Replacements
Listings that take over the same core job as Coqui TTS.
Kokoro
Small, fast open-weight text-to-speech model you can run locally.
Kokoro is a small Apache-licensed open-weight model that is fast to run locally, but it offers no training toolkit and has been quiet since mid-2025.
Chatterbox
Open source text-to-speech model with zero-shot voice cloning.
Chatterbox is an MIT licensed text-to-speech model with zero-shot voice cloning from a short sample, used mainly through code.
Tortoise TTS
Open source multi-voice text-to-speech system tuned for quality.
Tortoise TTS is an Apache-2.0 multi-voice system tuned for realistic prosody, notably slower to generate and not updated since late 2024.
Bark
Open source generative audio model for expressive multilingual speech.
Bark is an MIT licensed generative audio model with expressive multilingual speech and nonverbal sounds, but slower and heavier than lightweight TTS options.
OpenVoice
Open source instant voice cloning model with flexible style control.
OpenVoice is an MIT licensed instant voice cloning model with control over emotion and accent, rather than a general training toolkit.
Piper
A fast neural text-to-speech engine that runs locally, even on modest hardware like a Raspberry Pi.
Piper is an actively usable GPL-3.0 TTS engine fast enough for a Raspberry Pi, focused on inference through command line, Python or C rather than training.
F5-TTS
Open-source text-to-speech model that can clone voices, with a local Gradio interface for running it.
F5-TTS clones voices from a short reference recording and adds a local Gradio interface, and it is a large, active project with over 15,000 stars.
GPT-SoVITS
A voice cloning and text-to-speech toolkit that can train a voice from about one minute of audio.
GPT-SoVITS trains custom voices from about a minute of audio with a local web UI, runs on Windows and Linux, and is not open source.
