Description

  The present invention relates to a technology of a telephone device that defines a procedure for executing an incoming call for telephone communication.

Recently, nuisance calls aimed at fraudulent misconduct and exploitation of money have been frequently used by telephones to deceive mischievous relatives and have become a social problem.
In addition, such a nuisance call may be easily deceived and cause a great deal of damage if it is targeted by an elderly person or a socially weak person whose judgment has declined.

For this reason, as shown in Patent Document 1, register a nuisance call so as not to receive a call, or register a call destination such as a family, and if there is a request for an incoming call from the registered call destination, A technology for displaying such information has been developed.
JP-A-9-107398

  However, the conventional technology can prevent incoming calls from being made when a nuisance call is repeated, and can identify calls from family members. For a person, these functions alone are not sufficient, and it may be possible to respond to an incoming call request inadvertently. As a result, it can be deceived or unpleasant.

  Therefore, the present invention provides a telephone device that can perform incoming calls only to registered destinations such as family members and welfare personnel by only sounding an answer or applause when an incoming call is received. It is an object of the present invention to provide a technique capable of preventing an inadvertent telephone response from being performed.

It is another object of the present invention to provide a telephone device that can provide the function of a normal telephone device as it is for a telephone call from a destination other than the registered destination.
In addition, even for elderly people and those with poor judgment, there is an environment where only telephone calls from registered destinations can be reliably received just by habitually responding to phone calls each time. The aim is to create a habit of the procedure that does not receive annoying calls, while providing extremely low attention required when answering a call.

  As a means for solving the above-mentioned problem, the telephone device of the invention of claim 1 is a telephone device that defines a procedure for executing an incoming call communication from a specific destination, and the identification information of the specific destination in advance. Identification information registration means for registering, incoming call request detection means for detecting an incoming call request signal for requesting an incoming telephone call, and when the incoming call request detection means detects the incoming call request signal, Identification information detection means for detecting the identification information of the destination concerned, identification information registration judgment means for judging whether the identification information detected by the identification information detection means is registered in the identification information registration means, Ringing sound output means for outputting a ringing tone for incoming call communication, sound detection means for detecting sound, and sound information for preregistering sound information based on sound detected by the sound detection means Whether the sound information based on the sound detected by the sound detection means is registered in the sound information registration means when the recording means and the identification information registration determination means determine that the identification information exists. When it is determined that the acoustic information is registered by the acoustic information registration determination unit and the acoustic information registration determination unit to determine, the incoming of the telephone communication for which the incoming call request has been made is executed, The gist of the present invention is to include call execution means for setting a call state.

  As a result, when the telephone device receives an incoming call request by the incoming call request signal, the incoming call sound output means outputs the incoming call sound of the telephone communication. When this ringing tone is output, it is possible to know that there is a request for incoming telephone communication. In this way, when a request for incoming telephone communication is notified, for example, incoming telephone communication such as pressing the reception button or on-hook is executed. However, such incoming telephone communication is executed. If left unattended, it will not be in a talking state with the callee. Further, when an incoming call is executed according to the ringing tone, a call state is established with the callee.

  In addition, when the incoming request detection means detects the incoming request signal, the telephone apparatus registers in advance the identification information of the destination related to the detected incoming request signal in the identification information registration means by the identification information registration determination means. Judgment will be made.

  If it is determined that the sound information has been registered in advance, the sound information registration determination means determines whether the sound information based on the sound detected by the sound detection means has been registered in the sound information registration means. Here, if it is determined that it is registered, the call execution means executes an incoming call for the telephone communication requested to be received, and a call state is established with the callee.

  In other words, when there is a ringing tone to notify the request for incoming telephone communication, for example, the answering button can be used by simply replying to the sound registered in advance in the sound information registering means, for example, “Yes”. The telephone call is executed without pressing or on-hooking, and the call destination is connected to the call destination.

  Further, the determination by the acoustic information registration determination means is, for example, acoustic information registered in advance in the acoustic information registration means and acoustic information based on the sound detected now (which is the sound detected in real time). , Based on the degree of difference or the same degree. Therefore, for example, it is determined that the person who has previously registered the sound in the acoustic information registration means is the same as the person who has made the sound now, or the person who has registered in advance, Now, even if the person who made the voice is different, if it is the same word, for example, “Yes”, it is judged that it is registered, or a part of the pre-registered word is Now, when it is detected as voice, it can be determined that it is registered. This is a design item regarding the determination accuracy and a setting item.

  Therefore, when a ringing tone requesting an incoming telephone call sounds, just replying in the same way as the sound registered in advance in the sound information registering means, and only the specific destination registered in advance Incoming calls can be executed. In addition, in response to a request for incoming call communication from a destination other than a specific destination that has been registered in advance, it is possible to obtain an incoming call communication procedure in which the incoming call is not executed simply by replying. .

The telephone device according to a second aspect of the present invention is summarized as the telephone device according to the first aspect, wherein the identification information is a telephone number.
As a result, the telephone apparatus has the same operation as that of claim 1 and, when the incoming request detection means detects the incoming request signal, the identification information registration judgment means causes the destination related to the detected incoming request signal. Is previously registered in the identification information registering means.

  That is, the identification information registration means is determined based on the telephone number. By this, when there is no notification of the telephone number or when the notified telephone number does not match the telephone number stored in advance in the identification information registration unit, the subsequent execution of the acoustic information registration determination unit is not performed, As a result, depending on the call execution means, the incoming call is not executed.

Accordingly, the registration contents of the identification information registration means that influences the execution of the incoming call communication by the call execution means becomes the telephone number, and the registration work is simplified.
According to a third aspect of the present invention, when the identification information registration determining means determines that the identification information is registered, the telephone sound output means outputs a ringing sound reflecting the identification information. The telephone device according to claim 1 or 2, wherein

  As a result, the telephone device of claim 3 has the same operation as that of claim 1 or claim 2, and the ringing tone is a specific transmission related to the identification information previously registered in the identification information registration means. Reflects that the request is for an incoming call.

  Therefore, it is possible to understand that it is a telephone communication from a family member or a welfare person who has been registered in advance simply by listening to the ringing tone, and for example, an incoming call is executed simply by answering “Yes”. This makes it possible to execute incoming calls without worrying about nuisance calls from strangers.

  4. The telephone device according to claim 4, wherein the sound information is information based on a frequency component of sound detected by the sound detecting means. The gist is a telephone device.

  As a result, the telephone device of claim 4 has the same operation as that of claims 1 to 3, and in addition, the sound information registration determination means makes a determination based on the sound information based on the frequency component of the sound. For example, it is possible to utilize a voiceprint analysis method for detecting the distribution state of frequency components in the determination of the presence / absence of registration by the acoustic information registration determination means.

  Therefore, for example, it is possible to use a voiceprint match state or difference state for determination, and it is possible to determine whether the sound is a sound or a sound with a high degree of accuracy that can identify an individual or a man and woman. A judgment with a high degree of discrimination becomes possible.

  According to a fifth aspect of the present invention, there is provided a telephone device that outputs a reception sound of the telephone communication, a transmitter that inputs a transmission sound of the telephone communication, the receiver, the transmitter, and the identification information. Registration means, said incoming request detection means, said identification information detection means, said ringing tone output means, said acoustic detection means, said acoustic information registration means, said acoustic information registration judgment means, and said call execution means A plurality of electrodes attached to the casing, a conduction state detecting means for detecting a conduction state between the plurality of electrodes, and a conduction state detected by the conduction state detection means, A determination accuracy that reduces the accuracy of determination by the acoustic information registration determination means when it is determined by the conduction state determination means that determines whether the resistance value is equal to or less than a predetermined resistance value or less than a predetermined resistance value by the conduction state determination means. Decline And gist telephone device according to any one of claims 1 to 4, characterized in that it comprises a stage.

  Thus, the telephone device of the invention of claim 5 has the same operation as that of claims 1 to 4, in addition to the receiver, transmitter, identification information registration means, incoming request detection means, Conduction state between a plurality of electrodes attached to a housing that accommodates identification information detection means, ringing tone output means, acoustic detection means, acoustic information registration means, acoustic information registration determination means, and call execution means Is detected by the conduction state detection means, and it is judged by the conduction state judgment means whether the conduction state is equal to or less than a predetermined resistance value. However, the accuracy of judgment by the acoustic information registration judgment means is reduced.

  Due to the decrease in the determination accuracy, for example, the threshold for determining that the detected acoustic information is stored in the acoustic information registration unit in the determination of the presence or absence of registration by the acoustic information registration determination unit is lowered and stored. It takes less time to determine that

  For example, if it is not determined that the registration has been made until the entire answer “Yes” is detected before the judgment accuracy is lowered, after the judgment accuracy is lowered, “ It is possible to determine that it has been registered only by detecting a part of "". Or, if it is not judged that it was registered until the whole of “Yes” is detected before the judgment accuracy is lowered, the voice “h” is detected after the judgment accuracy is lowered. Sometimes, it is possible to determine that the user has been registered when detecting “Yes” in a reply made by a person different from the registrant. In this case, the deterioration of the determination accuracy is a design item or a setting item to be selected as appropriate.

  Therefore, for example, when the case is placed on an object or placed in a pocket, it is determined that the electrical connection between the electrodes exceeds the specified resistance value, and the case is held by hand. By setting so that the conduction state between the electrodes is determined to be less than the predetermined resistance value, it is possible to control increase / decrease in the determination accuracy according to whether the housing is held by hand Become.

  As a result, when the case is held by hand, for example, an incoming call is performed simply by making a sound such as “ha” or sound such as a tongue hitting, and when the case is in a pocket, It is possible to prevent the incoming call from being executed until all of the “yes” answers have been issued.

  As a result, for example, when the case is put in a pocket or the like without being held by hand, it is possible to prevent the incoming call from being accidentally performed due to the sound of the case being worn by clothes or surrounding sounds. If you have it in your hand, you can make the incoming call when you detect the minimum sound that can confirm your willingness to do it, for example, “ha”, It is possible to define a procedure for executing an incoming call reflecting the actual usage state of the cellular phone device to be operated.

  According to a sixth aspect of the present invention, the determination accuracy reducing means shortens a sampling period when the acoustic information is created from the sound detected by the acoustic detection means, so that the determination by the acoustic information registration determination means is performed. The gist of the telephone device according to claim 5, wherein accuracy is lowered.

  As a result, the telephone device of the invention of claim 6 has the same operation as that of claim 5, and the decrease in the accuracy of the judgment by the acoustic information registration judgment means causes the acoustic information to be obtained from the sound detected by the acoustic detection means. This is done by shortening the sampling period when creating.

  Accordingly, the degree of coincidence or difference between the pieces of acoustic information is determined based on the acoustic information obtained in a short sampling period, and as a result, the number of comparison points is reduced and the judgment accuracy is lowered.

  The telephone device according to claim 1 can execute an incoming call only from a specific destination registered in advance only by answering when a ringing tone for requesting an incoming telephone communication sounds. When a ringing tone is heard for a request for an incoming call from a destination other than a specific destination that has been registered in advance, a procedure for receiving an incoming call without performing the incoming call is obtained. In addition, it is possible to receive calls only from a registered destination such as a family member by simply replying at the same time. It is not possible to connect only by itself, and it is possible to provide only a connection function by on-hook of a normal telephone device.

  As a result, it has a function of connecting a telephone by on-hook of a normal telephone device, and when an incoming call is received, it only sounds a sound such as a reply or applause, and a family or welfare person who has been registered in advance A telephone device that can only receive incoming calls is provided, and it is possible to provide a technology that can prevent the inadvertent execution of incoming calls saying that it will casually go on-hook, This technology has an extremely excellent effect that it is possible to provide a high nuisance call rejection function.

  In addition, even for elderly people or those with poor judgment, just answering the call in the same way every time you make a call, make sure that only phone calls from registered destinations are received. An environment is provided in which

  As a result, it is only necessary to reply in the same way at any time, so the attention required for answering the phone can be extremely low, and the procedure that does not inadvertently perform incoming calls of unwanted calls It becomes possible to create habits, and it has an excellent effect that the function of eliminating nuisance calls is effectively utilized for the elderly and those who have reduced judgment.

  The telephone device according to claim 2 has the same effect as that of claim 1, and the registration content of the identification information registration means that determines the execution of the incoming call communication by the call execution means becomes a telephone number. Since this is simple and clear, there is an extremely excellent effect that the registration work of the destination for enabling the incoming call communication by sound can be performed with less man-hours and without a doubt.

  The telephone device according to claim 3 has the same effects as those of claim 1 or claim 2, and can be understood to be telephone communication from, for example, a family member or a welfare person only by listening to the ringing tone. At the same time, for example, you can understand that an incoming call is executed simply by answering “Yes”, and you can safely execute the incoming call without doubting that it is a nuisance call from a stranger. Therefore, it is possible to make the nuisance call rejection function more reliable.

  The telephone device according to claim 4 has the same effects as those of claims 1 to 3, and can use, for example, the matching state and the difference state of voiceprints for the determination of individual identification and gender. It is extremely excellent that it can provide a high degree of freedom in design, such as being able to judge with a high degree of accuracy so that it can be identified, or a judgment with a high degree of discrimination that can distinguish whether it is a sound or a sound. Has an effect.

  The telephone device according to claim 5 has the same effects as those of claims 1 to 4, and, for example, when the case is put in a pocket or the like without holding the case by hand, the case is put on clothes. If the incoming call is not mistakenly executed by a passing sound or surrounding sounds, and the case is held by hand, the minimum sound that can confirm the intention to execute the incoming call, for example, “ha” It is possible to execute an incoming call when a voice such as a voice signal is detected. For example, a procedure for executing an incoming call reflecting the actual use state of a mobile phone device or the like can be defined, and high practicality is provided. There is an extremely excellent effect that it becomes possible.

  In addition to having the same effect as that of the fifth aspect, the telephone device according to the sixth aspect determines the degree of coincidence or difference between the acoustic information based on the acoustic information obtained in a short sampling period. Therefore, the minimum sound that can confirm the intention to properly execute the incoming call, for example, when holding the housing by hand, the incoming call will be detected when the voice is detected such as “ha” When the case is put in a pocket, etc., it is possible to make a judgment with high accuracy over a long period of time so that incoming calls are not mistakenly executed. Thus, an extremely excellent effect is achieved that a configuration providing high practicality can be easily realized.

Next, an embodiment of the invention will be described.
FIG. 1 is an explanatory diagram of a usage state of the telephone device 1, and FIG. 2 is a block diagram of the telephone device 1. As shown in FIG. 1, the telephone device 1 includes a rectangular box-shaped casing 3, a display 5 attached to the operation side 4 of the casing 3, and an operation button unit 7 arranged alongside the display 5. A speaker 9 that outputs a reception sound and a ringing tone, a microphone 11 that detects a transmission sound and a reply sound, an indicator lamp 13 that displays a request for an incoming call, and a connector unit 15 that performs power supply and external input / output And a ring 17 for attaching the hanging strap 19 of the housing 3 and electrodes 25 and 27 attached to the adjacent sides 21 and 23 of the operation side 4 of the housing 3.

The operation button unit 7 includes a call button 31, a cut button 33, and a numerical symbol button 35.
As shown in FIG. 1, when the operation side 4 of the housing 3 is opened and the housing 3 is held by the hand 37, the two electrodes 25 and the electrode 27 are formed by the hand 37. It is provided on the adjacent sides 21 and 23 in a position where it comes in contact with the fingers and the flat surface of the finger. As a result, when the user tries to use the telephone device 1 and holds the housing 3 with the hand 37, the resistance value between the electrode 25 and the electrode 27 rapidly decreases and falls below a predetermined resistance value.

  As shown in FIG. 2, the telephone device 1 includes an antenna 41 for performing wireless communication with a public wireless telephone network (not shown) and a wireless telephone unit 43 connected to the antenna 41. Type radio telephone apparatus. Although the detailed illustration of the configuration of the portable radiotelephone device is omitted, any configuration may be used as long as it can receive incoming calls.

The wireless telephone unit 43 includes a RAM 45 that provides a function of a known microcomputer that performs various processes, a CPU 47, and a ROM 49.
The radio telephone unit 43 having such a configuration includes an input of sound from the microphone 11, an output of sound to the speaker 9, a display on the display 5, an input of operation to the operation button unit 7, and an indicator lamp A well-known wireless telephone function is provided by controlling the lighting state of 13 by the CPU 47 or the like.

For example, when an incoming call request signal is received via the antenna 41, the indicator lamp 13 is turned on and a ringing tone is output by the speaker 9.
In this case, when the operation of the call button 31 (see FIG. 1) is detected, the incoming call is executed, the received sound is output from the speaker 9, and the transmitted sound is input from the microphone 11.

  If an operation of the call button 31 is detected without receiving an incoming call request signal, then an operation of the numerical symbol button 35 (see FIG. 1) is detected, and this operation is performed according to a predetermined rule. For example, in the case of a telephone number, transmission using the telephone number is executed. When it is detected as a result of the call that an incoming call has been executed by the call destination, a telephone call is started between the speaker 9 and the microphone 11.

When the operation of the off button 33 (see FIG. 1) is detected in the state of a telephone call by outgoing call or incoming call, the call state is terminated.
The telephone device 1 has the following configuration in addition to the functions of the known telephone device described above.

The two electrodes 25 and 27 are connected to a touch detection circuit 39 as shown in FIG. The touch detection circuit 39 is connected to the radio telephone unit 43.
When the resistance value between the electrodes 25 and 27 exceeds a predetermined value, that is, when the telephone device 1 is not held by the hand 37, the touch detection circuit 39 sends a touch detection rejection signal (high state) to the wireless telephone unit. When the resistance value between the electrodes 25 and 27 is equal to or less than a predetermined value, that is, when the telephone device 1 is held by the hand 37, the touch detection circuit 39 outputs a touch detection signal (low state). Output to the radio telephone unit 43.

As a result, the CPU 47 included in the wireless telephone unit 43 can use information regarding whether or not the telephone device 1 is held by the hand 37.
On the other hand, the microphone 11 for detecting the transmitted sound is directly connected to the radio telephone unit 43, and an analog signal processing unit having a digital filter for extracting the intensity of a predetermined frequency component after converting the analog signal into a digital signal. 51 is connected.

  For example, the analog signal processing unit 51 adjusts the level of the sound input from the microphone 11 to a predetermined value, converts it to digital data at a predetermined sampling frequency, and performs a band-pass filter process on the 200 Hz to 2000 Hz band in 100 Hz increments. , It has a function of outputting every 0.1 second whether there is a signal in the band. With respect to this function, various commonly used methods can be used, and detailed description thereof is omitted.

  By having such a function, the analog signal processing unit 51 explains the output for each frequency band in FIG. 3, for example, when the voice “A” is input for 0.1 seconds from time t1 to time t2. As indicated by an instruction 53 in the figure, for example, “1” indicating that a signal is detected for each band, such as “1” for the bands 200 Hz and 300 Hz, “0” for the bands 400 Hz and 500 Hz, or the signal "0" indicating that no is detected is output.

A so-called voiceprint waveform is obtained by graphing the presence or absence of a signal for each band as time passes.
The radio telephone unit 43 includes an application card socket 55 shown in FIG. 2, and has a configuration in which an application memory 57 storing application software can be used.

  With this configuration, by storing application software as will be described later in the application memory 57, the application software can be activated and executed.

An example of the application software will be described below.
4 is a flowchart of an automatic reception target registration processing routine activated by the CPU 47 at predetermined intervals, FIG. 5 is a flowchart of an automatic reception processing routine for elderly people, FIG. 6 is a flowchart of an automatic incoming number registration processing routine, and FIG. Is a flowchart of the feature extraction processing routine, FIG. 8 is a flowchart of the search processing routine for the registration feature corresponding to the extracted feature, and FIG. 9 is a search process for 2 seconds after the registration feature corresponding to the extracted feature is output. It is a flowchart of a routine.

First, the automatic reception target registration process will be described with reference to FIG.
When the automatic reception target registration process is started by the CPU 47, first, a push button operation input is performed (S100), and then it is determined whether or not there is a push button operation for instructing an automatic listener registration operation. It is determined whether a registration operation has been performed (S200). Note that the push button operation for instructing the automatic speaker registration operation is a design matter for operating the numerical symbol button 35 in a predetermined procedure.

Here, if it cannot be determined that there has been an automatic speaker registration operation (S200), the automatic reception target registration processing routine is once terminated.
On the other hand, if it can be determined that there has been an automatic speaker registration operation (S200), a registration start message is first output to the display 5 and the speaker 9 (S300), and then the sound detected by the microphone 11 is detected. Is input through the analog signal processing unit 51, and a response sound capturing process is performed (S400). As described above with reference to FIG. 3, the data for each frequency band of 0.1 seconds of sound detected by the microphone 11 is input by this answering sound capturing process.

  Next, a feature extraction process is performed to extract the characteristics of the data for each frequency band read in the reply sound capturing process (S500), and the extracted features (time-series frequency distribution) are automatically received in the application memory 57. A storage process for writing into the target feature storage area 59 (see FIG. 2) is performed (S600).

  In the feature extraction process in S500, as shown in FIG. 7, first, data for each frequency band input in the answer sound capturing process in S400, for example, data as shown in the instruction 53 of FIG. 3 is input (S510). ), A frequency distribution extraction process for extracting the frequency band “1” indicating that the signal has been detected is performed (S520), and the extracted frequency distribution is temporarily stored in time series (S530). . This feature extraction process (S500) is called as a subroutine and executed as appropriate.

  This process is continued until it is determined that two seconds have passed from the sound capturing process for answering in S400 to the storing process in S600 (S700). That is, sampling for extracting and storing the acoustic features for 2 seconds is performed. For 2 seconds, after confirming the output of the registration start message in S300, it is assumed that the voice for registration, for example, “high-high” is uttered, and extraction of features such as “high-high” is ensured. It is the time required for The 2 seconds are design values.

For example, by performing the sampling for 2 seconds, data for each frequency band obtained by sampling “HIGH” every 0.1 seconds can be obtained.
After completion of the measurement for 2 seconds in S700, a confirmation message for starting the next registration is displayed on the display 5 (S800). Subsequently, there is a push button operation for requesting the start of the next registration, or the start of the next registration is not requested. It is determined whether there is a push button operation (S900). Note that the push button operation for requesting the start of the next registration and the push button operation not requiring the start of the next registration are design matters for operating the numerical symbol button 35 in a predetermined procedure.

  If it is determined that the next registration is requested (S900), the process of outputting the registration start message in S300 is repeated. If it is determined that the next registration is not requested (S900), the automatic reception target registration is performed. The process is temporarily terminated.

With the automatic reception target registration process described above, the voice characteristics of the user who uses the telephone device 1 for automatic reception can be registered.
Next, an automatic incoming call number registration process for registering an automatic incoming call target telephone number will be described with reference to FIG.

  When the automatic dialing number registration process is started every predetermined time by the CPU 47, first, a push button operation input is performed (S1000), and then it is determined whether or not there is a push button operation instructing the automatic dialing number registration process. Then, it is determined whether there has been an automatic incoming call number registration processing operation (S1100). The push button operation for instructing the automatic incoming call number registration processing operation is a design matter for operating the numerical symbol button 35 according to a predetermined procedure.

If it cannot be determined that there has been an automatic incoming call number registration processing operation (S1100), this automatic incoming call number registration processing routine is once terminated.
On the other hand, if it can be determined that there has been an automatic incoming call number registration process operation (S1100), a registration number input process for detecting the operation state of the numerical symbol button 35 is performed (S1200), which means execution of predetermined registration. Registration is determined by determining whether or not the operation of the numerical symbol button 35 has been performed (S1300). If it is determined that registration is to be performed, the operation state of the numerical symbol button 35 is subsequently set to the application memory 57. The automatic incoming call number storage area 61 (see FIG. 2) stores the automatic incoming call number registration process (S1400). On the other hand, if the registration cannot be determined, the automatic incoming call number registration process (S1400) is executed. In step S150, it is determined whether or not the operation of the numerical symbol button 35 meaning the end of registration has been performed. ).

  If it is determined that the process is terminated (S1500), the automatic incoming call number registration process is temporarily terminated. If it is not determined that the process is terminated (S1500), the registration number input process (S1200) or the termination determination ( S1500) is repeated.

The automatic incoming number registration process described above enables registration of telephone numbers for automatic incoming calls, such as family telephone numbers and welfare related telephone numbers.
Next, a usage example of the telephone device 1 that has performed the above-described automatic reception target registration processing and automatic incoming number registration processing will be described.

  When the radio telephone unit 43 receives the incoming call signal via the antenna 41, the automatic reception process for the elderly shown in FIG. 5 is started by the CPU 47. First, the housing 3 is moved from the state of the resistance value between the electrodes 25 and 27 to the hand 37. The touch detection signal input process is performed to input the output of the touch detection circuit 39 used to determine whether the touch detection signal is held (S2000). It is determined whether there is no touch when a signal is input (S2100). If it is determined that there is a touch, that is, if the housing 3 is held by the hand 37, then a process of setting a touch flag in the touch flag setting area 63 (see FIG. 2) of the application memory 57 is performed. On the other hand, if it is determined that there is no touch, that is, if the housing 3 is not held by the hand 37, the next incoming call is performed without performing the touch presence flag setting process (S2200). Number detection processing is performed (S2300).

In this incoming call number detection process, the incoming call number included in the incoming call signal input via the antenna 41 is extracted by a predetermined method.
Here, after performing the incoming call number detection process, it is determined whether or not the detected incoming call number is registered in advance in the automatic incoming call number storage area 61 in the process of S1400 described above (S2400). For example, when the incoming call signal that may cause annoying call does not include the incoming call number (when the telephone number is not notified), or the incoming call number that does not select automatic call reception was included In the case (in the case other than relatives or welfare personnel), the automatic reception process for the elderly is temporarily terminated. As a result, the subsequent automatic incoming call processing is not performed, and the incoming call is executed without executing the incoming call (on-hook) by operating the call button 31 (see FIG. 1), which is a normal reception procedure. Disappear.

  On the other hand, if the incoming call number has been registered (S2400), first, in order to notify the user of the telephone device 1 that there is a request for an incoming call for automatic incoming call, Then, a ringing tone different from that of a normal incoming call is output from the speaker 9 (S2500), and then, as a result of the notification, a reply sound due to the user of the telephone device 1 performing an automatic incoming call procedure is output from the microphone 11 (S2600), the feature of the reply sound captured from the microphone 11 is extracted (feature extraction) (S2700). The feature extraction here is substantially the same as the feature extraction process of S500 described above, so that the data for each frequency band acquired in the feature extraction of S500 and written in the automatic incoming call target feature storage area 59 is extracted. The purpose is to acquire information in a form that is easy to compare with features.

  After feature extraction (S2700), it is determined whether or not there is a touch by referring to the touched flag set in the process of S2200 (S2800), and the presence or absence of touch is determined as follows according to the determination result. The level of accuracy of determination of confirmation of intention to execute incoming call of the telephone device 1 is selected.

  First, when there is a touch, that is, when the housing 3 is held by the hand 37, it is determined that there is a low possibility that an erroneous incoming call will be executed even if the determination accuracy of the confirmation of the incoming call is lowered. Then, a process for searching for the start of a registered feature corresponding to the next extracted feature is performed (S2900).

  In the process of searching for the start of registered features corresponding to the extracted features (S2900), as shown in FIG. 8, first, the frequency distribution for 0.5 seconds is obtained from the data for each frequency band acquired by the feature extraction of S2700. Data is input (S2910), and then 0.5 seconds are read from the time-series data of the frequency distribution of features stored in the automatic incoming call target feature storage area 59 (0. 0 of the stored frequency distribution). 5 seconds) (S2920), the correlation between the frequency distribution data input in S2910 and the frequency distribution data read in S2920, here, as shown below, in the individual frequency bands of both data, The coincidence ratio is calculated when “1” indicating that a signal is detected is set (S2930), and the calculated degree of correlation is 50% or more. (S2940), and if the result of the determination is that the correlation is 50% or more, the corresponding flag is set in the corresponding flag storage area 65 (see FIG. 2) of the application memory 57 (see FIG. 2). S2950), the process of searching for the start of the registered feature corresponding to the extracted feature is temporarily ended. On the other hand, if the determination result in S2940 does not match the correlation degree by 50% or more, the corresponding flag is stored next. The area 65 is cleared (S2960), and the process of searching for the start of the registered feature corresponding to the extracted feature is temporarily ended.

A supplementary explanation of the coincidence ratio will be given below, although “1” indicating that a signal is detected in each frequency band of both data in the calculation of the correlation is set.
For example, assuming that the frequency distribution data as shown in the instruction 53 in the explanatory diagram of the output for each frequency band in FIG. 3 is input in S2700, the frequency distribution as shown in the instruction 53 is stored in the automatic incoming call target feature storage area 59. Is stored, the degree of correlation is calculated to be 100%. The calculation of the degree of correlation is sequentially executed for all data stored in the automatic incoming call target feature storage area 59.

  Also, assuming that frequency distribution data as indicated by instruction 67 is input in S2700, and if frequency distribution data as indicated by instruction 53 is stored in automatic incoming call target feature storage area 59, the correlation The degree is calculated to be 50 percent. That is, since the quantity that is “1” in the instruction 53 is “10” and the number of frequency bands that match in the instruction 53 and the instruction 67 is “5”, it is determined that there is a correlation of 50%. .

  By this process, the time series of the features extracted in S2700, that is, the frequency distribution time series, and the time series of the frequency distribution of the features stored in the automatic incoming call target feature storage area 59 are compared, and the number of matching frequency bands between the two is compared. Is equal to or greater than a reference value (appropriate value obtained by experiment, 50% in this case) is sequentially executed for all features stored in the automatic incoming call target feature storage area 59. When it is determined that the number of coincidence frequency bands is equal to or greater than the reference value, a determination result that there is a match is output.

  On the other hand, when there is no touch, that is, when the housing 3 is not held by the hand 37, it is highly likely that the user of the telephone device 1 does not know that there has been a request for an incoming call, and determination of intention confirmation is made. It is determined that it is necessary to increase the accuracy and prevent the erroneous incoming call from being executed, and a process of searching for 2 seconds from the start of the registered feature corresponding to the next extracted feature is performed (S3000). .

  In the process of searching for 2 seconds from the start of the registered feature corresponding to the extracted feature (S3000), as shown in FIG. 9, first, the frequency distribution of 2 seconds from the data for each frequency band acquired by the feature extraction of S2700. Is input (S3010), and then 2 seconds are read from the time series data of the frequency distribution of the feature stored in the automatic incoming call target feature storage area 59 (the stored frequency distribution of the frequency distribution). (Reads for 2 seconds) (S3020), calculates the coincidence ratio of the correlation between the time series data of the frequency distribution input in S3010 and the time series data of the frequency distribution read in S3020 (S3030), It is determined whether or not the calculated correlation degree matches 50% or more (S3040). Is set in the corresponding flag storage area 65 of the application memory 57 (S3050), and the process of searching for 2 seconds from the start of the registered feature corresponding to the extracted feature is temporarily terminated. If the correlation does not match 50% or more, then the corresponding flag storage area 65 is cleared (S3060), and a search is made for 2 seconds from the start of the registered feature corresponding to the extracted feature. The processing to be finished is once ended.

A supplementary explanation of the coincidence ratio will be given below, although “1” indicating that a signal is detected in each frequency band of both data in the calculation of the correlation is set.
For example, it is assumed that the frequency distribution data for 0.5 seconds as shown in the instruction 53 in the explanatory diagram of the output for each frequency band in FIG. When the frequency distribution for 0.5 seconds as shown in the instruction 53 is stored in the area 59 for 2 seconds in time series, the correlation degree for each 0.5 second is 100%, respectively, The minute time-series correlation is also calculated to be 100 percent. The calculation of the degree of correlation is sequentially executed for all data stored in the automatic incoming call target feature storage area 59.

  Further, assuming that the frequency distribution data as shown in the instruction 67 is input for 2 seconds in S2700, the data for 2 seconds of the frequency distribution as shown in the instruction 53 is stored in the automatic incoming call target feature storage area 59. If it is, the correlation degree for 0.5 seconds is 50%, and the time-series correlation degree for 2 seconds is also 50%.

  By this processing, the feature extracted in S2700, that is, the time series for two seconds of the frequency distribution is compared with the time series for two seconds of the frequency distribution of the features stored in the automatic incoming call target feature storage area 59, All the features stored in the automatic incoming call target feature storage area 59 are determined whether or not the number of coincident frequency bands between them is equal to or greater than a reference value (appropriate value obtained by experiment, 50% in this case). Are sequentially executed, and when it is determined that the number of coincident frequency bands between the two is equal to or greater than the reference value, a determination result indicating that there is a match is output.

  Therefore, compared with the case of S2900 in which the determination is made based on the correlation degree for 0.5 seconds, the correlation degree for 0.5 seconds has a predetermined correlation degree (50% or more) over four time series. It is necessary to have it. That is, it is possible to determine the degree of correlation of words of about 2 seconds such as “Yes Yes”.

  As a result, when the case 3 is not held by the hand 37, it is possible to make a determination based on the degree of correlation of the words for about 2 seconds, compared to the case where the case 37 is held by the hand 37 for making a determination by using the voice for about 0.5 seconds. The accuracy of the calculated value of correlation is improved.

  After the search of S2900 or S3000 described above, it is determined whether the incoming call signal is ongoing by determining whether the incoming call signal is ongoing (S3100). If the automatic reception process is once terminated and the call is continuing (S3100), it is determined whether or not there is a corresponding flag by checking whether or not a corresponding flag is set in the corresponding flag storage area 65 (S3200). If the presence flag is not set, it is not determined that there is a corresponding state, and the process repeats from the ringing tone output exclusively for the incoming call number (S2500) to the determination whether there is a corresponding state (S3200). If it is determined that there is a match, next, the wireless telephone unit 43 is caused to receive an incoming call to enter a call state (S3300), and the application memory 57 is touched. There is a touch carried out to clear the lag setting area 63 by performing the flag is cleared (S3400), once to end the automatic reception process for this old man.

  When an incoming call request is made by the above-described automatic reception process for the elderly, depending on whether or not the housing 3 is held by the hand 37, for example, when the hand 3 is held, the voice The intention of answering the incoming call is confirmed with a degree of correlation judgment accuracy (a sampling period corresponding to the start of answering), and the incoming call is executed, while holding the housing 3 with the hand 37. If not, it is possible to confirm the intention of the incoming call with a judgment accuracy (a sampling period corresponding to the length of the reply) and to execute the incoming call with a degree of judgment that can match the registered word as a reply. .

  Thereby, for example, when the telephone device 1 is put in a pocket or a bag and there is a request for an incoming call, it is possible to prevent the incoming call from being erroneously performed by surrounding sounds. In addition, when the telephone device 1 is held by the hand 37, confirmation of the intention of answering the telephone is completed with only a short utterance corresponding to the answering and part of the answering. The incoming call can be executed.

  When the telephone device 1 described above makes a ringing tone requesting an incoming telephone communication, it simply responds in the same way as previously registered, and it can send a specific destination registered in advance. Call communication that does not execute incoming calls simply by replying to incoming call requests from other than specified registered destinations. Incoming call execution procedure is obtained.

  From this, when a ringing tone that expresses a request for an incoming call is heard, it is possible to execute an incoming call only from a registered destination such as a family member by simply answering the same at any time and registered. Regarding a telephone call from a destination other than the call destination, an incoming call is not performed simply by answering, but a general ordinary telephone device 1 that performs an on-hook incoming call such as taking a handset or operating the call button 31 is used. Functions can be provided. As a result, the normal telephone device 1 functions as it is, and when a ringing tone for an incoming call is heard, only the sound such as a reply or applause that has been registered in advance is generated. It is possible to provide the telephone device 1 that can execute an incoming call only from a registered destination such as a welfare person, and an inadvertent telephone response such as inadvertent on-hook is not performed. It is possible to provide a technology that can be used, and for example, even if it is an elderly person whose judgment ability has deteriorated, it is possible to reliably enjoy the function of eliminating unwanted calls. Play.

  In addition, an environment is provided in which only a telephone call from a registered destination is reliably executed by simply replying to the ringing tone of a telephone communication request in the same manner every time, The attention required when answering a call can be made extremely low. Also, the procedure that can reduce this attention level is to reply in the same way every time, and it becomes possible to create a habit as a procedure that does not receive unwanted calls. Therefore, even an elderly person or a person whose judgment has deteriorated, it is only necessary to always reply in the same way, and an excellent effect is achieved that the function of eliminating unwanted calls is effectively utilized.

  The telephone device 1 has a telephone number as the registered content that affects the execution of the incoming call, so that the registration work is simple and clear. There is an extremely excellent effect that the registration work can be performed with less man-hours and without a doubt.

  The telephone device 1 outputs a dedicated ringing tone when there is a request for incoming telephone communication from a specific destination that has been registered in advance. It can be understood that it is a request for telephone communication from family and welfare personnel, and for example, it can also be understood that an incoming call is executed simply by replying `` Yes '', and it may be a nuisance call from a stranger Since it becomes possible to execute incoming calls without worry, there is an extremely excellent effect that the function of eliminating unwanted calls can be made more reliable.

  The telephone device 1 uses the matching state or the difference state of the voiceprints for the determination, so that the determination can be made with high accuracy to identify the individual or the sex, or whether the sound is a sound or a sound. This makes it possible to provide a high degree of freedom in design, such as making it possible to determine the degree of discrimination.

  When the telephone device 1 is not held by the hand 37 and is put in a pocket or the like, the telephone device 1 prevents the incoming call from being erroneously performed by the sound of the case 3 being worn by clothes or surrounding sounds, When the body 3 is held by the hand 37, the incoming call can be executed when the minimum sound that can confirm the intention to execute the incoming call, for example, the start of the voice such as “ha” is detected. For example, it is possible to determine a procedure for executing an incoming call reflecting an actual usage state of a mobile phone device or the like, and it is possible to provide a highly practical effect that high practicality can be provided.

  When the telephone device 1 holds the housing 3 with the hand 37, the degree of coincidence or difference between the pieces of acoustic information is determined based on the acoustic information obtained by a short sampling period. Therefore, it is possible to perform the incoming call when the minimum sound that can confirm the intention to execute the incoming call, for example, the start of the voice such as “ha” is detected, and the configuration provides high practicality. Has an excellent effect that it can be easily realized.
