    Abstract: A speech recognition system includes an acoustic analyzer which produces a time sequence of acoustic parameters from an input speech signal in an utterance boundary thereof, and estimates a trajectory in a parameter space from the time sequence of acoustic parameters. The trajectory is re-sampled in the parameter space at predetermined constant intervals sequentially each time the acoustic parameters are produced by the acoustic analyzing means, thereby producing an input utterance pattern. The input utterance pattern is matched with reference speech patterns to recognize the input speech signal. The speech recognition system also has an utterance boundary detector for detecting the utterance boundary of the input speech signal. The trajectory is re-sampled while the utterance boundary is being detected by the utterance boundary detector.

    Abstract: Apparatus for obtaining an orthogonal transformer for use in signal analysis. This apparatus is especially useful in cepstral analysis where vocal tract characteristics of a signal are separated from a sound source. A buffer memory 10 temporarily stores input time series data and an orthogonal transformation is carried out by an orthogonal transform means 20 by multiplying each predetermined data read sequentially out of the buffer memory 10 by a predetermined twiddle factor. A controller 30 is used to specify the data read out of the buffer memory 10 and for giving the twiddle factor a value of 1 and r/2.sup.l corresponding to the magnitude of the real and imaginary part of the twiddle factor. Cepstrum information is obtainable using simple hardware to analyze the data generated by the orthogonal transformer.

    Abstract: A start point vicinity of an uttered input speech pattern is set. DP-matching is performed between the input speech pattern and a plurality of reference patterns obtained by connecting previously prepared reference patterns in the start point vicinity of a portion for the head word of the input speech pattern. A point within the start point vicinity is determined as a temporary start point. The dissimilarity proportional to the time length of the reference pattern is calculated and then converted into a value proportional to the time length of the input pattern from the temporary start point. The dissimilarity measure between the input speech pattern and the reference pattern on the second and the following digits are determined as a value proportional to the time length of the input speech pattern. The end time point of the input speech pattern is determined on the basis of the minimum value of a normalized dissimilarity measure and by the time length of the input speech pattern.
