Build realtime AI apps that can see, hear, and speak
A drag-and-drop App Flow Builder connects inference, logic, and state nodes so you can design complex realtime flows without custom glue code.
Built-in low-latency orchestration for vision-language models, speech-to-text, and text-to-speech in a single pipeline.
Combine video, screen, audio, and text from several streams and participants simultaneously for rich interactive apps.
Mix and match building blocks, or write custom nodes to interface with your own API or SDK so the AI can act on external systems.

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.
