Underlined "TTS*" and "Judy*" areinternal 🐸TTS models that are not released open-source. They are here to show the potential. Models prefixed with a dot (.Jofish .Abe and .Janice) are real human voices.

• 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 completeTrainer 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.

You can also help us implement more models.

🐸TTS is tested on Ubuntu 18.04 withpython >= 3.9, < 3.12..

If you are only interested insynthesizing 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/TTSpip 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 instructionshere.

You can also try TTS without install with the docker image.Simply run the following command and you will be able to run TTS without installing it.

docker run --rm -it -p 5002:5002 --entrypoint /bin/bash ghcr.io/coqui-ai/tts-cpupython3 TTS/server/server.py --list_models#To get the list of available modelspython3 TTS/server/server.py --model_name tts_models/en/vctk/vits# To start a server

You can then enjoy the TTS serverhereMore details about the docker images (like GPU support) can be foundhere

Converting the voice insource_wav to the voice oftarget_wav

tts=TTS(model_name="voice_conversion_models/multilingual/vctk/freevc24",progress_bar=False).to("cuda")tts.voice_conversion_to_file(source_wav="my/source.wav",target_wav="my/target.wav",file_path="output.wav")

This way, you can clone voices by using any model in 🐸TTS.

tts=TTS("tts_models/de/thorsten/tacotron2-DDC")tts.tts_with_vc_to_file("Wie sage ich auf Italienisch, dass ich dich liebe?",speaker_wav="target/speaker.wav",file_path="output.wav")

For Fairseq models, use the following name format:tts_models/<lang-iso_code>/fairseq/vits.You can find the language ISO codeshereand learn about the Fairseq modelshere.

# TTS with on the fly voice conversionapi=TTS("tts_models/deu/fairseq/vits")api.tts_with_vc_to_file("Wie sage ich auf Italienisch, dass ich dich liebe?",speaker_wav="target/speaker.wav",file_path="output.wav")

Synthesize speech on command line.

You can either use your trained model or choose a model from the provided list.

If you don't specify any models, then it uses LJSpeech based English model.

• 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

  • Query info for model info by full name:

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

• Run TTS with default models:

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

• Run TTS and pipe out the generated TTS wav file data:

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

• 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/model.pth --config_path path/to/config.json --out_path output/path/speech.wav    --vocoder_path path/to/vocoder.pth --vocoder_config_path path/to/vocoder_config.json

• List the available speakers and choose a <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/model.pth --config_path path/to/config.json --speakers_file_path path/to/speaker.json --speaker_idx <speaker_id>

$ tts --out_path output/path/speech.wav --model_name "<language>/<dataset>/<model_name>" --source_wav <path/to/speaker/wav> --target_wav <path/to/reference/wav>
