Transcription for Subtitles, Notes, and Voiceover Scripts
VoiceIndex AI uses transcription as part of a larger publishing workflow: convert audio or video into editable text, export subtitles, clean up notes, then continue into editing or AI voiceover production.
Why use a subtitle-first workflow
Long recordings and MP4 clips need file upload, timestamp preservation, export formats, and review tools. A dedicated workflow reduces the time between raw media, usable captions, and publishable scripts.
- Make subtitles: send MP4 clips to Video to SRT when the next step is caption export.
- Use the guides: compare workflows in the MP4 to SRT guide and recording to text guide.
- Create voiceover: move cleaned scripts into text to speech, the YouTube voiceover generator, the TikTok voiceover generator, or the AI voice library for narration.
