🥇 TTS Performance

Underlined "TTS" and "Judy" are internal 🐸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.

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.

Installation

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

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

bash pip install TTS

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

bash 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.

bash $ 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.

Docker Image

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.

bash docker run --rm -it -p 5002:5002 --entrypoint /bin/bash ghcr.io/coqui-ai/tts-cpu python3 TTS/server/server.py --list_models #To get the list of available models python3 TTS/server/server.py --model_name tts_models/en/vctk/vits # To start a server

You can then enjoy the TTS server here More details about the docker images (like GPU support) can be found here

Synthesizing speech by 🐸TTS

🐍 Python API

Running a multi-speaker and multi-lingual model

```python import torch from TTS.api import TTS

Get device

device = "cuda" if torch.cuda.is_available() else "cpu"

List available 🐸TTS models

print(TTS().list_models())

Init TTS

tts = TTS("ttsmodels/multilingual/multi-dataset/xttsv2").to(device)

Run TTS

❗ Since this model is multi-lingual voice cloning model, we must set the target speaker_wav and language

Text to speech list of amplitude values as output

wav = tts.tts(text="Hello world!", speaker_wav="my/cloning/audio.wav", language="en")

Text to speech to a file

tts.ttstofile(text="Hello world!", speakerwav="my/cloning/audio.wav", language="en", filepath="output.wav") ```

Running a single speaker model

```python

Init TTS with the target model name

tts = TTS(modelname="ttsmodels/de/thorsten/tacotron2-DDC", progress_bar=False).to(device)

Run TTS

tts.ttstofile(text="Ich bin eine Testnachricht.", filepath=OUTPUTPATH)

Example voice cloning with YourTTS in English, French and Portuguese

tts = TTS(modelname="ttsmodels/multilingual/multi-dataset/yourtts", progressbar=False).to(device) tts.ttstofile("This is voice cloning.", speakerwav="my/cloning/audio.wav", language="en", filepath="output.wav") tts.ttstofile("C'est le clonage de la voix.", speakerwav="my/cloning/audio.wav", language="fr-fr", filepath="output.wav") tts.ttstofile("Isso é clonagem de voz.", speakerwav="my/cloning/audio.wav", language="pt-br", filepath="output.wav") ```

Example voice conversion

Converting the voice in source_wav to the voice of target_wav

python 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")

Example voice cloning together with the voice conversion model.

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

```python

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

Example text to speech using Fairseq models in ~1100 languages 🤯.

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

```python

TTS with on the fly voice conversion

api = TTS("ttsmodels/deu/fairseq/vits") api.ttswithvctofile( "Wie sage ich auf Italienisch, dass ich dich liebe?", speakerwav="target/speaker.wav", file_path="output.wav" ) ```

Command-line tts

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.

Single Speaker Models

• List provided models:

$ tts --list_models

• Get model info (for both ttsmodels and vocodermodels):

  • Query by type/name: The modelinfobyname uses the name as it from the --listmodels. $ 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 modelqueryidx 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

Multi-speaker Models

• List the available speakers and choose a 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>

Voice Conversion Models

$ 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>
