摘要： PROBLEM TO BE SOLVED: To eliminate the need to re-set a threshold value according to the voice quality and speaking contents of a user at the time of recognition by judging the adequacy of a recognition result from neither the degree of similarity nor the difference. SOLUTION: A voice is inputted to a voice input device 101, inputted to a signal processor 102, and converted into a time series of feature quantities. An unrestricted similarity calculation device 104 combines models that a learning data holding device 103 holds and outputs a time series of models which is most similar to the time series of feature quantities outputted from the signal processor 102. A recognized word generating device 105 combines models of the holding device 103 according to a recognized word. A restricted similarity calculation device 106 outputs a time series of models constituting the recognized word which is most similar to the time series of the feature quantities outputted from the signal processor 102. An adequacy evaluation device 107 evaluates the adequacy of the recognized word through the unrestricted similarity calculation device 104 and the restricted similarity calculation device 106 and outputs the result as a recognition result.

摘要： PURPOSE:To simplify the constitution of the entire device and to reduce the number of arithmetic operations by beforehand computing weighting coefficient vectors and eliminating a weighting coefficient vector computing section. CONSTITUTION:The device is provided with a weighting coefficient vector storage means so as to store weighting coefficient vectors prior to the learning of a Hidden Markov Model(HMM) and to use their fixed values during a pattern recognition. Namely, a weighting vector storage section 104 stores weighting coefficients u1, u2,... UK corresponding to a first to a Kth representative vectors as fixed values independent to the frames of an input voice. Therefore, during an HMM learning, the computations of weighting coefficient vectors, which are computed sequentially, are eliminated while conducting a recognition, a voice recognition is performed by employing a smaller amount of a storage capacity, the device is simplified and the amount of computations is reduced.

摘要： PURPOSE:To recognize a highly accurate time sequence pattern by defining a linear forecasting model in each status and defining the cumulative probability of a forecasting error signal for an input pattern as the likelihood of the input pattern of the model. CONSTITUTION:The 1st parameter calculating part 507 finds out respective estimated values for transition probability gamma1 in a status (i) and the variance/ covariance SIGMA1 of forecasted errors by calculating the ratios of the numerators and denominators of respective parameters calculated by the 1st and 2nd accumulated sum calculating parts 506, 512. The 2nd parameter calculating part 515 finds out the estimated value of a forecasted coefficient a1 in the status (i) from various values calculated by the 3rd accumulated sum calculating part 514. The estimated value is stored in a parameter storage part 508 and a total likelihood calculating part 509 finds out the sum of (r) in the likelihood P(X ¦lambda) from the stored parameter estimated value. Consequently, the feature of a change in each feature vector with the lapse of time can be properly expressed.
