Description

Voice Controlled Radio {The radio controlling the voice}

It is a technology that implements the hands-free function of the radio, and there is a radio hands-free / mouse-free (application number special 1997-031520), but it is equipped with a transmission / reception control button to control the button during transmission and reception.

It is a technology related to a radio that can be used as hands-free by connecting to a mobile phone. have.

An integrated two-way radio (application number 10-2001-0063535) that transmits and receives signals in both directions by separating the frequencies of the transmitter and the receiver is not a radio concept of a transmitter and a receiver of a single frequency single communication channel. Transmission control method using the voice and its apparatus (especially 1993-00264285) relates to the transmission and reception switching method of a vehicle radio, in particular, when the voice is uttered without manually operating the transmission and reception switching button to detect the size of the spoken voice noise In a method of controlling a transmission using a voice in a vehicle radio and a device for allowing direct transmission when it is determined that this is not the case, a method for transmitting and receiving a voice message in a vehicle radio includes: A first step of amplifying with an amplification value of; A second step of rectifying and converting the sound signal amplified in the first step into a DC power source; A third step of generating a reset signal when the sound signal rectified in the second step is larger than the reference power source by comparing the sound signal rectified with the reference power source; And a fourth step of wirelessly transmitting an acoustic signal applied through the microphone by receiving the control signal generated in the third step. According to the technology or claim, the transmission key is turned on when the sound signal is larger than the reference power according to the technology or the claim, and when the sound signal is larger than the reference power, the transmission key is turned on. And when the voice is put on for a while, the transmission key is OFF regardless of the sender's intention and if the user speaks the voice unrelated to the communication contents while receiving the communication contents of the other party, the reception is not performed. There may be problems such as disconnection or transmission and reception, especially due to ambient noise. There have been problems in that malfunctions and initial voice parts are not well transmitted, and control such as channel change and volume control must be controlled manually.

The present invention is not a technology to control the volume of voice that is likely to malfunction due to ambient noise (converts the voice into an electrical signal and is larger than the reference value of the electrical signal, which is smaller than the standard value). The first feature is to control the radio's unique functions such as coordination by voice command, and the second is to recognize and control not the communication sound but the voice control command only when it matches the voice command input in advance among all voices spoken during communication. It is to separate and control only the registered voice (voice control command) from the daily communication contents with the control command, and to control the voice control feature suitable for the one-way communication characteristics of the radio which is differentiated from the existing voice control radio and the existing voice recognition control technology. Control technology.

When comparing the control command registered by the control command input unit that registers the control command voice differentiated from the daily communication contents in order to separate and recognize the daily communication voice and the control command voice spoken by the user in the voice comparator The control commands differentiated by the technical task can be arbitrarily set by the user. However, the voice commands are used to make a specific voice such as 'ready-' in front of the control command or to control the voice words that are not used in the usual communication contents. It is preferable to register as a command, and the control unit input unit and the voice comparator for determining whether or not the voice control command is generated and transmitted are consistent with the voice control unit and the main control unit for controlling the radio when the voice control command is matched. to be.

The present invention is a voice recognition technology to implement a voice control radio that solves the problem that one hand must hold the radio according to communication when receiving the voice of the other party only when transmitting and pressing the transmission key of the radio while the transmission key is released. 1, a microphone 130, a speaker 120, a control command input unit 700, a memory unit 400, a main control unit 600, a voice comparator 800, and a transmitter. 100, the receiver 110, the channel selector 300, the display 200, and the antenna 500.

The microphone 130 receives the voice and converts the voice into an electrical signal, and the speaker 120 reversely converts the electrical signal into the voice.

The memory unit 400 stores a control program, a voice memory, control data, and the like.

The control command input unit 700 includes a voice control command input key 710, a voice data analyzer 720, a voice data converter 730, and a control data generator 740. The control command input unit receives a voice control command input key after the first purchase of a voice control radio, and receives a voice control command input through a microphone on / off command input, a channel input command input, and a radio application special application command. After the control command and the input voice are corresponded one-to-one through 720, the voice data converter 730 is converted into voice data, and the voice control command is stored in the memory unit through the control data generator.

The main control unit 600 operates the radio by voice using the voice control command generated after the initial purchase of the voice control radio and performs overall control of the radio. The voice comparison unit 800 compares the voice control command with the voice of the same voice during voice transmission and provides control information for controlling the voice control radio through the main control unit when the voice is matched.

The display unit 200 is composed of an LCD screen and red and green LEDs. The LCD screen displays various messages and channel states, and is composed of a red LED indicating a transmission state and a green LED indicating a reception state.

The transmitter 100, the receiver 110, the channel selector 300, and the antenna 500 implement functions of a general radio.

The operation of the voice control radio having the above configuration will be described with reference to FIG. 2, which is a flowchart illustrating an example of registering a voice control command of a terminal according to an embodiment of the present invention.

When the user presses the voice control command input key 710 after the initial purchase, the display unit displays a message 'Please enter the transmit key ON voice' and the user inputs the voice through the microphone. For example, 'SEE ON', 'Start', 'On' are examples of commands according to the transmission key ON.

When the voice is input by pressing the voice control command input key again, in the next step, the display unit displays the message 'Please enter the transmit key OFF voice' and the user inputs the corresponding voice such as 'over' through the microphone.

When the voice is input by pressing the voice control command input key again, in the next step, the message 'Enter the volume up voice' is displayed and the user inputs the corresponding voice such as 'Ready-Volume up' through the microphone.

When the voice is input by pressing the voice control command input key again, in the next step, the message 'Enter the volume down voice' is displayed and the user inputs the corresponding voice such as 'ready-volume down' through the microphone.

Press the voice control command input key again to input the voice. In the next step, the display shows the message 'Please select the channel selection voice' and the user can display the 'channel one', 'channel two', and 'channel one' through the microphone. , Input the corresponding voice such as 'channel to'.

The input voice command is one-to-one correspondence between the control command and the input voice through the voice data analyzer 720 and then converted into voice data by the voice data converter 730 and then the voice control command through the control data generator 740. Will be stored in the memory.

In the same manner as described above, the unique input of each radio and the re-entry of voice control commands are repeated.

If the voice comes out of the contents of the call, which is not a command to control the radio during a normal radio call, the main control part of the voice control radio can be mistaken for a radio control command to perform radio control. You can prevent errors by inserting a special note such as.

For example, the actual use through the radio registered with the voice control command registered as the registration example,

When wireless communication is required during operation, when the voice "SEE ON" is sounded, the main control unit of the voice control radio performs the same control as pressing the radio transmission key and communicates without holding the key by hand.

When the user wants to listen to the other party's communication after saying what he wants to say, say "SEE OFF". The main control unit of the voice control radio receives the other party's voice by performing a control to release the transmission key.

When it is necessary to change the channel, if it is called "channel to", the main control unit controls to configure the communication path by changing channels.

However, if the word "channel to" is spoken regardless of the voice control command during the daily call, the channel may change. Therefore, it may be desirable to use commands that are not commonly used in everyday life (eg, ready-channel to).

In addition, there is an LED and a display unit for transmitting and receiving status indication and channels for smooth use, and a switching sound (eg a beeping sound) can be inserted when transmitting and receiving.

When describing the control command input unit and the main control unit in detail,

The voice control command input key 710 of the control command input unit allows the user to press the voice control command input key after the first purchase and utter a control command voice through a microphone to store the voice in the voice memory of the memory unit.

The voice data analyzer 720 converts the voice into an electrical signal. At this time, the signal is digitalized through an A / D converter to form voice data.

The voice data converter 730 analyzes the syllable unit and converts the voice data into the voice command unit.

The control data generator 740 generates voice control commands by one-to-one correspondence of the voice data generated through the voice data converter with the corresponding control of the main controller.

The voice comparison unit 800 compares the voice of the voice control command with the same voice in the voice transmitted during the communication, and provides control information to control the voice control radio through the main control unit if the voice control command matches.

The main control unit performs the corresponding control when the matched voice control command is input through the voice comparator after the operation of the voice control radio.

The voice control radio which realizes complete hands-free radio by controlling the operation of the radio by the voice after registering the voice recognition to the voice control radio by the voice control radio to communicate with the everyday voice using the voice control. In order to control the radio by activating the registered voice control command, the main control unit controls the voice control radio according to whether the voice comparator compares the voice of the sender's daily voice word with the voice control command. .
