Description

DETAILED DESCRIPTION OF THE INVENTION Technical Field of the Invention The present invention relates to a speaker verification vending machine that performs personal verification based on voice and password input to sell products.

<Background of the Invention> Conventional speaker verification vending machines determine whether or not there is a registered voice that matches the input voice when a user purchases an item. This method determines whether or not a product can be sold.

Therefore, in the case of this type of vending machine, the input voice must be compared point by point with all the voices registered in advance in the voice registration device, so the comparison process takes a long time and the matching accuracy is low. There is a disadvantage.

<Purpose of the Invention> The present invention is a novel speaker verification method that speeds up verification processing and improves verification accuracy by extracting registered speech to be verified based on a password input by the user. The purpose is to provide type vending machines.

<Configuration and Effects of the Invention> In order to achieve the above object, the present invention provides a means for inputting a voice and a PIN number in the customer service department, and when a user inputs a PIN number, the speaker verification unit checks this number. We decided to extract the registered voice that matches the , and compare the characteristics of this registered voice with the input voice to determine whether the user is the user himself or herself.

According to the present invention, only one registered voice is extracted based on the password input by the user and compared one-to-one with the input voice, so detailed voice comparisons can be performed.
The reliability of personal verification is improved and the verification processing time is significantly shortened. Furthermore, since a double check of the password and the voice verification is performed, the verification accuracy is further improved, which is an excellent effect of achieving the purpose of the invention.

<Description of Embodiments> The drawing shows an example in which the present invention is implemented in a voice verification type automatic ticket vending machine. , a display 12 that displays the user's operating procedure step by step, and a number selection key 13 for inputting a password are provided. In addition, an input capotan switch 14 for instructing input of data such as a password, and a correction button switch 15 for correcting input data are arranged on the double side of the button switch 11, A voice input device 16 is provided for inputting the user's voice.

Further, below the number selection key 13, there are provided an account selection button switch 17 for the user to select the ticket to purchase, and a receiving port 18 for taking out the sold ticket.

FIG. 2 shows an example of a circuit configuration of a voice verification type vending machine according to the present invention.

In the figure, CPU (Centr+II Processin
g Unit ), ROM (Read Only Me
The control device 21, which includes a ROM, etc., decodes and executes the program in the ROM, writes and reads data to and from the password memory 24, the input voice memory 26, and the registered voice memory 28, and performs various functions related to speaker verification and product sales. In addition to executing the process, the switch input circuit 2
2. Controls each input/output operation of the audio input circuit 25, display control circuit 23, transmission control section 27, and speaker verification section 29.

The switch input circuit 22 sends each switch signal of the start button switch 11, the input capotan switch 14, the correction button switch 15, the account selection button switch 17, and the key switch signal of the number selection key 13 to the control device 21, and performs voice input. The circuit 25 similarly sends the user's voice input from the voice input device 16 to the control device 21. Further, the display control circuit 23 controls the display operation of guide characters for the user, and the transmission control unit 27 transmits the input password to the host computer 4 connected online, and also transmits the registered voice data from the host computer 4. receive.

The password memory 24 stores the password input by the user using the number selection key 13, and the input voice memory 26 stores the password input by the user using the number selection key 13.
The voice input by the user through the voice input device 16 is stored. The voice registration memory 28 also stores registered voices sent from the voice registration device 3 through the host computer 4. Furthermore, the speaker verification unit 29 uses the input voice memory 26
The characteristics of the input voice and the voice registered in the voice registration memory 28 are compared and verified.

The voice registration device 3 is directly connected online to the host computer 4, and includes a transmission control circuit 31 that receives a password and transmits the registered voice, and a voice registration memory 33 that stores the registered voice and the password as a pair. , searches for a password that matches the received password, retrieves the corresponding registered voice from the voice registration memory 33, and sends it to the transmission control circuit 3.
1, and a CPU 32 that sends data to the CPU 1.

FIG. 3 shows an example of a password, and the password consists of an individual number dedicated to the user and a voice registration machine identification number that identifies the voice registration machine in which the password is stored.

FIG. 4 shows the operation control flow of the speaker verification type automatic ticket vending machine.

First, when the user presses the start button switch 11, step 51 becomes "YES", the ticket vending machine 1 shifts from the ticket vending standby state to the ticket vending start state, and the display 12 shows [
Please enter your PIN number. ” etc. will be displayed. When the user presses the number selection key 13 to input a password, the input number is displayed on the display 12.

If the number is correct, the user presses the input button switch 14, thereby storing the password in the password memory 24 (step 52). Subsequently, the display 12 displays a message "Please enter a keyword." When the user speaks a predetermined keyword into the voice input device 16, it is determined whether the voice input keyword is correct or not, and if it is correct, the message "Keyword has been input" is displayed on the display device 12. In the next step 53, the input voice is stored in the input voice memory 26 via the voice input section 25.

Then, when the user presses the confirmation button switch 11, the CP
The U21 transmits the PIN number to the host computer 4 via the transmission control unit 27 (Step 54), and the host computer 4 searches the voice registration device 3 for registered voice data that corresponds to the same number as the PIN number. request that it be sent.

In this way, when the search for the password is completed in the voice registration device 3, the transmission control unit 27 receives the registered voice data from the voice registration device 3 through the host computer 4 in step 55, and this registered voice is stored in the registered voice memory 28. be done (
Step 56). Next, the speaker matching unit 29 compares and matches the characteristics of the input voice and the registered voice, and if the characteristics of both voices match, the determination in step 57 is °'YE.
S″″, and it is determined that the user is the registrant. Then, in the next step 58, the account selection button switch 1
When 7 is pressed, the determination becomes "=YES" and a ticket is issued (step 59).

Incidentally, if it is determined in step 57 that the registrant is not the registrant as a result of the voice verification, the message "Tickets cannot be sold" is displayed on the display 12 and the process ends.
