What it does

A low-latency VAD → STT → LLM → TTS pipeline behind an OpenAI Realtime-compatible WebSocket API, where every stage is replaceable — point the LLM slot at a hosted provider, HF Inference Providers, or your own vLLM or llama.cpp server for a fully local stack. Latency and quality depend entirely on the parts you pick, so run the defaults first. Published by Hugging Face and used in production. Apache-2.0.

speech-to-speech FAQ

Is speech-to-speech free?: Yes. It runs on your own machine, so there is no usage-based cost either.
Do I need to install anything or write code to use speech-to-speech?: It needs the command line. If you are not comfortable typing commands, expect to get stuck during setup.
Does speech-to-speech work on a phone?: No. It needs a computer.
Can I use speech-to-speech commercially?: The licence is Apache-2.0, which permits commercial use. Conditions such as keeping the copyright notice still apply, so read the licence text before shipping it inside something.
