Abstract

PURPOSE:To simplify a response operation at an incoming call by designing a device so that a loudspeaker reply key is turned on with the input of a specific voice. CONSTITUTION:A special voice (a) is inputted in advance from a microphone 1 and stored in a storage section 4 via a voice amplifier section 2 and an A/D converting section 3. An incoming detection section 6 outputs a sound signal at an incoming call and the voice same as the voice stored in the storage section 4 is inputted to the microphone 1. The voice is inputted to a comparison/ recognition section 5 as the present sound signal. The section 5 inputs the voice data stored in the storage detection 4, the both are compared and recognized, and when the both are coincident with a prescribed level or over, a coincidence signal is outputted. In outputting the said incoming signal and the coincidence signal, a control section 8 outputs a control signal (c) to turn on the loudspeaker reply key according to the logical level of an AND circuit 7.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a loudspeaker telephone, and more particularly to a voice recognition automatic response telephone that can automatically go off-hook by voice recognition.

[Conventional technology]

In conventional loudspeaker telephones, in order to answer an incoming call, the user must lift the handset or manually press a loudspeaker response button.

[Problems to be solved by the invention] Therefore, in the conventional loudspeaker telephone, when answering an incoming call,
When making a call using a handset, it is necessary to lift the handset, and when making a hands-free call, it is necessary to press a loudspeaker response button, which is a time-consuming operation. there were.

[Means for solving problems]

In order to solve these problems, the present invention provides a microphone into which audio is input, an A/D converter for digitizing the audio signal output from the microphone, and an A/D converter for digitizing the audio signal output from the microphone. A storage unit that detects characteristics of the output digital signal at the time of writing and stores it, and a comparison/recognition unit that compares the data output from this storage unit with the digital signal output from the A/D conversion unit at the time of recognition. , an incoming call detection section that outputs an incoming signal when an incoming call arrives, and an incoming call detection section that outputs an incoming signal,
and a control section that outputs a control signal to automatically turn on a loudspeaker response button when the data output from the storage section and the digital signal output from the A/D conversion section match. It is.

[Effect]

In the present invention, a loudspeaker response button is turned on by inputting a specific voice.

〔Example〕

An embodiment of the voice recognition automatic response telephone according to the present invention is shown in the figure. In the figure, 1 is a microphone that converts input audio a into an audio signal, 2 is an audio amplification unit that amplifies the audio signal output from the microphone 1, and 3 is a digital audio amplification signal that is output from the audio amplification unit 2. 4 is a storage unit that detects the characteristics of the digital signal output from the A/D conversion unit 3 at the time of writing and stores it; 5 is an A/D conversion unit that converts the audio data output from the storage unit 4 when recognizing it; A comparison/recognition unit that compares the digital signal output from the D conversion unit 3 and outputs a matching signal when they match; 6 is an incoming call detection unit that outputs an incoming signal when an incoming call arrives; 7 is an incoming call detection unit An AND circuit that takes the AND of the incoming signal output from 6 and the coincidence signal output from the comparison/recognition unit 5; 8 is a loudspeaker response button when the logic level output from the AND circuit 7 is "1"; This is the control unit that turns on the

Next, the operation of the apparatus configured as described above will be explained. In order to perform an automatic voice response when an incoming call is received, a specific voice a such as "Hi", "
The voice "mojimoji" is input from the microphone 1, and the voice amplifying section 2. The signal is input to the storage section 4 via the A/D conversion section 3 and stored therein.

When there is an incoming call, the incoming call detecting section 6 detects the incoming call and outputs an incoming signal, and at the same time inputs the same sound as the sound previously stored in the storage section 4 into the microphone l.

The voice a input to the microphone 1 is transmitted to the voice amplifying section 2 and the A/D.
The signal is inputted to the comparing/recognizing section 5 as a current audio signal via the converting section 3. The comparison/recognition unit 5 inputs the audio data stored in advance in the storage unit 4, compares and recognizes this audio data with the current audio signal, and issues a one-lose signal when the two match at a certain level or higher. Output.

An incoming call signal is output from the incoming call detection unit 6, and the comparison/recognition unit 5
When a match signal is output from the logical product circuit 7, the AND circuit 7 outputs a signal of logic level “1” to the control unit 8. When a signal with an AND level of "1" is input, the control section 8 outputs a control signal C for turning on the loudspeaker response button.

In this way, when an incoming call is received, the amplified response button can be turned on simply by inputting a certain specific voice a into the microphone 1, and a hands-free call can be made.

〔Effect of the invention〕

As explained above, the present invention digitizes the audio signal output from the microphone into a digital signal, detects the characteristics of this digital signal when writing, stores it as audio data, and converts this audio data into the digital signal when recognizing it. To automatically turn on a loudspeaker response button by comparing and recognizing an incoming call and outputting a control signal when an incoming call is received and an incoming call signal is output, and when the audio data and the digital signal match. This allows you to answer an incoming call simply by inputting a specific voice into the microphone, which has the effect of eliminating the need for operations such as lifting the handset or pressing a loudspeaker response button.
