PURPOSE:To obtain an accurate and reliable recognition result. CONSTITUTION:A feature parameter extraction part 2 extracts a feature parameter from an input voice from a voice input part 1. Standard parameters of registered voices are registered in a dictionary 3 and a recognition part 4 finds the similarity of the extracted feature parameter to the standard parameters, parameter by parameter. Then the similarity of each parameter is weighted while the characteristic of reliability regarding the similarity or nonsimilarity of the parameter is reflected to calculate the total similarity or nonsimilarity between the input voice and registered voice, thereby recognizing the input voice according to the similarity or nonsimilarity. |
