Of course, auto-sync is at its most efficient when a human being accurately transcribes all spoken dialog/narration in a video’s soundtrack, but the savings in time is still quite substantial. While this tutorial isn’t focused on how to use auto sync (watch a segment from Google’s launch of the YouTube auto-accessibility features for a tutorial of sorts), it is worth pointing out the primary benefit of auto-sync: it reduces (and in some cases-shorter videos with fewer unique speakers, for instance-eliminates) the need for the traditional painstaking synchronization process that consumes the most time of any portion of the captioning process. However, it is the auto-sync feature that figures to be-at least in the short term-a real game-changer for serious CIYers.
Most of the buzz surrounded the auto-caption feature based upon the speech-to-text engine that powers Google Voice, auto-caption allows individual viewers to access a machine-generated transcription of a video’s speech content, which is then automatically synchronized with the video’s sound track and displayed as individual captions. One of the most intriguing CIY-related developments in captioning has been Google’s automatic accessibility features for YouTube channels.
