DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a portable communication terminal, and more particularly, to a portable communication terminal with a voice notification function capable of notifying a communication partner of information such as a telephone number by voice.

[0002]

2. Description of the Related Art In recent years, the spread of mobile phones has been remarkable.
Each manufacturer is trying to differentiate products by adding more operable functions. As an example, if the telephone number of the other party is registered in the telephone before making a call, it is very convenient because the trouble of checking the telephone number can be omitted. For this reason, most mobile phones are now provided with a telephone number registration function that can register telephone numbers and the like.

[0003] Further, as a prior art for preventing erroneous dialing at the time of calling and improving operability at the time of calling by outputting a dial number by voice at the time of calling, for example, Japanese Patent Publication No. 58-37750 is disclosed. , Tokiko Sho 61-38900
JP-A-3-80654 or JP-A-7-80654.
No. 95280.

[0004] On the other hand, with the spread of mobile phones, various problems have arisen. In recent years, in particular, calls in public places lack consideration for people around them, and usage restrictions are imposed in some places. Even in places where usage is not regulated, mobile phones are often harder to hear than the other parties, and in such cases the voice naturally becomes louder and often disturbs other people .

[0005] Further, by the telephone number registration function described above,
When transmitting the telephone number registered in the mobile phone to the other party, the desired telephone number is called from the memory and displayed on the display of the mobile phone, and the telephone number is transmitted to the other party while watching this display. . Therefore, since the position of the mouth of the mobile phone and the position of the mouth are inevitably separated, the voice naturally becomes loud, and there is a problem in that it inconveniences surrounding people. Further, there is also a problem that the telephone number cannot be transmitted to the other party when the telephone number is not desired to be known to the surrounding people.

In order to solve such a problem, Japanese Patent Laid-Open Publication No. Sho 59-28308, for example, discloses a function of transmitting a voice signal corresponding to a dial operation, so that a telephone number can be obtained without being known to surrounding people. There is disclosed a conventional technology provided with a confidential talk function of transmission capable of notifying the other party of the transmission. That is, according to this conventional technique, a telephone number is transmitted to the other party during a call without converting the dial pressed by the operator into a voice signal, so that the dial is not known to the surroundings and does not bother others. It becomes possible. Further, according to this conventional technique, the operator can hear the dial pressed by the operator by voice, so that the operator can judge whether the telephone number has been mistakenly pressed.

[0007]

However, Japanese Unexamined Patent Publication No.
In the prior art disclosed in Japanese Patent Application Laid-Open No. 9-28308, when a telephone number is transmitted to a communication partner, a dial operation must be performed by the number corresponding to the telephone number, and there is a problem that operability is poor. Further, in this conventional technique, there is a possibility that a telephone number may be mistakenly pressed, for example, in such a case. In such a case, it is not only difficult to give an accurate telephone number to the other party, but also it is necessary to correct and operate again. If that happens, it takes a lot of time to tell the other party. Also, a telephone number is usually a group of seven or more digits,
The greater the number of digits in the telephone number, the greater the probability of mistaking the telephone number. For this reason, such a conventional technique has a problem that the burden on the operator is large.

The present invention solves the above-mentioned problems of the prior art, and eliminates the need to perform dial operations by the number corresponding to the telephone number and prevents the telephone number from being erroneously pressed halfway. It is an object of the present invention to provide a mobile communication terminal having a voice notification function provided with the above.

[0009]
