🐸TTS is a library for advanced Text-to-Speech generation. It's built on the latest research, was designed to achieve the best trade-off among ease-of-training, speed and quality. 🐸TTS comes with pretrained models, tools for measuring dataset quality and already used in 20+ languages for products and research projects.

🥇 TTS Performance

Underlined "TTS*" and "Judy*" are 🐸TTS models

Features

• High-performance Deep Learning models for Text2Speech tasks.
  • Text2Spec models (Tacotron, Tacotron2, Glow-TTS, SpeedySpeech).
  • Speaker Encoder to compute speaker embeddings efficiently.
  • Vocoder models (MelGAN, Multiband-MelGAN, GAN-TTS, ParallelWaveGAN, WaveGrad, WaveRNN)
• Fast and efficient model training.
• Detailed training logs on the terminal and Tensorboard.
• Support for Multi-speaker TTS.
• Efficient, flexible, lightweight but feature complete Trainer API.
• Released and ready-to-use models.
• Tools to curate Text2Speech datasets underdataset_analysis.
• Utilities to use and test your models.
• Modular (but not too much) code base enabling easy implementation of new ideas.

Install TTS

🐸TTS is tested on Ubuntu 18.04 with python >= 3.7, < 3.11..

If you are only interested in synthesizing speech with the released 🐸TTS models, installing from PyPI is the easiest option.

pip install TTS

If you plan to code or train models, clone 🐸TTS and install it locally.

git clone https://github.com/coqui-ai/TTS
pip install -e .[all,dev,notebooks] # Select the relevant extras

If you are on Ubuntu (Debian), you can also run following commands for installation.

$ make system-deps # intended to be used on Ubuntu (Debian). Let us know if you have a different OS.
$ make install

If you are on Windows, 👑@GuyPaddock wrote installation instructions here.

Use TTS

Single Speaker Models

• List provided models:

  $ tts --list_models
  

• Get model info (for both tts_models and vocoder_models):

  • Query by type/name: The model_info_by_name uses the name as it from the --list_models.

    $ tts --model_info_by_name "<model_type>/<language>/<dataset>/<model_name>"
    

    For example:

    $ tts --model_info_by_name tts_models/tr/common-voice/glow-tts
    

    $ tts --model_info_by_name vocoder_models/en/ljspeech/hifigan_v2
    

  • Query by type/idx: The model_query_idx uses the corresponding idx from --list_models.

    $ tts --model_info_by_idx "<model_type>/<model_query_idx>"
    

    For example:

    $ tts --model_info_by_idx tts_models/3 

• Run TTS with default models:

  $ tts --text "Text for TTS" --out_path output/path/speech.wav
  

• Run a TTS model with its default vocoder model:

  $ tts --text "Text for TTS" --model_name "<model_type>/<language>/<dataset>/<model_name>" --out_path output/path/speech.wav
  

  For example:

  $ tts --text "Text for TTS" --model_name "tts_models/en/ljspeech/glow-tts" --out_path output/path/speech.wav
  

• Run with specific TTS and vocoder models from the list:

  $ tts --text "Text for TTS" --model_name "<model_type>/<language>/<dataset>/<model_name>" --vocoder_name "<model_type>/<language>/<dataset>/<model_name>" --out_path output/path/speech.wav
  

  For example:

  $ tts --text "Text for TTS" --model_name "tts_models/en/ljspeech/glow-tts" --vocoder_name "vocoder_models/en/ljspeech/univnet" --out_path output/path/speech.wav
  

• Run your own TTS model (Using Griffin-Lim Vocoder):

  $ tts --text "Text for TTS" --model_path path/to/model.pth --config_path path/to/config.json --out_path output/path/speech.wav
  

• Run your own TTS and Vocoder models:

  $ tts --text "Text for TTS" --model_path path/to/config.json --config_path path/to/model.pth --out_path output/path/speech.wav
  --vocoder_path path/to/vocoder.pth --vocoder_config_path path/to/vocoder_config.json
  

Multi-speaker Models

• List the available speakers and choose as <speaker_id> among them:

  $ tts --model_name "<language>/<dataset>/<model_name>" --list_speaker_idxs
  

• Run the multi-speaker TTS model with the target speaker ID:

  $ tts --text "Text for TTS." --out_path output/path/speech.wav --model_name "<language>/<dataset>/<model_name>" --speaker_idx <speaker_id>
  

• Run your own multi-speaker TTS model:

  $ tts --text "Text for TTS" --out_path output/path/speech.wav --model_path path/to/config.json --config_path path/to/model.pth --speakers_file_path path/to/speaker.json --speaker_idx <speaker_id>
