a brand-new voice from a text description.

Developer-first API and SDKs

WebSocket streaming, Python and Rust SDKs, custom vocabulary, semantic VAD, and code-switching support make integration straightforward for agent builders.
