2021:Automatic Lyrics Transcription
This year we host the MIREX2021: Automatic Lyrics Transcription challenge. You are free to participate in one of the tasks or both of them.
The task of Lyrics Transcription aims to identify the words from sung utterances, in the same way as in automatic speech recognition. This can be mathematically expressed as follows:
Prediction(w) = argmax P(w|X)
where w and X are the word and acoustic features respectively.
Ideally, the lyrics transcriber should return meaningful word sequences:
Prediction(w) = [ <w_1>, <w_2>, ..., <w_N> ]
The algorithm receives either monophonic singing performances or a polyphonic mix (singing voice + musical accompaniment). Both cases are evaluated separately in this challenge.
