What you can create with Index TTS 2
Prepare a clean voice sample and a punctuated script. Speech output can supply narration for a script-to-video project; the voice tool itself returns audio rather than a finished video.
When to use this tool
Index TTS 2 suits an explainer voiceover, product narration or spoken passage when you have the script and a voice sample to guide delivery.
Provide one 1–30 second voice reference and the words to speak; this tool produces audio, with no video framing or visual sequence. Choose Script to Video to combine narration with footage and subtitles, or AI Music Video for a song-led project.
