	You can also help us implement more models.

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

	If you are only interested in [synthesizing speech](https://tts.readthedocs.io/en/latest/inference.html) 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](https://stackoverflow.com/questions/66726331/how-can-i-run-mozilla-tts-coqui-tts-training-with-cuda-on-a-windows-system).


	## 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](http://[::1]:5002/)
	More details about the docker images (like GPU support) can be found [here](https://tts.readthedocs.io/en/latest/docker_images.html)


	## 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("tts_models/multilingual/multi-dataset/xtts_v2").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.tts_to_file(text="Hello world!", speaker_wav="my/cloning/audio.wav", language="en", file_path="output.wav")
	```

	#### Running a single speaker model

	```python
	# 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 é 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`

	```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("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 using [🐸Coqui Studio](https://coqui.ai) voices.
	You access all of your cloned voices and built-in speakers in [🐸Coqui Studio](https://coqui.ai).
	To do this, you'll need an API token, which you can obtain from the [account page](https://coqui.ai/account).
	After obtaining the API token, you'll need to configure the COQUI_STUDIO_TOKEN environment variable.

	Once you have a valid API token in place, the studio speakers will be displayed as distinct models within the list.
	These models will follow the naming convention `coqui_studio/en/<studio_speaker_name>/coqui_studio`

	```python
	# XTTS model
	models = TTS(cs_api_model="XTTS").list_models()
	# Init TTS with the target studio speaker
	tts = TTS(model_name="coqui_studio/en/Torcull Diarmuid/coqui_studio", progress_bar=False)
	# Run TTS
	tts.tts_to_file(text="This is a test.", language="en", file_path=OUTPUT_PATH)

	# V1 model
	models = TTS(cs_api_model="V1").list_models()
	# Run TTS with emotion and speed control
	# Emotion control only works with V1 model
	tts.tts_to_file(text="This is a test.", file_path=OUTPUT_PATH, emotion="Happy", speed=1.5)
	```

	#### 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](https://dl.fbaipublicfiles.com/mms/tts/all-tts-languages.html)
	and learn about the Fairseq models [here](https://github.com/facebookresearch/fairseq/tree/main/examples/mms).

	```python
	# 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`

	<!-- begin-tts-readme -->

	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 TTS and define speed factor to use for 🐸Coqui Studio models, between 0.0 and 2.0:

	```
	$ tts --text "Text for TTS" --model_name "coqui_studio/<language>/<dataset>/<model_name>" --speed 1.2 --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 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>
	```
