In 3, the input level of the audio signal is set to have an optimum volume. By controlling the recording in the conference mode, it is possible to clearly record a low-volume sound from a distance.

FIG. 5 is a flowchart of the recording process in the voice recorder function of the mobile phone according to the embodiment of the present invention. When executing the recording process, first the CPU
The memory 15 checks the remaining capacity of the memory 16 and determines whether new audio data can be stored, that is, whether recording is possible (S301).

When it is determined that the memory 16 does not have sufficient remaining capacity and new voice data cannot be stored (No in S301), the CPU 15 displays an error screen on the LCD 14 (S317). . FIG. 7 is an explanatory view showing an error screen, and informs that the remaining capacity of the memory is small. When the key assigned with the “confirm” command displayed on the error screen of FIG. 7 is pressed down, the CPU 15 ends the recording process and returns to FIG.
The LCD 1 displays the registered data list display screen shown in FIG.
Display on 4.

When it is determined in the process S301 that the memory has a remaining capacity for storing voice data (S3).
(Yes in 01), the CPU 15 displays the recording screen as LC.
Display on D14 (S302) and start recording (S3)
03). Along with the recording process, the CPU 15 measures the recording time and monitors the recording start date, the recording start time and the recording completion time, and displays the measured time on the recording screen on the LCD 14. The CPU 15 measures the recording time by referring to the built-in clock built in the mobile phone, and acquires the recording start time and the recording end time. In this mobile phone, a timer may be separately provided, and the CPU 15 may measure the recording time by using the timer.

Further, the CPU 15 inputs the recording start date and the recording start time in the new voice data registration date and time column of the voice registration table in the memory 16. As shown in FIG. 2, the voice registration table is a table that stores information about voice data, and the registration date and time for each voice data,
Register the start time, end time, memo content, and protection flag. When recording new voice data, the CPU 15 gives a new voice data number and inputs each data in the corresponding column of the voice registration table. In FIG. 2, the leftmost column is the voice data number.

In the voice recorder function of the present mobile phone, the input level of the audio signal is adjusted using either the method of adjusting the gain in the microphone amplifier 12 or the method of adjusting the input level of the audio signal in the DSP 13. The operation of adjusting the input level of the audio signal in each method will be described below.

In the method of adjusting the gain in the microphone amplifier 12, the recording instruction in the conference mode is given by the keypad 1.
7, the CPU 15 first adjusts the gain of the microphone amplifier 12 so that the microphone amplifier 12 amplifies the audio signal in the conference mode. Specifically, the CPU 15 switches to the conference mode gain prepared in advance by the microphone amplifier 12. After that, when the voice recorder function is operated in this mobile phone, the voice signal input from the microphone 11 is amplified by the microphone amplifier 12 with the gain in the conference mode, and the DSP 13
Is output to.

By adopting the method of adjusting the gain in the microphone amplifier 12, the voice signal is amplified more than usual, so that this mobile phone can clearly record the voice from a distance.

On the other hand, in the method of adjusting the input level of the audio signal in the DSP 13, when a recording instruction in the conference mode is input from the keypad 17, the CPU 15 causes the DS 15
Output a signal to P13 to instruct recording in conference mode,
The microphone amplifier 12 amplifies the audio signal with the gain in the normal mode and outputs it to the DSP 13. The DSP 13 measures the input level of the amplified audio signal and adjusts the input level of the audio signal so that the volume is optimum for recording. Here, the DSP 13 has previously determined the optimum volume for recording, and performs adjustment by calculating the audio signal so that the volume becomes the relevant volume.

By adopting the method of adjusting the input level of the voice signal in the DSP 13, the mobile phone can record the voice at the optimum input level regardless of the distance to the speaker and the volume of the voice. For example, when the user speaks out loud near the microphone, the DSP 13 adjusts the electric signal so as to lower the input level, so that the voice can be recorded at the averaged input level.

Further, the DSP 13 may adjust the input level of the electric signal while performing voice recognition. Specifically, when recording the voices of multiple speakers, the DSP
Reference numeral 13 identifies each speaker by voice recognition, calculates the distance between the microphone 11 and each speaker, and adjusts the input level of the voice of each speaker according to the calculated distance. By making such adjustments, the input level can be adjusted for each speaker in accordance with the distance to each speaker and the volume of the sound, so that the sound can be recorded at the average input level for each speaker. The above is the operation of adjusting the input level of the audio signal in each method.

In the recording process, the DSP 13 outputs the input voice signal to the CPU 15 as digital voice data together with the input level information. The CPU 15 stores the voice data in the memory 16 and stores the input level information in the L level.
It is displayed on the recording screen on the CD 14.

The number of displayed bars indicates the strength of the input level, and the larger the number of displayed bars, the stronger the input level. In this mobile phone, the input level of the voice data may be displayed in another format, such as a numerical value or a bar graph.

When the present mobile phone adopts the method of adjusting the gain of the microphone amplifier 12, the CPU 15 causes the D
When it is determined that the input level has not reached the desired value by referring to the information on the input level of the audio data output from SP13, control is performed to adjust the input level of the audio signal. Specifically, the CPU 15 controls the gain of the microphone amplifier 12 so that the input level of the audio data becomes a desired value. The CPU 15 measures the level difference between the desired value and the audio data, and adjusts so as to complement the gain corresponding to the level difference.

Also, with the present mobile phone, the user can manually adjust the input level of the audio data by referring to the recording volume level meter 65 on the recording screen and depressing the volume key on the keypad 17. At this time, by pressing down the volume key, a signal for adjusting the volume (volume adjustment signal) is output from the volume key to the CPU 15,
The CPU 15 uses the microphone amplifier 1 based on the volume adjustment signal.
In the gain adjustment in 2, the gain adjustment control of the microphone amplifier 12 is performed, and in the input level adjustment in the DSP 13, the input level adjustment control is performed on the DSP 13.
