Method and system for segmenting phonemes from voice signals
First Claim
1. A method for segmenting phonemes from voice signals, comprising:
- extracting peak information from input voice signals;
calculating peak statistics per each frame based on the extracted peak information;
determining maxima among the calculated peak statistics per each frame; and
determining a valley between the maxima as a boundary between phonemes to perform a phoneme segmentation.

Abstract
A method and a system for segmenting phonemes from voice signals. A method for accurately segmenting phonemes, in which a histogram showing a peak distribution corresponding to an order is formed by using a high order concept, and a boundary indicating a starting point and an ending point of each phoneme is determined by calculating a peak statistic based on the histogram. The phoneme segmentation method can remarkably reduce an amount of calculation, and has an advantage of being applied to sound signal systems which perform sound coding, sound recognition, sound synthesizing, sound reinforcement, etc.
