Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a telephone device, and more particularly to a telephone device, for example, when a call is terminated after greeting the end of a telephone conversation with the other party and the call is suddenly forgotten. The present invention relates to a telephone device with a forget-to-speak function, which is capable of effectively exerting a function when it starts to be said that the service for such a partner can be improved.

[0002]

Background of the Invention and Problems to be Solved By the telephone device, for example, a message such as a customer / business contact is transmitted, and after exchanging a word to end the call, the other party suddenly forgets to speak. Remembering the message, "Oh! then···
In the past, there was often experience that said ".

[0003] For example, if we consider the situation in reverse,
As a matter of fact, when I suddenly remembered such a forgotten message and suddenly became a speaker, I got the situation from the conversation with the other party, and the conversation was over, and after the greetings were ended, And, therefore, usually the result is that the other party is already hanging up (on-hook operation) (or it may be just the moment he hangs up and just hangs up) ! And then ... ”, and you may have had the experience of expressing your willingness to continue the conversation with the other party.

Here, if the last utterance, that is,
If a voice (for example, "Oh! Then ...") from the side indicating the intention to continue the conversation can be heard, relief can be made. As a result, the party trying to hang up will also stop hanging up, as a result of knowing that there is still business (talk), in which case, during the call, such a sudden It is possible to continue a mutual conversation about a matter that you remembered and forgot to say,
Experience shows.

[0005] However, in such a situation, it is not always possible to always secure such a call and return to the conversation state. In some cases, instead of that, the call may be dropped, rather than this.

[0006] That is, after a message such as a customer / business communication is conveyed, and after exchanging the words of terminating the call, the other party suddenly remembers the message that the partner forgot to say. And then ... ", we are already on-hook operation and go on-hook as it is, so the other party hears a busy tone (BT tone) and the call ends. That often happens. Then, when the call is disconnected, the other party needs to give up, "Oh, okay," depending on the business, or else call back. In the latter case, the other party needs to make the call again in order to renew the message that he or she forgets. A technology is conceivable in which a call can be made again if the user goes off-hook during monitoring of a timer for a predetermined time (for example, n seconds) even if the side is on-hook. However, in many cases, the handset cannot be relieved because the handset is released from the ear, and only the voice that was heard during the moment immediately before the release can be recognized (recognized).

[0007] Therefore, it is desirable that, for example, after exchanging the terminology of the call with the other party as described above, even if the on-hook operation is being performed, the other party suddenly remembers the business that he or she forgot to say and speaks to. It is possible to properly respond to the case of starting, avoiding the possibility of disconnecting the telephone beforehand, it is possible to restore the conversation state again without causing the above disadvantages and inconveniences And that the service for the other party can be improved.

[0008] Desirably, even if the user goes on-hook, the above disadvantages and inconveniences do not occur.
Even in such a case, it is possible to appropriately remedy, easily and surely inform the other party that there is still a business, it is possible to restore the conversation state again, and improve the service to the other party That is what you can do.

The present invention has been improved from such a point,
If you can resolve the disadvantages and inconveniences mentioned above and the other party still has a need, you can resume the conversation state again, suddenly remembering the task you forgot to say and began to speak out It is intended to improve the service for such a partner.

[0010] Another object is during and / or during an on-hook operation.
Another object of the present invention is to provide a telephone device which can provide such a service for a predetermined period of time after the on-hook operation and can realize the above.

[0011]

SUMMARY OF THE INVENTION According to the present invention, there is provided a telephone device having a forgotten word prevention function. That is,
The forgetting prevention telephone device of the present invention monitors the presence or absence of the voice of the other party during the on-hook operation, and issues a warning display when the voice of the other party is detected.

[0012] Also, during the timer monitoring after the on-hook, the presence or absence of the voice of the other party is monitored, and when the voice of the other party is detected,
A warning display is issued.

The present invention is also characterized in that during the on-hook operation and during the timer monitoring after the on-hook operation, the presence or absence of the voice of the other party is monitored, and when the voice of the other party is detected, a warning display is issued.

Further, the warning display includes a lamp, a warning sound,
It is characterized by at least one of screen display and vibration.

Further, in the above (claims 1, 2, 3, 4), the state during the on-hook operation is detected by detecting the inclination of the handset after the start of communication.

Further, in the above (claims 1, 2, 3, 4), a state during the on-hook operation is detected by a touch sensor incorporated in the handset.

In the above (claims 1, 2, 3, and 4), the state during the on-hook operation is detected by detecting the inclination of the handset after the start of communication or by detecting a touch sensor incorporated in the handset. It is a feature.

Further, the telephone device is a telephone device that can be used also for mobile communication, and the touch sensor detects that the handset has been released from the ear.

In the above (claims 1, 2, 3, and 4), the voice of the other party is monitored, and the average value level excluding the maximum voice value and the lowest voice value of the other party's voice during a call is stored. During the on-hook operation and during the monitoring of the timer after the on-hook operation, when the sound of the average level is input, the sound is detected.

[0020]

According to the present invention, during the on-hook operation and / or during the timer monitoring for a predetermined time after on-hook (for example, n seconds), the presence or absence of the voice of the other party is monitored, and When a warning is issued, a warning display is issued to alert the user that the partner is still busy (talking), so that the user can be restored to the conversation state again, and the service to the partner can be improved. Becomes Here, in a preferred example, the warning display can be performed in such a manner as to emit at least one of visual, audible, and vibration sensations. For example, one of a lamp, an alarm sound, a screen display, and vibration Alternatively, a combination of two or more of them can be used.

In the present invention, (1) the presence or absence of the voice of the other party is monitored during the on-hook operation,
When the voice of the other party is detected, a warning display (visible, audible, vibratory sensation) is issued, and when the other party is notified that there is still a task, the call can be resumed by a response operation. (2) While monitoring the timer for n seconds after on-hook, monitor the presence / absence of the voice of the other party, and when it detects the voice of the other party, issue a warning display (visible / audible / vibration sensation), and the other party still has a business Is notified, the call can be resumed by a response operation. With this function, a warning display can be confirmed even when a disconnection operation (an operation of turning on a hook switch or pressing a disconnection button with another hand) is performed while holding the handset.
In addition, in the case of a cutting operation using a handset, the time of the above item (1) is further added. (3) The state during the on-hook operation is detected by detecting the inclination of the handset after the start of communication or by a touch sensor incorporated in the handset. Here, in a preferred example, the touch sensor can detect that the touch sensor is separated from the ear. (4) For monitoring the presence / absence of the voice of the other party, the average level excluding the maximum voice value and the lowest voice value of the voice of the other party during the call is stored. During the on-hook operation and during the monitoring of the timer for n seconds after the on-hook, when a sound of the average value level (within + n%) is input, a warning display (visible, audible, vibration sensation) is issued as sound detection. If you suddenly come up with a sound, it utters a little louder than a normal conversation. Therefore, the detection level should be within + n%, and the loud and sudden noise and low sound will be eliminated by excluding the maximum and minimum voice values of the other party's voice. Noise can be prevented.

[0022]

Embodiments of the present invention will be described below with reference to the drawings. 1 and 2 are diagrams showing an embodiment of the present invention. FIG. 1 shows an example of a communication network configuration to which a telephone device according to the present invention can be applied, and FIG. FIG. 2 is a diagram illustrating an example of a device configuration of a telephone device having a forgetting prevention function according to an embodiment of the present invention.

In FIG. 1, reference numeral 100A denotes a telephone device A, which is a telephone device having the device configuration shown in FIG. 2 having a function of preventing forgetting (hereinafter, also abbreviated as the present telephone device, and is referred to in FIG. 2). (Indicated by reference numeral 100). Here, the caller is not limited, and the present telephone device can be used alone (exhibiting functions), so that it is possible to use the present telephone device as well as a call with a general telephone.

That is, in FIG. 1, reference numerals 100B, 1
Telephone devices B, C, D, E, and F, indicated by 00C, 100D, 100E, and 100F, respectively, are denoted by reference numeral 100A.
This shows an example of a connectable form of the present telephone device other than the telephone device A shown by. A telephone G indicated by reference numeral 150 indicates a general telephone (including other terminals).

The telephone devices 100A to 100F and the telephone 150 are connected to, for example, a central office 200, private branch exchanges 310, 315, and 320 through an office line, a dedicated line, and an extension as shown in FIG. Can be configured. Then, in such a communication network, the present telephone device-for example, the telephone device 100A
− Indicates that the other party's voice (regardless of the telephone device 100B to 100F or the telephone G) is monitored during the on-hook operation and, if applicable, for a predetermined time after the on-hook operation Monitoring during the timer monitoring of
When the voice of the other party is detected, an alert is displayed.

For this reason, the telephone device having the function of preventing forgetting according to the present invention is realized here with a device configuration as exemplified in FIG. As shown in the figure, the telephone device 100 (100A to 100F)
Comprises a control device 110 and further includes an internal memory 121
, A data memory unit 122, a clock 123, a call level detecting device 124, and a handset tilt detecting device 125.
, Handset touch sensor 126 and warning indicator 1
27, and these devices are connected to the control device 110. Further, the data memory unit 122 has a call level comparison memory 122a and a timer monitoring memory 122b after on-hook.

The call level detector 124 can be used to monitor the presence / absence of the voice of the other party and detect the voice of the other party, and is a device for detecting the call level of the other party during a call. The detection result is determined by control device 110 and set in call level comparison memory 122a.

The handset tilt detecting device 125 can be used as a means for determining whether or not the on-hook operation of the own device 100 is being performed. The on-hook operation during a call is determined from the tilt of a handset (not shown). Device detects that the handset is tilted more than a certain amount.

The handset touch sensor 126 is also a touch sensor device that can be used as a means for determining whether the on-hook operation of the own device 100 is being performed. That is,
The handset touch sensor 126 is a device for determining that an on-hook operation has been performed during a call based on the fact that the handset has left the ear. The handset touch sensor 126 may be a sensor incorporated in the handset, and includes a state in which the handset is in contact with the ear of the operator of the own device 100 (a state with touch),
Handset removed from ear (no touch)
Can be determined.

Here, the handset tilt detecting device 12
5. The handset touch sensor 126 is used alone or in combination. In the illustrated example, an example in which both are used in combination is shown. In mobile communication such as a mobile phone, the handset touch sensor 126 alone is effective.

The clock 123 is used to monitor the timing of detecting the call level of the other party during the call and to monitor the timer after the on-hook. The control unit 110 makes a judgment, and sets the result in the timer monitor memory 122b after the on-hook.

The warning indicator 127 monitors the presence / absence of the voice of the other party during the on-hook operation and during the timer monitoring for n seconds set as a predetermined time after the on-hook operation. Is used to issue a warning display in order to notify the operator of the own apparatus 100 that there is still a task. Such a warning display:
Preferably, it can be performed by, for example, lamp display, alarm sound display, screen display, or vibration, so that the operator can recognize the warning. Thus, the warning indicator 127 (lamp / alarm sound / screen display / vibration) is displayed during the on-hook operation.
This is a device for displaying a warning (visible / audible / vibration sensation) to the operator when detecting a voice uttered by the other party while monitoring the timer for n seconds after the on-hook. Here, the lamp, the alarm sound, the screen display, and the vibration device can be used alone or in combination.

The control device 110 is a device for controlling each of the above-described devices to realize the function of preventing forgetting. In accordance with a control program stored in the internal memory 121 in advance, control of a sequence as illustrated in FIGS. It can be performed. In this case, it is preferable to monitor the voice of the other party, store the average value level excluding the maximum voice value and the lowest voice value of the other party's voice during a call, and perform the on-hook operation and the timer monitoring after the on-hook. When a sound of the average value level is input, a process can be executed to detect the sound. Hereinafter, a more specific description will be given with reference to FIGS.

[Operation Sequence (During On-Hook Operation
Voice detection)] Figure 3 shows an operation sequence when it detects voice of the other party during a hook operation. In the figure,
The operator (self) on the telephone device side is, for example, “A”,
Assume that the other party is called “Otsu” (this point
The same applies to the following examples). In a call state with the other party (the second party), the telephone device monitors the voice level of the second party (the second party). Here, the operation on the telephone device side (see (a) in the figure) at the time of starting a call may be on either the calling side or the called side.

The monitoring of the voice level of the other party (the second party) during the call state after the start of the call (after the start of the communication) ((b) in the figure) is performed by using the clock 123, the call level detector 124, and the memory unit 122. Under the control of the control device 110,
The average value level excluding the maximum voice value and the minimum voice value of the other party's voice is stored.

During a call, necessary business communication and the like are communicated, and thereafter, it is usual to greet each other (A and B) and hang up. When the on-hook operation of the own side (the instep side) is detected, the presence or absence of the voice of the other party is monitored. During the on-hook operation ((c) in the figure), release the handset from the ear or
The handset can be detected by tilting and / or a combination of both, based on information from the handset tilt detector 125 and / or the handset touch sensor 126.

Here, if the other party (Otsu side) recalls the message that the user forgot to say after trying to perform the disconnection operation after greeting the end of the call, "A! Then ”. Then, the telephone apparatus displays a warning by voice detection. Here, the warning display ((d) in the figure) is based on a lamp, an alarm sound, a screen display, and vibration alone or in combination. That is, when the telephone apparatus is in the on-hook operation state, the other party suddenly remembers the business that he or she forgot to say. Then, if you say a word (voice) that says something like "
The voice of the other party is detected, and a warning display (visible / audible / vibration sensation) is issued by the warning display 127.

The operator (A) issues a warning display (visible, audible,
By recognizing the vibration sensation, it is known that the other party (B) still has a task, and the call can be resumed by a response operation ((E) in the figure). That is, by recognizing the warning and performing a response operation (contacting the handset with the ear or returning the handset tilt, and a combination of both),
The operator (A) who was on-hook operation can restart the call with the other party (Otsu) again by uttering words such as "Hello!" Without hanging up the telephone. Thus,
When returning to the call state with the other party (Otsu side), the telephone device
Monitor the voice level of the other party (B) again.

As described above, during the on-hook operation, the presence or absence of the voice of the other party (the second party) is monitored, and when the voice of the other party (the second party) is detected, a warning is displayed, and the other party (the second party) still has a business. The call can be resumed by the response operation by the notification of the notification. In comparison with the case of the conventional device not employing the present invention, in this case, the user (the instep side) has already been engaged in the on-hook operation (see FIG. 3 (c)), and the on-hook operation is continued as a result. It often happens that (B) hears a busy tone (BT tone) and the call is disconnected, and the other party (B) needs to make a call again depending on the situation. This can be avoided. This telephone device monitors the presence of voice of the other party (B), and when the other party (B) utters a sound, issues a warning display to notify the other party (B) that there is still use (talk). Since the user is alerted, it is possible to restore the conversation state again, and the service to the other party (the second party) is improved.

The state during the on-hook operation can be detected by detecting the inclination of the handset after the start of communication or by a touch sensor incorporated in the handset. In addition, the monitoring of the presence / absence of the voice of the other party (the second party) can be performed based on the average level of the other party's (the second party) voice excluding the maximum voice value and the lowest voice value during the call. During the on-hook operation as described above, when a sound of an average value level (within + n%) is input, the sound is detected as a sound.
A warning display can be issued ((d) in the figure). As described above, when suddenly coming up, a louder voice is generated than in a normal conversation. Therefore, the detection level is set within + n%, and the maximum and minimum voice values of the other party's voice are excluded. The effect of sudden noise and continuous low noise can also be prevented, and this function can be more effectively exerted.

[Operation Sequence (On Hook Operation, On
Hook (cut) voice detection after)] Figure 4 shows an operation sequence in a case where hook operation, and detects the voice of the other party after hook (disconnected). FIG. 4 shows a case where the voice detection is performed while the timer is being monitored for n seconds after the on-hook operation (cut off), further proceeding from the on-hook operation. (This point is the same in the following example). Hereinafter, the main part in this operation sequence will be described.

In a call state (either on the outgoing or incoming call side) with the other party (the second party), the telephone apparatus monitors the voice level of the second party (the second party) ((a), (b) in the figure). ). When the telephone device detects that the on-hook operation is performed on its own side (the instep side) ((c) in the figure), it monitors the presence of the voice of the other party (the second party).

When the telephone apparatus detects the on-hook (disconnection) of its own side (the instep side), it monitors the existence of the voice of the other party (the second party) during monitoring of the timer for n seconds ((a) in the figure). Thus, even during the timer monitoring for n seconds after the on-hook,
Monitors the voice of the other party (B). When the telephone device is in a timer monitoring state for n seconds after on-hook (disconnection),
Remembering the task that the other party suddenly forgot to say, "Ah! Then, the telephone device detects the voice of the other party (B) and displays a warning (visible / visible).
It emits audible and vibrational sensations ((d) in the figure). When the operator (A) recognizes the warning display (visible / audible / vibration sensation), he / she knows that the other party (B) still has a task.
The telephone call can be resumed by a response operation (contact of the handset with the ear or return of the handset tilt and a combination of both) ((e) in the figure). When returning to the communication state with the other party (the second party), the telephone device monitors the voice level of the second party (the second party) again.

In the case of FIG. 4, the on-hook (disconnect) following the on-hook operation is further detected so that the voice of the other party (the second party) is detected. Monitors the other party's voice for sound,
Warning display (visible / audible /
By issuing a vibration sensation and notifying the other party (B) that there is still a task, the call can be resumed by a response operation. Therefore, it is possible to obtain the same effects as in the case of the above-mentioned section “Operation sequence (other party voice detection during on-hook operation)”. Even if our side goes on-hook, if we go off-hook during the timer monitoring for a predetermined time, we can talk again.In that case, we will remove the handset from the ear, so for a moment before releasing it Since only the voice heard by the user can be conscious (recognized), it cannot be remedied in many cases. However, even if the telephone device goes on-hook, the other party's voice is checked while monitoring the timer for n seconds after on-hook. Monitor, and when the other party speaks,
By issuing a warning display (lamp / alarm sound / screen display / vibration), the other party (B) is alerted that there is still use (talk), so it is possible to restore the conversation state again. , And the service to the other party (B) will be improved.

[Operation Sequence (After On Hook (Disconnect))
The voice detection)] FIG. 5, shows the operation sequence when it detects voice of the other party after hook (cutting),
This is the case where the state during the on-hook operation does not pass. In the following, the main part will be described. In a call state (both outgoing and incoming sides are possible) with the other party (the second party), this telephone device monitors the voice level of the second party (the second party) as in FIGS. ((A), (b) in the figure).

When the operator (A) performs a disconnection operation (for example, an operation of turning on the hook switch or pressing the disconnection button with another hand) while holding the handset, for example, the telephone apparatus of the present invention (A). Side) on-hook (cut)
Is detected, the presence or absence of the voice of the other party (B) is monitored during the timer monitoring for n seconds ((a) in the figure).

When the telephone device is connected to the n
In the state of monitoring the timer for 2 seconds, the other party (Otsu) suddenly remembers the task that he forgot to say, and said, "Ah! Then, if you say a word (voice) that says a message, the telephone device will
And a warning display (visible, audible, vibration sensation) is issued ((d) in the figure). When recognizing the warning display (visual, audible, vibrational sensation), the repeater knows that the other party (B) still has a task, and thus performs a response operation (contacts the handset with the ear or returns the handset tilt). And a combination of both) can resume the call. When returning to the communication state with the other party (the second party), the telephone device monitors the voice level of the second party (the second party) again.

As shown in FIG. 5, the present embodiment can cope with the case where the on-hook operation is not performed. During the monitoring of the timer for n seconds after the on-hook operation, the other party (the second party) is monitored for the presence or absence of the voice. Warning display (visible /
When the other party (the second party) is notified that there is still a task, the call can be resumed by a response operation, and the [operation sequence] shown in FIGS.
In addition to the same effects as in the case of the above item, the warning display can be confirmed even if the disconnection operation (the hook switch on or the depression button pressing operation with another hand) is performed while holding the handset by this function ( In the case of the disconnection operation by the handset, the time of the above-mentioned section [Operation sequence (other party voice detection during on-hook operation)] is added.)

FIG. 6 shows an example of a control flow of the telephone device according to the present invention having a function of preventing forgetting. The control device having the configuration shown in FIG. 2 controls the sequence shown in FIGS.

In this example, the process comprises steps S1 to S10. In step S1, it is determined whether or not the vehicle is in an off-hook state. As a result, if the answer is negative (N), it is determined that disconnection is being performed, while if the answer is affirmative (Y), it is determined that the telephone has been switched from the off-hook state, that is, the disconnection to the busy state, and the control device 110 Step S as if
A series of processes from 2 to S10 is started. Here, such off-hook may be caused by either the case of the calling side or the case of the called side.

In step S2, the voice level of the other party is monitored. Here, the average value level excluding the maximum voice value and the minimum voice value of the partner voice is stored.

In step S3, it is determined whether or not the vehicle is in an on-hook operation state. Here, it is assumed that the judgment is made by separating the handset from the ear or tilting the handset, or a combination of both (one of them is always necessary), and FIG. 7 shows an example of the content of the on-hook operation state judgment processing. It is.

Referring to FIG. 7, in the present example, first, in step S31, it is checked whether "no setting" or "setting exists" for the inclination detecting device 125, and if "setting exists", furthermore, in step S32, The inclination detection is checked, and if the inclination detection is “present”, it is determined that the on-hook operation is being performed. On the other hand, in step S31, "no setting"
Or if the tilt detection by the tilt detection device 125 is "no" in step S32, the process further proceeds to step S33, where "no setting" or "no" is set for the touch sensor (126) device. Check if there is any setting. If it is "set" in step S33 and if "no touch" is found as a result of checking whether the sensor information is "touched" or "no touch" in step S34, it is determined that the state is the on-hook operation state. Otherwise, it can be determined that the call is still in progress without setting the terminal to the on-hook operation state.

Returning to FIG. 6, if the answer in step S3 is negative, the monitoring process in step S2 is repeated. If the answer is affirmative, the process proceeds to the next step S4 to monitor the other party's voice. here,
If there is no voice, step S5 is skipped, but if there is voice, the control device 11
A value of 0 indicates that a warning is displayed upon detection of the voice of the other party. Here, the warning is based on a single or a combination of a lamp, a warning sound, a screen display, and a vibration (one of them is necessarily required), and FIG. 8 shows an example of the content of the warning display process.

The warning display can be performed by lamp display by a lamp, warning sound display by a warning sound device, screen display by a screen display device, and vibration by a vibration device. In FIG. 8, in the present example, first, in step S51, it is checked whether the lamp is "no setting" or "present". If "present", a warning display (lamp display) is made in step S52, and so on. If not, the step S
52 is skipped. Next, in step S53,
Similarly, for the alarm sound device, it is checked whether “not set” or “present”. If “present”, a warning display (warning sound display) is made in step S54. Skip, and then, in step S55, "No setting" or "Yes" for the screen display device.
Is checked, and if "Yes", a warning display (screen display) is made in step S56. Otherwise, step S56 is skipped. In step S57, "No setting" is set for the vibration device. Is checked, and if "Yes", a warning display (vibration) is displayed in step S58.
58 is skipped.

Returning to FIG. 6, in step S6, it is determined whether or not the terminal is in an on-hook (disconnection) state. As a result, if the answer is negative, the process returns to step S3; if the answer is affirmative, that is, on-hook (disconnection) If so, the process proceeds to step S7
Proceed to.

In step S7, the on-hook change is checked, and if the result of the determination is "change", step S8 is selected, and a timer is set for n seconds at the timing.
On the other hand, in the case of “continuation”, step S8 is skipped and the process proceeds to the next step S9.

In step S9, the timer set as described above is monitored, and whether or not a timeout has occurred is checked, and it is determined whether or not the timer is being monitored for n seconds after on-hook. If the answer is negative, the process returns to step S3, during which the above process can be repeated, and when a timeout occurs, control device 110 can execute the disconnection operation at that timing.
