Kind Code:
A1
Abstract:
A method for calculating the number of syllables in a unit time and a related apparatus. The method comprises: obtaining a first audio segment comprising human voice and background music, and separating the human voice from the first audio segment to obtain a second audio segment comprising only human voice; inputting the second audio segment into a trained neural network model for processing, and outputting a first feature vector, the trained neural network model being used for extracting the feature vector of the audio segment of the human voice (101); determining, on the basis of the first feature vector, a target number of syllables corresponding to the second audio segment, and determining a target singing time corresponding to the second audio segment (102); and determining, on the basis of the target number of syllables and the target singing time, the number of syllables in a target unit time corresponding to the second audio segment (103). The number of syllables in the unit time of a song without lyric text can be calculated.
