摘要： A method comprising: receiving an utterance, an original pitch contour of the utterance, and a target pitch contour for the utterance, wherein the utterance comprises a plurality of consecutive frames, and wherein at least one of said frames is a voiced frame; calculating an original intensity contour of said utterance; generating a pitch modified utterance based on the target pitch contour; calculating an intensity modification factor for each of said frames, based on said original pitch contour and on said target pitch contour, to produce a sequence of intensity modification factors corresponding to said plurality of consecutive frames; calculating a final intensity contour for said utterance by applying said intensity modification factors to said original intensity contour; and generating a coherently modified speech signal by time dependent scaling of the intensity of said pitch modified utterance according to said final intensity contour.

摘要： A voice signal processing apparatus and a voice signal processing method are provided. A first sampling point of an mth original frequency-lowered signal frame phase-matched to the sampling point corresponding to a phase reference sampling point number is determined according to the phase reference sampling point number of an (m−1)th original frequency-lowered signal frame corresponding to a middle sampling point of an (m−1)th renovating frequency-lowered signal frame. The q consecutive sampling points starting from the first sampling point are used as the sampling points of an mth renovating frequency-lowered signal frame.

摘要： In a wearable translation device, the control circuit obtains an audio signal of the second language, which has been converted from a first audio signal of the first language, and obtains a second audio signal of the first language reconverted from the audio signal of the second language. The first speaker device converts the audio signal of the second language into a first voice and outputs the first voice. The second speaker device converts the second audio signal of the first language into a second voice and outputs the second voice. The audio processing circuit executes such a process that the second voice from the second speaker device is directed toward an auditory part of a user, based on a position of the auditory part relative to the second speaker device.
