Installation
๐ธTTS is tested on Ubuntu 18.04 with python >= 3.9, < 3.12..
If you are only interested in synthesizing speech with the released ๐ธTTS models, installing from PyPI is the easiest option.
pip install TTS
If you plan to code or train models, clone ๐ธTTS 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, ๐@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 ๐ธTTS
๐ Python API
Running a multi-speaker and multi-lingual model
import torch
from TTS.api import TTS
# Get device
device = "cuda" if torch.cuda.is_available() else "cpu"
# List available ๐ธTTS models
print(TTS().list_models())
# Init TTS
tts = TTS("tts_models/multilingual/multi-dataset/xtts_v2").to(device)
# Run TTS
# โ 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.tts_to_file(text="Hello world!", speaker_wav="my/cloning/audio.wav", language="en", 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).to(device)
# 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).to(device)
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-fr", file_path="output.wav")
tts.tts_to_file("Isso รฉ clonagem de voz.", speaker_wav="my/cloning/audio.wav", language="pt-br", file_path="output.wav")
Example voice conversion
Converting the voice in source_wav
to the voice of target_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")
Example voice cloning together with the voice conversion model.
This way, you can clone voices by using any model in ๐ธTTS.
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"
)
Example text to speech using Fairseq models in ~1100 languages ๐คฏ.
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.
# TTS with on the fly voice conversion
api = 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"
)
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 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
Multi-speaker Models
-
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>
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>
