PROBLEM TO BE SOLVED: To provide a voice recognizing device with higher performance. SOLUTION: A voice input part 101 inputs the voice that a user utters through a microphone, etc., performs A/D conversion for the inputted voice, and outputs a digital voice signal. Then an analysis and recognition part 102 inputs the voice signal obtained from the voice input part 101 and takes an acoustic analysis to calculate feature parameters of the input voice such as voice power and an LPC coefficient. According to the calculated feature parameters, voice recognition based upon the input voice signal is carried out to output a plurality of candidates for a recognition result. A storage part 103, on the other hand, stores a history of past inputted character strings and a candidate decision part 104 determines a more proper final candidate or candidate order according to the plurality of candidates obtained from the analysis and recognition part 102 and the contents of the storage part 103. |
