INDIVIDUAL STUDY PROCESS SYSTEM FOR AURAL CONFIRMATION

摘要

PURPOSE:To attain a high aural confirmation rate and thus to increase the using efficiency be drawing out the standard pattern of each phoneme from part of the study sample. CONSTITUTION:When the new speaker unused for the calculation of the conversion formula pronounces part of the study words to be recognized, the average corelation coefficient is calculated between various phonemes and their words based on the aural waves. The value obtained through the above calculation is then converted into the logarithm cross-sectional area ratio. Using the value of the area ratio and the conversion formula, the value equivalent to the logarithm cross-sectional area ratioconverted from the averaged correlation coefficient for all words to be recognized is calculated for both the phoneme contained in the study word and the phoneme which is not contained. In this way, the standard pattern based on each phoneme is produced in accordance with the individual difference.
