What is Voicebox?

Open source voice cloning desktop application with support for multiple TTS engines that allows users to clone any voice and generate natural speech locally.

Voicebox is a Voice/Audio open-source desktop application that enables local voice cloning and text-to-speech generation across multiple TTS engines, with pricing that is completely free under the MIT license. It is built for developers, game designers, content creators, and privacy-conscious users who need professional voice synthesis without cloud dependencies, API keys, or per-character fees.

The application bundles seven distinct TTS engines — Qwen3-TTS (1.7B and 0.6B parameter variants by Alibaba), Chatterbox and Chatterbox Turbo (by Resemble AI, 350M params), LuxTTS (by ZipVoice, 48kHz output), Qwen CustomVoice (with nine preset speakers), TADA (by Hume AI, 3B and 1B variants), and Kokoro (by hexgrad, 82M params under Apache 2.0). Together these engines cover up to 23 languages, support delivery instructions in natural language, handle paralinguistic tags like [laugh] and [sigh], and deliver performance exceeding 150x realtime on CPU with approximately 1GB VRAM. The TADA engine can produce 700+ seconds of coherent long-form audio without drift, making it viable for audiobook production.

✓Multi-engine TTS architecture with 7 supported models

✓Local-first inference — no cloud, no API keys, no rate limits

✓Voice cloning from a few seconds of audio

✓Multi-voice project composition

✓Built-in REST API on localhost

❌Cons

•Requires local hardware capable of running multi-billion-parameter models (TADA 3B, Qwen 1.7B) for best quality
•No cloud sync, team collaboration, or hosted inference — everything is tied to the user's single machine
•Voice cloning quality depends on engine chosen and user's ability to match engine to task, adding complexity
