# qwen3\_tts\_rs

> Rust-based inference CLI and API server for Qwen3 TTS with voice cloning

qwen3\_tts\_rs is a native Rust implementation for Qwen3 text-to-speech model inference. It packages TTS, voice cloning, and an OpenAI-compatible audio API server into standalone CLI binaries without requiring a Python runtime. It supports hardware acceleration using Apple Silicon MLX via Metal GPU as well as libtorch with NVIDIA CUDA.

## What it is for

- Synthesize speech locally from text using CLI commands or agent workflows
- Clone target voices from short reference audio clips using the Qwen3 base model
- Host a local OpenAI-compatible /v1/audio/speech server for AI agents
- Integrate voice generation skills into autonomous agent frameworks like OpenClaw

## Features

- Self-contained binary builds without Python runtime dependencies
- Apple Silicon acceleration via native MLX and Metal GPU
- Linux and NVIDIA CUDA acceleration via libtorch
- Voice cloning mode using reference audio and transcript prompts
- Predefined named speaker voices including Vivian, Serena, and Ryan
- Voice style and emotion control via natural language instructions on supported models
- OpenAI-compatible HTTP API server (/v1/audio/speech)
- Audio encoding support across multiple formats including WAV, MP3, FLAC, and OGG Opus
