2. Description of the Related Art When an information service or the like is performed using a telephone, it is usually necessary to select the information content according to the voice guidance on the called side. Generally, DTMF (Du
AlTone Muli Frequency) signals are often used for selection, but it becomes more convenient if the user can select information contents by voice. In the case of a system that can be selected by voice, a telephone voice recognition device is usually provided on the called side, and this is realized by recognizing the utterance of the caller.

For example, Japanese Unexamined Patent Publication No. 11-355445 discloses a recognition device for switching to a dictionary corresponding to the calling telephone number of the other party. Also, Japanese Patent Laid-Open No. 2000-125
Japanese Laid-Open Patent Publication No. 006 discloses a recognition device which judges whether the line of the other party is a general public line or a mobile phone from the calling telephone number of the other party and selects a dictionary suitable for the line. However, a telephone voice recognition device is not generally prepared on the receiving side, and if there is no telephone voice recognition device on the receiving side, selection by voice is impossible, and conventionally, control using a DTMF signal is performed. I had to do.

On the other hand, in many cases, a voice dialing function is added to a calling telephone used by a user. For example, a technique represented by a voice dialing device disclosed in Japanese Examined Patent Publication No. 2-29265 is a technique for calling a corresponding telephone number when a user utters a voice of a caller to recognize the voice.
