Built for Voice Agents

Our Text-to-Speech (TTS) models are made specifically for voice-agent companies and designed to work reliably in real production environments.

Our main model, SILMA TTS v2.0, reaches 170 ms TTFT on the server and is trained only on conversational speech. It’s built for large-scale deployment, giving you strong control over speaking speed and how the voice varies, and it also supports voice cloning.
