    Use Cases & Benefits

    • Provides a fast, controllable text-to-speech synthesis toolkit supporting over 7000 languages using deep learning and PyTorch.
    • Enables massively multilingual TTS with precise control over prosody and speaker embeddings, requiring minimal compute resources.
    • Use for developing multilingual voice assistants that require natural speech synthesis in diverse languages.
    • Use for academic research on low-resource and zero-shot multispeaker TTS with articulatory and prosody cloning features.
    • Use for creating accessible reading tools that convert text to speech with customizable pitch, duration, and energy parameters.

    General guidance from repository metadata, not legal advice. How we score

    From the README

    IMS Toucan is a toolkit for training, using, and teaching state-of-the-art Text-to-Speech Synthesis, developed at the Institute for Natural Language Processing (IMS), University of Stuttgart, Germany, official home of the massively multilingual ToucanTTS system. Our system is fast, controllable, and doesn't require a ton of compute.

    If you find this repo useful, consider giving it a star. ⭐ Large numbers make me happy, and they are very motivating. If you want to motivate me even more, you can even consider sponsoring this toolkit. We only use GitHub Sponsors for this, there are scammers on other platforms that pretend to be the creator. Don't let them fool you. The code and the models are absolutely free, and thanks to the generous support of Hugging Face🤗, we even have an instance of the model running on GPU free for anyone to use.
