Replacements
Listings that take over the same core job as F5-TTS.
Chatterbox
Open source text-to-speech model with zero-shot voice cloning.
Chatterbox also offers zero-shot voice cloning from a short sample under the MIT license, but it has no dedicated GUI and is mainly used through code.
GPT-SoVITS
A voice cloning and text-to-speech toolkit that can train a voice from about one minute of audio.
GPT-SoVITS trains a custom voice from about a minute of audio with a local web UI, but it runs on Windows and Linux only and is not open source.
OpenVoice
Open source instant voice cloning model with flexible style control.
OpenVoice adds fine control over emotion and accent when cloning a voice, is MIT licensed, and has had no repository update since April 2025.
Coqui TTS
Deep learning toolkit for training and running text-to-speech models.
Coqui TTS is a full MPL-2.0 toolkit for training and running speech models in many languages, though it has had no update since mid-2024.
Tortoise TTS
Open source multi-voice text-to-speech system tuned for quality.
Tortoise TTS is an Apache-2.0 multi-voice system focused on realistic prosody, but it generates speech notably slower and has not been updated since late 2024.
Bark
Open source generative audio model for expressive multilingual speech.
Bark generates expressive multilingual speech with nonverbal sounds like laughter under the MIT license, but it is slower and more resource-intensive.
Kokoro
Small, fast open-weight text-to-speech model you can run locally.
Kokoro is a small, fast Apache-licensed speech model that runs cheaply locally, but it is used as a Python library without voice-cloning features listed.
Piper
A fast neural text-to-speech engine that runs locally, even on modest hardware like a Raspberry Pi.
Piper is a fast GPL-3.0 speech engine that runs even on a Raspberry Pi, but it offers chosen voice models rather than voice cloning.
