Abstract： |
The voice speed adaptive voice identifying system capable of being in-situ used, without needing voice speed measurement in advance and with less increased calculation amount includes voice acquisition device, front end processing module, characteristic extracting module, tone identifying module, training module, acoustic layer identifying module, pinyin grammar understanding module and phonetic understanding module. The training module has the training parameters including average segment length, variance and correlation coefficient of connected two voice units; and the acoustic layer identifying module calculates segment length probability. During calculating segment length probability, the segment length probability may be dynamically regulated in real time by means of the segment length probability weighting module and voice speed a voice tone regulating module to raise system performance and decrease the insertion error and deletion error of the system. |
