  In S104, the call mode detecting unit 152 detects whether the user has selected the normal mode or the hands-free mode as the call mode. When the normal mode is selected by pressing the operation key 111, the process proceeds to S105. On the other hand, when the hands-free mode is selected due to the command input by the voice “answer the phone”, the process proceeds to S107.

In S105, the mobile phone control unit 151 selects and executes the normal mode as the call mode.
In S106, the mobile phone control unit 151 performs various settings necessary for a call in the normal mode, such as setting the volume of the normal mode speaker 122 to a setting value by the user.
In S107, a call in the normal mode is started.

In S108, the voice recognition unit 154 continues the voice recognition.
In S109, the mobile phone control unit 151 selects and executes the hands-free mode as the call mode.

  In S110, the mobile phone control unit 151 performs various settings necessary for the call in the hands-free mode, such as setting the voice output destination to the hands-free speaker 132 and setting the volume of the hands-free speaker 132 to a high volume.

In S111, a call is started in the hands-free mode.
In S112, the call is terminated. Here, in both the normal mode and the hands-free mode, when the end key 111b is pressed, the call is ended. Further, in the hands-free mode, it can be set to end when a voice “hang up” is recognized.

  As described above, according to the present embodiment, when there is an incoming call, it is possible to answer the phone without using a hand. Further, if the voice “hang up” is recognized, the mobile phone terminal 100 can be used without using any hand from the incoming call response to the end of the call. Furthermore, since the hands-free microphone 131 and the hands-free speaker 132 are provided with directivity, the accuracy of voice recognition is improved and the secrecy can be improved. Furthermore, since the hands-free microphone 131 can suppress the noise component, it can recognize the user's voice more accurately and can make a call with clearer voice. As described above, the mobile phone terminal 100 according to the present embodiment can be performed from the incoming call to the end of the call in a hands-free manner. Therefore, the mobile phone terminal 100 is useful for a handicapped person with a handicap. In addition, since the mobile phone terminal 100 authenticates that it is attached to the holder 500 and the authentication is not performed correctly, the mobile phone terminal 100 is forced to enter the normal mode. The hands-free mode can be executed while being held in a state suitable for.
