Index-TTS Windows One-Click Installer
If you want to experience the powerful AI speech synthesis technology Index-TTS, open-sourced by Bilibili, but are frustrated by the complex and error-prone installation process, then this one-click installer is tailor-made for you.
With this package, you can easily run Index-TTS on Windows 10 or Windows 11 without worrying about any technical details, especially the installation nightmare of the pynini library, which is a major deterrent for Windows users.
❓ What Exactly is Index-TTS?
Index-TTS is a highly advanced text-to-speech (TTS) model open-sourced by the Bilibili (B-station) team, extensively optimized for the Chinese language. Its goal is to generate natural, expressive speech that rivals human voice quality.
Its core advantages are outstanding:
- Extremely Accurate Pronunciation: It offers precise control when handling Chinese characters with multiple pronunciations (polyphones). You can directly specify the pronunciation of a character like “行” in “银行 (yín háng)” using pinyin, significantly reducing the chances of embarrassing AI mispronunciations.
- Highly Natural Pausing: It intelligently understands punctuation and generates pauses of varying lengths accordingly, making long passages sound rhythmic and natural, just like a real person speaking.
- Voice Cloning (Zero-Shot TTS): By providing just a short, clear audio sample of a target voice (like your own), it can "clone" that timbre and use it to read any text you input.
- Superior Performance: In various technical benchmarks, the quality and naturalness of the speech synthesized by Index-TTS are at the forefront of the industry, even surpassing many other well-known models.
However, behind these powerful features lies a complex installation and deployment process. The official installation method requires users to be proficient with the command line, manually configure a Python environment, and resolve various dependency conflicts—especially the notoriously difficult compilation and installation of the pynini library on Windows.
The value of this one-click installer is that it eliminates all these technical hurdles for you!

What Happens After Double-Clicking?

Auto-Checks and Downloads Models: The first thing the script does is check if the required model files (several GB in size) are complete. If any files are missing, it will automatically start downloading them from the server. You will see a "Downloading..." progress indicator in the window. This process will take some time, depending on your internet speed, so please be patient.
Starts the Core Service: Once all the model files are ready, the script will automatically launch the core WebUI service for Index-TTS. This is the user interface you will use for speech synthesis.
Waits for the Success Message: Continue to wait patiently until you see the following key message in the black window:
