Key point

Hugging Face has released a local voice conversation pipeline that connects VAD, STT, LLM, and TTS.

Details

Hugging Face has released the Speech To Speech project, which enables the construction of a complete voice conversation pipeline in a local environment using open-source models.

This pipeline operates through a four-stage flow: when a user speaks, it detects the voice using VAD (Voice Activity Detection), converts it to text via STT (Speech-to-Text), generates a response with an LLM, and outputs the voice using TTS (Text-to-Speech).

Each stage runs in a separate thread and is connected via queues to minimize processing latency and support efficient parallel processing.
