PROBLEM TO BE SOLVED: To allow an unaccustomed user to easily use a speech recognition device by informing the user of contents of a predetermined guide when there is no speech input even if a predetermined time has passed from a point in time when a speech input period is specified to start. SOLUTION: Having informed of contents A of a guide, a control part 38 judges whether or not a push-to-talk(PTT) switch 36 is turned on, and following this, it judges whether it is a click operation. When it judges that it is not a click operation, it judges whether there is a speech input. When there is no speech input, the control part judges whether PTT switch 36 has been turned off, and if it remains being turned on, it is judged whether a predetermined time Ta has passed. And, if the predetermined time Ta has passed, the contents C of the guide are informed. Concrete contents of the contents C of this guide are 'Please, start with a prefecture name when you input your destination'. Thus, a user, who wants to set a destination, is informed of an input method. |
