The present invention relates to an answering machine, and more particularly, to an apparatus and method for detecting and recording only a voice signal having a valid size by detecting a valid sound of a predetermined size or more when recording a message.

A general answering machine automatically sends outgoing message (Out Going Message, OGM) to the other party when ringing is detected from the outside when setting the outgoing mode, and inputs a voice signal corresponding to the OGM. Speak a telephone that you record and provide to the user.

In the case of recording the OGM using a conventional answering machine, the recording was unconditionally recorded until the recording stop key or the set recording time elapsed regardless of the volume of sound provided from the user.

In the conventional automatic answering machine, when the OGM is recorded, even if the voice input from the user is small, it is recorded as it is. Therefore, when there is a call request from the outside under the automatic answering mode, there is a problem that communication is not properly communicated to the other party. .

Accordingly, an object of the present invention is to provide an apparatus and method for detecting a level of a voice signal input during OGM recording in an answering machine and recording only the input voice signal when a signal higher than a reference level is input.

Another object of the present invention is to provide an apparatus and method for stopping recording of a message and displaying an error when a voice signal having a reference level or less at the time of OGM recording is input from an answering machine.

The present invention provides a rectifier for rectifying a voice signal input from an external microphone, a comparator for comparing the rectified voice signal with a predetermined reference signal, and a level changing unit for changing a level of the reference signal. Recording in the OGM when the voice signal input from the microphone is greater than or equal to the level of the reference signal, and when the voice signal is less than the level of the reference signal, stops OGM recording and then deletes the already recorded OGM. And an error message is displayed.

Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

The block diagram of the answering machine for carrying out the present invention is shown in FIG. Referring to the configuration of the answering machine with reference to Figure 1, the CPU 110 controls the overall operation for performing the function provided in the telephone with the answering machine 142. The call circuit unit 112 is connected to the telephone line CO through the interface unit 114, and receives and transmits and receives a control signal CS3 of the CPU 110 or a voice reproduced and stored by the answering machine 142. Connect the signal to the corresponding part. The interface unit 114 includes a hook switch, and forms a telephone tuft under the control of the CPU 110. The codec 116 is connected between the call circuit unit 112 and the DSP unit 118 and converts an analog signal into a digital signal and a digital signal into an analog signal according to the control signal CS2 of the CPU 110. In addition, the DSP unit 118 converts the digital signal input from the codec 116 according to the control signal CS1 of the CPU 110 into digital data by converting the digital signal into binary data and converting the digital data into digital data. Output to the used voice memory 120. In addition, the DSP unit 118 reads numerical data stored in the voice memory 120 under the control of the CPU 110, and outputs the digital signal process to the codec 116. The voice memory 120 stores binary data provided from the DSP unit 118, and reads out data required from the DSP unit 118. The answering machine 142 is composed of a DSP unit 118, a codec 116 and a voice memory 120. The DTMF generation unit 122 receives the control signal CS4 of the CPU 110 and outputs a DTMF signal corresponding to the key data input from the key input unit 128 to the call circuit unit 112. The pulse generator 124 receives the control signal CS5 of the CPU 110, generates a pulse signal, and outputs the pulse signal to the call circuit 112. The display unit 126 displays the operating state of the answering machine according to the control of the CPU 110. The key input unit 128 has a key matrix composed of a plurality of keys, and provides key data according to the key input to the CPU 110. The memory 130 stores a control program for the CPU 110 to perform control and data for performing a function. The speaker 132 converts an electrical voice signal provided from the call circuit unit 112 into an audio signal of an audible sound and outputs it to the outside. The microphone 134 converts an audio signal of an audible sound provided from the outside into an electrical voice signal and provides it to the call circuit unit 112. The rectifier 136 rectifies the voice signal input through the microphone 134 and outputs it to the comparator 138. The comparator 138 receives the rectified voice signal from the rectifier 136 and compares the level of the input voice signal with the level of the reference signal. The level changing unit 140 changes the level of the signal which becomes the reference signal in the comparator 138.

2 is a control flowchart according to the present invention, when the input of the OGM recording key is detected, switching to the OGM recording mode, comparing the level of the input voice signal with the level of the reference signal, and If the level is greater than the level of the reference signal, the process of recording the input voice signal with the OGM until the recording stop key or the set recording time elapses; and if the level of the input voice signal is smaller than the reference signal, OGM recording Stops, erases the stored OGM and displays an error.

Therefore, an embodiment of the present invention will be described in detail with reference to FIGS. 1 and 2.

The CPU 110 determines whether the OGM recording key is input from the key input unit 128 in step 210. When the OGM recording key is input in step 210, the CPU 110 proceeds to step 212 to switch to the OGM recording mode. After switching to the OGM recording mode, the CPU 110 determines whether a voice signal is input through the microphone 134 in step 214. When the voice signal is input, the process proceeds to step 216 where the CPU 110 determines whether the voice signal input from the microphone 134 is a valid signal larger than the reference signal.

In operation 216, the voice signal input from the microphone 134 is rectified through the rectifier 136 and provided to the comparator 138. The comparator 138 compares the level of the rectified voice signal provided from the rectifier 136 with the level of the reference signal set by the level changing unit 140. When the level of the voice signal is compared with the level of the reference signal, the comparator 138 provides the CPU 110 with a first signal corresponding thereto. Then, the CPU 110 receives the first signal from the comparator 138 and determines the input voice signal as a valid signal. However, when the comparator 138 compares the level of the voice signal to be smaller than the level of the reference signal, the comparator 138 provides the CPU 110 with a corresponding second signal. Then, the CPU 110 receives the second signal from the comparator 138 and determines the input voice signal as an invalid signal.

If the voice signal input in step 216 is determined to be a valid signal, the CPU 110 proceeds to step 218 and stores the input voice signal as an OGM. At this time, the CPU 110 controls the call circuit unit 112 to connect the voice signal input from the microphone 134 to the codec 116. The codec 116 converts an audio signal provided from the call circuit unit 112 into a digital signal and provides it to the DSP unit 118. The codec 116 converts the digital signal input to the DSP unit 118 into a digital signal and converts it into binary data. To store in the OGM registration area of the voice memory 120. In operation 220, the CPU 110 detects whether the recording stop key is input from the key input unit 128. In step 222, it is determined whether the set recording time has elapsed from the internally provided timer. It is determined that the stop key is input in step 220 or the recording time set in step 222 has elapsed, and the CPU 110 proceeds to step 224 to stop OGM recording and then OGM recording mode in step 232. To enter standby mode. On the contrary, if it is determined in step 220 that the stop key is input or the time set in step 222 has not elapsed, the CPU 110 returns to step 214 to continue OGM recording.

Meanwhile, the voice signal input in step 216 is determined to be an invalid signal, and the CPU 110 controls the answering machine 142 in step 226 to stop OGM recording. The CPU 110 deletes the OGM stored in the voice memory 120 in step 228 and then proceeds to step 230 and outputs an error message to the display unit 126 indicating that the input voice signal is invalid. In step 232, the OGM switches from the OGM recording mode to the standby mode.

As described above, the present invention can increase the response of the consumer by storing only the voice signal of a certain level or more as OGM in order to exclude that the OGM transmitted when the OGM is recorded small in the answering machine. It works. In addition, the present invention outputs an error message informing the user when the voice signal input under the OGM recording mode is invalid in the answering machine, so that the user can record the OGM again.

Accordingly, the present invention can transmit the correct OGM to the other party under the auto answer mode by recording the voice signal input under the OGM recording mode in the OGM recording mode only by the OGM.
