Phoneme boundary detection apparatus and speech recognition apparatus

摘要

PROBLEM TO BE SOLVED: To detect a phonemic boundary with high accuracy at high speed by generating plural parameters at the time delayed backwards by a prescribed unit time to plural parameters outputted from a first input neuron group and outputting them to an intermediate layer. ;SOLUTION: A delay element 54 delays ten parameters outputted from an intermediate neuron group 53 by a prescribed unit time and outputs them to an intermediate neuron group 52. In an output latch 55, they become a state neuron group in the forward module B(t-1) having ten units b₁-b₁₀, an output value outputted from the intermediate neuron group 53 at the time t-1 being the time of completion of operation of the forward module B(t-1) is transiently stored and outputted to a hidden neuron group D of a neural network at the right side for detecting the boundary of sound element. By using this network, the boundary of sound element is detected with high accuracy and at high speed.;COPYRIGHT: (C)1998,JPO
