SAPI

For Windows 7 and above, you can add the text-to-speech package for a language in the system's language settings to use it.

Natural Voice

On Windows 10 and Windows 11, you can use Windows Natural Voice.

WARNING

Due to Microsoft's changes in the encryption method for newer version language packs, the language packs installed in the system and the downloaded newer version language packs cannot be used directly. Please refer to this article for usage instructions.

On Windows 11, in addition to the language's speech synthesis package, you can also add higher-quality natural voices via Accessibility -> Narrator -> Add natural voices.

On Windows 10, or if you don't want to add it to the system, you can download Microsoft Natural Voice from NVDA Chinese Website and extract it to the software directory to use natural voices.

On Windows 10, the necessary runtime and recognition models are missing in the system; or the Windows 11 version is too low, and the built-in runtime version is outdated. In addition to downloading the voice package, you also need to download the Natural Voice Runtime and extract it to the software directory.
