Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a voice response device, and more particularly to a voice response device having an output voice monitoring function and a voice monitoring method thereof.

[Conventional technology]

As shown in FIG. 3, the conventional voice response device includes a control section 30, a voice memory 31, and voice response sections 32-1 to 32.
-4 and D/A (digital/analog) converter 33
-1 to 33-4, and a switching section 35. However, FIG. 3 is an example in the case of four lines.

The control unit 30 instructs the voice response units 32-1 to 32-4 to output voice. The voice memory unit 31 stores necessary voices in advance in a digitized manner, and the voice response unit 3
2-1 to 32-4 read data corresponding to the voice instructed by the control unit 30 from the voice memory unit 2, and
It is sent to A converters 33-1 to 33-4. The D/A conversion units 33-1 to 33-4 are voice response units 32-1 to 32-4.
The digital signals sent from the converter convert the digital signals into analog audio signals 510-813 and output them as output audio.

On the other hand, the analog signal MIO is a monitor signal,
Any one of the four lines, that is, output audio 3
Any one of 10-313 is output. The switching section 35 is
By selecting monitor audio MIO, SIO~S1
The audio of any one line of 3 is output as monitor audio MIO.

[Problem to be solved by the invention]

With conventional voice response devices, all output audio is input to the switching unit and the audio of the desired line is selected and used as monitor audio, so if the number of audio output lines is large, the number of signals input to the switching unit will also increase. However, there are disadvantages in that the circuit scale of the switching section increases and it becomes difficult to secure signal lines.

An object of the present invention is to eliminate the above-mentioned drawbacks and provide a voice response device and a voice monitoring method thereof that do not require a complicated switching unit even when the number of voice output lines is large.

[Means to solve the problem]

The present invention multiplexes audio digital signals divided and read out from an audio memory unit in a time division manner according to instructions from a control unit, and when a line for audio monitoring is specified, the audio digital signals corresponding to the line are multiplexed. is converted into an analog signal and output as a monitor audio signal.

The present invention also provides a voice response device including a plurality of voice response units that read voice data from a voice memory unit according to instructions from a control unit, which includes an audio bus that multiplexes audio digital signals output from the voice response units in a time division manner; , a line setting unit that sets a line for audio monitoring; and a digital-to-analog conversion unit that converts the audio digital signal of the corresponding line on the audio bus into an analog signal and outputs it as a monitor audio signal according to the setting of the line. It is characterized by having the following.

Furthermore, the present invention provides a voice response device including N voice response units (N is an integer) that reads voice data from a voice memory unit according to instructions from a control unit, in which the voice data of the N voice response units is read out from the voice memory unit. an audio bus that is sequentially assigned to time slots and multiplexed in a time-division manner; a line setting unit that sets a line for audio monitoring; It is characterized by comprising a digital-to-analog conversion section that converts the signal into a signal and outputs it as monitor audio.

[Example] Next, an example of the present invention will be described with reference to the drawings.

FIG. 1 is a block diagram of a circuit showing an apparatus according to an embodiment of the present invention, and FIG. 2 is a diagram showing an example of the configuration of an audio bus. It should be noted that the number of audio output lines and the number of voice response units in FIG. 1 are the same number of lines as in the prior art (four lines).

This voice response device includes a control section 1, a voice memory section 2,
Voice response units 3-1 to 3-4, voice bus 5, and D/A
It includes (digital/analog) conversion sections 4-1 to 4-5 and a line setting section 6.

The voice response units 3-1 to 3-4 receive voice data (voice digital signals) from the voice memory unit according to instructions from the control unit 1.
Read out.

The audio bus 5 uses the first to Nth time slots (N=4 in this embodiment) to the audio response units 3-1 to 3-3.
-4 audio data are allocated in order, audio response unit 3-1
The audio data from ~3-4 is time-division multiplexed, and D
/' Send to A converters 4-L to 4-5.

The D/A converters 4-1 to 4-4 receive and receive multiplexed audio data (audio digital signals) from the audio bus 5.
A corresponding D/A converter converts the audio digital signal into an analog signal and outputs it as audio signals S1 to S4.

The line setting section 6 sets a line to be monitored.

This setting is performed by providing a switch or by using a keyboard from the control unit 1.

The D/A converter 4-5 extracts audio data (audio digital signal) from the time slot corresponding to the line for audio monitoring according to the settings of the line setting unit 6, converts it into an analog signal, and outputs it as an audio monitor signal M1. do. By listening to this audio monitor signal through a speaker or the like, the audio of the audio response units 3-1 to 3-4 can be monitored.

Next, the operation of this embodiment will be explained. The control unit 1
The process from instructing the voice response units 3-1 to 3-4 to output voice and reading data from the voice memory unit 2 to the voice response units 3-1 to 3-4 is the same as in the prior art. Audio bus 5 is 4
It is a single signal line that time-division multiplexes data for each line, and its configuration is shown in FIG. The horizontal axis in FIG. 2 is the time axis, and the time slots are allocated in the order of time slots 1, 2, 3, and 4. Therefore, the voice response section 3-1 is in time slot 1, and the voice response section 3-2 is in time slot 2.
Then, the voice response section 3-3 outputs the data read from the voice memory section 2 to the time slot 3, and the voice response section 3-4 outputs the data read from the voice memory section 2 to the time slot 4. As a result, the D/A converter 4
-1 converts the data of time slot 1 into the D/A converter 4-
2 converts the data of time slot 2 to the D/A converter 4-3.
converts the data of time slot 3 into an analog signal, and the D/A converter 4-4 converts the data of time slot 4 into an analog signal.
The audio signals SL, S2 . S3. Output as S4. Further, the D/A converter 4-5 converts the audio data (audio digital signal) of the time slot corresponding to the line designated by the line setting unit 6 into an analog signal and outputs it as monitor audio as Ml.

Next, to explain the output of this monitor sound, the voice response device is usually installed in a machine room or the like, but the output sound is connected to a speaker installed separately in a place far away from the machine room. Therefore, the operator needs to check the audio being output to each line near the device. The operator determines the line for which the voice is to be monitored, that is, any one of the voice response sections 3-1 to 3-4, and sets it in the line setting section 6. This setting may be performed by providing a switch in the line setting section 6, or may be performed from the keyboard by connecting a keyboard or the like to the control section 1. The line setting section 6 instructs the D/A converting section 4-5 from which time slot data should be extracted based on information set from switches, keyboards, etc. The D/A converter 4-5 converts the designated time slot, for example, the voice response unit 3-1.
The audio data (audio digital signal) is taken out from time slot 1, converted into an analog signal, and outputted as an audio monitor signal M1. The voice monitor signal Ml is input to a speaker installed near the voice response device, allowing the operator to monitor the voice of the set line.

[Effects of the Invention] As explained above, the present invention is provided with an audio bus that time-division multiplexes the digital signals output from each audio response unit, so that even when the number of audio output lines is large, the time slot of the audio bus is All you need to do is increase the multiplexing. therefore,
This eliminates the need for a complicated switching section, simplifies the circuit configuration, and makes it easier to secure signal lines.
