Abstract

PURPOSE: A method for automatically dialing an informed phone number through speaker subordinate isolated word voice recognition is provided to automatically dial a telephone number informed from a telephone number information service system through speaker subordinate isolated voice recognition. CONSTITUTION: If a user holds the receiver to receive 114 telephone information, the hook switch of the telephone gets off(201). If the user is connected with an information girl after pushing 114, he asks for the phone number of a desired subscriber or place(202). The information girl searches a telephone number database for the number and sends a relevant shaped machine sound. The user terminal receives it(203). At the same time, the terminal operates the start switch of a control circuit part to start recording(204). Simultaneously with the recording of the machine sound a voice recognition DSP is operated(205). The DSP judges whether the machine sound is an isolated sound information message(206). In case that it is the isolated sound information message, the DSP recognizes basic digits and matches the phone number with them(207). The matching-converted telephone number is displayed on a display part(209). The displayed number is sent to a telephone line through a call circuit part and a matching circuit part by the operation of the control circuit part(210).

Description

Auto-dialing method for speaker-dependant and word-isolated recognition 114 telephone number directory}

In the present invention, the telephone number guide (ie, 114 guide) service system in the general phone number that can be automatically dialed through the speaker-dependent isolated word voice recognition of the telephone number guided from the telephone number 114 guide A method and a computer readable recording medium having recorded thereon a program for realizing the method.

Currently, the general telephone number service provided by the public service, the user dials 114 to make a phone number call, and then the caller connects with the receptionist. Is retrieved from the 114 number database and the number is informed to the user. At this time, the user memorizes the guided phone number or memorizes in the head and ends the 114 call and then dials the corresponding number again. At this time, if there is no tool to memorize the guided phone number and the phone number is long and remembers incorrectly, it is inconvenient to dial the wrong phone number or to receive 114 instructions again.

To solve this inconvenience, 114 guides can directly connect the caller so that the caller can save the guide number and attempt to call the number. However, in order to provide a direct connection service to the user in the call processing device, the network configuration of the call processing device must be configured not only at the incoming line but also at the outgoing line, so the cost of installing and building the device increases in proportion to the demand for the direct connection. In some cases, a direct connection line with a user may be connected to a telephone number to receive a direct connection, in which case a detour path may be established, so a line cost may be increased.

In general, the basic classification of speech recognition includes speaker-independent methods for speech recognition for unspecified majority and speaker-dependent methods for speech recognition for specific persons. The dual speaker dependent method is relatively simpler to implement than the speaker independent method. In addition, there is a connection word recognition, which is a method of recognizing words connected in a classification by a recognition unit of speech recognition, and an isolated word speech recognition method that recognizes each individual word, and the recognition rate of the isolated word is much higher than the speech recognition rate of the connection sound.

Accordingly, in consideration of this point, the existing 114 telephone number guide method recognizes the telephone number guided by the number guide, and the 114 telephone number user can send out the corresponding number without any memo or memorization. In order to provide the convenience of dialing the guided phone number, 114 voices can be automatically dialed through the speaker-dependent and isolated word voice recognition method. Present process

The present invention devised to meet the requirements as described above, in the telephone number guide (ie, 114 guide) service system, the general user to the phone number 114 guided by the telephone number 114 guide speaker-dependent isolated word speech recognition An object of the present invention is to provide a method of automatically dialing a guide phone number for automatically dialing through a computer, and a computer-readable recording medium recording a program for realizing the method.

First, a part of the number memory device of FIG. 1 is a digital signal group obtained by extracting a signal pattern by voice recognition of the 114 guide machine sound corresponding to the numbers 0 to 9 and the recognition of the 114 guide machine sound. ) Is written using a ROM Writer, etc. to implement the basic database.

2 is a flowchart illustrating an embodiment of a method for automatically dialing a guide phone number according to the present invention.

As shown in FIG. 2, in the method for automatically dialing a guide phone number according to the present invention, a hook switch of a telephone is first turned off (201) when a user picks up the handset to receive 114 telephone guide.

Thereafter, the user dials 114 to send the DTMF to receive the telephone number guide (202) and is connected with the 114 guide. In this step, the user speaks the name or trade name of the place where the user wants to be guided, and the guide finds the corresponding place in the telephone number database and sends out a formal machine sound corresponding to the guide number. At the same time, the user terminal receives this (203). In addition, the terminal starts the recording by operating the drive switch (Start S / W) of the control circuit 17 (204). At the same time as the recording starts, the voice recognition DSP 15 is activated (205).

The machine sound guided by the 114 telephone number guide system 20 is usually guided in two ways, with the first announcement being guided in a continuous tone behavior (for example, 571-5700; The second announcement is guided as an isolated sound (for example, 571-5700, five to seven balls on seven days). In this case, the voice recognition DSP 15 determines whether it is an isolated sound announcement (206), and if it is an isolated sound, extracts the pattern of the isolated sound, stores it in the number storage device, and compares it with a database pattern corresponding to an already stored basic number. Recognize the base number to match the corresponding number (207). If not, the voice recognition process starts again (205).

After repeating the DSP recognition process (205 to 207) to the number of digits guided, the voice recognition process is terminated due to the end point recognition by the 114 guiding message of "No. Thank you" in the announcement. In this case, when the user knows the end point recognition, the end switch END sw of the control circuit 17 may be used.

Next, the matched and converted telephone number is displayed on the screen display unit 18 (209).

Subsequently, the phone number displayed on the screen is transmitted to the telephone line through the call circuit unit 12 and the matching circuit unit 11 in DTMF tones by the action of the control circuit unit 17 (210). A call can be initiated (211). After that, if the call is hooked up after the end of the call (212), all processes are terminated.

The present invention described above is capable of various substitutions, modifications, and changes without departing from the spirit of the present invention for those skilled in the art to which the present invention pertains, and the above-described embodiments and accompanying It is not limited to the drawing.

According to the present invention as described above, the user can automatically dial a desired telephone number by using a speaker-dependent and isolated sound recognition DSP method with a high voice recognition rate without a large voice database.
