Abstract
A method and system for converting a source voice to a target voice is disclosed. The method comprises: recording source voice data and target voice data; extracting spectral envelope features from the source voice data and target voice data; time-aligning pairs of frames based on the extracted spectral envelope features; converting each pair of frames into a frequency domain; generating a plurality of frequency-warping factor candidates, wherein each of the plurality of frequency-warping factor candidates is associated with one of the pairs of frames; generating a single global frequency-warping factor based on the candidates; acquiring source speech; converting the source speech to target speech based on the global frequency-warping factor; generating a waveform comprising the target speech; and playing the waveform comprising the target speech to a user.
