VoiceCraft: Zero-Shot Speech Editing and Text-to-Speech in the Wild

TL;DR

VoiceCraft is a token infilling neural codec language model, that achieves state-of-the-art performance on both speech editing and zero-shot text-to-speech (TTS) on in-the-wild data including audiobooks, internet videos, and podcasts.

To clone or edit an unseen voice, VoiceCraft needs only a few seconds of reference.

How to run inference

There are three ways (besides running Gradio in Colab):

1. More flexible inference beyond Gradio UI in Google Colab. see quickstart colab
2. with docker. see quickstart docker
3. without docker. see environment setup. You can also run gradio locally if you choose this option
4. As a standalone script that you can easily integrate into other projects. see quickstart command line.

When you are inside the docker image or you have installed all dependencies, Checkout inference_tts.ipynb.

If you want to do model development such as training/finetuning, I recommend following envrionment setup and training.

News

:star: 03/15/2025: change inference sampling from topp=1 to topk=40 massively improve editing and TTS performance

:star: 04/22/2024: 330M/830M TTS Enhanced Models are up here, load them through gradio_app.py or inference_tts.ipynb! Replicate demo is up, major thanks to @chenxwh!

:star: 04/11/2024: VoiceCraft Gradio is now available on HuggingFace Spaces here! Major thanks to @zuev-stepan, @Sewlell, @pgsoar @Ph0rk0z.

:star: 04/05/2024: I finetuned giga330M with the TTS objective on gigaspeech and 1/5 of librilight. Weights are here. Make sure maximal prompt + generation length <= 16 seconds (due to our limited compute, we had to drop utterances longer than 16s in training data). Even stronger models forthcomming, stay tuned!

:star: 03/28/2024: Model weights for giga330M and giga830M are up on HuggingFace🤗 here!

QuickStart Colab

:star: To try out speech editing or TTS Inference with VoiceCraft, the simplest way is using Google Colab. Instructions to run are on the Colab itself.

1. To try Speech Editing
2. To try TTS Inference

QuickStart Command Line

:star: To use it as a standalone script, check out tts_demo.py and speech_editing_demo.py. Be sure to first setup your environment. Without arguments, they will run the standard demo arguments used as an example elsewhere in this repository. You can use the command line arguments to specify unique input audios, target transcripts, and inference hyperparameters. Run the help command for more information: python3 tts_demo.py -h

QuickStart Docker

:star: To try out TTS inference with VoiceCraft, you can also use docker. Thank @ubergarm and @jayc88 for making this happen.

Tested on Linux and Windows and should work with any host with docker installed.

# 1. clone the repo on in a directory on a drive with plenty of free space
git clone git@github.com:jasonppy/VoiceCraft.git
cd VoiceCraft

# 2. assumes you have docker installed with nvidia container container-toolkit (windows has this built into the driver)
# https://docs.nvidia.com/datacenter/cloud-native/container-toolkit/1.13.5/install-guide.html
# sudo apt-get install -y nvidia-container-toolkit-base || yay -Syu nvidia-container-toolkit || echo etc...

# 3. First build the docker image
docker build --tag "voicecraft" .

# 4. Try to start an existing container otherwise create a new one passing in all GPUs
./start-jupyter.sh  # linux
start-jupyter.bat   # windows

# 5. now open a webpage on the host box to the URL shown at the bottom of:
docker logs jupyter

# 6. optionally look inside from another terminal
docker exec -it jupyter /bin/bash
export USER=(your_linux_username_used_above)
export HOME=/home/$USER
sudo apt-get update

# 7. confirm video card(s) are visible inside container
nvidia-smi

# 8. Now in browser, open inference_tts.ipynb and work through one cell at a time
echo GOOD LUCK

Inference Examples

Checkout inference_speech_editing.ipynb and inference_tts.ipynb

Gradio

Run in colab

Run locally

After environment setup install additional dependencies:

apt-get install -y espeak espeak-data libespeak1 libespeak-dev
apt-get install -y festival*
apt-get install -y build-essential
apt-get install -y flac libasound2-dev libsndfile1-dev vorbis-tools

pip install -r gradio_requirements.txt

Run gradio server from terminal or gradio_app.ipynb:

python gradio_app.py

It is ready to use on default url.

How to use it

1. (optionally) Select models
2. Load models
3. Transcribe
4. (optionally) Tweak some parameters
5. Run
6. (optionally) Rerun part-by-part in Long TTS mode

Some features

Smart transcript: write only what you want to generate

TTS mode: Zero-shot TTS

Edit mode: Speech editing

Long TTS mode: Easy TTS on long texts

Training

To train an VoiceCraft model, you need to prepare the following parts:

1. utterances and their transcripts
2. encode the utterances into codes using e.g. Encodec
3. convert transcripts into phoneme sequence, and a phoneme set (we named it vocab.txt)
4. manifest (i.e. metadata)

Step 1,2,3 are handled in ./data/phonemize_encodec_encode_hf.py, where

1. Gigaspeech is downloaded through HuggingFace. Note that you need to sign an agreement in order to download the dataset (it needs your auth token)
2. phoneme sequence and encodec codes are also extracted using the script.

An example run:

conda activate voicecraft
export CUDA_VISIBLE_DEVICES=0
cd ./data
python phonemize_encodec_encode_hf.py \
--dataset_size xs \
--download_to path/to/store_huggingface_downloads \
--save_dir path/to/store_extracted_codes_and_phonemes \
--encodec_model_path path/to/encodec_model \
--mega_batch_size 120 \
--batch_size 32 \
--max_len 30000

where encodec_model_path is avaliable here. This model is trained on Gigaspeech XL, it has 56M parameters, 4 codebooks, each codebook has 2048 codes. Details are described in our paper. If you encounter OOM during extraction, try decrease the batch_size and/or max_len. The extracted codes, phonemes, and vocab.txt will be stored at path/to/store_extracted_codes_and_phonemes/${dataset_size}/{encodec_16khz_4codebooks,phonemes,vocab.txt}.
