PROBLEM TO BE SOLVED: To attain improvement in the accuracy of input voice recognition by discriminating characters expressed by a voice input device from the class of received push button(PB) signals and how many times these PB signals are intermitted and specifying word candidates used for recognizing the input voice based on the discriminated result. SOLUTION: A PB recognition unit 30 of a voice recognizing device 1, which enables interactive voice communication with portable telephone radio equipment 2, discriminates the characters expressed by the portable telephone radio equipment 2 by discriminating the class of PB signals among signals received from an interface unit 10 and how many times these PB signals are intermitted. Namely, the received PB signals are converted to digital signals by a PB input part 31, and a PB recognizing part 32 which PB the converted digital signals belong to. Then, a PB counting part 33 counts how many times that PB is pressed, a character discriminating part 34 discriminates which character is displayed on a display on the side of the portable telephone radio equipment 2, and the discriminated result is preserved in a word selecting part 25. |
