By receiving vibration, the user is notified of the reception of the mail.

Step ST3:
The control unit 5 determines whether or not it is a setting for performing emotion mail processing for determining the emotion level of the body text of the mail received by the transmission / reception unit 1 and performing emotion level voice notification, and performing setting for emotion mail processing. If YES in step ST4, the process proceeds to step ST4. If it is not set to perform emotion mail processing, the process is terminated under the control of the control unit 5 and the normal standby state is restored.
Step ST4:
The analysis unit 51 analyzes the text of the mail received by the transmission / reception unit 1 in step ST1.

Step ST5:
The parameter calculation unit 52 calculates the emotion level of the entire received mail text based on the analysis result in step ST4 of the analysis unit 51.
Step ST6:
The voice notification control unit 531 determines whether or not the emotion level calculated by the parameter calculation unit 52 in step ST5 is a predetermined emotion level. If the emotion level is the predetermined emotion level, the melody corresponding to the emotion level is stored in the memory. 4 is read out from the melody data list 4 and the process proceeds to step ST7, and if it is not the predetermined emotion level, the process proceeds to step ST8.
That is, for example, when the predetermined emotion level is set to “laugh”, when an email with an emotion level of “surprise” or “tears” is received, the process proceeds to step ST8, and the emotion level of “laughter” Only when the e-mail is received, the melody corresponding to “laughter” is read from the memory 4 and the process proceeds to step ST7.
Note that the predetermined emotion level may be, for example, the emotion level set by the user during normal standby or the like, or may be the emotion level set in advance when the mobile phone 100 is shipped. In this embodiment, the determination method of a predetermined emotion degree is not limited.
Further, the predetermined emotion level does not need to be one. For example, “laughter” and “surprise” are the predetermined emotion levels, and a plurality of emotion levels can be set to the predetermined emotion levels. Also good.

Step ST7:
The voice notification unit 532 reproduces the melody read from the memory 4 by the voice notification control unit 531 in step ST6, and notifies the user of the emotion level of the received mail.
Step ST8:
The timer unit 55 proceeds to step ST9 when a predetermined time has elapsed since the mail reception of the transmission / reception unit 1 at step ST1, and repeats step ST8 when the predetermined time has not elapsed.
The predetermined elapsed time may be, for example, an elapsed time set by the user at the time of normal standby or the like, or may be an elapsed time set in advance when the mobile phone 100 is shipped. In the present embodiment, the method for determining the predetermined elapsed time is not limited.

Step ST9:
The confirmation determination unit 54 determines whether or not the user has confirmed the mail. If the confirmation has not been performed, the process proceeds to step ST10. If the confirmation has been performed, the process ends, and the control unit The normal standby state is restored by the control of 5. In addition, it is good also as a structure which returns to ST9 regularly until it determines with the user confirming mail after returning to a standby state. In that case, the interval to return to ST9 may be set in the timer unit 55 in advance.

Step ST10:
The voice notification control unit 531 determines again whether or not the emotion level calculated by the parameter calculation unit 52 in step ST5 is a predetermined emotion level. If the emotion level is the predetermined emotion level, the voice notification control unit 531 determines a melody corresponding to the emotion level. The process is read from the melody data list in the memory 4 and proceeds to step ST11. When the degree of emotion is not a predetermined level, the process is terminated, and the control unit 5 controls to return to the normal standby state.
The predetermined emotion level in this step may or may not be the same as the predetermined emotion level in step ST6. That is, even if it is determined in step ST6 that it is not the predetermined emotion level, it is determined in this step that it is the predetermined emotion level, and the melody corresponding to the emotion level is read from the melody data list in the memory 4. In some cases, the process proceeds to step ST11. For example, even if the emotion level calculated by the parameter calculation unit 52 is “laughter” and it is determined in step ST6 that the emotion level of “laughter” is not determined to be a predetermined emotion level, this step May be set so that the emotion level of “laughter” is determined to be a predetermined emotion level.
Also, the predetermined emotion level in this step may be, for example, the emotion level set by the user during normal standby, or may be the emotion level preset at the time of shipment of the mobile phone 100. The method for determining the predetermined emotion level is not limited in this embodiment.
Also, the predetermined emotion level in this step need not be one as in step ST6, and a plurality of emotion levels may be set to the predetermined emotion level.

Step ST11:
The voice notification unit 532 reproduces the melody read from the memory 4 by the voice notification control unit 531 in step ST10, and notifies the user of mail reception according to the degree of emotion.

  As described above, according to the mobile phone 100 of the present embodiment, the received text message is analyzed, a parameter based on a predetermined criterion is calculated based on the analysis result, and the parameter is determined according to the calculated parameter. Therefore, the user can know the tendency of the content of the mail without requiring a visual recognition operation.

  In addition, according to the mobile phone 100 of the present embodiment, the reception notification unit 53 displays mail reception information on the display unit 3, sounds a voice in the voice input / output unit, or vibrates notification in response to reception of a mail. After performing a notification operation such as vibrating the housing of the mobile phone 100 in the unit, the voice notification unit 532 performs a voice notification according to the emotion level, so that the user responds to the emotion level during the mail reception notification. It is possible to prepare to listen to the notification by voice, and it becomes difficult to miss the voice according to the degree of emotion.

  In addition, according to the mobile phone 100 of the present embodiment, the voice notification control unit 531 causes the voice notification unit 532 to notify the emotion level only with respect to the mail text having a predetermined emotion level. Only the user can be notified by voice.

  Also, according to the mobile phone 100 of the present embodiment, the timer unit 55 measures the elapsed time from the normal incoming call notification by the reception notification unit 53, and confirms that the mail has not yet been confirmed by the user after the predetermined time has elapsed.
