FIG. 1 is a block diagram illustrating an example of a system configuration of a mobile phone 10 as a mobile terminal device of the present invention. FIG. 2 is a diagram illustrating an example of the appearance of the mobile phone 1.
The mobile phone 10 is a so-called foldable mobile phone having a movable mechanism. FIG. 2A is a front view in an opened state (open state), and FIG. 2B is a closed state (closed state). (C) is a side view in the open state, and (d) is a side view in the closed state.

The mobile phone 10 according to the present embodiment has a voice reading function in addition to the function of a normal mobile phone, and when the mobile phone 10 receives a reading instruction, a warning sound is generated before the reading. It is configured to alert the user (listener) and obtain a psychological effect.
In the mobile phone 10, the alarm is sounded only when the voice reading function is set to “automatic” and it is necessary to inform the user of a particularly important status such as the radio wave status or the remaining battery level.
When the mobile phone 10 according to the present embodiment reads out when receiving an incoming call or mail, the mobile phone 10 does not emit a normal warning sound because the ringtone and ringtone play a role of a warning sound before the reading time.
That is, the mobile phone 10 is configured not to emit a warning sound until it is in a state where it can be clearly heard.
In addition, it is comprised so that it can be judged instantaneously that a user's terminal can be read aloud because the user can set the warning sound.

In the mobile phone 10 according to the present embodiment, as will be described in detail later, the following two points exist regarding the condition of “warning sound generation”.
The first is that a warning sound is generated with reference to the condition table.
The second is not a fixed setting as in the condition table, but a weighting value is given in advance to each event (event), and in what range the user sounds a warning sound, the weighting value in the weighting table and the user The user's convenience is improved by comparing the set values and controlling the sounding and non-ringing of the warning sound.

  Hereinafter, the configuration and function of each unit of the mobile phone 10 according to the present embodiment, and the voice reading control will be described in order.

As shown in FIG. 1, the mobile phone 10 includes a communication processing unit 11 including a transmission / reception antenna 111, a memory 12, a key operation unit 13, a dial input unit 14, a sub display unit 15, and a main display unit 16. , A voice synthesis processing unit 17 including a speaker 171 and a microphone 172, an open / close switch 18, a reading key input unit 19, a warning sound generation unit 20, and a control unit (CPU) 21.

The communication processing unit 11 performs a wireless communication operation via the base station, for example, a telephone number calling operation or an e-mail transmission / reception operation.
The communication processing unit 11 is configured to include a transmission / reception antenna 111. In order to perform wireless communication using radio waves, the communication processing unit 11 modulates voice information, e-mail, and the like processed by the control unit 26, and a base (not shown) by the transmission / reception antenna 111. Send to the station.
In addition, the communication processing unit 11 demodulates various information such as e-mail and voice information transmitted from the base station by radio and received by the transmission / reception antenna 111 and outputs the demodulated information to the control unit 26.
The transmission / reception antenna 111 is built in the key input side main body case 101 or the display side main body case 102 and is not exposed to the outside in FIG.

The memory (storage unit) 12 includes a nonvolatile memory such as an EEPROM, and stores a control program for sending and receiving calls and mails, an Internet browser, message data, an address book in which names and telephone numbers are registered, and the like. To do.
The memory 12 stores a speech reading database including a text string necessary for a reading function to be described later. In this database, text strings for reading are systematically arranged so that the connection relationship before and after is established as a sentence.
The memory 12 stores a control table and a weighting table for the voice reading function.
The memory 12 stores “standard text”, “abbreviated text”, and “explanatory text” for each menu item displayed on the display unit.

The key operation unit 13 has an end (end call) / power key, a start (call) key, a plurality of numeric keys corresponding to numbers, etc., and when these keys are operated by the user, Input information is output to the control unit 21.
Further, whether or not to read each item in the control table of the voice reading function stored in the memory 12 (ON / OFF) can be set through the control unit 21 by operating the key operation unit 13.
In addition, by operating the key operation unit 13, the weight value of each item in the weighting table of the speech reading function stored in the memory 12 can be set through the control unit 21.

As shown in FIG. 2C, the dial input unit 14 is disposed on the side surface of the display-side main body case 102 so that the user can easily operate with the thumb of the user when holding the mobile phone 10 in the open state. The dial-type input unit is configured to be operated in two directions.
By operating the dial input unit 14, the user can change the sound output volume and the character size displayed on the sub display unit 15 and the main display unit 16.
Further, as apparent from FIGS. 2C and 2D, when the dial input unit 14 in the closed state and the open state are compared, the operation directions in the upper and lower directions are physically reversed. In the form, in order not to cause a sense of incongruity for the user, the operation direction viewed from the user and the action on the operation (for example, the above-described volume change and display font size (character size to be displayed) change) always match. It is controlled by the control unit 21 described later.

The sub display unit 15 has a display device such as a liquid crystal display (LCD) and is visually recognized by the user in the closed state as shown in FIG.
The main display unit 16 includes a display device such as a liquid crystal display (LCD) and is visually recognized by the user in the open state as shown in FIG.
The sub display unit 15 and the main display unit 16 display the text of the received e-mail and various text data stored in the memory 12 in the closed state and the open state, respectively.

The voice synthesis processing unit 17 has a voice processing circuit, and is connected to a speaker 171 that outputs voice for a call function and a microphone 172 that inputs voice.
The sound processing unit 17 performs predetermined processing on the sound collected by the microphone 172 and supplies the processed sound to the control unit 21. The audio processing unit 17 performs predetermined processing on the audio information supplied from the control unit 21 and outputs the audio information from the speaker 171.
Further, as shown in FIGS. 2A and 2B, the speaker 171 includes two voice output units of a reception speaker 171a and a ringer speaker 171b, and outputs a voice that is a processing result of the reading function.
Furthermore, the speech synthesis processing unit 17 has a speech synthesis circuit, and converts the text data read out and extracted from the memory 12 by the control unit 21 into speech data when performing reading, and is a speech output unit. The voice is synthesized by the receiving speaker 171a or the ringer speaker 171b and outputted.
When the speech synthesis processing unit 17 reads the speech, the speech output unit outputs speech data synthesized by the reception speaker 171a or the ringer speaker 171b under the control of the second control signal CTL2 by the control unit 21. Depending on the reason for starting to read, the warning data is output from the voice output unit and then the voice data is output.

The open / close switch 18 is a switch for detecting the open / closed state of the mobile phone 10.
Various technologies can be applied to the specific configuration of the open / close switch 18. For example, as shown in FIG. 2A, a contact portion is provided on each of the key input side main body case 101 and the display side main body case 102. In the closed state (FIG. 2 (b)), the two contacts are electrically non-conductive so that the device can be turned off.
For example, the mobile phone 10 is configured to be in an on state (ON state) when the mobile phone 10 is in a closed state, and the open / close switch 18 is in an off state (OFF state) in an open state. By detecting, the open / close state of the mobile phone 10 is determined.

As shown in FIG. 2B, the reading key operation unit 19 includes a push-down button 19a disposed in the center of the display-side main body case 102, and an input circuit for switch input by the button. The
The cellular phone 10 according to the present embodiment has a reading function. When the push button 19a is pressed (operated), for example, the voice is output from the ringer speaker 21 in the closed state, and the voice is output from the receiving speaker 171 in the open state. In this way, the control unit 21 controls the operation.
The control unit 21, which will be described later, determines the open / closed state of the mobile phone 10 based on the output of the open / close switch 18, and then notifies the voice synthesis processing unit 17 of the voice output destination for reading.

  The warning sound generating unit 20 receives the first control signal CTL1 from the control unit 21 and generates a warning sound, for example, a warning sound “ping-pong”, and sends the warning sound to the speech synthesis processing unit 17 through the control unit 21 or directly. Supply.

  The control unit 21 is mainly composed of a microcomputer and controls the entire mobile phone 1. For example, the control unit 21 controls transmission / reception of various types of information in the communication processing unit 11, processes audio information for the audio processing unit 17, controls display of information on the main display unit 16, and inputs information to the key input unit 13. Responsive processing, access control to the memory 12, and the like are performed.

  When the user operates the push button 19a, the control unit 21 executes a function for reading out the displayed text. At that time, the text-to-speech method is used as a text-to-speech function, rather than a system that outputs speech data for text-to-speech, and a text string is extracted / generated and the text is read out.

When outputting the sound data, the control unit 21 generates a warning sound by the control signal CTL1 according to the reason for starting the reading and outputs the warning sound from the speaker which is the sound output unit, and then outputs the sound data. The second control signal CTL2 is output to the speech synthesis processing unit 17.
In other words, when outputting the voice data, the control unit 21 generates a warning sound by the first control signal CTL1 according to the reason for starting reading, and then converts the text to the voice data by the second control signal CTL2. Control to convert to.
The control unit 21 causes the speaker 172 that is an audio output unit to output a warning sound and outputs audio data after a predetermined time has elapsed.
That is, the control unit 21 causes the voice synthesis processing unit 17 to generate voice data using the second control signal CTL2 after a predetermined time has elapsed after the warning sound is generated by the warning sound generation unit 20 using the first control signal CTL. .
Further, when there is an input from the key operation unit 13 during a predetermined time, the control unit 21 does not output audio data through the speaker 172 that is an audio output unit.
The key operation unit 13 is associated with a predetermined process, and when there is an input from the key operation unit 13 during a predetermined time, the control unit 21 outputs audio data through the speaker 172 that is an audio output unit. Control is performed so that predetermined processing is not performed only by not outputting.

Further, the control unit 21 determines whether the reading is started by the reading key operation unit 19 or the automatic reading according to the state transition in the terminal as a reason for starting the reading.
This automatic reading is based on, for example, transition of the remaining battery level or radio wave status.
At the time of this automatic reading, the control unit 21 refers to the control table of the voice reading function stored in the memory 12.

FIG. 3 is a diagram illustrating an example of a control table according to the present embodiment.
In the example of FIG. 3, the categories of automatic reading are divided into the remaining battery level, radio wave status, and others.

The mobile phone 10 is supplied with power by a secondary battery (hereinafter referred to as a battery) (not shown), and the control unit 21 grasps the remaining battery level by constantly monitoring the voltage value of the battery. A battery flag is set depending on whether the battery voltage value is equal to or higher than a predetermined threshold value, and the threshold value is provided at a plurality of levels. Based on this, the battery flags are designated as 0, 1, 2, and 3 in order from the smallest remaining amount, and are displayed on the display units 15 and 16.
The battery status divides whether or not to read out with 0, 1, 2, 3 battery flags displayed on the display units 15 and 16, for example.
In accordance with the control table, when the battery flag is 0 and 1, the control unit 21 reads out “battery level is low” before informing the user that the battery level is extremely low. The generation control and the reading-out control of the warning sound are performed as in the case of performing.
When there are two and three battery flags in accordance with the control table, the control unit 21 does not perform the reading-out control on the assumption that the battery remaining amount is not notified to the user.

In the mobile phone 10, the communication processing unit always performs an operation of ensuring communication with a neighboring base station by transmitting and receiving a radio signal through the antenna 111. Here, the strength of the radio wave from the base station as seen from the mobile phone 10 changes as the mobile phone 10 moves or the surrounding environment changes. The control unit 21 also provides a plurality of threshold values for the intensity of the radio wave, and designates 0 to 3 radio wave marks for each. Further, when the minimum radio wave intensity that allows communication is not obtained, it is designated as out of service area, and these are displayed on the display units 15 and 16.
The radio wave status is divided, for example, whether the radio waves displayed on the display units 15 and 16 are out of service area, 0 radio waves, 1 radio wave, 2 radio waves, or 3 radio waves.
In accordance with the control table, the control unit 21 reads out, for example, “the radio wave condition is bad at the current position” for the radio wave out of service area, zero radio wave, and one radio wave, assuming that the radio wave condition is extremely bad for the user. Thus, the generation control and the reading-out control of the warning sound are performed.
In accordance with the control table, when the radio wave is two radio waves or three radio waves, the control unit 21 does not perform the reading-out control as not to notify the user of the radio wave condition.

Others include when charging is complete, during a call, when radio wave conditions are restored, incoming calls, mail reception (in this case, the received sound is a warning sound), unread mail, and absence of recorded messages.
In accordance with the control table, the control unit 21 warns to notify the user when charging is complete, during a call, when the radio wave condition is restored, incoming, or mail is received (in this case, the received sound is a warning sound). Performs sound generation control and reading-out control.
In accordance with the control table, the control unit 21 does not perform the reading-out control because it has another notification function when there is an unread mail and an answering machine.
The control unit 21 does not perform voice reading control during the manner mode, the drive mode, or the key lock.

In this automatic reading, the control unit 21 refers to the weighting table of the voice reading function stored in the memory 12.
The control unit 21 determines whether automatic reading is performed or not according to the weighting value of the weighting table.

FIG. 4 is a diagram illustrating an example of a weighting table according to the present embodiment.
In the example of FIG. 4, the category of automatic reading is divided into the remaining battery level and the radio wave status.

The battery status is divided as to whether or not to perform reading by changing the weighting value when the battery flags displayed on the display units 15 and 16 are 0, 1, 2, 3, for example.
In accordance with the control table, for example, when there are 0 and 1 battery flags having weight values of 4 and 3, the control unit 21 informs the user that the remaining battery level is very low, Alarm sound generation control and reading-out control are performed so that the reading is read out.
When there are two and three battery flags with weighting values 2 and 1 according to the control table, the control unit 21 does not perform the reading-out control as not to notify the user of the remaining battery level.

The radio wave status is divided, for example, whether the radio waves displayed on the display units 15 and 16 are out of service area, 0 radio waves, 1 radio wave, 2 radio waves, 3 radio waves, and whether to perform reading by changing the weight value.
According to the control table, the control unit 21 determines that, for example, the out-of-service weighting value of 5, 4, 3 is 0, 1 radio wave, and 1 radio wave indicate that the radio wave condition is extremely bad for the user. The sound generation control and the reading-out control are performed so that the reading is read out.
In accordance with the control table, the control unit 21 does not perform read-out control on the assumption that there is no need to notify the user of the radio wave status when the radio waves having the weight values of 2 and 1 are two radio waves and three radio waves.

When the communication unit 11 receives or receives information from the communication network, the control unit 21 gives an instruction to the voice synthesis processing unit 17 that generates a notification sound.
The control unit 21 causes the sound output unit to output a warning sound when the reason for starting reading is the occurrence of information reception or incoming processing and the notification sound is output from the speaker 172 as the sound output unit.

The control unit 21 includes a text extraction unit (not shown), and the text extraction unit 261 extracts text from a database such as a menu, mailer, or browser stored in the memory 12 according to the text extraction rule, and performs speech synthesis processing. Supply to unit 17.
At that time, the control unit 21 sequentially scans the text string from the first character, refers to the reading database in the memory 12 in advance, and performs speech synthesis in units of sentences while considering the connection relationship before and after. The text data is supplied to the speech synthesizer 20. Further, the control unit 21 performs control so as to perform, for example, sentence-by-sentence speech synthesis, and according to this reading function, for example, it is possible to change to male sound, change to female sound, change the reading speed, and the like. .

In addition, when the sub-display unit 15 or the main display unit 16 displays text, when a dial input is made in the upward direction of the mobile phone 1, the character size of the displayed text is increased. When a dial input is made in the downward direction of the mobile phone 1, each display unit is controlled so that the character size of the displayed text is reduced.
Since the character information is stored in the memory 12 as a scalable font or as a plurality of fonts having different sizes, the control unit 21 extracts the character information from the memory 12 and displays it on each display unit.
Here, in the state shown in FIG. 2B, it is assumed that the mobile phone 1 displays a text font with the ringer speaker 21 side as the lower side.

As described above, the control unit 21 performs processing according to the dial input from the dial input unit 14, and at that time, performs reversal processing according to the open / closed state of the mobile phone 1.
In general, for a dial operation in the vertical direction, the user expects an increase in action for an upward operation and a decrease in action for a downward operation. Regardless of the open / closed state of the telephone 1, the process for realizing the above-described action in accordance with the user's expectation is the inversion process.

In other words, when the cellular phone 1 is in the closed state (FIG. 2B), as described above, for example, when processing is performed so that the character size is enlarged / reduced according to the input in the vertical direction of the dial, If no other processing is performed, when the cellular phone 1 is in the open state (FIG. 2A), the vertical position direction of the dial input unit 14 for the user is reversed compared to the closed state. The character size is reduced in response to the input, and this results in an unnatural feeling for the user.
Therefore, the control unit 21 determines the open / closed state of the mobile phone 1 based on the output of the open / close switch 18, and performs an inversion process of the action on the dial input unit 14 according to the open / closed state. Accordingly, when viewed from the user, regardless of the open / closed state of the mobile phone 1, an upward operation on the dial input unit 14 always increases the character size and a downward operation on the dial input unit 14 Thus, the operation is performed in the direction of reducing the character size, so that there is no sense of incongruity and operability is improved.

Heretofore, each component of the mobile phone 10 has been described.
Next, the voice reading control of the mobile phone 10 according to the present embodiment will be specifically described with reference to FIGS.

First, the basic operation of the reading operation according to the present embodiment will be described with reference to FIG.
FIG. 5 is a flowchart for explaining the basic operation of the reading operation according to this embodiment.

Basically, it operates by transitioning to a state where it can be read out.
First, when it is necessary to read out and notify the operation of the reading key operation unit 19 or some event, for example, the remaining battery level or the radio wave condition (ST1), first, the reading instruction is based on the operation of the reading key operation unit 19 It is determined whether or not it is a thing (ST2).
If it is determined in step ST2 that the operation is based on the operation of the reading key operation unit 19, a desired text is extracted from the memory 12, and the control signal CTL2 is output to the speech synthesis processing unit 17 so that the speech data is obtained by speech synthesis. Generate and output audio data (ST3).
In this case, the warning sound is not generated because it depends on the user's will.

If it is determined in step ST2 that it is not based on the operation of the reading key operation unit 19, it is determined that it is based on automatic reading (ST4), and the reading for the operation is performed, specifically reading when the cursor is set. Then, it is determined whether or not the numeric input is read out (ST5).
If it is determined in step ST5 that the operation is to be read out, a warning sound is not generated because it is based on the user's intention, and in step ST3, the audio reading is started. That is, a desired text is extracted from the memory 12, the control signal CTL2 is output to the speech synthesis processing unit 17, speech data is generated by speech synthesis, and speech data is output.

If it is determined in step ST5 that the operation is not read out, it is determined whether or not the mail is received or received (ST6).
If it is determined in step ST6 that a mail is received or an incoming call is received, the user receives and receives a ringtone, so that no warning sound is generated and voice reading is started in step ST3. That is, a desired text is extracted from the memory 12, the control signal CTL2 is output to the speech synthesis processing unit 17, speech data is generated by speech synthesis, and speech data is output.

If it is determined in step ST6 that the mail is not received or received, it is determined whether or not a call is in progress (ST7).
If it is determined in step ST7 that the call is a call, no warning sound is required, so no warning sound is generated and voice reading is started in step ST3. That is, a desired text is extracted from the memory 12, and the control signal CTL2 is output to the voice synthesis processing unit 17 to generate voice data by voice synthesis, adjust the volume, and output the voice data together with the voice of the other party. Let

If it is determined in step ST7 that the call is not a call, a control table or a condition table that is a weighting table is referred to (ST8).
It is determined whether or not the reading item in the condition table is ON (ST9).
If it is determined in step ST9 that the item is not ON (OFF), no warning sound is required, so that no warning sound is generated and voice reading is started in step ST3. That is, a desired text is extracted from the memory 12, the control signal CTL2 is output to the speech synthesis processing unit 17, speech data is generated by speech synthesis, and speech data is output.

If it is determined in step ST9 that the item is ON, a warning sound is necessary. Therefore, after generating a warning sound by the first control signal CTL1 (ST10), the text is sounded by the second control signal CTL2. Control to convert to data.
Specifically, after a predetermined time has elapsed since the warning sound was output, speech reading is started in step ST3. That is, a desired text is extracted from the memory 12, the control signal CTL2 is output to the speech synthesis processing unit 17, speech data is generated by speech synthesis, and speech data is output.
In this way, by starting to read out a sound after a predetermined time has elapsed, even if the warning sound output by the sound output unit 171 is a sound including a residual sound, it is superimposed on the sound to be read out, Even for a voice amplifier circuit (not shown), the supplied sound source is suddenly switched from the warning sound generating unit 20 to the synthesized sound of the voice synthesis processing unit 17, thereby avoiding a problem that the gain cannot be changed. it can.

For example, when the battery is about to run out while the mobile phone 10 is in the pocket, as shown in FIG. 6, after a warning sound “ping-pong” is emitted, the “battery remaining 1 The voice is read out. Users who have heard this can be given an opportunity to use thoughts such as buying a battery for auxiliary charging at a convenience store.
Furthermore, when there is a schedule for receiving a call and waiting for the incoming call as shown in FIG. 7, when the battery is about to run out, a warning sound “ping-pong” is issued and then “ The remaining one is read out. The user who has heard this can take measures against a call that should come in advance so that the charger is connected to the charging terminal with a connector on the assumption that the user is talking while charging.
In addition, when an e-mail is created and a transmission instruction is issued, communication with the base station is normally established after the transmission instruction is issued, and then a predetermined mail server is called to send the e-mail by a predetermined packet. In order to transmit, there is a time lag of several seconds from when the user gives an instruction to transmit until the transmission is completed. As shown in FIG. 8, when such e-mail is sent, when e-mail is created with a good radio wave condition, transmission is instructed and waiting for connection to the mail server is not yet completed. In many cases, the mobile phone 10 is put in a pocket in anticipation of successful transmission. At this time, if the radio wave condition becomes unsatisfactory after being put in the pocket, a warning sound “ping-pong” is issued and then “Please retry in a place with good radio wave” is read out. Users who have heard this can, for example, re-send later or take action such as changing the location, and prevent the situation where they do not notice the failure of sending e-mail as much as possible. Can do.

As described above, according to the present embodiment, the memory 12 that stores the text corresponding to the reading item, the warning sound generation unit 20 that generates the warning sound, and the memory 12 that is stored when reading is performed. A voice synthesis processing unit 17 that converts text into voice data, a voice output unit 171 that outputs voice data or warning sound, and a voice output unit 171 that outputs voice data depending on the reason for starting to read. Since it has a control unit 21 that controls to output sound data after the sound is output from the sound output unit, the user (listener) is alerted by sounding a warning sound before reading aloud, so Effects such as elimination can be obtained.
You can set whether reading is automatic or reading by pressing a button, and even when it is set to automatic, it is possible to prevent the user from sounding a warning sound when there is no need for a warning sound. There is an advantage that the user can set the warning sound before reading without requiring time and can generate the warning sound only when necessary.

  In addition, according to the mobile phone 10 according to the present embodiment, the characters of the displayed text can be enlarged / reduced by the operation on the dial input unit 14, the text visibility is improved, and the text characters are improved. When enlarging / reducing is performed, display processing corresponding to the display format of the text is performed, so that the user's visibility and operational comfort are further improved.
