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

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

1. Install Conda

1. Download Miniconda

   • Open your web browser and go to: https://www.anaconda.com/download/success#miniconda

   • Scroll down to the "Miniconda" section and click the Windows download link, 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 name like Miniconda3-latest-Windows-x86_64.exe.

2. Install Miniconda

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

   • Click "Next" and agree to the license agreement ("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 computers might warn against adding it to PATH, but ignore the warning and check the box. This is a common pitfall for beginners. Without this, the commands won't work later.

• Click "Install" and wait for a few minutes. Click "Finish" when done.
