An open source implementation of Microsoft's [VALL-E X](https://arxiv.org/pdf/2303.03926) zero-shot TTS model.
**We release our trained model to the public for research or application usage.** ![vallex-framework](/images/vallex_framework.jpg "VALL-E X framework") VALL-E X is an amazing multilingual text-to-speech (TTS) model proposed by Microsoft. While Microsoft initially publish in their research paper, they did not release any code or pretrained models. Recognizing the potential and value of this technology, our team took on the challenge to reproduce the results and train our own model. We are glad to share our trained VALL-E X model with the community, allowing everyone to experience the power next-generation TTS! ๐ŸŽง

๐Ÿช‘ Basics

 ```python from utils.generation import SAMPLE_RATE, generate_audio, preload_models from scipy.io.wavfile import write as write_wav from IPython.display import Audio # download and load all models preload_models() # generate audio from text text_prompt = """ Hello, my name is Nose. And uh, and I like hamburger. Hahaha... But I also have other interests such as playing tactic toast. """ audio_array = generate_audio(text_prompt) # save audio to disk write_wav("vallex_generation.wav", SAMPLE_RATE, audio_array) # play text in notebook Audio(audio_array, rate=SAMPLE_RATE) ``` [hamburger.webm](https://github.com/Plachtaa/VALL-E-X/assets/112609742/578d7bbe-cda9-483e-898c-29646edc8f2e)

๐ŸŒŽ Foreign Language
This VALL-E X implementation also supports Chinese and Japanese. All three languages have equally awesome performance!
```python text_prompt = """ ใƒใƒฅใ‚ฝใ‚ฏใฏ็งใฎใŠๆฐ—ใซๅ…ฅใ‚Šใฎ็ฅญใ‚Šใงใ™ใ€‚ ็งใฏๆ•ฐๆ—ฅ้–“ไผ‘ใ‚“ใงใ€ๅ‹ไบบใ‚„ๅฎถๆ—ใจใฎๆ™‚้–“ใ‚’้Žใ”ใ™ใ“ใจใŒใงใใพใ™ใ€‚ """ audio_array = generate_audio(text_prompt) ``` [vallex_japanese.webm](https://github.com/Plachtaa/VALL-E-X/assets/112609742/ee57a688-3e83-4be5-b0fe-019d16eec51c) *Note: VALL-E X controls accent perfectly even when synthesizing code-switch text. However, you need to manually denote language of respective sentences (since our g2p tool is rule-base)* ```python text_prompt = """ [EN]The Thirty Years' War was a devastating conflict that had a profound impact on Europe.[EN] [ZH]่ฟ™ๆ˜ฏๅŽ†ๅฒ็š„ๅผ€ๅง‹ใ€‚ ๅฆ‚ๆžœๆ‚จๆƒณๅฌๆ›ดๅคš๏ผŒ่ฏท็ปง็ปญใ€‚[ZH] """ audio_array = generate_audio(text_prompt, language='mix') ``` [vallex_codeswitch.webm](https://github.com/Plachtaa/VALL-E-X/assets/112609742/d8667abf-bd08-499f-a383-a861d852f98a)

๐Ÿ“ผ Voice Presets

 VALL-E X provides tens of speaker voices which you can directly used for inference! Browse all voices in the [code](/presets) > VALL-E X tries to match the tone, pitch, emotion and prosody of a given preset. The model also attempts to preserve music, ambient noise, etc. ```python text_prompt = """ I am an innocent boy with a smoky voice. It is a great honor for me to speak at the United Nations today. """ audio_array = generate_audio(text_prompt, prompt="dingzhen") ``` [smoky.webm](https://github.com/Plachtaa/VALL-E-X/assets/112609742/d3f55732-b1cd-420f-87d6-eab60db14dc5)

๐ŸŽ™Voice Cloning

 VALL-E X supports voice cloning! You can make a voice prompt with any person, character or even your own voice, and use it like other voice presets.
To make a voice prompt, you need to provide a speech of 3~10 seconds long, as well as the transcript of the speech. You can also leave the transcript blank to let the [Whisper](https://github.com/openai/whisper) model to generate the transcript. > VALL-E X tries to match the tone, pitch, emotion and prosody of a given prompt. The model also attempts to preserve music, ambient noise, etc. ```python from utils.prompt_making import make_prompt ### Use given transcript make_prompt(name="paimon", audio_prompt_path="paimon_prompt.wav", transcript="Just, what was that? Paimon thought we were gonna get eaten.") ### Alternatively, use whisper make_prompt(name="paimon", audio_prompt_path="paimon_prompt.wav") ``` Now let's try out the prompt we've just made! ```python from utils.generation import SAMPLE_RATE, generate_audio, preload_models from scipy.io.wavfile import write as write_wav # download and load all models preload_models() text_prompt = """ Hey, Traveler, Listen to this, This machine has taken my voice, and now it can talk just like me! """ audio_array = generate_audio(text_prompt, prompt="paimon") write_wav("paimon_cloned.wav", SAMPLE_RATE, audio_array) ``` [paimon_prompt.webm](https://github.com/Plachtaa/VALL-E-X/assets/112609742/e7922859-9d12-4e2a-8651-e156e4280311) [paimon_cloned.webm](https://github.com/Plachtaa/VALL-E-X/assets/112609742/60d3b7e9-5ead-4024-b499-a897ce5f3d5e)

๐ŸŽขUser Interface

 Not comfortable with codes? No problem! We've also created a user-friendly graphical interface for VALL-E X. It allows you to interact with the model effortlessly, making voice cloning and multilingual speech synthesis a breeze.
You can launch the UI by the following command: ```commandline python -X utf8 launch-ui.py ```
## ๐Ÿ› ๏ธ Hardware and Inference Speed VALL-E X works well on both CPU and GPU (`pytorch 2.0+`, CUDA 11.7 and CUDA 12.0). A GPU VRAM of 6GB is enough for running VALL-E X without offloading. ## โš™๏ธ Details VALL-E X is similar to [Bark](https://github.com/suno-ai/bark), [VALL-E](https://arxiv.org/abs/2301.02111) and [AudioLM](https://arxiv.org/abs/2209.03143), which generates audio in GPT-style by predicting audio tokens quantized by [EnCodec](https://github.com/facebookresearch/encodec).
Comparing to [Bark](https://github.com/suno-ai/bark): - โœ” **Light-weighted**: 3๏ธโƒฃ โœ– smaller, - โœ” **Efficient**: 4๏ธโƒฃ โœ– faster, - โœ” **Better quality on Chinese & Japanese** - โœ” **Cross-lingual speech without foreign accent** - โœ” **Easy voice-cloning** - โŒ **Less languages** - โŒ **No special tokens for music / sound effects** ### Supported Languages | Language | Status | | --- | :---: | | English (en) | โœ… | | Japanese (ja) | โœ… | | Chinese, simplified (zh) | โœ… | ## โ“ FAQ #### Where is code for training? * [lifeiteng's vall-e](https://github.com/lifeiteng/vall-e) has almost everything. There is no plan to release our training code because there is no difference between lifeiteng's implementation. #### Where can I download the model checkpoint? * We use `wget` to download the model to directory `./checkpoints/` when you run the program for the first time. * If the download fails on the first run, please manually download from [this link](https://huggingface.co/Plachta/VALL-E-X/resolve/main/vallex-checkpoint.pt), and put the file under directory `./checkpoints/`. #### How much VRAM do I need? * 6GB GPU VRAM - Almost all NVIDIA GPUs satisfy the requirement. #### Why the model fails to generate long text? * Transformer's computation complexity increases quadratically while the sequence length increases. Hence, all training are kept under 22 seconds. Please make sure the total length of audio prompt and generated audio is less than 22 seconds to ensure acceptable performance. #### MORE TO BE ADDED... ## ๐Ÿง  TODO - [x] Add Chinese README - [x] Long text generation - [x] Replace Encodec decoder with Vocos decoder - [ ] Fine-tuning for better voice adaptation - [ ] `.bat` scripts for non-python users - [ ] To be added... ## ๐Ÿ™ Appreciation - [VALL-E X paper](https://arxiv.org/pdf/2303.03926) for the brilliant idea - [lifeiteng's vall-e](https://github.com/lifeiteng/vall-e) for related training code - [bark](https://github.com/suno-ai/bark) for the amazing pioneering work in neuro-codec TTS model ## โญ๏ธ Show Your Support If you find VALL-E X interesting and useful, give us a star on GitHub! โญ๏ธ It encourages us to keep improving the model and adding exciting features. ## ๐Ÿ“œ License VALL-E X is licensed under the [MIT License](./LICENSE). --- Have questions or need assistance?
