  Specifically, the control unit 30 performs control to set one of a plurality of restriction modes as a restriction state that restricts execution of any one of a plurality of functions that can be executed by the mobile phone 1. The control unit 30 executes the specified function when the function specified by the voice recognition unit 60 is not limited in this restricted state. On the other hand, when the specified function is restricted, the control unit 30 does not execute the specified function, and the execution of the specified function and the specified function is restricted. Notification is given by the display unit 21.

  In addition, when the execution of the function specified by the voice recognition unit 60 is restricted in the restricted state, the control unit 30 has the current restricted state among a plurality of restricted modes whose functions are restricted from being executed. Which restriction mode is applicable is notified to the determination unit 70 and notified.

  In addition, the control unit 30 acquires a list indicating functions that are restricted or executable in the restricted state, or functions that can be executed by voice recognition, and causes the display unit 21 to display them. .

  Furthermore, when the execution of the function specified by the voice recognition unit 60 is restricted, the control unit 30 receives an input as to whether or not to release this restriction. Then, the control unit 30 executes the specified function when receiving an input to cancel, and does not execute the specified function when receiving an input not to cancel. Here, when the specified function is executed, the restricted state is temporarily released. However, as the execution of this function is finished, the control unit 30 changes the original restricted state to the same function. Restrict execution again.

  The communication unit 40 communicates with an external device (base station) in a predetermined use frequency band (for example, 2 GHz band, 800 MHz band, etc.). The communication unit 40 demodulates the signal received from the antenna 41 and supplies the processed signal to the control unit 30. Also, the signal supplied from the control unit 30 is modulated and transmitted to an external device via the antenna 41.

Furthermore, the storage unit 50 stores a speech recognition dictionary 51 and is referred to when speech recognition is performed by the speech recognition unit 60. Note that the speech recognition dictionary 51 is data including choices of reading kana to be collated with text information obtained as a result of speech recognition. Each of these reading kana is associated with each function that can be activated, and when the reading has the same reading kana as the result of speech recognition, the associated function is executed by the control unit 30. Is done.

  In addition, the storage unit 50 has a function information DB 52 including identification data of functions that can be executed by voice recognition and identification data of functions that are restricted in execution in each restriction mode. , To the control unit 30 and the determination unit 70.

  The voice recognition unit 60 executes a voice recognition process on the signal input from the microphone 12 based on a command from the control unit 30, and is executed among a plurality of functions based on the voice recognition dictionary according to the processing result. A function to be specified is specified and provided to the control unit 30.

  The determination unit 70 refers to the function information DB 52 to determine whether or not the function specified by the voice recognition unit 60 is restricted in execution in the currently set restriction mode, and notifies the control unit 30 of the function. . In addition, the determination unit 70 determines which restriction mode the current restriction state corresponds to from among a plurality of restriction modes whose functions are restricted in the restricted state, and notifies the control unit 30 of the restriction mode. .

FIG. 3 is a diagram showing an example of screen transition by voice recognition according to the present embodiment.
In the voice recognition screen (a), when “simple answering memo setting” is input as a voice, if the execution of the corresponding function is not restricted, it is executed normally and the setting screen (b) is transitioned to.

  On the other hand, for example, when the drive mode is set and in a restricted state, the function “simple answering machine setting” specified by voice recognition and the current restriction mode “drive mode” are displayed, and the specified function is executed. It is notified that it is not done (c).

  As described above, the control unit 30 displays only the specified function and the restriction mode based on the notification from the determination unit 70, thereby notifying only that the function cannot be executed, such as “This function cannot be called”. Compared to the error display, detailed information can be provided to the user.

FIG. 4 is a diagram showing a screen display example of the operation restriction list according to the present embodiment.
For example, in the voice recognition screen, when “operation restriction list” is inputted as a voice, if there is no restricted function, “no operation restriction” is displayed (a).

  On the other hand, if there is a restricted function, an operation restriction list, which is a list of functions that can be recognized by voice but restricted, is displayed based on the identification data acquired from the function information DB 52 (b). ).
