KR930006538A - Voice signal generation wave sampling device of PC and its method - Google Patents

Abstract

The present invention relates to a voice signal generation and sampling device of a PC used for an educational PC or various voice service devices, and a method thereof. The voice signal of the PC was sampled using the address decoder.

The sampled voice data is used to generate a voice signal of the PC using a PC, a peripheral device driver, a switching unit, an integrator, and a seeker.

In addition, the present invention has developed a voice signal sampling method and a voice signal generating method of a PC using the voice signal sampling device of the PC and an algorithm suitable for the voice signal generating device.

The voice sampling data 3 is connected to the driving unit 20 through the input / output first port PT ₁ of the PC 10, and according to the output of the driving unit 20, the first switch 1 and the second switch ( 2) the switching unit 30 and the first switch 1 is directly connected to the speaker 50, the second switch 2 is connected to the speaker 50 through the integrator 40 Voice signal generator of a personal computer, characterized in that configured to generate a voice signal of the PC. Sound generation operation is started 101 when after the sampling data file open 102, the first parameter (S ₁₎ and to read, as step 103, the signal of the data file, the S _1, the second parameter data ( S ₂ ) and store 104, and store a value of “0” in the first port PT ₁ of the PC 10 (105), and transfer the next data from the opened data file to the S ₁ . in accordance with the reading (106) comparing the S ₁ and S ₂ (107) and the S comparing step ₁ and S ₂ (107) to the first port (PT ₁₎ of the PC (10) "0" step of transmitting the value of the value or "1" 109, 108, the S ₁ value if transferred to S ₂ store 110 and determines the kkeutnatneunga 111, files have not over the step (106 ) And continue processing, and if it is finished, closing (112) and returning (113) the sampling data file is sequentially performed to generate a voice signal of the PC. PC audio signal generation method. The first amplifier 65 and the second amplifier 67 for amplifying the voice signal input to the microphone 60 and the comparator 69 for comparing the first amplifier signal 6 and the second amplifier signal 7. A buffer 70 for receiving a low signal ("0") or a high signal ("1") from the LSB (D ₀ ) according to the output of the comparator 69; And an input / output address decoder (75) for enabling the data to be read to the PC (10) by enabling (PT ₂ ) to sample the voice signal of the PC. When the voice signal sampling operation is started 201, a data file 202 is generated and the sampling data is read into the first parameter S ₂ through the second port PT ₂ of the PC 10 (203). After clearing the second parameter S ₂ (204) and writing (205) to the memory device of the PC 10, the next sampling data is transferred through the second port PT ₂ of the PC 10 S _1. and read, as step 206, the S ₁ = 0 if the check 207 by subtracting 1 from this S ₂ in accordance with (S ₂ -1) or plus (S ₂ +1) hanhu saved back to S ₂ 208 and 209, and then rewrite 210 the S ₂ value to the memory device of the PC 10 and check if the operation is finished (211). If the jump continues and ends, closing (212) the generated file and then returning (213) are sequentially operated to sample the voice signal of the PC. Fling method. ※ Note: The disclosure is based on the initial application.
