Authors Published October 13, 2026 Share Published October 13, 2026 Gradium TTS is built for real-time voice agents, achieving TTFA faster than typical human response times through its Delayed Streams Modeling architecture and GPU optimizations, including kernel fusion and CUDA Graphs.
It is available in Baseten's Model Library now as a dedicated deployment.
Gradium TTS: TTFA faster than human speech Gradium’s text-to-speech (TTS) model converts written text into spoken audio and is designed specifically for real-time AI voice agent interactions.
Time-to-First-Audio (TTFA) measures the duration between sending a TTS request and receiving the first playable audio.
It is critical for natural-sounding conversations.
To deliver reliably natural conversations, Gradium TTS achieves a TTFA faster than human speech response times.
