According to an embodiment, in operation 622 , the pre-processing module 620 may decode the received original audio content. For example, when the received original audio content is in a compressed form, the preprocessing module 620 may decompress it through a decoder. For example, when the format of the original audio content is a standard compressed audio coding format such as MP3 and OGG, the preprocessing module 620 may convert it into a PCM audio format such as WAV using a corresponding decoder.

According to an embodiment, in operation 623 , the preprocessing module 620 may divide the original audio content into a plurality of sub audio content.

According to an embodiment, the preprocessing module 620 may divide the original audio content based on system characteristics of the electronic device. For example, resource capabilities capable of simultaneously operating the electronic device may be determined.

For example, the preprocessing module 620 may check the number of simultaneously playable audio contents, the number of submixes that can be created simultaneously, and/or the number of interpreters that can be simultaneously created. For example, if the electronic device can simultaneously operate on 200 audio tracks, the number of submixes that can be created simultaneously and/or the number of interpreters that can be created simultaneously may be 200. According to an embodiment, the preprocessing module 620 may determine the number of divisions of the original audio content based on resource performance that can be operated simultaneously.

For example, various methods including an average magnitude difference function (AMDF) may be used as a method of searching for a pitch. For example, the preprocessing module 620 may divide the original audio content by a pitch section while searching for pitches in both directions of the beginning and the end of the audio signal in order to reduce the time required for the division. For example, the preprocessing module 620 may detect a pitch from both the start and end portions of the audio signal, and divide the original audio content based on the detected pitch.

According to an embodiment, in operation 626 , the pre-processing module 620 may skip a silent section in each sub-audio content. For example, each sub audio content may include a section in which no sound is made. For example, the silent section may include a section in which there is no sound or meaningful sound. For example, the pre-processing module 620 deletes (skips) a silent section included in the sub-audio content and reproduces it in order to shorten the reproduction time of the sub-audio content and increase the efficiency of converting audio into text by deleting unnecessary conversion sections. can According to an embodiment, the pre-processing module 620 may re-store the sub-audio content in which the silent section is skipped in the form of an audio track in operation 624 .

According to an embodiment, in steps 627 and 628 , the preprocessing module 620 may convert the output of a plurality of sub audio contents preprocessed through a submix into an input. For example, the preprocessed sub audio content may be provided as a submix output in operation 627 , and the submix output may be provided as a submix input in operation 628 . For example, the submix output and submix input can share the same memory space. For example, when an audio track in operation 624 is written to a memory corresponding to the submix output, the corresponding content (audio track) may be transmitted to the submix input. For example, audio content provided as a submix output may be mapped one-to-one with audio content of a submix input.

According to an embodiment, the preprocessing module 620 may record the sub audio content provided as a submix input in operation 628 in operation 629 . For example, in operation 629 , the preprocessing module 620 may generate an audio record corresponding to each sub audio content. According to an embodiment, a memory space corresponding to an audio record may include a memory space corresponding to a submix input. For example, sub audio content provided as a submix input may be recorded as an audio record. According to an embodiment, the audio track of operation 624 and the audio record of operation 629 may be mapped one-to-one. For example, the audio track of operation 624 may be provided as a submix output of operation 627 and a submix input of operation 628 and provided as an audio record of operation 629 . For example, an audio track corresponding to each of the plurality of sub audio contents and an audio record corresponding to each of the plurality of sub audio contents may be mapped. For example, the pre-processing module 620 may generate an audio track and an audio record corresponding to each of the plurality of sub-audio contents, so that each of the plurality of sub-audio contents is transmitted to the interpreter module 630 without mutual interference. .

According to an embodiment, the order of operations 623 to 626 may be changed. For example, operation 626 of skipping the silent section may be performed before operation 623 of dividing the original audio content into a plurality of sub audio content.

According to an embodiment, the electronic device may convert the divided sub-audio contents 710 , 720 , 730 , 740 , and 750 into text while simultaneously playing them. For example, the electronic device converts the entire original audio content 700 into text by simultaneously and parallelly converting each of the divided sub audio content 710 , 720 , 730 , 740 , and 750 into text. It can reduce the time required. For example, if the total time of the original audio content 700 is 10 minutes and the original audio content 700 is divided into 5 sub-audio contents (710, 720, 730. 740, 750) with a length of 2 minutes, the original audio In the case of converting the entire content 700 into text while playing it, a playback time of 10 minutes is required. However, when the content 700 is divided into sub-audio contents 710, 720, 730, 740, and 750 and played at the same time, a playback time of 2 minutes Text conversion may be possible later.

Referring to FIG. 7B , the electronic device according to an embodiment may divide the original audio content 700 into a plurality of sub audio content 710 , 720 , 730 , 740 , and 750 in consideration of the characteristics of the audio signal. . For example, the electronic device sequentially recognizes pitches in the forward and/or reverse directions of an audio signal included in the original audio content 700 , and generates a plurality of original audio content 700 based on the recognized pitch. It can be divided into sub-audio contents.

According to an embodiment, in operation 760 , the electronic device may recognize the start part and the end part of the audio signal included in the original audio content 700 .

According to an embodiment, in operation 771 , the electronic device may initialize the forward division pointer S of the audio signal to an offset of the beginning of the audio signal.

According to an embodiment, in operation 773 , the electronic device may recognize the forward pitch section lenS from S of the audio signal. For example, the electronic device may recognize the first forward pitch from S of the audio signal and recognize the section from S to the first forward pitch. According to an embodiment, in operation 775 , the electronic device recognizes the forward pitch interval ( lenS) data can be stored in memory.

According to an embodiment, in operation 777 , the electronic device may update the forward division pointer by adding the forward pitch section lenS to the forward division pointer S. For example, the electronic device may update the updated forward dividing pointer S′=previous forward dividing pointer S+forward pitch interval lens. For example, the updated forward division pointer S′ may indicate a pitch point sequentially recognized from the beginning of the audio signal. According to an embodiment, the electronic device may divide a point corresponding to the updated forward dividing pointer S′ in the original audio content 700 (audio signal).

According to an embodiment, in operation 781 , the electronic device may initialize the backward division pointer E of the audio signal to an offset of the end of the audio signal.

According to an embodiment, in operation 783 , the electronic device may recognize the reverse pitch section lenE from E of the audio signal. For example, the electronic device may recognize a first reverse pitch from E of the audio signal and recognize a section from E to the first reverse pitch.

According to an embodiment, in operation 785 , the electronic device may store data of the reverse pitch period lenE in the memory.

According to an embodiment, in operation 787, the electronic device may update the backward division pointer by subtracting the forward pitch section lenS from the backward division pointer E. For example, the electronic device may update the updated backward partitioning pointer E′=previous backward partitioning pointer E-reverse pitch section lenE. For example, the updated backward segmentation pointer E' may indicate a pitch point sequentially recognized from the end of the audio signal. According to an embodiment, the electronic device may divide a point corresponding to the updated backward division pointer E' in the original audio content 700 (audio signal).

According to an embodiment, in operation 790 , the electronic device may determine whether the updated forward partitioning pointer S′ is equal to or greater than the updated backward partitioning pointer E′. According to an embodiment, when the updated S' is equal to or greater than the updated E', the electronic device may end the division of the original audio content 700 (eg, an audio signal included in the original audio content 700). For example, when S' is equal to or greater than E', it may mean that all pitches are recognized in the entire section of the audio signal. According to an embodiment, when the updated S' is less than the updated E', the electronic device may re-perform operations 771 and/or 781.

According to an embodiment, the electronic device may detect the pitch of the audio signal more quickly by detecting the pitch of the audio signal included in the original audio content from both directions of the audio signal. According to an embodiment, in operation 777 or 787, the electronic device divides the original audio content each time the forward division pointer or the backward division pointer is updated in operation 777 or after detecting all pitches of the audio signal, stored data (eg, the A point of the audio signal corresponding to the detected pitch may be divided based on the detected or updated forward pitch interval, reverse pitch interval, forward division pointer, and/or backward division pointer) while performing the operations of FIG. 7B .

According to an embodiment, the electronic device may simultaneously perform operations 771 to 777 and operations 781 to 787 in parallel with each other. According to an embodiment, the electronic device may omit one of operations 771 to 777 and operations 781 to 787 .

The operations illustrated in FIG. 7B are examples of a method for the electronic device to divide the original audio content 700, and according to various embodiments, the method for the electronic device to divide the original audio content 700 is not limited thereto.

8A to 8D are diagrams for explaining an operation in which an electronic device reproduces divided sub-audio contents, according to an exemplary embodiment.

According to an embodiment, the electronic device (eg, the electronic device 101 of FIG. 1 or the electronic device 300 of FIG. 3 ) may adjust the speed of the sub audio contents when playing a plurality of sub audio contents. According to an embodiment, the electronic device detects a pitch of the audio signal 810 included in each sub-audio content, and based on the detected pitch, overlaps at least some sections of the sub-audio content and reproduces it. For example, the electronic device may overlap and reproduce at least some sections of the sub audio content based on the detected pitch period.

Referring to FIG. 8A , the pitch of the audio signal 810 is a factor sensitively responding to human hearing, and may mean a minimum unit of the audio signal 810 that can be understood by humans. For example, the pitch of the audio signal 810 may form a local minimum in the audio signal 810 . For example, P1, P2, P3, and P4 may be pitches of the audio signal 810, and intervals between P1, P2, P3, and P4 may be pitch periods. According to an embodiment, the electronic device may detect the period of the pitch of the audio signal 810 included in the sub-audio content for each sub-audio content. According to various embodiments, as a method of detecting the period of the pitch, various methods including an average magnitude difference function (AMDF) method may be used.

8B to 8D , the electronic device may increase the reproduction speed of the sub audio content by overlapping at least a portion of the sub audio content.

For example, as shown in FIG. 8B , it is assumed that sub audio content has a pitch period of 8 samples and an audio signal composed of 2 pitches. For example, FIG. 8B shows the audio signal before superposition. For example, the audio signal before superposition is the first to sixteenth samples (x[1], x[2], x[3], x[4], x[5], x[6], x[7] ], x[8], x[9], x[10], x[11], x[12], x[13], x[14], x[15], x[16]) can

According to an embodiment, the electronic device may determine the number of overlapping samples in the audio signal based on the double speed. For example, the electronic device may determine the number of samples to be overlapped by using Equation 1 below.

For example, FIG. 8C shows a case where the double speed is doubled. For example, by Equation 1, the number of samples to be superimposed = pitch period - (pitch period / double speed) = 8 - (8/2) = 4.

For example, the electronic device may overlap and reproduce at least some sections of the audio signal based on the determined number of samples to be overlapped. For example, the electronic device may include a fifth to eighth sample (x[5], x[6], x[7], x[8]) and a ninth to twelfth sample (x[9], x [10], x[11], x[12]) can be nested. For example, after the overlapped result first to fourth samples (x[1], x[2], x[3], x[4]), the overlapped samples (x[5]', x[6] ]', x[7]', x[8]') followed by the thirteenth to sixteenth samples (x[13], x[14], x[15], x[16]) can lead For example, the electronic device may reproduce an audio signal in which some sections are overlapped. For example, when the electronic device reproduces an audio signal in which some sections are overlapped, 4 samples are reproduced from the signal of the second pitch period, and thus the audio signal is reproduced at twice the reproduction speed than when the existing 8 samples are reproduced. can play For example, when the audio signal is not overlapped in the second pitch period, the ninth to sixteenth samples (x[9], x[10], x[11], x[12], x[13], x[14], x[15], x[16]) are reproduced, but only the 13th to 16th samples (x[13], x[14], x[15], x[16] ]), so the playback speed can be doubled.

For example, FIG. 8D shows a case where the double speed is 4 times. For example, by Equation 1, the number of samples to be superimposed=pitch period-(pitch period/double speed)=8-(8/4)=6.

For example, the electronic device includes a third sample to eighth samples (x[3], x[4], x[5], x[6], x[7], x[8]) and a ninth sample to Fourteenth samples (x[9], x[10], x[11], x[12], x[13], x[14]) may be overlapped. For example, the superimposed result of the first sample (x[1]) and the second sample (x[2]) is followed by the superimposed sample (x[3]', x[4]', x[5]', x[6]', x[7]', x[8]') may be followed, followed by a fifteenth sample (x[15]) and a sixteenth sample (x[16]). For example, the electronic device may reproduce an audio signal in which some sections are overlapped. For example, when the electronic device reproduces an audio signal in which some sections are overlapped, two samples are reproduced from the signal of the second pitch period, and thus the audio signal is reproduced at a reproduction speed four times higher than in the case of reproducing the existing eight samples. can play For example, when the audio signal is not overlapped in the second pitch period, the ninth to sixteenth samples (x[9], x[10], x[11], x[12], x[13], x[14], x[15], x[16]), but after overlapping, only the 15th sample (x[15]) and the 16th sample (x[16]) need to be played, so the playback speed is increased can be quadrupled.

It can be stored in association with (941).

For example, the electronic device detects a tag related to at least one of the sub audio contents 910 , 920 , 930 , 940 and 950 (eg, the third sub audio content 930 and the fifth sub audio content 950 ). may not be created.

According to an embodiment, the electronic device may generate the integrated text 990 of the original audio content by integrating the text converted from each of the sub audio contents 910 , 920 , 930 , 940 and 950 .
