[Detailed description of the invention] [Industrial application field] The present invention relates to an answering machine.

[Prior Art] Conventionally, an answering machine has been switched between its normal telephone function and its function as an answering machine by pressing a button to set or reset the answering machine function. Also,
Anyone could easily play the recorded content using a button.

[Problem to be solved by the invention] In order to popularize the use of answering machines, the conventional answering machines mentioned above were operated using buttons so that anyone could use them easily. Today, people are complaining about phones with a large number of buttons. In other words, mechanically operated telephones with a large number of buttons are complicated to use, giving a strong impression that they are complicated to use, especially among elderly people, and they are not able to operate using anything other than buttons. There was a desire to develop a simple answering machine. Furthermore, among young women, there is a demand for personalized answering machines, and there is a strong desire to have a telephone of their own, and moreover, there is a desire for an answering machine that can only be operated by one's own operation.

As mentioned above, conventional answering machines have the disadvantage that switching between the normal function and the answering function is complicated, and that they can also be operated by someone other than the owner, regardless of the owner's will.

SUMMARY OF THE INVENTION An object of the present invention is to provide an answering machine that can easily switch between a normal telephone function and an answering machine function, and can prevent the function from being switched by anyone other than the owner. It is.

[Means for Solving the Problems] The answering machine of the present invention includes: a telephone line connection end connected to a public network; a line control unit that detects an incoming call from the public network to the telephone line connection end; A telephone communication circuit that includes a receiver and transmits and receives voice signals of a call to the other party via the line control unit; a voice recognition unit that analyzes the voice pattern of the input voice signal for frequency components, etc.; and a voice signal of the received party. a recording and playback section for recording and playing back the recorded audio signal; a registration button section having an operation button for registering registered terms for switching modes such as an away mode and a playback mode; and the voice recognition section; a memory section that stores information representing registered terms for mode switching analyzed from a user's voice signal; When a registered term for mode switching is input as an audio signal from a speaker or the like, the audio pattern of the audio signal is analyzed by the voice recognition unit, and information representing the registered term indicated by the audio signal is stored in the memory unit. When a term for mode switching is input from the operator as an audio signal from the transmitter or the like, the audio recognition unit analyzes the audio pattern of the audio signal and converts it into the registration stored in the memory unit. It compares whether or not it matches the information representing the registered term, switches the function to a mode such as an away mode or playback mode indicated by the information representing the matched registered term, and when in the away mode, the line control unit When an incoming call is detected, the main control performs processing such as causing the recording/playback section to record the voice signal of the called party, and when in playback mode, plays back the voice signal of the called party recorded in the recording/playback section. It has a department.

[When the operator inputs a term for mode switching in the form of a voice signal, the voice pattern of the voice signal is analyzed by the voice recognition unit, and is registered in advance as a voice signal input by the user in the memory unit. If the information matches the registered term for mode switching, the function will be switched to the mode indicated by the matching information. The function can be switched to modes such as absentee mode and playback mode by operation, and the voice recognition unit has a specific speaker recognition function to distinguish the voice pattern of the voice signal input by the user from the voice pattern of another person. If the personal voice information of the operator is stored in the memory section and the mode is switched only when the analysis result of the operator's voice signal matches the personal voice information, the private voice information that only the owner can operate. It can be used as an answering machine.

[Example] Next, an example of the present invention will be described with reference to the drawings.

FIG. 1 is a block diagram of an embodiment of an answering machine according to the present invention.

This answering machine is equipped with a telephone line connection terminal 1, a line control section 2, a communication circuit 3, a voice recognition section 4, a recording/playback section 5, a micro, a registration button section 7, a memory section 8, and a main control section 9.

A telephone line connection end 1 is connected to a public network. Line control section 2
0 detects an incoming call from the public network to telephone line connection end 1
The telephone call circuit 3 includes a handset and receiver, and transmits and receives audio signals for a telephone call to and from the other party via the line control section 2. The voice recognition unit 4 analyzes the voice pattern of the input voice signal regarding frequency components and the like, and is capable of recognizing a specific speaker. Recording and playback section 5
includes a voice recording IC, records the voice signal of the incoming caller, and plays back the recorded voice signal of the incoming call for the user to hear. The registration button section 7 allows the user to press the call circuit 3.
It has an operation button for registering registered terms for mode switching using the transmitter (not shown) of the handset or the microphone inside the handset.

The memory unit 8 analyzes the voice pattern of the user's voice signal inputted from the transmitter or micro of the telephone call circuit 3 using the voice recognition unit 4, and distinguishes between the user's own voice signal and the voice signal of another person. Registered terms that indicate personal voice information for the purpose of communication, and registered terms such as "Starch", "Russ", "Zaitaku", and "Saisei" that correspond to the message button, away button, home button, and playback button, which were designed as operation buttons on conventional models. Remember information. The main control unit 9 is composed of a one-chip microcomputer, and the user operates the operation button of the registration button unit 7 to input registered terms such as “starch”, “rus”, “zaitaku”, and “saisei” using the transmitter or micro of the communication circuit 3. When input, the voice recognition section 4 analyzes the voice signal to store the user's personal voice information and registered terminology information in the memory section 8, and allows the operator to use the transmitter or micro to record the terminology indicating the operation content. When input as a voice signal, the voice recognition section 4 analyzes the voice signal, checks whether the voice pattern analysis result matches the user's personal voice information stored in the memory section 8, and If it is, the term indicating the input operation content will be stored in the memory section 8.
Check whether the registered term information matches the registered term information stored in , and call the mode indicated by the registered term "starch", "Rusu", "Zaitaku", or "Saisei" indicated by the matched registered term information. Switch the function of the device.

At this time, if the switched mode is away mode,
When the line control unit 2 detects that a call has arrived at the telephone circuit connection end 1 from the public network during the absence mode, the main control unit 9 causes the recording and playback unit 4 to record the voice signal of the called party, and switches to the playback mode. At this time, processing corresponding to each mode is performed, such as reproducing the voice signal of the called party recorded in the recording/reproducing section 4.

With the answering machine of this embodiment, if the user registers a registered term such as "starch" by voice in advance, the mode can be switched simply by uttering the registered term. There is no need to arrange a large number of speakers, and since the voice recognition section 4 has the ability to recognize a specific speaker, it will not be operated by another person's voice. In this embodiment, the voice recognition unit has a specific speaker recognition function, but if it were to have an unspecified speaker recognition function, it would be a general answering machine suitable for the elderly, etc. If you register numerical information such as "Zero", "Ichi", "Ni", and "San" and control information such as "Harashin" and "Teisei", it can also be used for automatic voice dialing.

Currently, voice recognition technology has a speech recognition rate of 95 to 98% for discrete words and specific words such as "a", "i", and "tsu" of a specific speaker using a fixed telephone, which is sufficient for use. It is at a level that can withstand

[Effects of the Invention] As explained above, according to the present invention, when a term for mode switching is input by an operator as an audio signal, the audio pattern of the audio signal is analyzed by the audio recognition unit, and the audio pattern is stored in the memory unit in advance. By checking the information representing the registered term in memory and switching the mode when a match is made, you can switch modes such as away mode and playback mode with a simple voice operation, so there are many mode switching buttons. There is no need to install a voice recognition unit, and if the voice recognition unit has a specific speaker recognition function and the user's personal voice information is stored in the memory unit, the analysis result of the operator's voice signal and the personal voice information can be combined. This verification has the effect of realizing an answering machine with a private function that can be switched only by the owner.
