Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to an answering machine, and more particularly to an answering machine that can be remotely controlled by voice.

[Prior Art] A conventional answering machine detects a call from a caller, sends a response message prerecorded on a tape, etc. to the telephone line, and then sends a request message from the caller on a tape, etc. The disadvantage of this method is that the requirements can only be confirmed by recording the recorded message and later manually rewinding the tape and playing back the message, and the requirements cannot be known until the answering machine is returned to the place where the answering machine is installed. there were.

In addition, in view of the above-mentioned problems, when a certain period of time has elapsed, another telephone calls the answering machine, or when the answering machine receives a call from another person, it automatically outputs a predetermined telephone number signal. This will cause the pager of the person who is out to ring, the person carrying the pager will call the answering machine from a nearby telephone, and when there is a response from the answering machine, a generator will be installed that will generate a special signal tone. A tape that is pressed against the mouthpiece of a telephone and sends a special signal tone to the answering machine to read the recorded content, and the answering machine that receives and receives the special signal responds to the tape, which is used to record requirements, for example. To rewind the tape and receive other special signal tones, use methods such as playing the rewound tape and transmitting it to the telephone line.

The recorded content was read out by remotely controlling the answering machine via another telephone.

However, this method requires the user to carry a generator that generates a special signal sound at all times, which is very inconvenient. Further, the generating device requires a power source, and it is necessary to secure the power source. For example, if the power source is a battery, if the battery runs out, the answering machine cannot be remotely controlled.

[Object of the Invention] The present invention has been made in order to eliminate the drawbacks of the above-mentioned conventional technology. To provide an answering machine that can be easily operated even in difficult situations.

[Summary of the Invention] The object of the above is to provide a speech recognition unit that recognizes specific audio information from audio information sent via a telephone line, and to record according to the specific audio recognized by the audio recognition unit. This is accomplished by an answering machine that plays messages such as requirements from other callers and sends them to the telephone line.

[Example] Hereinafter, one embodiment of the present invention will be described with reference to the drawings.

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

In the figure, numeral 1 is a called detection circuit, which detects calls from the office lines Ll and L2. Reference numeral 2 denotes a response tape deck, which generates a tape audio signal output on which predetermined messages and signal tones are recorded. 3 records the caller's message using a recording tape deck.

A control circuit 4 controls various operations of the apparatus based on the called signal from the called detection circuit 1 and the recognition signal from the voice recognition circuit 5. 5 is a voice recognition circuit, which is connected to the central office line L.
The same voice information as the voice information stored in the voice information storage section 6 is recognized from the voice from the caller from L2 and the response message from the response tape deck 2. Reference numeral 6 denotes a voice information storage unit that stores voice information to be recognized by the voice recognition circuit 5, and 7 is a relay contact, which forms a DC loop for the office lines Ll and L2 when the called detection circuit l detects a call. It is energized and closed.

9 is an automatic dialing device (hereinafter referred to as ACU), which outputs a predetermined telephone number signal.

Usually this phone number is for a pager.

Further, 10 is a line transformer.

(2) Operation of this embodiment The operation of this embodiment will be described below with reference to the operation flowchart of FIG.

Normally, the called detection circuit 1 always detects the office lines LL and L in step Sl.
It monitors whether or not there is a call from station line L1 or L2 using a known method, and notifies the control circuit 4 of the call. Upon receiving the call detection from the call detection circuit 1, the control circuit 4 closes the relay contact 7 in step S3 to form a DC loop in the office line. Next, in step S5, the response tape deck 2 is driven to output the prerecorded response message to the office lines Ll and L2 via the line transformer 10.

A beep sound indicating this is recorded at the end of the response message on the response tape deck 2, and when this beep sound is detected by the voice recognition circuit 5, a beep sound recognition signal 21 is sent to the control circuit 4.
is output. - The control circuit 4 detects the completion of transmission of the response message to the office lines L1 and L2 by the beep recognition signal 21, and proceeds from step S7 to step S9, where the business recording tape deck 3 is started in the recording state.

Here, an endless tape is set in the response tape deck 2, which automatically stops when the response tape reaches the starting end position after sending out the beep sound, and when it is started next time, it sends out the response message again from the beginning.

When the caller receives a beep from the answering tape deck 2, the caller sends out a message following the beep, so that the message is sequentially recorded on the message recording tape deck 3.

When the caller ends the call and disconnects the circuit, a two-two tone is sent through the line transformer 10, which is recognized by the voice recognition circuit 5 and outputs a call end signal 22. When the control circuit 4 receives this end-of-call signal 22, it proceeds from step 515 to step S1.
7, the relay contact 7 is opened and the station lines Ll and L2 are opened.

Next, the control circuit 4 checks in step 519 whether or not the recording tape deck 3 is currently recording. If it is recording, the control circuit 4 proceeds to step 541 to stop the recording tape deck 3 and close the relay contact 7 again. Touching again, the station line Ll,
A DC loop is formed in L2, and in the subsequent step S43, wait until a dial tone comes from the station line Ll and L2. When the dial tone comes, the ACU 9 is activated in step S45, and a preset dial tone or MF signal tone is output. do.

By setting the telephone number set in the ACU 9 as a telephone number for calling a pager, it is possible to promptly notify the user that a call has been made to the answering machine while the user is away.

A person who receives a call from this telephone answering machine using a pager calls the telephone answering machine from another telephone if necessary. Then, following the beep from the response tape deck 2, the message recording tape deck 3 can be remotely controlled by voice from the mouthpiece of the telegraph machine to listen to the recorded message.

First, following a beep sound, a voice command is sent to instruct the rewinding operation of the recording tape deck 3, such as ``Rewind'', ``Rewind''. Then, the voice recognition circuit 5 of the answering machine of this embodiment compares the voice pattern recorded in the voice information storage section 6 with the voice information sent, and when it recognizes that there is a digit instruction for 'rewind', it starts winding. A return signal 23 is output to the control circuit 4.

When the control circuit 4 receives the rewind signal 23, the process proceeds to step S.
The program then proceeds to step 521, where recording on the business recording tape deck 3 is stopped and rewinding of the tape is started. Next, step S23. The process waits for the end of rewinding in S25.

Here, a voice instructing 11 in the current action, such as ``G'' and ``1'' in the middle, is sent from the mouthpiece, and when this is recognized, a ``11 in middle'' signal 24 is sent from the voice recognition circuit 5. Among these, upon detection of the 11 signal 24 or the end of rewinding, the process proceeds from step S23 or step S25 to restep S27,
The rewinding of the business recording tape deck 3 is stopped and the process returns to step Sll again.

In this way, when the business recording tape deck 3 is rewound by remote control using voice from another telephone,
Next, similarly, from the mouthpiece, an instruction is given to the recording tape deck 3 to reproduce the recorded content, such as ``playback φ playback''.

Then, the voice recognition circuit 5 recognizes this reproduction instruction and outputs a reproduction signal 25. When the control circuit 4 receives this reproduction signal 25, it proceeds from step S13 to step S31, stops the business recording tape deck 3, and then performs reproduction.

Then, in step S33, voice signals instructing playback mode 11, such as ``Medium 1 To'', ``Medium 1 To'', are output from the station lines Ll and L2, and a medium 1F signal 24 is output from the voice recognition circuit 5. After waiting, when the middle 11 signal 24 is output, the playback is stopped at step S35, and the process returns to step Sll.

In this way, the customer's message recorded on the answering machine using a pager or the like can be known simply by giving a voice instruction without requiring any special equipment or the like.

If you want to check the reproduced message again, you can instruct to rewind it again, and then instruct playback to read out the recorded message as many times as you like and check it from the earpiece of another telephone.

After confirmation, the receiver and handset of the telephone that made the call is placed and the central office line is opened.
7, the process proceeds to step S19, and as it is determined in step S19 whether or not the recording tape deck 3 is recording, it is determined that recording is not in progress, so the process returns to step S1, where the pager is called, and the pager is called again. wait for a call.

The voice information recognized by the voice recognition circuit 5 described above is stored in advance in the voice information storage section 6, but in order to store this voice information, the answering machine operator must use the microphone or handset of the telephone to voice the voice information. The voice instructions are registered and recognized based on the registered voice instruction information.

Further, as described above, when the same instruction is recognized twice or more, by inputting the instruction, there is almost no chance of erroneous recognition.

Furthermore, the voice recognition in the voice recognition circuit 5 is not limited to the above-mentioned example, and may be performed by sending a recitation code. This can be easily done by changing the registration in the voice information storage unit 6. I can do it.

In the explanation above, we have described an example in which the ACU9 automatically calls another telephone after the recording of the message on the recording tape deck is completed. Of course, the person may remotely control the recording tape deck at any time.

[Effects of the Invention] As explained above, according to the present invention, an answering machine can be simply called from another telephone without using any special equipment, and a voice signal can be output from the mouthpiece of the called telephone. It is possible to easily read messages from customers etc. recorded on an answering machine by simply giving an instruction.

Further, when a call is received from a customer or the like, the telephone number of a pager or the like is automatically called, so that the fact that there is a call can be immediately notified.
