Abstract

PURPOSE:To use one line for both a pushbutton telephone set and a rotary dial set by supervising the time of an input signal from the line so as to switch the connection of a pushbutton signal receiver and a voice recognition section based on the result of supervision. CONSTITUTION:When an incoming call detection section 1 detects an incoming call, a main control section 7 activates a relay RL, a contact rl is closed and the sending of a voice synthesis tone for confirmation is instructed to a voice synthesis control section 2 through a signal line B. The synthesized voice is such as ' Please input an identification signal'#'.' and the main control section 7 activates a time supervisory section 6 through a signal line C. When a pushbutton input'#' is inputted from a signal line E during the supervision, an output of an output terminal C' is activated to reset the time supervisory section 6 thereby continuing the PB mode. On the other hand, if the output at the output terminal C' of a comparator 9 is not active within a prescribed time, the time supervisory section 6 sets a PBE/F 10, a signal at an output terminal D is made active to switch a multiplexer 8 to the position of the voice recognition section 4 thereby forming the voice recognition mode.

Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a user identification circuit in an automatic voice response recognition device.

(Prior Art) Conventionally, in this type of device, there are two methods for connecting heels on the user side. One is for users with push/yu button telephones, and the other is for users with rotary dial telephones. The method for inputting data from these users to the automatic voice response recognition device is, in the former case, by inputting data using the Punyu button, and in the latter case, by inputting data by voice. In both cases, a telephone line is used, but the recognition method within the device is different for push-button input and rotary dial voice input, so the telephone line for push-button input and the rotary dial are different. Figure 3 is a block diagram showing an example of the configuration of a conventional connection method. In the first controller diagram, #l is a line for a push button, and this line includes an incoming call detection unit 3], a relay RLI for responding after detecting an incoming call, and a function to insulate the line side and the equipment. At the same time, a hybrid transformer T1 separates the output of the voice synthesized sound and the push button data input.
9. Speech synthesis control section 32 that outputs synthesized speech. Since the putunyu button input is a mixed frequency of two frequencies, a PB receiver 33 is connected to identify which key data it is. on the other hand,
#2 is a voice input line with a rotary dial, and like line #1, there are incoming call detectors 3, 1, relay RL2, ), hybrid transformer T2, voice synthesis control unit 35, and a voice input line that detects the words input by voice. A voice recognition unit 36 for recognition is connected. Lines #1 and #2 exchanged data with the main control unit 37 separately. Because of this connection configuration, the users of push button telephones and users of rotary dial telephones were fixed at the time of installation of the device.

(Problems to be Solved by the Invention) However, in the device with the above configuration, a line must be prepared for each user's telephone, and an incoming call detection section, a hybrid transformer, and a voice synthesis section are required in duplicate. Among other things, there was a connection error between the push button and rotary dial line on the equipment, and the downsizing.

This was disadvantageous from the viewpoint of reducing power consumption.

The present invention eliminates the disadvantage of the prior art of double investment in circuits as described above, allows one line to be used for both push buttons and rotary dials, eliminates connection errors during equipment installation, and saves energy. The purpose of this invention is to provide an excellent user identification circuit that can be made smaller and more compact.

(Means for Solving the Problems) The present invention provides a push-button signal receiver for identifying and receiving push-button input data from a user with a push-button telephone; In order to solve the problems of the prior art described above, the present invention aims at a user identification circuit in an automatic voice response recognition device equipped with a voice recognition unit that receives voice input data and performs voice recognition. A switching unit that switches the connection to the higher-level control unit of the push button signal receiver and the voice recognition unit, and a switching unit that time-monitors the input signal from the line and, based on the monitoring results, instructs the switching unit to switch the connection of the push-button signal receiver and the voice recognition unit to the higher-level control unit. This system is equipped with a time monitoring section that performs the following.

(Operation) In the present invention, the time monitoring section starts a time monitoring operation in response to an instruction from the higher-level control section, and monitors whether or not predetermined data is input from the line within a predetermined time.

This predetermined data may be, for example, key data sent when the user presses a specific button using a push-button telephone. Since the user of the rotary dial telephone does not send this key data, the other party can be identified by monitoring predetermined data, and the time monitoring section instructs the switching section to switch the connection. In accordance with this instruction, the switching section connects the designated circuit of the push button signal receiver and the voice recognition section to the upper control section. Therefore, it is not necessary to connect both the PB line and the rotary dial line, and the incoming call detection section, hybrid transformer, voice synthesis section, etc. can be shared, and line connection errors can be prevented.

(Example) Examples of the present invention will be described in detail below.

FIG. 1 is a block diagram showing the configuration of the user identification circuit of this embodiment. In the figure, 1 is an incoming call detection section, 2 is a speech synthesis control section, 3 is a PB receiver, 4 is a speech recognition section, 5 is a switching section, 6 is a time monitoring section, and 7 is a main control section. Switching section 5
is multiplexer 8, comparator 9 and P B F/F 1
Consists of 0. Again,.

L2 is an input terminal, rl is a line closing relay contact, and T is a hybrid transformer.

The input terminal L2 is connected to the incoming call detection section 1, the line closing contact R7, and the hybrid transformer T that insulates the line and the inside. The incoming call detection section 1 is connected to a higher-level main control section 7 by a signal line A. The secondary terminal of the hybrid transformer T is connected to the voice synthesis control unit 2 which converts the voice NO instructed by the instruction line B from the main control unit 7 into actual voice, and is further connected to the terminal port of the hybrid transformer T. is the D signal line Oζ, PB receiver 3
and is connected to the voice recognition section 1. The output E of the PB receiver 3 and the output F of the speech recognition unit 4 are respectively connected to input terminals 49 of a multiplexer 8, and the output of the multiplexer 8 enters an input terminal I of a comparator 90. Another input terminal of comparator 9 is a fixed data input to be compared with the data input to input terminal A. When the input data of the two input terminals 41 of the comparator 9 match, an output signal is output from the output terminal C to the reset input terminal C of the time monitoring section 6 and the P B F/F 10.
is connected to the reset input terminal of the circuit, and resets each circuit.

The time monitoring section 6 receives a time monitoring instruction from the main control section 7 through a signal line C at an input terminal A, and starts time monitoring. When the time is up, the output from the output terminal of the time monitoring unit 6 turns on υ, disabling the input from the input terminal 2 of the comparator 9, and simultaneously disabling the input from the input terminal C of the P B F/F 10. Set F/F 10. PBF/
In the initial state, FIO is in a reset state, and output terminal 2 is off, and at this time, multiplexer 8 is switched to the A side, that is, P
B receiver 3 is selected.

However, when the ON signal is input to the input terminal C of the PBF/F 10, the output terminal 2 is turned ON 9, and at this time, the multiplexer 8 selects the mouth side, that is, the voice recognition section 4. In this way, it becomes possible to automatically switch from the PB receiver 3 to the speech recognition section 4.

Next, the operation will be explained according to the time chart shown in FIG.

When an incoming call is detected by the incoming call detection section 1, the main control section 7 is notified of this by a signal iA. Then the main control section 7
turns on relay RL via the signal line for response and turns rl on.
Close. Thereafter, in order to determine whether the other party is using a push button or a rotary dial, a signal line 2 instructs the speech synthesis control section 2 to send out a confirmation speech synthesis sound. This synthesized sound is, for example, "Please input the recognition signal "#"". At the same time, the main control section 7
The time monitoring unit 6 is activated by This function becomes a time amplifier and stops after L time has elapsed. During this monitoring, when the button ``#'' is inputted via the signal line E (case ◯ in Fig. 2), the output of the output terminal C of the comparator 9 is turned on, and the time monitoring unit 6 is reset. Continue the PB mode (connected state with the PB receiver 4). On the other hand, if the output of the output terminal C of the comparator 9 does not turn on within the time (case 3 in FIG. 2), the time monitoring unit 6 outputs P B
When the F/F 10 is set and the output terminal 2 of the PBF/F 10 is turned on, the multiplexer 8 is switched to the voice recognition section 4 side, and the voice recognition mode is set.

(Effects of the Invention) As explained above in detail, according to the present invention, there is no need to connect both a PB line and a rotary dial line.
This has the advantage of eliminating the need for double investment in circuits and preventing erroneous connections. Furthermore, since the present invention is applicable to telephone lines, it is also applicable to other terminals.
