201040940 VI. Description of the Invention: [Technical Field] The present invention relates to a sound processing device, a chat system, a sound processing method, an information recording medium, and a program, which are very suitable for doing something by the user's voice. Continuous communication of degree and no uncomfortable conversation. [Prior Art] ❹ Don’t play online or SNS (social network service (s〇ciai

In the field of Network Service), a voice chat system is used. The voice chat system is used to detect the voice of the user by using a microphone, and the voice data (audio data) of the voice is transmitted to the terminal device of the other user. On the other hand, the voice data is processed in a two-way manner by the process of reproducing (playing) the speaker or the headset of the counterpart terminal device, thereby performing chat. This technique is disclosed in Patent Document 1 below. Here, in Patent Document 1, a technique is proposed in which an ambient sound around a user in a virtual (virtual Q) space and a sound emitted by the user are combined and transmitted to other users to improve the sound. The chat system is on the spot. [PRIOR ART DOCUMENT] Patent Document 1: Japanese Laid-Open Patent Publication No. 2006-343447 [Draft of the Invention] [Problems to be Solved by the Invention] 3 201040940 However, the waveform data of the sound emitted by the user has a very large amount of data. It is very large, so it is easy to cause problems such as transmission delay. In order to allow users to communicate properly, it is necessary to suppress the use of unspoken words and suppress the transmission of infringing privacy content. Ο Ο The present invention is to solve the above problems. The problem was developed to provide a sound processing device, a chat system, a sound processing method, an information recording medium, and a program, which are very suitable for a certain degree of communication by the user's voice, and will not do it. [Means for Solving the Problem] In order to achieve the above (4) 'in accordance with the principles of the present invention, the following invention is disclosed. The first aspect of the sound processing apparatus includes an input receiving # and a generating unit. And the output unit is configured as follows. Second, the input receiving unit receives the sound of the user. Ii ii Γ Γ Γ Γ Γ Γ Γ Γ Γ Γ Γ Γ Γ Γ Γ Γ Γ Γ Γ Γ Γ Γ Γ Γ Γ Γ Γ Γ Γ Γ Γ Γ Γ Γ Γ Γ Γ Γ Γ Γ Γ Γ Γ Γ Γ Γ Γ Γ Γ Γ Γ Γ Γ Parameters, typical and + + characteristic parameters of the car day. Make a large D with a basic frequency of eight, with the amplitude or volume of the waveform, the fundamental frequency, the size of the two-bovine component, or the characteristic parameters of the time-frequency component, the time is shy and change. It is extracted by a technique such as discrete high-speed 1 - Beixun, which is typically a fast Fourier transform. Moreover, the generating part is the root sound. Here, the generating unit, the data is generated to generate a synthetic sound system. The number of the characteristic data of the predetermined sound data is replaced by the value of the extracted characteristic parameter to generate a synthesized sound. As the predetermined sound data, the sound data composed of the sine wave and the dubbing prepared in advance can be used. Sound data such as the sound of a member or the sound of a musical instrument. The difference between the predetermined sound data and the synthesized sound generated is the value of the characteristic parameter. The characteristic parameter of the synthesized sound is replaced by the characteristic parameter of the predetermined sound data. The value of the characteristic parameter is obtained. Ο 〇 As described above, 'as a characteristic parameter, when amplitude or volume is used' is the vibration by changing the predetermined sound data. Amplitude or volume to generate a synthesized sound. Also as a characteristic parameter, when a fundamental frequency is used, a synthesized sound is generated by changing a key of a predetermined sound data. Moreover, as a characteristic parameter, when a basic frequency is employed The size of the component, or the size of the 疋, β, β main ϊ ά ά 手 手 手 手 手 手 手 手 手 手 手 手 手 手 手 手 手 手 手 手 手 手 手 手 手 手 手 手 手 手 手 手 手 手 手 手 手 手 手 手The time change of the size, intensity, height, and % of the sound is the same as that of the user. Therefore, the 'synthesis sound system is considered to reflect the user's feelings to some extent. In addition, since the synthesized sound becomes not "The voice of human beings", = even if the user utters a phrase or an article, the content of the phrase or article in the synthesized voice becomes unintelligible. Further, the output unit outputs the generated synthesized sound. : This is the synthetic sound that is turned out, as the above changes: but it becomes a state in which the film cannot be transmitted by sound = early. Therefore, even if the user speaks the statement of invasion of privacy or the content of the statement is not transmitted to the other party according to the 201040940, according to the present invention, although the detailed content of the user cannot be obtained as the language m, the user can Their feelings come to communicate meaning. In particular, it is possible to suppress disputes caused by the contents of the users' speeches.

Further, in the sound processing device of the present invention, the characteristic parameter can be constituted by the amplitude or volume of the waveform, the fundamental frequency, the magnitude of the fundamental frequency component, or the time variation of the magnitude of the representative frequency component. As described above, this configuration is a preferred embodiment of the present invention. Further, as a predetermined representative frequency component, a component size for each predetermined plurality of frequencies can be obtained, and a combination of a frequency and a component size can be obtained for a predetermined number of peaks of the frequency distribution. Further, in the sound processing device of the present invention, the extracting unit configuration can extract the characteristic parameter at a frequency less than 20 times.

Speakers of anti-public order and goodness 0 The human audible range is 20 Hz to 20 kHz, so in order to completely recover the waveform data of the sound, it is necessary to have a sampling frequency of 40 kHz or more. Since the sound of the telephone does not contain the sound quality of frequency components above 4000 Hz, the sampling frequency of the coffee (10) must be used when the sound quality of the telephone is to be maintained. On the other hand, if a sampling frequency of less than 2 Hz is used, the amount of data that is not processed by the time is reduced, and the language information of the phrase or article transmitted by the voice can be completely removed. 9 Right According to the present invention, not only can the data s which must be processed be greatly reduced, but also the meaning can be communicated by words to become effective in preventing invasion of privacy or violation of public "= 201040940, etc. In the sound processing device of the present invention, the extraction unit performs discrete Fourier transform on the received sound, and obtains a frequency distribution: a predetermined number of frequency components, and a characteristic parameter is added: a generation unit In the extraction unit, the waveform data corresponding to the extracted:: frequency component is amplified in advance to the size after extraction and δ is formed to generate a synthesized sound. Ο Ο : This is the y, in the extraction unit, A predetermined frequency component, ', or a large y, 'as a characteristic parameter' of a frequency component of a predetermined number of portions above the peak is generated as a characteristic parameter, and a composite sound is generated. The material is cut into a knife to remove the mask. When the waveform data corresponding to each frequency component is a square wave, the waveform data is read and replaced, but 疋, other extractions 1 may also be used according to the present invention. In the sound processing device of the invention, the "basic frequency of the waveform corresponding to the center = waveform data" and the component of the frequency component are respectively selected in advance. The I of the multiplication frequency of the fundamental frequency is the waveform data corresponding to each frequency component, and although the basic length is the same, the waveform number 掳 / - is used as the waveform data of the different sounds. For example, the item rate component is assigned to (predetermined for) piano sound, peak 7 201040940, the second frequency component is assigned to the guitar, the component system is assigned to the bass sound, etc. The frequency of the third digit of the peak: Ben According to the invention, it is possible to output various kinds of arpeggios that reflect the characteristics of the sound emitted by the user. In the case of the sound processing device of the invention, the generation unit is a candidate for the self-recovery data, and its characteristic parameters are obtained. The candidate sound data closest to the extracted parameter is selected, and the sound data is supplemented as the predetermined sound data. ... For example, four candidate sounds are obtained. The peak of the rate distribution, the order, that is, the ", the private + material gradually increase the sound data, etc.. The order of bass, guitar, piano, to allocate the strip according to the present invention, can output various sounds of the anti-warm The chat system that reflects the characteristic sound of the sound emitted by the user, which is another aspect of the invention, has a first sound 9 that receives the synthesized sound of the sound emitted by the first user and turns to the second::: Wheeling in and receiving the sound from the second user to the sonar processing device, the second user; and the sound wheel is placed, the sound processing unit is the processing unit generating unit and the output unit. The device includes an input receiving unit, an extracting unit, and an input receiving unit to receive a round of sounds emitted by the user. The extracting unit extracts characteristic parameters of the received sound. The generating unit generates an output unit based on the predetermined sound data, and outputs the generated synthesized sound. Sound day. 8 201040940 Further, the generating unit generates a synthesized sound by replacing the characteristic parameter of the predetermined sound data with the value of the extracted characteristic parameter. ^ The characteristic parameters of the first sound processing device and the second sound processing device are transmitted from the extracting unit to the generating unit through the computer communication network. The present invention applies the sound processing device to the voice chat, and uses the computer communication network. Connected between the extraction unit and the generation unit. ,,

Right according to the present invention, by providing a system similar to voice chat, it is impossible to obtain the detailed speech content of the user as the speech information = the feelings of the users to communicate the meaning. In particular, it is possible to suppress disputes caused by the contents of the speech by the users. According to another aspect of the present invention, the sound processing receiving unit, the extracting unit, the generating unit, and the output unit perform sound processing: a sound processing method for setting = an input receiving step, an extracting step, and an output step, which are configured as follows. In the second:::w input receiving unit receives the user's sending unit to extract the received sound, and collects the parameters in the extracting step. Further, in the generation step, wow occupies R& _ generates σ 摅戎 to generate a synthesized sound based on the number of sounds 既.

A schematic diagram showing a schematic configuration of a voice processing device and a voice system using the voice processing device according to the present embodiment. Hereinafter, an outline of each unit of the voice processing device will be described with reference to the same figure. The chat system 211 of the present embodiment is a system. The sound processing device 2〇1 includes an input receiving unit 202 and an extracting unit 203, respectively. The input unit 204 and the output unit 205. Here, the input receiving unit 2 0 2 receives the voice input from the user. In the present embodiment, under the control of the CPU 1〇1, the microphone m can function as an input receiving unit. In addition, the 'extraction unit 203 extracts the received sound characteristic parameters. In the present embodiment, the 'sound processing unit u〇 and cpui〇1 function as the extraction unit 203. 'The synthesized sound is generated based on the predetermined sound data. The synthesized sound generated here is the sound parameter of the predetermined sound data, which is replaced by the characteristic parameter extracted by the extracting unit 2〇3. . In the present embodiment, the function of the sound generating unit 2〇4 is performed. The processing unit (1) and the coffee maker 101' play the output unit 205. The output unit 205 outputs the output unit 205 under the control of the CPUUU and drives the speaker or the earphones only by the day-to-day processing unit 110. ° Moreover, as shown in the figure, the system 211 and the two sound processing devices 2 are located. Although it is realized by the user that the two devices 100 used by the user for 3 seconds are used for processing, the sound processing device 2 (the extraction unit 2G3 of the cymbal and the generating unit) The computer communication network t communication transmits the $. The fine input system is used as the input unit 2 for the part 203 and the part 205, that is, the information processing device 100 used by the user A is used to input the sound of the player A.生成2盥 extracts the generating unit 204 and the round-out function for the sound generated by the 纟B. ❹ Μ ' Μ (4) The information processing device (10) is used as an input receiving unit 2〇2 for the sound emitted by the user. The extracting unit 2〇3 and the generating unit 2〇4 and the output unit/swing function for the user's voice are emitted. Fig. 3 is a flow chart showing the control flow of the communication processing performed by the sound processing unit 2〇1. This corresponds to the processing performed by the input receiving unit 2〇2 and the extraction unit 203. Hereinafter, the description will be made with reference to the figure. When this process is started, the coffee waveform input function from the microphone (1) is used. RAM1〇3 is initialized (step s3〇. 20 1040940 Here, in the RAM 103, two buffers are prepared, and the inside of the buffer is prepared in advance. The buffer is only capable of recording sound waveform data input from the microphone "wind 111 for a predetermined length of time. From the microphone 111 The sampling frequency of the sound waveform data can be changed by the capability and setting of the sound processing unit 110, but can also be set to any of 44100 Hz, 22050 Hz, or 11 〇 25 ίί , and the accuracy of the A/D conversion is typically It is set to 8-bit or 16-bit mono (mono). * The predetermined length of time stored in the buffer is typically set to achieve the vertical processing of the information processing device 201 of the sound processing device 201. An integer multiple of the sync insertion period. For example, when the period of vertical sync insertion is i / 6 q seconds (equivalent to 60 Hz), the length of the buffer is typically 〗 / μ sec, I 〆 〇 或 or 1/20 Second α Here, 1/20 second (equivalent to 2〇Ηζ) is equivalent to the lower limit of the human audible frequency domain (range). That is, when the waveform data changes, it is equivalent to human beings - feeling "volume ( Vibration size) Or the boundary of any of the "changes in the timbre (waveform)", so in the present invention, this time length is typically employed. For example, in the case of mono sampling with a 16-bit number, the sampling frequency is 441. When the buffer length is (1 6/8 ) X ( 441 00/20 ) ^ 4 410 bytes, and 'the edge of the buffer from the microphone 111 is started to the buffer in the RAM 103. The buffer is accumulated (step S302), and in parallel with this, the following processing is also performed for the other side buffer in the RAM 103. 19 201040940 That is, the feature parameters are extracted from the waveform data column of the buffer (step S303). Here, the waveform data column to be memorized in the buffer is set to al5a2, ...'aL. In the above example, ai, a2, ..., are all integers having a bit number, L = 2205. As the simplest characteristic parameter, you can use:

(1) The average value of the absolute value of displacement Σ t = iL | 丨 / L (2) The square of the displacement Σ tMLat2 / L 〇 (3) the sum of the absolute values of the displacement ς ... LI at 丨 (4) the square of the displacement Σ t = iLat2 and so on. It is equivalent to the characteristic parameter of the sound size input from the microphone 1Π. More complex feature parameters are detailed later. It is said that the characteristic parameter of the shai is transmitted to the other party's resource processing device 1100 through the NIC 109 of the information processing device 1 (step S304) until the accumulation of the buffer has begun in step S3G2. Until the end of the '- straight standby (step S305). Moreover, in this standby, it is also possible to perform in parallel with other processes. Typically, the following reception processing will be implemented in parallel. The task of the buffer (steps to the end of the accumulation of the buffer, the exchange of two steps S306) 'back to step S3〇2. As described above, it is implemented in the waveform data unit of the buffer. Therefore, the characteristic parameter product (4) is 1/20 second. Therefore, compared with the normal voice chat, the transmission 1 system is implemented in 1/2° second, minus... Underneath, the amount of data that must be transferred is much reduced. Moreover, the buffer of the feature table r. (4) / Number of communications can also be implemented as appropriate 20 201040940 Figure 4 is a flowchart of the (four) process of the receiving processing performed by the non-sound processing device 2〇1, which corresponds to the generating unit 2〇4 and the output unit 2〇5 The treatment implemented. Hereinafter, it will be described with reference to this figure. The CPU 1 〇 1 ' first causes the output of the predetermined sound waveform data to start with the volume ( (step S401). As the predetermined sound waveform data, various sounds such as a sine wave, a square wave, a sound waveform of various instruments prepared by MIDI, and the like, and sound data of a voice actor can be used. q I will say, 'Control NIC 109, until the characteristic parameters from the other party's information processing device /100 arrive, and wait until the step (step). In this standby, it is also implemented in parallel with other processing. Typically, the above receiving processing will be implemented in parallel. When the s characteristic parameter arrives, the feature parameter is received (step S403). Then, the predetermined sound waveform data which has been started in step S401 is rotated, and changed to a volume 成 which is proportional to the received characteristic parameter (step S404), and then returns to step S402. By means of these communication processing and receiving processing, the sound of the volume can be changed in accordance with the size of the voice communicated by the communication side user, so that the receiving side user can hear it. The size of the sound θ reflects the feelings of the other party's users, so even this kind of processing can communicate to some extent. The sound heard by the user on the other receiving side is simply the sound of changing the sound of the predetermined voice data, so it is impossible to know what kind of phonology (sound) has been sent. Therefore, even if the communication side user makes a statement that violates the public order of 21 201040940, the user on the receiving side cannot know the content. Therefore, it is possible to prevent disputes caused by the contents of the speech. Furthermore, the relationship between sound size and emotion is irrelevant regardless of the language used. In the present embodiment, the sound of the sound on the receiving side is unclear, and since the original communication is based on incomprehensible speech, the user does not have the user on the communication side and the user on the receiving side. Words that can understand each other, because there is no language-induced obstacles, 'but' can promote meaning communication. In the above embodiment, although the sound size is extracted as a characteristic parameter to change the volume of the sound to be outputted, this aspect can be variously changed. First, as the extracted characteristic parameters, the method of (5) the basic frequency can be considered. In order to obtain the fundamental frequency, the waveform data sequence (1), a2', and aL accumulated in the buffer are subjected to discrete high-speed Fourier transform, and the frequency having the peak of the largest ❹ component can be obtained. Further, the basic frequency is combined with any of the above (n to (4), and transmitted as a characteristic parameter to the information processing apparatus 100 of the other party. On the reception side, in step S4〇4, in addition to changing the volume It also reproduces (plays) the interval (frequency or scale) of the predetermined waveform data, and changes it to the fundamental frequency of the characteristic parameter obtained by the reception. When the sound waveform of various instruments prepared by sine wave, square wave, MIDI, etc. is used 'As long as the reproduction frequency of the sound waveform data is changed according to the characteristic parameters obtained by the reception, it is equivalent to more detailed control of the "replacement scale" applied by Karaoke κ, etc. 2010 201040. When the voice data of the voice actor or the like is used, it is only necessary to change the scale of the waveform of the up-and-down waveform of the reproduction frequency specified in the characteristic parameter to be transmitted, and the sound level is changed. In addition, the voice can also be transmitted: the other party 'by swaying or tone, etc.' can understand the user's feelings in more detail, meaning communication is better. A degree Ο In addition, (4) (4) The high-speed Fourier transform of the high-speed Fourier transform, (4) The size of the frequency component of the complex frequency is used as the characteristic parameter. The method π-: on the receiving side is prepared in advance to correspond to a plurality of frequencies =:, The magnification of each waveform data is proportional to the ratio of the corresponding frequency component. Typically, the drums, bass, guitar, and piano are used in consideration of the sound source of any of the above (1) to (4). Here, the frequency of the representative voices of these instruments is used as the above-mentioned "established complex frequency". The second-party side is used to make the volume of each instrument, with the Fourier turn, for the representative frequency of the instrument. The big part of the extracted component: change. With this treatment, it is played like a jazz band. The sonar system rate == When using these, there are also (7) one or more frequency sheep. The frequency and the size of the peaks in the band are used as the feature. The band and the giga band are determined in advance by the frequency band for the drum, the frequency band for the TO port for the bass, and the frequency band of the bass. Knot 23 201040940 If you select a peak in each frequency band, and select a number of peaks for each frequency band. For example, the piano is compared with other instruments: " is: or a wider band' Select the frequency of the two peaks of the peak, and match it to the side, and the output of the waveform data of each instrument is high and the peak frequency is 'at the same time, with its peak:

And change. When a plurality of peaks are selected for an instrument, the plural sound can be played with the instrument. Ye, and Han Hancheng In this way, you can get the result of the sound of the jazz human voice. To play the analogy, the above methods can be combined or omitted as appropriate. In this way, according to the present embodiment, by providing a system similar to voice chat, although the user's detailed speech content cannot be obtained as a language: information can be communicated by the feelings of the users. , Yuba can suppress disputes caused by the content of the user's speeches. 0, and 'for this application', based on the Japanese Patent Application No. 2009 012753, the priority is claimed. The entire system is incorporated in the present application. [Industrial Applicability] As described above, according to the present invention, it is possible to provide a sound processing device, a chat system, a sound processing method, an information recording medium, and a program, which are very suitable for borrowing.
