Providing shorter uniform frame lengths in dynamic time warping for voice conversion

摘要

A method and apparatus for frame matching is disclosed. The frame matching includes receiving numbers of frames in first and second input signals within a voice unit. A uniform frame length of the first input signal is then updated to a time sample period of the first input signal divided by the number of frames in the second input signal, when the number of frames in the second input signal is greater than or equal to the number of frames in the first input signal. Otherwise, a uniform frame length of the second input signal is updated to a time sample period of the second input signal divided by the number of frames in the first input signal.
