Description

DETAILED DESCRIPTION OF THE INVENTION (a+) Technical Field of the Invention The present invention relates to a voice response device, and more particularly to a new voice response device capable of providing voice responses that are easy to hear even in a noisy environment.

(bl Prior Art and Problems Recently, voice response devices that output voice messages to guide input operations have been used in vending machines and automatic bank transaction devices.However, conventional voice response devices Since only high-pitched sounds are generated, the output voice message has a drawback that it is difficult to hear in the surrounding noise environment, that is, within the high-pitched noise.

FC+ Purpose of the Invention The present invention solves the conventional situation as described below, by making it possible to output a voice message in a range that corresponds to the surrounding noise situation. The object of the present invention is to provide a new voice response device that outputs high-frequency sounds within a range of noise.

(d) Structure of the Invention In order to achieve the above object, the present invention provides a first voice storage means that stores a plurality of words or words in a high-pitched voice, and a first voice storage means that stores a plurality of words or words in a low-pitched voice. The second one? ,? A voice memory T stage, a means for analyzing the frequency of surrounding noise, and an analysis output indicating a low frequency of the noise analysis means, the first voice memory device is inputted into the first voice memory T stage. j, the second audio record A selects the first stage according to the analysis output indicating the number, and the input contents of the first input stage A responds to the input content of the selected voice memory in the membrane. Means for selecting and IRing audio signals;
A voice response device comprising means for providing the following information is proposed.

(M) Embodiments of the invention Hereinafter, embodiments of the invention will be described in detail with reference to the drawings.
Ili, I'll explain.

The drawings show one embodiment of the invention.
If you look at the drawing number for C3, 1 is the microphone that inputs the surrounding noise, and 2 is the output peak number of the microphone 1 cophone.
'iiF amplifier, 3, is the designated frequency of the amplified noise signal, for example a frequency below 2Kilz and 1. two sets of bunt-pass filters, each passing a frequency of . 1
, which is a different frequency filter. Here, f in the explanation
J2 Yigami, 2Kllz1. The frequency below μ is the low frequency, 2
Frequencies above Kllz are called high frequencies. In the figure, 4 is a frequency analysis circuit that analyzes the frequency signal from the filter 3 and selectively outputs a digital signal indicating the low frequency and a digital signal indicating the high frequency; It is an input means consisting of operation keys 51 to 58 and a switch circuit 59 for outputting key-in signals thereof, and is the input key of a cash dispensing machine or the like. In addition, 6 is a first voice memory that collects 8 types of voice messages in response to the 508 type 0 input operations of the input means as a voice signal (digital signal) of a female high-pitched voice, and 7 is the same 8 types of responses. a second voice memory that collects voice messages as a voice signal (digital signal) of a man's low-range voice; 8 is the frequency analysis circuit 4;
When the output signal is a digital signal indicating a low frequency, the first audio memory 6 is selected, and when the digital signal indicating a high frequency is input, the second audio memory 7 is selected.
This is a memory selection circuit that selects. Therefore, at the time of input operation, if there is low-frequency noise in the surroundings, a response message signal with a female voice is selected, and in a high-frequency noise condition, a response message signal with a male 411 voice is selected.

Further, 9 is an address for reading the key-in message 11j of the input means 5 and reading out the response voice message message corresponding to the input operation from the selected voice memory 6 and 7. Although the display circuit 10 is not necessarily required, it converts the voice message read from the voice memory into a voice message.
・Buffer memory for storing J at −・, 11 is a D-Δ converter which converts the audio message signal read from the J buffer memory 10 into an audio signal (without exception); 1
Reference numerals 2 and 13 are amplifiers for amplifying the analog audio output and speakers for outputting audio, and 14 is a circuit for setting the operation timing of each circuit.

Now, it is assumed that the operation key 51 of the input means 5 is pressed in the surrounding environment or in a low-frequency noise situation. In this case, the first address F of the first voice memory 6 where the female voice message version-J was collected is selected, and the [dark jl
The message "Please enter the F number" should be emitted from the speaker 13 by the sound of "f(+". Therefore, according to this voice message in the opposite range of the noise range,
The content of the message can be easily heard.

In addition, each of the above-mentioned voice memories 6.7 may be a word collection instead of a t3 hazuki. However, this modification requires a means of editing the 11 spoken words into a desired message format.

(el) Effects of the Invention As is clear from the explanation in Section 12, according to the voice response device of the present invention, when the surrounding noise is low frequency, it responds with a high-pitched female voice message; Since the system responds with a low-pitched male voice message, the contents of the response message can be known with certainty.Therefore, the present invention can be extremely useful when applied to operation guidance means for vending machines, automatic bank teller machines, etc. be.
