(Song and Lyric Retrieval System: This system provides two retrieval methods based on humming or lyric. According to the inputted humming, tune is extracted for retrieving the matched song in the music lib. Users could start humming at any epoch of a song; and both with and without lyric could make it an effective search. In the lyric retrieval method, users only need to speak one or several lyrics, then it gets the name of the demanded song automatically for the users.)
