<p>PURPOSE: To improve the accuracy of recognition by reproducing an input voice in a detected voice section, and only at the time of inputting information indicating the correct detection of the voice section, registering the input voice in a dictionary. CONSTITUTION: A voice section detection part 2 executes prescribed threshold processing for an input voice to detect it. A voice section storing part 4 selectively extracts only a voice in the voice section based upon the detected voice section information and applies the extracted voice to a voice reproducing part 5 to output the voice. When information indicating that the detection of the voice section is correct is specified and inputted from a correct/error state input part 6, a recognition dictionary memory 7 registers an input voice pattern detected by an acoustic analysis part 8 as a dictionary pattern. At the time of recognizing a voice after registering the pattern in the memory 7, the detection part 2 detects an input voice inputted through a voice input part 1 and a voice recognition part 9 calculates and compares the degree of similarity between the voice pattern found out by the analysis part 8 and the dictionary pattern registered in the memory 7. Consequently the accuracy of recognition can be improved.</p> |
