In addition, the above-described sensor unit is composed of an ambient noise measurement sensor for measuring the ambient noise level of the mobile phone terminal device. The noise level transmitted from the sensor unit determines whether the voice recognition level is impossible, that is, the voice dialing level due to the ambient noise level. For example, when it is determined that noise of 45 dB or more occurs, the voice dialing mode is automatically released and the button dialing mode is automatically switched.

As a result, by providing a method for automatically switching a dialing mode according to the ambient noise level to a conventional mobile phone terminal device having a built-in voice recognition function, if the ambient noise level is a level where voice recognition is impossible, the voice dialing mode of the mobile phone terminal device is changed to the button dialing mode. By switching automatically, it realizes the function which can prevent unnecessary repetitive input of voice due to voice misrecognition.

For example, when the user operates the selection switch 201 for restraining the user's voice using the key input module 101, the selection switch 201 is connected to the signal line of the microphone 105. In step S303, the system control unit 119 of the mobile communication terminal determines whether a call is in progress. When not in a call, the system controller 119 maintains a communication standby state of the mobile communication terminal. On the other hand, if it is determined that the system controller 119 is currently in a call, the process proceeds to step S305.

At this time, the selection switch 201 is connected to the signal detection unit 203, the user's voice signal input to the microphone 105, to detect the user's voice signal. The signal detector 203 detects a signal level or frequency with respect to the voice signal. In step S307, the signal detector 203 determines whether the signal level for the voice signal exceeds the reference value or the frequency for the voice signal exceeds the reference value.

As a result of the determination, when the voice signal does not exceed the reference value, that is, when the user's call voice is appropriate, the process returns to step S305.

Therefore, the caller voice signal and the analog sound signal output through the caller control unit 207 overlap each other and are output to the speaker 107. In step S313, the emotional control unit 209 feeds back to the step S303 after a predetermined time has elapsed so that the function of the present invention can be exhibited only in a call state.

Here, the sound information is a ballad-like sound, to suppress the emotion of the user in a high-call state, the sound information may be a predetermined announcement if necessary. The announcement is a warning about a high-level call, a message indicating that the tone should be lowered. Therefore, the elapse of a predetermined time in the step S313 represents the output time for the sound information or the output time for the announcement. As a result, when a voice call is triggered in the voice call process, the user can control the voice call by listening to predetermined sound information to the user.
