Source Code Installation and Deployment of index-tts on Windows 10/11

Starting from v3.68, the configuration interface for F5-TTS can also be used for F5-TTS/Spark-TTS/index-TTS/Dia-TTS. You just need to fill in the correct URL address (usually http://127.0.0.1:7860 for local machine) and select the corresponding service from the dropdown list.

First, Install Conda Software

1. Download Miniconda

   • Open your browser, enter this URL, and press Enter: https://www.anaconda.com/download/success#miniconda

   • Scroll down, find the "Miniconda" section, click the download link for Windows, or use this direct link: https://repo.anaconda.com/miniconda/Miniconda3-latest-Windows-x86_64.exe

   • The file will be saved to your "Downloads" folder (e.g., C:\Users\YourUsername\Downloads), with a filename like Miniconda3-latest-Windows-x86_64.exe.

2. Install Miniconda

   • Double-click the downloaded file to open the installation window.

   • Click "Next", agree to the license agreement (click "I Agree").

   • Important: On the "Advanced Options" page, check Add Miniconda3 to my PATH environment variable. This allows you to use the conda command directly. Otherwise, you will encounter the error conda is not recognized as an internal or external command, operable program or batch file.

   • Note: Some systems might warn against adding it to PATH. Ignore the warning and check the box. This is a common pitfall for beginners; if you don't check it, you won't be able to use the commands later.

*   Click "Install", wait a few minutes, and then click "Finish" when done.
