Real-time voice AI APIs with 50 ms to first audio
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.
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.
WebSocket streaming, Python and Rust SDKs, custom vocabulary, semantic VAD, and code-switching support make integration straightforward for agent builders.
Phonon is Gradium's openly available TTS model that runs on-device for offline or privacy-sensitive deployments.
A general-purpose AI agent that executes tasks, not just answers them
Give the agent a goal and it plans the steps, chooses tools, and works through the task in a cloud environment without constant supervision.
Produces finished artifacts such as slide decks, functional websites, small games, and formatted documents rather than raw text.
Runs broad, multi-source investigations and compiles the findings into a structured report.
Generates images, video, and music as part of a larger task or as standalone outputs.
