Description

Description: TECHNICAL FIELD The present invention relates to a voice dialing device, and more particularly, to a voice dialing device for automatically dialing by uttering the name of a telephone subscriber corresponding to a dialed number. It is.

2. Description of the Related Art A conventional telephone dialing device needs to input the dial number of the other party's telephone subscriber by manual dialing when making a call. This type of dial device has a heavy burden on the user, such as storing the dialed number of the other party when making a call or referring to the dialed number of the other party with a memo or the like. Therefore, a method of automatically outputting a dial signal by voice input instead of a manual dial operation has been proposed (JP-A-61-144157). According to this method, it is not necessary for the user to memorize the dialed number or perform a dial operation while looking at a memo or the like. In this type of device, a user must register a standard pattern for voice recognition and a dial number corresponding to the standard pattern in advance. After calling a person who has not been registered as a voice by manual dialing, if the user wants to register this person, he or she must enter the dial number again by key input and register the corresponding voice.
This means that if you register before dialing, you can dial by voice input, but you may want to register the other party after the call ends, such as when you have no time to register due to urgency . In this case, it is necessary to re-enter the dial number by keying in the registration, which places a burden on the user.

In the above-described device, as described above,
It is necessary for the user to register in advance the standard pattern for voice recognition and voice response and the corresponding dial number. When registering the dial number in the city where the telephone is installed, Usually does not include the area code, but this means that when the location of the telephone moves, for example, when you move from Tokyo to Yokohama, you will call a Tokyo acquaintance already registered from Yokohama. If you want to dial, if you send a dial number that has already been registered, the area code of Tokyo will not be sent, and no dial call will be made to the intended party. Conversely, if you want to make a call to an already registered Yokohama friend, the area code of Yokohama will be transmitted even though you are in the city.
