Description

Wireless Ear MIC equipped with the voice control function for two way radios}

The present invention is a problem that must hold the radio with one hand when communicating as the radio receiver receives the voice of the other party only while transmitting while pressing the push-to-talk button of the radio and releasing the push-to-talk button. The present invention relates to a wireless ear microphone for a radio having a voice control function using voice recognition technology to implement a hands-free function for a radio.

The present applicant has conceived the radio ear microphone for radio mounting as Utility Model Registration No. 0309723 (hereinafter referred to as a declaration).

In the draft, connect the base unit to the radio's earphone jack, connect the base unit and the handset by wireless communication, and push button S / W on the front of the base to be mounted on the waist. This paper describes a wireless ear microphone for radios that allows users to use both hands freely by pushing the push button S / W. The present invention is more complete by controlling the transmission and reception using voice recognition technology rather than push button S / W. Wireless ear microphones for radios with voice control for hands-free function are described.

In order to use the radio in a more convenient way, a wired ear microphone was connected to the radio. Since the wired ear microphone and the radio are connected by wires, they are not aesthetically pleasing, and there is a problem of limiting the user's activity. In the process of using the cable, the cable is easily pulled or twisted, causing a breakage (wiring phenomenon). In order to transmit, there is also the hassle of using one hand.

Also, to solve the trouble of using one hand, instead of pressing a switch, a conventional VOX (Voice activated Transmission) function is used. The VOX function is a system that detects the volume of the spoken voice and transmits it when voice is spoken without manually manipulating the PTT button (transmission / reception button). When the sound signal is bigger than the reference power by comparing the sound signal with the reference power supply, turn on the transmission key to turn on the error and the loudness reference level according to the loudness of the ambient noise. Irrespective of the intention of the sender, the transmission key is turned off, and if the user utters a voice unrelated to the communication contents while receiving the communication contents of the other party, the reception may be interrupted or the transmission and reception may be irrelevant regardless of the sender's intention. A malfunction may occur due to the noise of the user, and when the user talks loudly, the voice may be transmitted as it is through the microphone.

An object of the present invention for solving the problems of the prior art as described above, is to enable the radio user to use both hands freely when using the radio by using a voice recognition technology and a wireless transmission and reception technology.
