Description

[Detailed description of the invention]

0001

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a telephone hold control device, and more particularly to a hold control device using voice recognition.

0002

[Prior Art] The hold function of a telephone is a function that allows a call to be made from the telephone to another line or to each other while keeping the line in use on hold. This is an important function for business phones and residential phones such as home telephones, when an extension (line) is shared by multiple phones, or when a single phone line is shared by multiple phones. ing.

[0003] Conventionally, this hold function has been added to the phone case or handset in the form of a hold button, and when you want to put an active line on hold in order to call someone inside, you must always operate the hold button. Was. This also applies when you are talking on the phone while doing business and you ask the other party to wait for a while.

0004

[Problem to be Solved by the Invention] However, pressing the hold button while performing work is extremely troublesome. In particular, if the hold button is built into the handset rather than the phone case, the user must remove the handset from the transmitting/receiving position where it is normally held against the ear, check the position of the hold button, and then operate it.

SUMMARY OF THE INVENTION Therefore, an object of the present invention is to provide a telephone hold control device that can put a telephone on hold without operating a hold button.

[0006]

[Means for Solving the Problems] A telephone hold control device according to the present invention includes a voice recognition device that recognizes a predetermined held voice pattern inputted from a transmitter, and a voice recognition device that controls the telephone based on a held voice detection signal from the device. This configuration includes a control unit that puts the device on hold and returns to the talking state when a voice of a certain level or higher is detected from the transmitter while on hold.

[0007]

[Operation] When the speaker says something like "Please wait a moment" during a call, the voice recognition device recognizes the held voice pattern and outputs a held voice detection signal. As a result, the control unit puts the telephone on hold. If a voice of a certain level or higher is detected from the handset while on hold, the call state is returned to. Therefore, even if you are busy working, you can automatically set and release the hold state just by voice without operating the hold button.

[0008]

Embodiments Hereinafter, embodiments of the present invention will be described with reference to the drawings.

In FIG. 1, a telephone line L is connected to a network control device (
NCU) 1. The line control unit 1 is a device that controls the telephone switching network, and performs operations such as starting up the central office exchange, sending out selection signals (such as dial pulses) during transmission, detecting ringing signals during reception, and forming a DC circuit. 2 is a CP that constitutes a telephone hold control device together with the voice recognition device 3;
U is the main control unit, 4 is a transmitter (microphone),
5 is a receiver (speaker). Reference numeral 6 denotes an operation unit, which includes switches such as a dial operation button, a line switching button, and a display lamp, as well as a hold button and a hold lamp that displays a hold state.

The speech recognition device 3 detects a match between the speaker's voice pattern and the registered held voice pattern by comparing it with a registered held voice pattern whose frequency has been analyzed and features have been extracted in advance, and performs pattern matching between the two. When it is detected, a held voice detection signal is output. The hold voice patterns handled here are, for example, multiple types of words such as "Please wait a moment." In order to increase the speech recognition rate of these words, several standard patterns are registered in the dictionary of the speech recognition device 3. Further, in order to enable general use, the speech recognition device 3 is designed to be able to recognize unspecified speakers as a speaker condition and continuous utterance as a utterance condition.

FIG. 2 shows a flowchart of the above-mentioned suspension control device.

[0012] Information is received from the other party in the following manner. That is, a ringing signal arrives through the telephone line L due to a call from the other party's station, the hook switch is operated (ie, on-hook), a DC circuit is formed with the other party's station, and a call is in progress (step 2). Here, subscribers
For example, a user holds a handset in his hand and brings the mouthpiece and earpiece close to his mouth and ears while having a conversation.

[0013] Next, the control by the CPU starts a process of checking whether or not a held voice is detected from the transmitted voice through the transmitter 4 and the voice recognition device 3 (step ①).

[0014] When the speaker speaks the preset words such as "Please wait a moment," the speech recognition device 3 compares this speaker's speech pattern with the held speech pattern registered in the dictionary. Then, if there is a match, a held voice detection signal is output. As a result, the CPU immediately connects the connection line 4a.
, 5a to disconnect the transmitter 4 and handset 5 from the network control device 1, and put the telephone on hold (step 2). At this time, the CPU simultaneously displays a display lamp belonging to the hold button (
(hold lamp) is lit (step ■). Also, in order to cancel the impact sound when the speaker places the handset on the housing or tabletop, set a cancellation timer (
Step ■).

[0015] Subsequently, the CPU prohibits input from the transmitter 4 until a predetermined timer period has elapsed (step ■■),
When the time is up, cancel this handset input prohibition (
Step ■). Then, the process returns from step ■ to ■, and waits for the pending state to be released (step ■■■■■).

[0016] Now, when the speaker picks up the handset again and speaks words such as "moshimoshi" through the transmitter 4, the voice signal is directly input to the control unit 2 without going through the voice recognition device 3. Ru. The CPU of the control unit 2 determines that the on-hold state should be released when the audio at a certain level or higher is input. That is, when a voice of a certain level or higher is input, the judgment in step ① becomes Yes, and the CPU resets the cancel timer and turns off the hold lamp (
Step ■), and return to the talking state (Step ■). That is, the transmitter 4 and the receiver 5 are connected to the network control device 1 through lines 4a and 5a, and a telephone conversation is enabled. still,
In this embodiment, in addition to being able to release the hold by voice input at a certain level or higher, the hold can also be released by turning the hold button OFF.

[0017]

[Effects of the Invention] As explained above, according to the present invention,
If the speaker says something like "Please wait a moment" during a call, the phone will go into a hold state, and if a voice above a certain level is detected from the handset while on hold, it will return to the call state.
Even if you are busy at work, you can automatically set and release the hold status just by voice, without having to press the hold button.
