LyricManager

Aligning lyrics to audio is the task of determining the precise time in a song when each individual word is being sung, i.e. the start and end time of every lyric. In the past, this timing information had to be manually annotated. Thanks to advances in machine learning, a computer is now able to automatically provide accurate timing annotations for a wide variety of audio and lyrics.

AutoLyrixAlign is a system published in 2019 which embody these advancements. Given an audio file and a text file containing associated lyrics, AutoLyrixAlign provides timing information for each word in a complete set of lyrics. Aside from this core feature, AutoLyrixAlign is feature sparse. It is executed via Command-Line and only

Connecting audio and video

Automatically aligning lyrics to audio, while impressive, is not going to interest audiences on its own. A system is needed to create captivating visuals based on the lyric timing information. PlanMixPlay natively supports the JSON output that LyricManager generates.

The PlanMixPlay project page offers further details on the importance of synchronizing visuals to audio. A significant benefit of the emergence of automatic aligning is that any song featuring lyrics can now have impressive custom song-specific visuals generated to accompany it.
