Recording a voice input through the microphone;

Searching for the specific receiver set;

And converting the recorded voice into a wireless signal and transmitting the same to a specific receiver.

1 to 7 will be described in detail with reference to the flowchart of Figure 7 the voice recording control method in the radio having a voice function according to the present invention.

First, when the voice recording function is set through the automatic / manual recording setting key 125 of the radio 10 in step 201, the controller 120 of the radio drives the voice sensing unit 131 in step 202. The detector 131 checks whether there is a voice signal input through the microphone. When the voice signal is detected through the voice detector 131 in step 202, the controller 120 records the voice input through the microphone in the voice recorder 119 in step 2032. Thereafter, the control unit 120 searches for whether a specific receiving side to which the recorded voice is to be transmitted is designated in step 204, and if there is a specific receiving side designated in step 205, the corresponding receiving side, for example, in Table 1 above. As mentioned above, the recording voice is transmitted to a remote radio connected through a specific radio, a mobile phone, another radio, a computer, and an internet network. In this case, the control unit 120 amplifies the recorded voice modulated by the transmission frequency signal corresponding to the receiving side information and transmits the radio signal through the duplexer 111 and the antenna as a radio signal. When the manual voice recording function is set, the receiving side to receive the recorded voice may transmit the recorded voice to the corresponding receiving side after the voice is selected by the user after the voice is recorded, and the automatic voice recording function is set. In this case, the recording voice may be automatically transmitted to the receiver in advance. If the voice recording function has elapsed in step 206 or if the cancellation is selected by the user, the voice recording function ends and the voice recording control operation according to the present invention ends. If the voice recording setting is not terminated, the procedure proceeds to step 202. After that, the operation is repeated sequentially.

On the other hand, if the receiving side to receive the recording voice is a specific directory of the computer, the radio 10 sends the recording voice to the computer 30 by the relay of the charger 20, the computer TTS (Text To After converting to text information using Speech) function, save it in the specified directory.

In addition, when the receiving side to receive the recording voice is a remote walkie talkie 70 connected to the remote computer 50 connected through the computer 30 and the Internet network 40, the recorded voice delivered to the computer again. The remote computer 50 is transmitted to the remote computer 50 through the Internet network 40, and the remote computer 50 transmits it to the remote radio 70 as a radio signal by the relay of the charger 60. The recorded voice may be transmitted through the speaker of the remote computer 70.

In the detailed description of the present invention described above, specific embodiments have been described, but various modifications are possible without departing from the scope of the present invention. Therefore, the scope of the present invention should not be limited to the described embodiments, but should be defined not only by the scope of the following claims, but also by the equivalents of the claims.

As described above, the present invention provides a radio having a voice recording function, and if necessary, can record a voice according to automatic or manual setting, and send it to a specific receiving side of a remote to check the recording voice at a remote place. There is an advantage to increase utilization.
