Sign Language Volume Control Device and Method

The present invention relates to an apparatus and method for automatically controlling a sign language volume by ambient noise in a telephone.

Typically, the handset of the telephone is generated according to a preset volume when a telephone call is made. However, the occurrence of the sign language is causing a lot of difficulties because it can not actively cope with the surrounding environment.

For example, when the loudness of the handset is set, when the call is made in a quiet environment, the handset may be loudly heard and the contents of the call may be known to others. If the volume was too loud, the auditory cells were excessively stimulated. In addition, when the sign language volume is set low, the user could not grasp the contents of the call when the call is made in a noisy area around the subway. Therefore, the user often calls with anger.

In the above situation, despite the adjustment of the sign language volume, the same problem occurs when the received voice is received small or loud.

For example, if a voice received is small due to a problem in the system or a caller's terminal, the call cannot be understood. In addition, when the received voice is largely received, there is a problem that the contents of the call are known to others.

Accordingly, it is an object of the present invention to provide an apparatus and method which is generated by automatically adjusting the hydration volume by ambient noise.

Another object of the present invention is to divide the measured noise into three stages to provide a method for automatically adjusting the hydration volume according to each of the above steps.

1 is a block diagram of a wireless terminal according to an embodiment of the present invention.

The controller 120 of the wireless terminal controls the overall operation of the wireless terminal. The key input unit 110 includes a plurality of numeric keys and function keys for performing various functions, and outputs key data to the controller 120 by an external operation. The memory 100 is composed of a ROM storing an operating program, an electrically programmable EEPROM and a RAM. The volume measuring unit 130 measures ambient noise input through the microphone 160. When the microphone 160 converts the ambient noise into an electrical signal and outputs the noise, the volume measuring unit 130 measures the noise through the converted signal. In addition, by measuring the voice signal input through the RF unit 180 to measure the volume of the received voice. The display unit 140 is a display device such as a liquid crystal display (LCD). The display unit 140 displays the state of the wireless terminal or the progress of the program under the control of the controller 120. The microphone 160 receives the voice and converts it into an electrical signal and transmits the signal to the amplifier 190. The speaker 170 outputs the voice output through the amplifier 190. The RF unit 180 is controlled by the controller 120 and transmits a signal output from the amplifier 190 to the base station. In addition, the RF unit 180 converts the wireless signal received through the antenna into a desired signal and outputs it. The amplifier 190 modulates the voice signal input from the microphone 160 and converts the voice signal into voice data. The amplifier 190 demodulates the voice data input from the RF unit 180 into a voice signal and outputs the voice signal through a speaker. That is, the amplifier 190 amplifies the signal input and output through the speaker 170 and the microphone 160, or amplifies the voice signal and various transmission and reception data output through the RF unit 180. The sign language volume controller 150 adjusts the volume of the voice output to the speaker 170 under the control of the controller 120.

2 is a control flowchart for automatically adjusting a sign language volume according to an embodiment of the present invention.

In step 200, the controller 120 measures the ambient noise input through the microphone 160 through the volume measuring unit 130. The measured noise may be shown in Table 1 below.

noise Noise [dB] Prize 80 or more medium 40 to 80 Ha 40 or less

The measurement of the noise may be measured for a certain time or a certain number of times during a certain time. For example, it can be measured for 3 seconds or 3 times at 2 second intervals for 1 second. In step 210, the controller 120 determines whether a call path is connected. If the line is connected, proceed to step 220; otherwise, continue to wait for the line to be connected. In step 220, the controller 120 determines whether the noise is “up” according to the noise measured in step 210. That is, for example, when the measured noise as shown in Table 1 is 80 decibels or more proceeds to step 230, and if it is 80 decibels or less proceeds to step 240. In step 230, the control unit 120 outputs a sign language volume “up” to the speaker 170 through the sign language volume control unit 150. In step 240, the controller 120 checks whether the volume of the noise is about 40 to 80 decibels. If the noise is above 40 decibels, go to step 250; if it is below 40 decibels, go to step 260. In step 250, the controller 120 outputs a sign language volume to the speaker 170 through the sign language volume controller 150 as "medium". In step 260, the control unit 120 outputs the sign language volume to the speaker 170 as "low" through the sign language volume control unit 150. In step 270, the controller 120 checks whether the call path is disconnected. If the call is lost, end the program; otherwise, proceed to step 280. In step 280, the controller delays the time for a predetermined time and then returns to step 210. In other words, during the call, the received volume is continuously measured and the volume is adjusted.

3 is a control flowchart for automatically adjusting a sign language volume according to another embodiment of the present invention. 3 is a flow chart of adjusting the received volume by measuring the received sign language volume. First, in step 300, the controller 120 checks whether a call path is connected. If the call path is connected, proceed to step 310; otherwise, continue checking whether the call path is connected. In step 310, the controller 120 measures the volume of the voice received through the RF unit 180 through the volume measuring unit 130. For example, it is shown in Table 2 below.

Sign Language Volume Volume of incoming voice [dB] Ha 80 or more medium 40 to 80 Prize 40 or less

The volume measurement of the received voice may be measured for a predetermined time or a predetermined number of times for a predetermined time. For example, it can be measured for 3 seconds or 3 times at 2 second intervals for 1 second. In step 320, the controller 120 determines whether the sign language volume is “up” according to the volume of the received voice measured in step 310. That is, for example, when the measured noise as shown in Table 1 is 80 decibels or more, the process proceeds to step 330, and if it is 80 decibels or less, the process proceeds to step 340. In step 330, the control unit 120 adjusts the volume through the sign language volume control unit 150 to output the sign language to the speaker 170 as "low". In step 340, the controller 120 checks whether the measured noise is about 40 to 80 decibels. If the noise is above 40 decibels, proceed to step 350; if it is below 40 decibels, proceed to step 360. In step 350, the control unit 120 adjusts the volume through the sign language volume control unit 150 to output the sign language to the speaker 170 as "middle". In step 360, the control unit 120 adjusts the volume through the sign language volume control unit 150 and outputs a sign language sound to the speaker 170 as "up". In step 370, the controller 120 checks whether the call path is disconnected. If the call is lost, end the program; otherwise, proceed to step 380. In step 380, the control unit 120 delays a predetermined time and then returns to step 310.

4 is a control flowchart for automatically adjusting a sign language volume according to another embodiment of the present invention. In FIG. 4, both the ambient noise and the received sign language volume are measured to adjust the sign language volume in consideration of two causes.

First, in step 400, the controller 120 measures the volume of the ambient noise input through the microphone 160 through the volume measuring unit 130. In step 410, the controller 120 checks whether the call path is connected. If the call is connected, go to step 420; otherwise, continue checking to see if the call is connected. In step 420, the controller 120 measures the volume of the sign language volume received through the RF unit 180 through the volume measurement unit 130. The noise measurement in step 400 and the volume measurement of the received voice in step 420 may be measured for a predetermined time or a predetermined number of times for a predetermined time. For example, it can be measured for 3 seconds or 3 times at 2 second intervals for 1 second. In step 430, the controller 120 checks whether a sign language volume value is different as shown in Table 3 below.

Receive Sign Language Volume Noise [dB] 10 20 30 40 50 60 70 80 90 120 . . . 10 medium medium Ha Ha Ha Ha Ha Ha Ha Ha . . . 20 medium medium medium Ha Ha Ha Ha Ha Ha Ha . . . 30 medium medium medium medium Ha Ha Ha Ha Ha Ha . . . 40 Prize medium medium medium medium Ha Ha Ha Ha Ha . . . 50 Prize Prize medium medium medium medium Ha Ha Ha Ha . . . 60 Prize Prize Prize medium medium medium medium Ha Ha Ha . . . 70 Prize Prize Prize Prize medium medium medium medium Ha Ha . . . 80 Prize Prize Prize Prize Prize medium medium medium medium Ha . . . 90 Prize Prize Prize Prize Prize Prize medium medium medium medium . . . 120 Prize Prize Prize Prize Prize Prize Prize medium medium medium . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . .

Referring to Table 3, it can be seen that the sign language volume value to be output is proportionally increased according to the noise, and the volume of the received voice is inversely proportional. In step 440, the control unit 120 adjusts the sign language volume to “up” through the sign language volume control unit 150 and outputs the signal to the speaker 170. In step 450, the controller 120 checks whether a sign language volume value is present. If the sign language volume value is busy, go to step 460; otherwise, go to step 470. In step 460, the control unit 120 adjusts the sign language volume to “middle” through the sign language volume control unit 150 and outputs the signal to the speaker 170. In step 470, the control unit 120 adjusts the sign language volume to "down" through the sign language volume control unit 150 to output the speaker 170. In step 480, the controller 120 checks whether the call path is disconnected. If the call is disconnected, the operation for adjusting the handset volume is terminated. In step 490, the controller 120 delays the time for a predetermined time and then proceeds to step 410.

2, 3, and 4 divided the noise into three stages, but this classification can be easily divided into any stage. In addition, in the present embodiment, the wireless terminal is taken as an example, but it is found that the present invention can be applied to a communication terminal such as a mobile phone and a general telephone.

Meanwhile, in the detailed description of the present invention, 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 generates a sign language by actively adjusting a sign volume according to ambient noise and a received sign volume, thereby preventing an unnecessary loud sign volume from being made known and making a call. The volume is so low that the user can not understand the call can solve the problem.
