BEST MODE FOR CARRYING OUT THE INVENTION Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. Note that the present invention will be roughly divided into a first embodiment for creating an electronic mail (electronic message) to be sent and a second embodiment for checking a received electronic mail.

<< First Embodiment >> First, a first embodiment of the present invention will be described with reference to the drawings. FIG. 1 is a diagram schematically showing a vehicle equipped with an electronic mail creating device. Figure 2
FIG. 1 is a block diagram showing an overall configuration of an electronic mail transmitting device including an electronic mail creating device. FIG. 3 is a block diagram showing the functional expansion of the electronic mail creating means of FIG.

[E-mail Transmission Device] As shown in FIG. 1, the e-mail transmission device 1 is mounted on a vehicle V. Further, as shown in FIG. 2, the electronic mail transmission device 1 is configured to include an electronic mail creation device 10, operation keys KB, a microphone MC, a communication device COM, and a monitor MON. Of these, the operation key KB is an input device used for manual text input, operation of the electronic mail transmission device 1, and the like. The microphone MC is an input device used for voice inputting text. The communication device COM is a wireless communication device used for transmitting an electronic mail by a predetermined protocol to a wireless packet communication network provided by a communication carrier (mobile phone company). The monitor MON is, for example, a liquid crystal panel that visually displays the input text and the created electronic mail. The speaker SP is a speaker that outputs voice when reading the input text or the created electronic mail as voice. Incidentally, the vehicle speed sensor VS here is a speed sensor provided in the vehicle V, and transmits a vehicle speed pulse to the electronic mail creation device 10. The vehicle speed pulse is used to determine the moving state / stop state of the vehicle V.
Further, as the monitor MON, a monitor for car navigation provided in the vehicle V can be used. As the speaker SP, a car audio speaker provided in the vehicle V can be used. In addition, since communication by the wireless packet communication network is generally charged according to the number of packets transmitted and received, there is an advantage in terms of communication cost when frequently transmitting and receiving a small amount of data. In addition, as a communication carrier, multiple users put packets on the same radio wave one after another,
There is an advantage that radio waves are effectively used.

The electronic mail creating apparatus 10 has a C (not shown).
It is composed of a PU, a RAM, a ROM, a hard disk, an input / output interface, a power supply device and the like, and has an electronic mail creating means 11, a communication processing means 12, a display processing means 13 and the like as shown in FIG. Of these, the electronic mail creating means 11 is a key operation input from the operation keys KB and a microphone MC.
It has a function of creating text by voice input from, and creating an e-mail based on the created text. The electronic mail creating means 11 will be described later in detail with reference to FIG. Also, the communication processing means 12
Is an email created by the email creating means 11,

The display processing unit 13 has a function of displaying the text, the electronic mail, and other information created by the electronic mail creating unit 11 via the monitor MON.

[Electronic Mail Creating Means] As shown in FIG. 3, the electronic mail creating means 11 includes a key input unit 111, a text conversion unit 112, a voice input unit 113, a voice text conversion unit 114, a voice text conversion DB 115, and a vehicle speed. Pulse input unit 116, vehicle state determination unit 117, text switching unit 118, transmission text processing unit 119, text storage unit 120, switching announcement unit 121, speech synthesis DB 12
2, a voice output unit 123, an electronic mail creation unit 124, and the like. These are the electronic mail creating means 11
It is assumed that it is configured as a program that functions inside, but may be configured as hardware.

The key input unit 111 has a function of receiving a key input from the operation key KB. Text converter 1
Reference numeral 12 has a function of converting a key input into a corresponding text. The text conversion unit 112 has a function of searching a kana conversion dictionary or a kanji conversion dictionary (not shown).
The text conversion unit 112 also has a well-known function of selecting homophones and re-segmenting phrases when converting Kanji by key input from the operation keys KB. Incidentally, the key input unit 111 and the text conversion unit 112 correspond to the "first text input means" in the claims.

The voice input section 113 has a function of receiving voice input from the microphone MC. The voice / text converter 114 has a function of recognizing an input voice and converting it into a corresponding text. Speech text conversion DB115
Is a DB used by the voice / text converter 114 to convert voice into text. The text conversion unit 1
Reference numeral 12 has a function of searching the above-described Kana conversion dictionary or Kanji conversion dictionary (not shown). The voice-text conversion unit 114 has a well-known function of performing selection of homonyms and re-segmentation when converting Kanji by voice input from the microphone MC. By the way, the voice input unit 113, the voice text conversion unit 114, and the voice text conversion DB 115.
Corresponds to the "second text input means" in the claims.

In the voice-text conversion unit 114, a process of creating an input pattern (unknown input pattern) consisting of parameters representing the characteristics of the voice obtained by analyzing the input voice, and the created unknown input pattern A process of comparing, by pattern matching, a registered pattern (dictionary data [speech / text conversion DB 115]) stored in a database for a plurality of voices in advance, and as a result of comparison, registration of dictionary data having a small distance between them (that is, a large likelihood) The process of outputting a pattern as the result of voice recognition.
The recognition result is converted into text by referring to a kana conversion dictionary or a kanji conversion dictionary (not shown). By the way, the likelihood (distance) is a parameter that represents the likelihood of a candidate of the speech recognition result, and a hidden Markov model (modeled statistically with a large number of learning samples for spectral fluctuation and temporal fluctuation of the speech). Hidden Markov Mo
del) etc. Of course, the processing of the voice recognition here is an example, and is not limited to this means / method.

Next, the vehicle speed pulse input section 116 has a function of receiving the input of the vehicle speed pulse detected by the vehicle speed sensor VS. The vehicle state determination unit 117 determines whether the vehicle V is in a stopped state or a moving state (running state) based on a vehicle speed pulse input within a predetermined time. For example, if there is not 1 pulse (1 shot) of the vehicle speed pulse input in 1 second, it is determined that the vehicle V is in the stopped state, and conversely, if 1 pulse (1 shot) is input, it is determined to be the moving state. Then, the vehicle state determination unit 117 sets a vehicle stop flag (0; stop state, 1; moving state). The set vehicle stop flag is output to the text switching unit 118 and the switching announcement unit 121. Incidentally, the vehicle state determination unit 117 corresponds to "vehicle state determination means" in the claims. To determine whether the vehicle V is in a moving state or a stopped state, a shift position signal, a brake switch signal, a rotation speed signal of a prime mover, a torque command value to a traveling motor, or the like may be used in combination as appropriate or independently. It can be used in. Also,
The vehicle speed signal can also be used. Generally, the vehicle V
The vehicle speed is managed by converting the vehicle speed pulse into 8-bit data (that is, 0 to 255 km / h [resolution 1 km / h]).

By the way, in recent years, an increasing number of vehicles V perform an idle stop of the engine at a stop such as waiting for a signal. For such a vehicle V, an idle stop signal / restart signal for an engine (injector) or a starter is provided. The text input may be switched by inputting. In this case, the vehicle state determination unit 117 in FIG. 3 is omitted, and the vehicle speed pulse input unit 116 uses the idle stop signal (stop state) / restart signal (moving state) as the vehicle stop flag and the text switching unit 118 and the switching announcement. It is possible to transmit (output) to the unit 121. In addition, in this case, "vehicle state determination means" in the claims
Corresponds to the portion for inputting the idle stop signal / restart signal, that is, the vehicle speed pulse input unit 116 in FIG. That is, the "vehicle state determination means" in the claims is
It includes a so-called "vehicle state determination input means" for inputting a signal for determining the vehicle state of whether the vehicle V is in the stopped state and / or in the stopped state. By inputting the idle stop signal / restart signal, the configuration of the electronic mail creating means 11 can be simplified.

Next, the text switching unit 118 outputs the text from the text conversion unit 112 to the voice text conversion unit 11.
4 and the vehicle stop flag from the vehicle state determination unit 117 are input to switch the text. Specifically, when the vehicle stop flag is set to 0, that is, when the vehicle V is stopped, the text from the text conversion unit 112 is output to the transmission text processing unit 119 in the subsequent stage. On the other hand, when the vehicle stop flag is set to 1, that is, when the vehicle V is moving, the text from the voice text conversion unit 114 is output to the transmission text processing unit 119 in the subsequent stage. Further, when the vehicle V moves while the text is being created by key operation while the vehicle V is stopped, the text switching unit 118 switches to text input by voice input. If the vehicle V is stopped while the text is being created by voice input while the vehicle V is moving, the text switching unit 118 switches to text input by key operation (of course, the voice input may be continued as it is). . This text switching unit 1
Reference numeral 18 corresponds to the "first input switching means" in the claims. The text switching unit 118 also corresponds to the "second input switching unit" in the claims. The input can be switched using the operation key KB.
It also includes preventing text input from the operation key KB even if is operated, for example, locking the operation key KB.

The transmitted text processing unit 119 performs a process of storing the input text in the text storage unit 120 and a process of connecting the newly input text to the already input text when the input of the text is switched. Therefore, there is no waste of input. Text storage unit 120
Has a function of storing the input text.

The switch announcement unit 121 has a function of outputting an input switch announcement from the speaker SP via the voice output unit 123 when the setting of the stop flag input from the vehicle state determination unit 117 changes. Specifically, when the vehicle stop flag switches from 0 to 1 (vehicle V
(When it becomes a moving state), the switching announcement unit 121 reads out the text stored in the text storage unit 120 together with the announcement “Switch to voice input”, for example. Therefore, the switching announcement unit 121
It has a voice synthesizing unit, and reads the text while taking the voice synthesizing DB 122 into consideration. Conversely, the vehicle stop flag is 1
From 0 to 0 (when the vehicle V is stopped),
The switch announcement unit 121 announces, for example, "key input is now possible." (Monitor MO
Text is displayed in N). Incidentally, the switch announcement unit 121 corresponds to the "text reading device" in the claims.

The display processing means 13 has a function of prohibiting display by the monitor MON when the vehicle state determination unit 117 sets "1 (moving state)" in the vehicle stop flag. This function corresponds to "display prohibition means" in the claims. When the vehicle state determination unit 117 sets "0 (stop state)" in the vehicle stop flag, the prohibition of the display by the monitor MON is released. Therefore, the vehicle state determination unit 11
The vehicle stop flag 7 is also output to the display processing means 13.

[Operation of Creating Email] Next, the operation of creating an email (method of creating an electronic message) will be described with reference to FIGS.
4 will be described with reference to FIG. FIG. 4 is a flow chart for explaining the operation from the electronic mail creation to the transmission.

First, in S11, the vehicle state determination unit 117 determines whether or not the vehicle is stopped (stopped state). If it is in the stopped state (YES), the text by the key operation input is accepted (S12). At the time of text input by key operation, it is constantly monitored whether or not the vehicle V has moved and whether or not the text input is completed (S13, S14). The text conversion processing is performed by the text conversion unit 112 and the like.

When the vehicle state determination section 117 determines in S13 that the vehicle is moving (moving state), the switching announcement section 1
21 announces switching to voice input. Further, the display by the monitor MON is prohibited (S15). At the time of the switch announcement, the message for switching to voice input is read aloud, and all the text that has already been input is read aloud to prompt voice input (S15). And S
At 16, the text switching unit 118 switches from key operation input to voice input, and accepts text input by voice input. In addition, voice input is performed by the voice / text conversion unit 1.
14 and the like. By making the announcement in this way, the text input can be smoothly switched. Further, by switching the input, it becomes impossible to perform the key operation input, so that the driving operability of the vehicle V can be secured. Of course, the text already input from the operation key KB is utilized by the transmission text processing unit 119, and the newly input text is added to the already input text.

During text input by voice input, it is constantly monitored whether or not the vehicle V is stopped and whether or not the text input is completed (S17, S19). Then, in S17, when the vehicle state determination unit 117 determines that the vehicle is stopped (stopped state), the switching announcement unit 121 issues a switching announcement to the key operation input (S18). At the time of the switch announcement, a message to the effect that text input by key operation is possible is performed, and the text already input is displayed on the monitor MON. And S12
Accepts text input by key operation. This smoothly switches the text input.

If it is determined in S11 that the vehicle is not stopped (NO), since the vehicle V is moving, S
The process moves to 16 to accept voice input. As a result, the key operation input cannot be accepted.

In addition, in S14 when key operation input is performed, or in S19 when voice input is performed.
Then, when the input end processing is performed (YES), S2
The text is moved to 0 and the text that has been input is read aloud (in a configuration not shown in FIG. 3). Then, the creator (for example, the driver of the vehicle V) or the like determines whether or not the input is OK. If not OK (NO), S
Then, the operation shifts to 11 and re-input is performed. On the other hand, if it is OK (YES), it is sent as an electronic mail (S22).
Then, the process ends. By the way, the process of S22 is
The electronic mail creating unit 124, the communication processing unit 12, and the communication device COM perform this.

FIG. 5 shows the contents of the created electronic mail displayed on the monitor. In FIG. 5, the underlined portion shows the key operation input portion with the operation keys KB. Further, the part which is not underlined shows a voice input part by the microphone MC. Of course, the monitor MON is not displayed when the vehicle is moving.

As described above, according to the first embodiment, when the vehicle V is stopped (stopped state), the operability of text input can be improved and the electronic mail can be efficiently created by the key operation ( In case of key operation, you can properly instruct the selection of homonyms and re-segmentation. On the other hand, when the vehicle V is moving (moving state), by voice input, the operability of driving the vehicle V can be improved and an e-mail can be created without hindering the driving. Also, during text creation (entering)
In addition, when there is a change in the vehicle state from stop to movement of the vehicle V or movement to stop, the text input state is appropriately switched. Therefore, the driving operability of the vehicle V is ensured. Also, the display of the monitor MON is switched (inhibition / cancellation of the display), and driving operability is secured from this point as well. By the way, such an electronic mail is rarely a long sentence, and it is considered that most of the short sentences have a small number of characters as shown in FIG. 5, but this electronic mail creating apparatus 10 (creating method) is suitable. You can compose a short email. Of course, a long-sent e-mail can be preferably created. It is not particularly limited whether the transmission OK instruction is given by voice or manual operation, but it is preferable that the instruction is given by voice when the vehicle is moving.
