ChatTTS WebUI & API

A simple local web interface to convert text to speech using ChatTTS. It supports mixed Chinese, English, and numbers, and provides an API.

Original ChatTTS project

UI Preview

The model will be downloaded automatically on the first launch. It will try connecting to https://huggingface.co first. If unreachable, it will download from ModelScope (modelscope.cn).

Please ensure you have a stable internet connection (a VPN may be needed in some regions) when deploying from source to avoid download failures.

Windows Pre-packaged Version

1. Download the zip file from Releases, extract it, and double-click app.exe to start.
2. Some antivirus software may trigger false positives. You can temporarily disable them or deploy from source instead.
3. GPU acceleration will be enabled if you have an NVIDIA card with more than 4GB VRAM and CUDA 12.8+ installed.

Linux Source Deployment

1. Set up a Python 3.9–3.11 environment.

2. Create an empty directory /data/chattts and run: cd /data/chattts && git clone https://github.com/jianchang512/chatTTS-ui .

3. Create a virtual environment: python3 -m venv venv

4. Activate the virtual environment: source ./venv/bin/activate

5. Install dependencies: pip3 install -r requirements.txt

6. For CPU-only (no CUDA acceleration), run:

   pip3 install torch==2.7.1 torchaudio==2.7.1

   For GPU acceleration (CUDA), run:

   pip install torch==2.7.1 torchaudio==2.7.1 --index-url https://download.pytorch.org/whl/cu128
   pip install nvidia-cublas-cu11 nvidia-cudnn-cu11
   

   You will also need to install the CUDA 12.8+ Toolkit yourself.

7. Run python3 app.py to start. A browser window will open automatically at the default address http://127.0.0.1:9966. (Note: By default, the model is downloaded from ModelScope. Please turn off your proxy/VPN during this download, as proxies are not supported for ModelScope).

macOS Source Deployment

1. Set up a Python 3.9–3.11 environment, install Git, and run: brew install libsndfile git [email protected] Then run:

   export PATH="/usr/local/opt/[email protected]/bin:$PATH"
   source ~/.bash_profile 
   source ~/.zshrc
   

2. Create an empty directory /data/chattts and run: cd /data/chattts && git clone https://github.com/jianchang512/chatTTS-ui .

3. Create a virtual environment: python3 -m venv venv

4. Activate the virtual environment: source ./venv/bin/activate

5. Install dependencies: pip3 install -r requirements.txt

6. Install Torch: pip3 install torch==2.7.1 torchaudio==2.7.1

7. Run python3 app.py to start. A browser window will open automatically at http://127.0.0.1:9966.

Windows Source Deployment

1. Download and install Python 3.9–3.11. Make sure to check "Add Python to environment variables" during installation.

2. Download and install Git: https://github.com/git-for-windows/git/releases/download/v2.45.1.windows.1/Git-2.45.1-64-bit.exe

3. Create an empty folder named D:/chattts. Open the folder, type cmd in the address bar, press Enter, and run: git clone https://github.com/jianchang512/chatTTS-ui .

4. Create a virtual environment: python -m venv venv

5. Activate the virtual environment: .\venv\Scripts\activate

6. Install dependencies: pip install -r requirements.txt

7. For CPU-only (no CUDA acceleration):

   Run pip install torch==2.7.1 torchaudio==2.7.1

   For GPU acceleration (CUDA), run:

   pip install torch==2.7.1 torchaudio==2.7.1 --index-url https://download.pytorch.org/whl/cu128

   You will also need to install the CUDA 12.8+ Toolkit yourself.

Docker Deployment (Linux)

Installation

1. Clone the repository

   Clone the project into any directory, for example:

   git clone https://github.com/jianchang512/ChatTTS-ui.git chat-tts-ui
   

2. Start the Container

   Navigate to the project directory:

   cd chat-tts-ui
   

   Start the container and view the initialization logs:

   # GPU version
   docker compose -f docker-compose.gpu.yaml up -d 
   
   # CPU version    
   docker compose -f docker-compose.cpu.yaml up -d
   
   docker compose logs -f --no-log-prefix
   

3. Access ChatTTS WebUI

   Once started on 0.0.0.0:9966, you can access the WebUI using the device's IP:9966. For example:

   • Local: http://127.0.0.1:9966
   • Server: http://192.168.1.100:9966

Updating

1. Get the latest code from the main branch:

   git checkout main
   git pull origin main
   

2. Stop the container and rebuild with the latest image:

   docker compose down
   
   # GPU version
   docker compose -f docker-compose.gpu.yaml up -d --build
   
   # CPU version
   docker compose -f docker-compose.cpu.yaml up -d --build
   
   docker compose logs -f --no-log-prefix
   

Deployment Notes

1. If your GPU VRAM is less than 4GB, CPU mode will be forced.

2. On Windows or Linux, if you have an NVIDIA card with >4GB VRAM but the software still uses CPU, try uninstalling and reinstalling Torch. Run pip uninstall -y torch torchaudio first, then reinstall the CUDA version: pip install torch==2.7.1 torchaudio==2.7.1 --index-url https://download.pytorch.org/whl/cu128. Ensure you have CUDA 12.8+ installed.

3. The software checks if ModelScope is accessible. If yes, it downloads the model from ModelScope; otherwise, it downloads from huggingface.co.

Obtaining Voices (Speakers)

Starting from version 0.92, fixed voices in .csv or .pt format are supported. Simply download and save them in the speaker folder inside the software directory.

.pt files can be downloaded from the demo link page of the ChatTTS_Speaker project (https://modelscope.cn/studios/ttwwwaa/ChatTTS_Speaker).

You can also visit http://ttslist.aiqbh.com/10000cn/ to listen to audio samples and copy the corresponding voice seed value into the "Custom Voice Value" text box.

Note: The same voice seed value may sound slightly different across different devices. Even on the same device, the tone or pitch of the same voice seed may vary slightly between generations.

Adjusting Environment Settings

Open the .env file with a text editor to modify the configuration:

WEB_ADDRESS=127.0.0.1:9966 # Modify the Web service address and port
compile=false 
device=default # Defaults to CUDA (if VRAM > 4GB) or MPS. You can manually set this to cpu, mps, or cuda

FAQ & Troubleshooting

Modifying the HTTP Address

The default address is http://127.0.0.1:9966. To change this, open the .env file in the project folder and change WEB_ADDRESS=127.0.0.1:9966 to your preferred IP and port (e.g., WEB_ADDRESS=192.168.0.10:9966 to allow local network access).
