DESCRIPTION OF THE PREFERRED EMBODIMENTS FIG. 1 is a block diagram showing a configuration example of an embodiment of a composite mobile terminal to which the mobile terminal of the present invention is applied. As shown in FIG. 1, the present embodiment has a voice recognition function and has a plurality of systems (PDC (PerCer)).
Sonal Digital Cellular) or P

) can be registered and used, and realizes mode setting and mode switching of each system using a voice recognition function.

For example, mobile phone mode, PHS mode,
A great number of standby modes, such as a home antenna mode, indoor mode (home mode, office mode), transceiver mode, and a dual mode that simultaneously waits for a PDC mode and a PHS-related mode, can be easily switched using a voice recognition function. To make it possible.

Hereinafter, referring to FIG. 1, a portable telephone (hereinafter referred to as P
A description will be given by taking a composite mobile terminal that combines PHS with DC as an example.

As shown in FIG. 1, in the present embodiment, a voice recognition circuit 8 for realizing the same voice recognition function as a voice search function for calling a telephone directory or the like by voice, and a voice recognition circuit 8 and various parts are conventionally used.

A / D-D / A / D / D / D converter 2 converts the digital audio signal supplied from
An A conversion circuit 3, an audio processing unit 2 that encodes a digital audio signal supplied from the A / D-D / A conversion circuit 3, and decodes a reception signal received by a transmission / reception unit 1 described below; A transmission / reception unit 1 for wirelessly transmitting a coded audio signal supplied from the audio processing unit 2 while supplying a received signal received wirelessly to the audio processing unit 2, and an LCD (liquid crystal) for displaying characters and graphics.
al display) and a CPU
A display control unit 7 for displaying characters and graphics corresponding to display data representing various states such as a terminal state such as a standby mode and a telephone number supplied from 6 on a display unit 9; a button for inputting a telephone number; And an operation unit 10 including a voice recognition button 11 for activating a voice recognition function.

Next, referring to the flowchart of FIG.
The operation of the present embodiment will be described. In step S1, the CPU 6 determines whether or not the voice recognition button 11 of the operation unit 10 has been pressed. If it is determined that the voice recognition button 11 has not been pressed, the process proceeds to step S
Step 1 is repeatedly executed. On the other hand, when it is determined that the voice recognition button 11 has been pressed, the process proceeds to step S2.

In step S2, the voice recognition function is activated by the CPU 6. The voice recognition function operates in the voice recognition circuit 8. Then, in step S3, it is determined whether the word "mode" is pronounced by the voice recognition function.

That is, when sound is input from the microphone 4, the input sound signal is converted into a digital sound signal in the A / D-D / A conversion circuit 3 and sent to the CPU 6 via the sound processing unit 2. Supplied. The CPU 6 supplies the digital voice signal to the voice recognition circuit 8. In the voice recognition circuit 8, a voice recognition process is performed on a digital voice signal supplied from the CPU 6 by a voice recognition function. Then, the recognition result is supplied to the CPU 6.

When it is determined that the digital audio signal supplied from the CPU 6 is an audio signal corresponding to the word "mode", a mode setting routine is started by the CPU 6 in step S4, and a state of waiting for a mode name is entered. Become. The mode setting routine is a program that performs a process for switching a mode to a mode corresponding to the mode name recognized by the voice recognition function.

Next, in step S5, it is determined by the mode setting routine whether or not the mode name has been pronounced. That is, when voice is input from the microphone 4,
The input audio signal is converted into a digital audio signal in the A / D-D / A conversion circuit 3 and supplied to the CPU 6 via the audio processing unit 2. The mode setting routine that operates on the CPU 6 supplies the digital voice signal to the voice recognition circuit 8. In the voice recognition circuit 8, a voice recognition process is performed on a digital voice signal supplied from the CPU 6 by a voice recognition function. Then, the recognition result is notified to the mode setting routine.

The mode setting routine determines, based on the recognition result, whether the audio signal input from the microphone 4 is an audio signal corresponding to a mode name of any of the various modes described above. As a result, when it is determined that the audio signal input from the microphone 4 is an audio signal corresponding to the mode name of any of the various modes described above, the process proceeds to step S6. On the other hand, when it is determined that the audio signal input from the microphone 4 is not the mode name of any of the various modes, the process of step S5 is repeatedly performed.

In step S6, the mode of the composite mobile terminal is switched to the mode corresponding to the mode name recognized in step S5 by the mode setting routine.

In step S7, display data for displaying the mode name of the mode switched in step S6 on the display unit 9 is supplied to the display control unit 7 by the mode setting routine. The display control unit 7 supplies a control signal corresponding to the display data to the display unit 9, and the display unit 9 displays the mode name according to the control signal. After that, the process ends.

In this way, it is possible to switch the mode of the composite mobile terminal only by pronouncing the desired mode name by voice.

As described above, according to the present embodiment, the following effects can be obtained. That is, the mode switching can be easily performed by realizing the switching of the standby mode in which a great number of combinations exist by voice recognition.

Although it is preferable to provide a mode switching button exclusively for the composite mobile terminal in terms of convenience for the user, the operation has become very complicated in recent years due to the multifunctionality of the composite mobile terminal. The number is also limited. Therefore, by enabling the mode setting by voice, the exclusive mode switching button can be deleted, and the number of buttons of the composite mobile terminal can be reduced.

In the above embodiment, the case where the present invention is applied to PDC and PHS has been described. However, the present invention can be applied to mobile terminals of other systems.

[0022]

As described above, according to the mobile terminal, the mode switching method, and the recording medium of the present invention, a voice is input, the input voice is converted into a digital voice signal, and the digital voice signal is converted. Recognize and according to the recognition result,
Since the standby mode is switched, the mode can be switched by voice using the voice recognition function of the composite mobile terminal, and the mode switching operation can be simplified.
