Abstract
PURPOSE:To recognize a voice corresponding to an optical signal sequence efficiently by providing a candidate selecting means which outputs a signal sequence of candidates from a hypothesis table as a voice recognition result. CONSTITUTION:The hypothesis table 21 contains hypotheses consisting of the symbol sequence of an input voice and the end time of a voice section, a hypothesis selecting means 22 selects the hypothesis of the end time, and a hypothesis generating means 23 couples a specific signal with the signal sequence to generate a symbol sequence of the new hypothesis. A model generating means 3 generates a voice model represented by the symbol sequence depending upon the symbol sequence and the phoneme context obtained from the features of the input voice. A hypothesis registration means 41 compares the voice model with the features of the input voice to detect the end time when the likelihood becomes maximum and generates and registers a new hypothesis in the hypothesis table 21. A candidate registering means 5 selects the symbol sequence of candidates and outputs it as the voice recognition result. Consequently, the number of hypotheses which are generated is decreased and a voice corresponding to the optional symbol sequence can be recognized efficiently.

段とを備えたことを特徴とする音声認識装置。A hypothesis table that holds a hypothesis consisting of a symbol sequence of an input voice and an end time of a speech interval; a hypothesis selection means for selecting a hypothesis of an end time from this hypothesis table; A hypothesis generating means that combines predetermined symbols to generate a new hypothetical symbol sequence, and a speech model represented by the symbol sequence generated by this hypothesis generating means depends on the phoneme context obtained from the symbol sequence and the characteristics of the input speech. A model generation means that generates a model by comparing the voice model generated by this model generation means with the characteristics of the input voice, detects the end time of the voice section where the likelihood is maximum, and generates a new hypothesis based on this end time. A speech recognition device comprising: hypothesis registration means for registering the selected symbol sequence in the hypothesis table; and candidate selection means for selecting a candidate symbol sequence from the hypothesis table and outputting it as a speech recognition result.
