Despite its lightweight requirements, the results are shockingly good. We start by walking through the local installation process, followed by a quick demo of the built-in WebUI. Once everything is running, we test the voice cloning feature, which outputs extremely fast and highly accurate speech synthesis—even with just one voice sample. Next, we test its ability to translate an English voice clone into Chinese, and the results are surprisingly fluid and natural. We wrap up with a quick test in another language and confirm that IndexTTS currently supports only English and Chinese, before closing out with some final thoughts on its performance and future potential.
