Techniques for identifying and correcting synchronization errors for a media file are described herein. A first file that includes a first set of words comprising lyrics of a media file may be maintained. One or more portions of the media file that represent vocal audio may be separated from other portions of the media file that represent instrumental audio by a computer system. A second file may be generated based at least in part on using an automated speech recognition on the separated one or more portions of the media file. The second file my include time stamps for a second set of words comprising the lyrics in the separated one or more portions of the media file. The first file may be modified with an offset time value that is determined by aligning the first set of words with the second set of words.

Lyrics synchronization

A computing device can periodically acquire a current track time for a media content item being played. The device can periodically compare the current track time with a respective start time and a respective end time for each line (or segment) in a plurality of lines of text (or segments of text) associated with the media content item. If the device determines that the current track time is between start and end times for a given line of text, then the device can display the given line of text. A user of the device can scroll through the lines of text associated with the media content item. If the user selects a particular line of text, the device can identify a start time for the selected line of text. The device can then play the media content item at the identified start time of the selected line of text.
