• Install the TTS using the instructions below - only for synthesizing
• Run the server such as the following and then go to http://localhost:5002/
• Input the normalized Sinhala or Pali text - you can use the tool here https://pitaka.lk/tools/converter.html for converting Sinhala letters to Roman

source venv/bin/activate
python TTS/server/server.py --config_path ../models/sinhala/single-v2.1/config.json --model_path ../models/sinhala/single-v2.1/checkpoint_80000.pth

For multispeaker you may also want to edit the speaker path within the config.json file

python TTS/server/server.py --config_path ../models/sinhala/multi-v2.0/config.json --speakers_file_path ../models/sinhala/multi-v2.0/speakers.pth --model_path ../models/sinhala/multi-v2.0/checkpoint_70000.pth

For training there is a notebook in the /notebooks folder in this repository

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.

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.

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

from TTS.api import TTS

# Running a multi-speaker and multi-lingual model

# List available 🐸TTS models and choose the first one
model_name = TTS.list_models()[0]
# Init TTS
tts = TTS(model_name)
# Run TTS
# ❗ Since this model is multi-speaker and multi-lingual, we must set the target speaker and the language
# Text to speech with a numpy output
wav = tts.tts("This is a test! This is also a test!!", speaker=tts.speakers[0], language=tts.languages[0])
# Text to speech to a file
tts.tts_to_file(text="Hello world!", speaker=tts.speakers[0], language=tts.languages[0], file_path="output.wav")

# Running a single speaker model

# Init TTS with the target model name
tts = TTS(model_name="tts_models/de/thorsten/tacotron2-DDC", progress_bar=False, gpu=False)
# Run TTS
tts.tts_to_file(text="Ich bin eine Testnachricht.", file_path=OUTPUT_PATH)

# Example voice cloning with YourTTS in English, French and Portuguese:
tts = TTS(model_name="tts_models/multilingual/multi-dataset/your_tts", progress_bar=False, gpu=True)
tts.tts_to_file("This is voice cloning.", speaker_wav="my/cloning/audio.wav", language="en", file_path="output.wav")
tts.tts_to_file("C'est le clonage de la voix.", speaker_wav="my/cloning/audio.wav", language="fr", file_path="output.wav")
tts.tts_to_file("Isso é clonagem de voz.", speaker_wav="my/cloning/audio.wav", language="pt", file_path="output.wav")

Command line 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/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 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/model.pth --config_path path/to/config.json --speakers_file_path path/to/speaker.json --speaker_idx <speaker_id>
