How to create subtitles from speech on iPhone.
This tool generates a subtitle document. Burning that text into video is a separate Pro workflow, so you can review the words before changing any frames.
Recognize and edit
Allow speech-recognition access, run Apple Speech, and correct names, punctuation, or misunderstood words in the result.
Export or embed
Save the subtitle file, or use the dedicated Embed in Video action to continue into Burn In Subtitles.
Choose the output for the next job
SRT and ASS preserve timed cues for caption workflows; TXT is useful when you mainly need readable transcript text. Recognition is only a first draft: background noise, names, accents, and specialist vocabulary can require corrections.
Speech to Subtitles uses Apple Speech and requires system speech-recognition permission. Availability and quality depend on the selected language, device, Apple system services, and current network environment, so it should not be treated as guaranteed offline processing.
