In their own words
Chatterbox TTS
Chatterbox TTS is a family of open-source text-to-speech models from Resemble AI. Its listed choices include Turbo, Nano, Multilingual V3, and dedicated single-language models. Turbo supports tags that can prompt reactions such as sighs, gasps, coughs, and laughter; Nano is intended for on-device or CPU use when memory and latency budgets are tight. The README lists 23 languages for Multilingual. The project supports voice cloning, audio input, batch processing, voice isolation, and WAV export. Generated audio carries Resemble AI’s PerTh watermark. The repository is MIT licensed, and its listed plan costs nothing for research and development. Resemble says it has stopped offering voice generation as a commercial product, while its models remain open and free for research and development. The README provides pip and source installation instructions and describes Python 3.11 on Debian 11, with CUDA, CPU, and MPS device options. Listed platforms are Linux, macOS, and self-hosted.
VoiceStudio
VoiceStudio is an open-source voice AI studio for local voice cloning, voice design, video dubbing, dictation, transcription and audiobook creation. Users can describe a voice by gender, age, accent, pitch and emotion without providing reference audio. Its dubbing workflow transcribes and translates video, then re-voices it while keeping speakers separate and aligning timing with the original. Users can create multi-voice audio from scripts and chaptered audiobooks from long text or EPUB files. The desktop app exposes a local OpenAI-compatible API for speech, voices, transcription and dubbing. The maker lists 26 adapters, including local text-to-speech and transcription engines and a configured-remote ASR adapter. The maker says recordings, generated audio, transcripts and derived voice data stay on user-controlled storage and are not received by its website or control plane. The app may access the network for updates, model downloads or explicitly network-backed adapters. The public build has no hosted dashboard or Cloud API. Open Source costs nothing under AGPL-3.0; Pro costs $99 a year and Lifetime costs $299, paid once. Speech model licences are separate.
