PROBLEM TO BE SOLVED: To provide a speech recognition device, a speech recognition subject section setting method, and a speech recognition section setting program that improve response.SOLUTION: An acoustic analysis unit 3 removes the reproduction sound of a voice guidance from the acquired sound of sound acquisition means that acquires the sound data of the voice guidance during a reproduction section and thereafter, and determines, on the basis of the sound data after the reproduction sound of the voice guidance is removed, whether or not an intension to request speech recognition exists in a user uttered sound, without performing speech recognition processing on the user uttered sound included in the acquired sound. When it is determined that the intension to request speech recognition exists, the acoustic analysis unit 3 makes the reproduction section of the voice guidance included as a speech recognition subject section; conversely, when it is determined that the intension to request speech recognition does not exist, the acoustic analysis unit 3 sets the reproduction section of the voice guidance not to be included in the speech recognition subject section.SELECTED DRAWING: Figure 1 |
