Abstract:
1. A method for segmenting phonemes from voice signals, comprising: extracting peak information from input voice signals, the peak information including first peak information corresponding to a plurality of first order peaks of the input voice signals and second peak information corresponding to a plurality of second order peaks for the plurality of first order peaks; determining a length of a frame for calculating peak statistics; forming a histogram showing a density distribution of the second order peaks with respect to the determined frame length; calculating the peak statistics using the histogram; determining two neighboring maxima of the histogram using the calculated peak statistics per each frame; and determining a valley between the two neighboring maxima as a boundary between phonemes to perform a phoneme segmentation; wherein the method further comprises: extracting the peak information from voice signals on a time domain; defining a peak order with respect to the extracted peak information; comparing a peak measurement value of the defined peak order with a predetermined critical peak measurement value; and determining a present peak order as a final peak order, which is used to extract the second peak information, when the peak measurement value is greater than the critical peak measurement value.
