Automatic speech alignment
What this task is
Timing subtitles so each line appears and disappears exactly in step with the speech, while keeping line length and on-screen duration comfortable to read.
How AI replaces it
From 2017, automatic speech alignment matched subtitle text to the audio track and generated frame-accurate timecodes. By 2023 subtitle timing was largely done automatically by software.
What stays human
People only fine-tune tricky passages such as rapid or overlapping dialogue and scene cuts, and watch the result to check the overall viewing experience.
