Description

CLIP2 is a dataset for lyric intelligibility prediction in music. It is used in the Second Cadenza Lyric Intelligibility Prediction Challenge.

Understanding the lyrics in music is key for music enjoyment [1]. People with hearing loss can have difficulty clearly and effortlessly hearing lyrics, however [2]. In speech technology, having metrics to automatically evaluate intelligibility has driven improvements in speech enhancement. We want to do the same for music with lyrics!

A detailed description of the challenge can be found on our website
