Abstract

PURPOSE:To resolve the increase of the cost, the disadvantage of handling, etc. and executing various remote operations or the like with voice, by incorporating a voice recognizing device in a microphone body and obtaining directly a voice recognition signal from the microphone. CONSTITUTION:First, a voice is inputted by a mike unit 9 and subjected to impedance conversion into low impedance by a mike amplifier 10. Next, it is selected whether a voice recognition signal (digital signal) or a voice signal (analog signal) should be obtained by a switch 11, and the output is obtained from a terminal A or B. A simple voice recognizing device is added to the microphone side, and it is possible that the voice recognition signal and the voice signal are selected by the switch 11, and it is possible that the digital signal is transmitted with a wire to issue an instruction to the body. Further, the malfunction due to noise or the like is reduced, and various remote operations or the like are executed with voice, and the increase of the cost, the disadvantage of handling, etc. are resolved.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a microphone device useful in, for example, educational systems.

Configuration of conventional example and its problems Figure 1 shows a conventional speech recognition device. 1 is a microphone unit, 2 is a microphone amplifier, 3 is a 4-octave filter with a 6-teil filter, and 4 is a filter after rectification and smoothing. 6 is an integrator, 6 is a multiplexer (MPX) for taking out each channel and sending it to an AD converter, 6 is an AD converter, 7 is a CPU, and s is a memory.

Next, the operation of the conventional speech recognition device will be explained. 1st
In the figure, a real analog input is obtained from microphone unit 1, is added to amplifier 2 with pre-emphasis, and 16
After frequency division with a six-octave filter 3, the signal is rectified and smoothed with an integrator 4 to obtain a power spectrum. After that, multiplexer 5 sequentially converts AD converter 6.
The signal is sent to the CPCJ7, AD-converted, and sent to the CPCJ7, where the digital amount corresponding to the time change of the filter filter is compared with the text in the memory 8, voice recognition is performed, and an identification signal is sent.

However, in the above-mentioned conventional configuration, noise or erroneous recognition may occur between the input from the microphones C, 1, and 1 to the speech recognition device, and the algorithm for simple recognition (for example, numbers) cannot be used within a small space. However, the inconvenience of having the microphone and voice recognition device separated into two parts was a problem in the application field of gods, and the problem was that it could not be popularized due to cost issues.

OBJECT OF THE INVENTION The present invention eliminates the problems of the conventional technology, and eliminates the cost increase and inconvenience of handling.
The purpose is to obtain a voice recognition signal directly from a microphone and enable various remote operations and hands-free operations using voice.

Structure of the Invention In order to achieve the above-mentioned object, the present invention incorporates the above-mentioned voice recognition device into the microphone main body, thereby eliminating misrecognition caused by noise etc. that occurs between the microphone and the above-mentioned voice recognition device, and improving the accuracy of voice input from the microphone. The aim is to accurately send out a recognition signal (digital signal).

DESCRIPTION OF EMBODIMENTS The configuration of an embodiment of the present invention will now be described with reference to the drawings. In FIG. 2, there is a 9-microphone unit, and this microphone unit has 10 microphone amplifiers.
The entire line is connected to the switch 11. This switch 11 may be implemented in either electrical or mechanical manner. Further, the signal can be directly led to the output terminal B by the switch 11, and can be led to the output terminal A via the voice recognition section (12 to 17).

Next, the operation of the above embodiment will be explained. In FIG. 2, the microphone unit 9 inputs audio, and the microphone amplifier 1
0 means impedance conversion, low impedance,
A voice recognition signal (digital signal) is activated by the switch 11.
output from terminal A and terminal B respectively.

In this actual case, a simple voice recognition device was attached to the microphone side, so that the voice recognition number and voice signal could be selected by switch 11, and the digital signal was transmitted by wire to the main unit. Since commands can be issued, there is an advantage that malfunctions due to noise etc. can be further reduced.

Effects of the Invention The present invention, configured as described above, provides the following effects.

a. Accurate commands can be transmitted because the microphone itself converts it into a digital signal.

b Commands to the main unit and audio signals (analog signals) can be selected with a simple switch operation, so it can be used for various consumer devices (music selection commands to the eXX Karaoff loudspeaker, audio input to the '11f telephone dial, etc.). 0 that can enable hand-free operation
