The present invention relates to a method of processing a voice message, and more particularly, to a method of editing a voice message recorded using a voice processing device and a computer.

In general, a voice message processing system such as a voice answering device or a voice mail device is used for a subscriber to record a voice message such as an announcement message or an advertisement message by using a telephone to call the voice message processing system or to establish an analog transmission line. It has been recording by sending a voice message to be recorded by using.

On the other hand, the voice quality of the voice message used in the voice message processing system is more important than the function or reliability of the system, and general users hear the voice message of the system and judge the quality of the system.

Therefore, in the conventional voice message processing system as described above, the voice quality is remarkably degraded due to various noises on the transmission path as the voice message is recorded using the telephone. There was a problem that the band, in particular high frequency band can not have all good characteristics.

In addition, it was inconvenient to be able to record only if there is a voice message processing system.

Accordingly, there is a patent application No. 92-9191 filed by the same applicant as the present application as a technique for solving the above problems. The patent application No. 92-9191 records and plays back voice messages without degrading sound quality using a computer without using a separate voice message processing system.

However, in the above-described conventional voice message processing system and the patent application No. 92-9191, when the recorded voice is abnormal, that is, when the size of the voice is large or small or when the silent portion is long, There was a problem that you need to record again. In addition, there was a problem that whether or not conformity to the recorded voice is incorrect by the operator listening to judge the recorded voice.

Accordingly, an object of the present invention is to provide a voice message editing method using a computer capable of making a voice message suitable for a voice message processing system by editing only a necessary part while watching and listening to a voice message recorded using a computer equipped with a voice processing device. have.

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

1 is a block diagram of a system for carrying out the present invention, in which external voice input / output devices such as a telephone 10, an audio device 12, a microphone 14, a speaker 16, and a headphone 18 are connected. The audio processing device 56 is connected to the computer main body 58 through the system bus 103 of the computer, and the monitor 52 and the keyboard 54 are connected to the computer main body 58. In addition, the voice message processing system 60 may be connected to the computer main body 58.

The computer main body 58 includes a disk driver 42, a ROM 44, a RAM 46, a controller 48, an input / output interface 50, and a disk driver 42 connected to each other via a system bus 103. It is a common computer that consists of.

The voice processing device 56 includes an analog interface unit 20, a codec 22, a data converter 24, an ADPCM (Adaptive Differential Pulse Code Modulation) unit 26, and a DTMF (Dual Tone Multi-Frequency) receiver. And the reset signal generator 30, the controller 32, the ROM 34, the RAM 36, the common memory 38, and the address area selector 40. The voice processing device 56 may be incorporated in the computer main body 58.

The configuration and operation of FIG. 1 are described in detail in the aforementioned patent application No. 92-9191, and thus will be omitted.

2 is a flowchart of a voice message editing function according to the present invention, and the flowchart of FIG. 2 is a flowchart of the operation of the controller 48 of FIG.

3 is a memory map configuration diagram for carrying out the present invention.

When the operator inputs the edit key of the keyboard 54 while the file of the recorded PCM or ADPCM audio data is stored on the disk of the disk driver 42 of FIG. 1, the controller 48 displays (201) in FIG. In step (202) to step (203), the disk driver 42 reads the voice data of the file designated by the operator from the disk, stores it in the RAM 46, and monitors the waveform of the read voice data. It is displayed on the screen of 52.

In the above state, when the operator inputs a selection key for viewing and partially selecting the waveform displayed on the screen, the controller 48 performs only the voice data of the waveform according to the selection key input in steps 204 and 205. Leave the rest and delete the rest. Next, when the operator inputs a playback key for reproducing and listening to the audio data of the selected waveform, the control unit 48 stores the transmission command storage buffer as shown in FIG. 3 of the common memory 38 in steps 206 to 207. Transmits a playback start command to the voice processing device 56 by using the controller. In step 209, the voice data of the selected polarization waveform is transferred to the voice processing device 56 through the first and second PCM data storage buffers and the first and second ADPCM data storage buffers as shown in FIG. 3 of the common memory 38. send. Then, the control unit 32 of the voice processing device 56 controls the analog interface unit 20 to switch to the set output device, and then the codec 22, the data converter 24, and the ADPCM unit 26 are controlled. The control unit processes the audio signal of the voice message input from the computer main body 58 to output to the set output device. The controller 32 reads the voice data of the common memory 38, writes the voice data to the ADPCM unit 26 at a rate of 1 byte / 250 Hz when the voice data is ADPCM data, and in the case of PCM data, the data is read. The converter 24 writes at a rate of 1 byte / 125 Hz.

Accordingly, when the voice data is ADPCM data, it is converted into PCM data by the ADPCM unit 26, and then converted into serial data by the data converter 24, and then applied to the codec 22 to convert the voice data into an analog signal. Is converted. If the voice data is PCM data, it is immediately converted into serial data by the data converter 24 and then applied to the codec 22 to be converted into an analog voice signal. The audio signal of the analog is output to the set output device via the analog interface unit 20.

In the above state, the controller 48 proceeds to step 203 and repeats the above-described process. Accordingly, the voice data is optimally adjusted.

When the operator inputs a recording key as the output voice is optimally adjusted, the controller 48 stores the edited voice data on the disc through the disc driver 42 in steps 211 and 212. .

Therefore, the operator looks at the waveform displayed on the screen of the monitor 52, selects the waveform partly, plays back only the part, and adjusts the part of the selected waveform to make the optimum voice.

On the other hand, the display of the waveform of the voice data on the screen as described above in detail as follows.

First, if PCM or ADPCM data read from the disk is used, assuming that the width is 640 pixels on the graphic screen, PCM data is 125㎲ because Byte 125㎲ = 1 byte audio data. The voice of 80㎳ is displayed and ADPCM data is 250㎲ of 1 byte, so the voice of 640 125㎲ = 160㎳ is displayed. Sampling this at a reasonable rate allows you to display more data.

Secondly, in the case of using the sound counter, the sound data is judged to be sounded or silent in 128 byte units. That is, the number of noises in 128 bytes is set as the level. Therefore, the data is between 0 and 128, where 0 is no input and 128 are all valid. If this is displayed on the 640 pixel as described above, it is 128 250 ms 640 = 20480 ms, which is about 20 seconds of data. If you sample properly with this data, you will be able to display and edit voices with moisture lengths.

As described above, the present invention has an advantage of making a voice message suitable for a voice message processing system by editing only a necessary part while watching and listening to a recorded voice message using a computer equipped with a voice processing apparatus.
