Operating Instructions

Below are the general steps for ChatTTS (exact steps may vary by version and platform):

1. environmental preparation::

   • Ensure that the Python 3.9+ environment is installed on your computer and that the necessary libraries such as Git, libsndfile and ffmpeg are installed.
   • Clone the ChatTTS source repository using Git.

2. Project Settings::

   • Create a virtual environment using Python's venv module and activate it.
   • Install dependent libraries required by ChatTTS, such as torch and torchaudio.

3. Initiation of projects::

   • Run the startup command in the project directory, e.g.python app.py(Specific commands may vary depending on the structure of the project).
   • Upon startup, the browser will automatically open and display the ChatTTS web interface.

4. text-to-speech::

   • Enter the text you want to convert to speech in the Web interface.
   • Adjust parameters such as speech rate, volume, and timbre as needed.
   • Click on "Generate Speech" or a similar button and ChatTTS will start converting text to speech.
   • After the conversion is complete, you can play the generated voice directly or download it to save it locally.

In addition, ChatTTS also supports calling via API interface, which is convenient for developers to integrate it into other applications. Developers can choose the appropriate calling method and parameter settings according to their needs.
