# Miso-TTS

> Open-source emotive text-to-speech foundation model with low conversational latency.

Miso-TTS is an open-source 8B parameter speech synthesis foundation model developed by Miso Labs. It generates expressive, human-like voice with a fast 110ms response latency and supports one-shot voice cloning. The model can be run locally on-premises or accessed via an API, allowing developers to build real-time voice agents without third-party data exposure.
