Description

  The present invention relates to a telephone.

  When a phone call arrives, that is, when a phone call is received, the recipient of the call will respond to a call from an acquaintance, not a call from an unknown person such as a mischievous phone or a sales phone As such, it may be desirable to select whether or not to respond by the sender of the phone. For this purpose, it is necessary to identify the caller before the receiver answers the call.

  Conventionally, in order to identify a caller of a telephone, a technique called number display or CTI is used to search data from a caller's outgoing telephone number included in an incoming call signal and display information on the corresponding person. . As a result, information such as whether the caller is a registered person, whether the caller does not notify the caller telephone number, or whether the caller is from a public telephone is obtained. The caller can be identified to some extent.

  Moreover, in patent document 1, a caller is recognized by a caller's voice and a response sound or a ringing tone such as a bell sound is output according to the recognition result. As a result, the caller can be identified.

  However, in recent years, when an individual has a plurality of telephones such as mobile phones and home phones, and there is an incoming call from a telephone whose telephone number is not registered, for example, a newly purchased mobile phone, the outgoing call is made. It is not possible to specify whether or not the caller is an acquaintance from the telephone number. In addition, even when there is an incoming call that does not notify the outgoing telephone number or an incoming call from a public telephone, the outgoing telephone number cannot be obtained, so that the caller cannot be specified. In general, the recipient of a call rarely responds to an incoming call from an unknown outgoing telephone number or an incoming call without notifying the outgoing telephone number, and does not make a call again even if the incoming call history remains. .

  When specifying a caller from a caller telephone number, it is necessary to register the caller telephone number in a database or the like for each caller, for example. In particular, when the caller has a plurality of telephone numbers, it is necessary to register all of them. Therefore, when an acquaintance changes a telephone number or acquires a new telephone number, a registration operation for registering the telephone number in a database or the like must be performed.

  In Patent Document 1, a caller is recognized from the voice of the caller, and a response sound or a ringing tone such as a bell sound is output according to the recognition result. Therefore, the caller cannot be identified quickly.

  An object of the present invention is to provide a telephone that can quickly identify a caller.

  Another object of the present invention is to provide a telephone that can omit the registration work of registering a telephone number.

  The present invention relates to a telephone connected to a telephone line, a receiving unit for receiving an incoming signal and a voice signal from the telephone line, a first calling operation for notifying reception of the incoming signal by the receiving unit, and the first calling Created for each speaker based on a call unit that performs a second call operation different from the operation, a permitted telephone number for allowing the reception unit to receive the voice signal, and personality characteristic data representing personality A storage unit for storing a speaker model, an acquisition unit for acquiring a calling telephone number from the incoming signal received by the receiving unit, and the calling telephone number acquired by the acquiring unit in the storage unit. First determination means for determining whether or not the permitted telephone number is stored, and the permitted telephone number for which the calling telephone number is stored in the storage unit by the first determination means If it is determined that there is a first execution unit that causes the calling unit to execute the first calling operation, and the calling telephone number is not the permitted telephone number stored in the storage unit by the first determination unit If it is determined that, before allowing the calling unit to execute the first calling operation and the second calling operation, permission means for permitting reception of the voice signal by the receiving unit, and by the permission means, the receiving unit When reception of the audio signal by the receiving unit is permitted, an extraction unit that extracts the personality feature data from the audio signal received by the receiving unit, the personality feature data extracted by the extraction unit, and the storage A second determination unit that compares the speaker model stored in a section and determines whether or not a sender of the voice signal is a speaker registered in the speaker model; A second execution unit that causes the calling unit to execute the first call operation when the determination unit determines that the caller of the voice signal is a speaker registered in the speaker model; And a third execution unit that causes the calling unit to execute the second call operation when it is determined by the determination unit that the caller of the voice signal is not a speaker registered in the speaker model.

  According to the present invention, the calling telephone number is acquired from the incoming signal received by the receiving unit, the calling telephone number is compared with the permitted telephone number stored in the storage unit, and when they do not match, Personality feature data is extracted from the audio signal received by the receiving unit, the personality feature data is compared with the speaker model stored in the storage unit (speaker recognition), and differs depending on the comparison result. A call operation (first call operation or second call operation) is executed. As a result, speaker recognition is performed only for a specific caller, that is, a caller for which a permitted telephone number is not registered. Since this is not done, the caller can be quickly identified.

  The best mode for carrying out the present invention will be described with reference to the drawings. As the telephone 1 of the present embodiment, a cordless telephone is applied.

  FIG. 1 is a plan view showing the telephone 1, and FIG. 2 is a block diagram showing the configuration of the telephone 1.

  As shown in FIGS. 1 and 2, the telephone 1 according to the present embodiment includes a base unit 2 that is a main body and a handset 3 that communicates wirelessly with the base unit 2. The base unit 2 is connected to a PSTN (Public Switched Telephone Network) 4 and a commercial power source 5 which are telephone lines. The master unit 2 and the slave unit 3 are provided independently of each other, and the slave unit 3 is detachably attached to the master unit 2.

  The base unit 2 includes a CPU (Central Processing Unit) 6 that controls each unit. The CPU 6 includes a ROM (Read Only Memory) 7 that stores fixed data such as a control program executed by the CPU 6, and a RAM (a storage unit) that stores (writes) variable data such as work data in an updatable manner. Random Access Memory) 8 is connected via a system bus 9.

  Further, the CPU 6 includes an NCU (Network Control Unit) 10 connected to the PSTN 4, an RF (Radio-Frequency) unit 11 that is a wireless unit that performs wireless communication with the handset 3, a keyboard 12, a ring tone, and the like. A speaker 13 that is a sound output unit that outputs a signal, a power supply circuit 14 that is connected to a commercial power supply, a display 15 that is a display unit, and a hook switch 16 that permits reception of a sound signal from the PSTN 4 include a system bus 9. Connected through. The NCU 10 functions as a receiving unit and a transmitting unit, and the speaker 13 functions as a calling unit.

  The keyboard 12 is a numeric key 12a from “0” to “9” for inputting numbers, and a registrant such as a user or a close relative of the user changes the operation mode of the telephone 1 to the registration mode 1 or the registration mode 2. It has an external structure in which registration mode setting buttons 12b and the like for setting are arranged.

  The base unit 2 of the telephone 1 is provided with two LEDs 17 and 18 as light emitting means, and a light emission control circuit 19 for controlling the light emission of these LEDs 17 and 18 is also connected to the CPU 6 via the system bus 9. ing. The LED 17 emits blue light, and the LED 18 emits red light.

  The RAM 8 stores a permitted telephone number, a speaker model, and the like for permitting reception of a voice signal from the PSTN 4 (to permit reception of a voice signal from the caller's telephone). The speaker model is configured by registering individuality characteristic data representing individuality for each speaker. As the personality characteristic data, a cepstrum coefficient having personality is used.

  On the other hand, the subunit | mobile_unit 3 is also provided with CPU20 which controls each part. A ROM 21 and a RAM 22 are connected to the CPU 20 via a system bus 23. Further, the CPU 20 includes an RF unit 24 that is a wireless unit that performs wireless communication with the parent device 2, a keyboard 25, a speaker 26, a microphone 27 that is a sound input unit, and a rechargeable power source 28. They are connected via a bus 23.

  Of the various arithmetic processes executed by the CPU 6 in accordance with the control program stored in the ROM 7 built in the base unit 2 of the telephone 1 with such a configuration, the characteristic processes of the present embodiment will be described below. In addition, when real-time property is regarded as important, it is necessary to speed up the processing. For this purpose, it is desirable to separately provide a logic circuit (not shown) and realize various functions by the operation of the logic circuit.

  First, registration mode processing when the operation mode of the telephone 1 is registration mode 1 or registration mode 2 will be described with reference to FIG. FIG. 3 is a flowchart showing the flow of registration mode processing. Registration mode 1 is an operation mode for registering a permitted telephone number, and registration mode 2 is an operation mode for registering personality characteristic data (speaker model generation) for each speaker.

  As shown in FIG. 3, it is determined whether or not the operation mode of the telephone 1 is the registration mode 1 (step S1), and it is determined whether or not the operation mode of the telephone 1 is the registration mode 2 (step S11). ), Waiting for selection of registration mode 1 or registration mode 2 (N in step S1, N in step S11). The operation mode is set to the registration mode 1 or the registration mode 2 when a user or a registrant such as a user's close relative operates the registration mode setting button 12b of the keyboard 12. That is, whether or not the operation mode is the registration mode 1 or the registration mode 2 is determined based on whether or not the registration mode setting button 12b is operated. When the registration mode setting button 12b is not operated, the operation mode of the telephone 1 is set to the interactive mode.

  When it is determined that the operation mode of the telephone 1 is the registration mode 1 (Y in Step S1), the telephone number input by the numeric key 12a of the keyboard 12 is acquired (Step S2), and the telephone number is permitted. The telephone number is stored in the RAM 8 which is a storage unit (step S3). Thereby, the registration process of the permitted telephone number is completed. If it is desired to perform the registration process of the permitted telephone numbers for a plurality of persons, the processes in steps S2 to S3 may be repeated.

  When it is determined that the operation mode of the telephone 1 is the registration mode 2 (Y in Step S11), an audio signal is acquired from the audio input from the microphone 27 of the handset 3 (Step S12), and the acquired audio signal is acquired. Personality feature data is extracted from (step S13). This personality characteristic data is stored in the RAM 8 which is a storage unit (step S14). This completes the speaker registration process (speaker model creation process). When such speaker registration processing is desired to be performed for a plurality of persons, the processing in steps S12 to S14 may be repeated.

  Next, the dialogue mode process when the operation mode of the telephone 1 is the dialogue mode will be described with reference to FIG. FIG. 4 is a flowchart showing the flow of interactive mode processing.

  As shown in FIG. 4, when the operation mode of the telephone 1 is the conversation mode, when the telephone 1 receives a call from the outside (incoming call from the caller's telephone), that is, an incoming signal from the PSTN 4 via the NCU 10 Is received from the incoming signal (step S21: acquisition means). It is determined whether or not the acquired calling telephone number matches the permitted telephone number recorded in the RAM 8 (step S22: first determination means).

  If it is determined that the acquired calling telephone number matches the permitted telephone number (Y in Step S22), the ringing sound A is set as the ringing sound (Step S30), and the calling operation for outputting the ringing sound A (first The calling operation) is executed by the speaker 13 (step S31: first execution means). As the ringing sound A, a normal bell sound or voice is used.

  When it is determined that the acquired calling telephone number does not match the permitted telephone number (N in Step S22), the hook switch 16 is off-hooked to permit the NCU 10 to receive a voice signal (Step S23: permission means), Plays back a response voice prompting the caller to speak, such as “Perform voice authentication. Speak your name”, that is, send a response voice signal to the PSTN 4 via the NCU 10 (step S24: transmission means) ).

  A voice signal is acquired from the voice uttered by the caller according to the response voice (step S25), and personality characteristic data is extracted from the acquired voice signal (step S26: extraction means). The personality feature data of the speaker model recorded in the RAM 8 is read, the read personality feature data is compared with the personality feature data extracted in step S26, and the utterance in which the sender is registered in the speaker model is compared. It is determined whether it is a person (step S27: 2nd determination means). The ringing tone output from the speaker 13 is changed to the ringing tone B or the ringing tone C different from the ringing tone A according to the determination result (speaker recognition result).

  That is, when it is determined that the caller is a speaker registered in the speaker model (Y in step S27), the ringing tone B is set as the ringing tone (step S28) and the ringing tone B is output. The operation (third calling operation) is executed by the speaker 13 (step S31: second execution means). If it is determined that the caller is not a speaker registered in the speaker model (N in Step S27), the ringing tone C is set as the ringing tone (Step S29), and the ringing operation for outputting the ringing tone C (the first operation) (2 calling operation) is executed by the speaker 13 (step S31: third execution means).

  For example, when the personality feature data of the speaker model matches the personality feature data extracted in step S26, that is, when the caller is a speaker (registered speaker) registered in the speaker model. The ringing tone B is output as a ringing tone of a voice “A call from Mr. XX” different from the ringing tone A, or a ringing tone having a volume higher than that of the ringing tone A. Note that the ringing tone B only needs to be different from the ringing tone C, and may be the same ringing tone as the ringing tone A. In this case, in step 31, the speaker 13 is caused to execute the first call operation.

  On the other hand, if the personality feature data of the speaker model does not match the personality feature data extracted in step S26, that is, if the caller is not a speaker registered in the speaker model, As the sound C, a ringing sound of a voice “a phone from the person who failed to recognize” different from the ringing sound A and the ringing sound B is output, or the ringing sound is not output. Note that when outputting a voice as a ringing tone, the voice data is stored in advance in the ROM 7 or RAM 8 or the like.

  As described above, according to the present embodiment, the outgoing telephone number is acquired from the incoming signal received by the NCU 10 (step S21), and the outgoing telephone number is compared with the permitted telephone number stored in the RAM 8 (step S22). If they do not match (N in step S22), personality feature data is extracted from the received voice signal (step S26), and the personality feature data and the speaker model stored in the RAM 8 are extracted. Are compared with each other (step S27), and the ringing tone B or the ringing tone C is set according to the comparison result (speaker recognition result) (steps S28 and S29). A call operation or a second call operation) is executed (step S29). As a result, speaker recognition is performed only for a specific caller, that is, a caller for which a permitted telephone number is not registered. So that the caller can be quickly identified.

  In addition, even when an acquaintance (related person) who is a caller makes a call from the telephone 1 whose caller telephone number is not registered in advance or a public telephone or the like whose caller telephone number cannot be specified, the comparison result (speaker recognition result) ) To change the ringing tone. That is, since different call operations, for example, call operations with different ringing sounds, are executed depending on the registration status of the caller with respect to the telephone 1, the caller from the permitted telephone number is registered only in the speaker model. It is possible to notify whether the caller is an existing caller or an unknown caller. As a result, the receiver can specify the caller without calling the telephone.

  In the present embodiment, the permitted telephone number is stored in the RAM 8, but the present invention is not limited to this. For example, a rejected telephone number may be stored in order to reject reception of a voice signal from the PSTN 4. In this case, in step 22 shown in FIG. 4, it is determined whether or not the calling telephone number matches the rejected telephone number. If it is determined that the calling telephone number matches the rejected telephone number, the process proceeds to step S23. If it is determined that the calling telephone number does not match the rejected telephone number, the process proceeds to step S29. For example, “number starting with 090” is stored in the RAM 8 as the rejected telephone number.

  In this embodiment, the permitted telephone number and the speaker model are stored in the RAM 8, but the present invention is not limited to this. For example, the RAM 8 is provided corresponding to each of the permitted telephone number and the speaker model. You may make it store in.

  In the present embodiment, the ringing tone output from the speaker 13 is changed to the ringing tone B or the ringing tone C according to the comparison result (speaker recognition result) in step S27. Depending on the comparison result, the caller's calling telephone number may be stored in the RAM 8 as a permitted telephone number (recording means). That is, when the personality feature data of the speaker model matches the personality feature data extracted in step S26, that is, when the caller is a speaker (registered speaker) registered in the speaker model. Is stored in the RAM 8 as the permitted telephone number. As a result, for example, even when a caller who has been registered in the RAM 8 as the permitted telephone number only for the mobile phone number makes a call from the home telephone, the telephone number of the home telephone is automatically stored in the RAM 8 as the permitted telephone number. In other words, since the database relating to the permitted telephone number of the telephone 1 is automatically updated, the registration work for registering the permitted telephone number or the like by operating the numeric keys 12a of the keyboard 12 can be omitted.

  In the present embodiment, the speaker 13 is used as the calling unit. However, the present invention is not limited to this. For example, the LEDs 17 and 18 may be used as the calling unit. At this time, if the personality feature data of the speaker model matches the personality feature data extracted in step S26, that is, if the caller is a speaker registered in the speaker model, the blue color When the personality feature data of the speaker model does not match the personality feature data extracted in step S26, that is, the caller is registered in the speaker model. If the speaker is not a speaker, the red LED 18 is caused to emit light (second call operation). The blue LED 17 functions as a calling lamp.

  In this embodiment, a cordless telephone is applied as the telephone 1. However, the present invention is not limited to this. For example, a cellular phone, a telephone having a facsimile function, a personal computer having a telephone function, or the like may be used.

  In the present embodiment, when the second determination means determines that the caller of the audio signal is a speaker registered in the speaker model, the caller's calling phone number is used as the permitted phone number. Since the storage means for storing in the RAM 8 which is a storage unit is provided, it becomes possible to store the caller's outgoing telephone number registered in the speaker model in the RAM 8 as a permitted telephone number. Registration work for registering a permitted telephone number by an operation on 12a can be omitted.

  In the present embodiment, when it is determined by the second determination means that the caller of the audio signal is not a speaker registered in the speaker model, the calling phone number of the caller is stored as a rejected phone number. Since it is possible to store the calling telephone number of the caller who is not registered in the speaker model in the RAM 8 as the rejected telephone number, it is rejected by an operation on the numeric key 12a of the keyboard 12. Registration work for registering telephone numbers can be omitted.

  In this embodiment, when reception of a voice signal is permitted by the NCU 10 that is a transmission unit that transmits a signal to the PSTN 4 that is a telephone line, and the NCU 10 that is a reception unit by the permission unit, the NCU 10 Since the transmission means for transmitting the prompt response voice signal is provided, it is possible to prompt the caller to utter, so that the voice of the caller can be reliably acquired.

  In the present embodiment, the speaker 13 serving as a calling unit performs a third calling operation different from the first calling operation and the second calling operation in addition to the first calling operation and the second calling operation, and the second executing means. Causes the speaker 13 to execute the third call operation instead of the second call operation, so that different call operations, for example, call operations with different ringing sounds, are executed depending on the registration status of the caller with the telephone 1. In addition to notifying whether or not the user is an acquaintance, it is possible to notify whether or not the speaker is a registered caller.

  In the present embodiment, since the speaker 13 serving as a calling unit is a voice output unit that outputs voice, the name of the caller can be notified by voice, so that the receiver can easily call the caller. Can be specified.
