[Effect of the Invention] According to the present invention, it is an object of the present invention to identify a character by distinguishing the extracted sound category from the game device. [Embodiment] Hereinafter, the present invention will be described in detail with reference to the accompanying drawings. [First Embodiment] Fig. 1 is a view showing an example of the appearance of a portable game device according to the present embodiment. As shown in the figure, the portable game device 1 (9) includes a microphone 1〇1, a display unit 102, an infrared light-receiving unit 1〇3, a wheel 1〇4', and a (4) bu 106 » The case where the portable game device is a device having the appearance configuration of the figure will be described. However, the arrangement of the display unit 1〇2, the button group 104106, or the shape thereof and the like are not limited to those shown in the figure, and various deformations may be considered. example. Further, the following description will be applied to the respective modifications by the following description. Further, in the drawings of Fig. 1 and the following, the description will be made centering on the portion used in the following description, and for example, a portion of the power switch or the like which is not directly related to the spirit of the embodiment will be omitted. Fig. 2 is a block diagram showing an example of a hardware configuration of the portable game device ι of the embodiment. The CPU (Central Processing Unit '2〇1) uses programs or data stored in ROM (read-〇nly memory) 2〇3 and temporarily stores it in RAM (Rand〇m). The information in the Aeeess Memc^y, random access memory 202, etc., controls the portable game device ι as a whole, and performs the following game processing. The RAM 202 can appropriately provide an area for data in the temporary memory processing. The ROM 203 stores programs or materials useful for causing the CPU 201 to perform overall control of the portable game device 100 or to perform game processing described below. The following table of roles 500 is included in this document. And 155212.doc 201204443 Also, the information in this table is properly loaded in RAM 202 for processing. The display unit 204 is configured to correspond to the display unit 1 〇 2 of Fig. 1, and performs character display or the like. The operation unit 205 is configured to correspond to the button groups 1〇4 to 1〇6, and accepts an operation from the user. The microphone 206 is a voice extracting mechanism for extracting a voice output from a specific device capable of voice output such as a television or a voice extracting mechanism for extracting ambient sound of the portable game device 100. The microphone 206 includes an amplifier for amplifying the extracted speech signal and a filter for canceling the noise. The infrared light receiving unit 207 is configured to correspond to the infrared light receiving unit 103, and is configured to perform infrared communication with other portable game devices 100 and the like. Next, the game processing performed by the portable game device 100 corresponding to the present embodiment will be described. Fig. 3 is a flow chart showing an example of game processing corresponding to the present embodiment. The program or data for causing the CPU 2〇1 to execute the processing according to the flowchart shown in FIG. 3 is stored in R〇M 2〇3 and executed by the CPU 2〇1 using the program or data. The portable game device 100 of the embodiment executes each process described below. First, in step S3 (H determines whether or not to start the game. If the game starts (YES in step S301), the process proceeds to step S3〇2. If the game starts, step S302 determines whether the portable game device is 〇〇 An instruction to start the extraction of the voice around the device is received. The instruction to start the extraction may be accepted based on, for example, a scroll wheel of the game body 100 (or a central switch). Alternatively, the microphone portion may be slidably configured, and: When the slide switch is set, when the slide switch is operated, it is regarded as receiving an instruction by the 155212.doc 201204443. If the extraction start command is accepted (YES in S302), the microphone 206 is used to start the voice in S303. When the extraction is started, the extraction of the extracted speech data is started in S3 04. S305 determines whether or not the analysis is completed. If the analysis is completed (YES in S305), the process proceeds to S306, and based on The result of the analysis is performed, and the character selection is performed. Then, in S307, the selected character is displayed on the display unit 102. Next, referring to Fig. 4, the voice data in S304 is referred to. The analysis method and the character selection method in S307 are explained. In FIG. 4, not only the microphone 206 can be implemented by hardware, but also the blocks 401 to 407 can be executed by the CPU 201 in the program stored in the ROM 203. Further, even if it is not the CPU 201, a dedicated logic circuit can be used. First, the analog voice signal obtained by the microphone 206 is amplified by the amplifier in the microphone 206, and after the noise is removed by the filter, it is input to the A. /D (analog/digit, digital/analog) conversion unit 401. The A/D conversion unit 401 converts the input analog signal into a 12-bit (or 10-bit) digital speech data having a sampling frequency of 44 kHz. Next, the digital voice data is in the sub-sampling unit 402, and the number of bits is reduced by sub-sampling, and then input to the digital filter 403. The digital filter 403 is a filter for extracting signals of a specific frequency. In the present embodiment, eight frequencies are used. Specifically, the frequencies correspond to the scales C6, C#6, D6, D#6, E6, F6, F#6, and G6, and the system is 1, 〇46.5 Hz, 1,108.7 Hz, 1,174·7 Hz, 1,2 44.5 Hz, 1,318.5 Hz, 1,396.9 Hz, 1,480.0 Hz, 1,568.0 Hz. s 155212.doc 201204443 The 8-pass filter processing result from the digital filter is input to the level determination quantization unit 404 to match the specific comparison pattern. The ratio pattern is a pattern in which the result of the digital chopper processing at the time of the predetermined input is not obtained, and the comparison graph - the comparison pattern is prepared for the above eight scales, and the mR can be stored by tabulation. 〇m 2〇3. If any of the output signals is used, and any of the comparison patterns for the eight scales is used, the signal is determined as the speech signal of the corresponding scale. If the voice signal of any scale is used, the value indicating the corresponding scale is input to the st/END sync detecting unit 4〇5. On the other hand, an error determination is made with all the patterns, and the error value is input to the start/end synchronization detecting portion 405. Further, in the silent section, since the output result from the filter does not have a fixed level', the value indicating the silent section is output. The a START/END synchronization detecting unit 4G5 stores the value from the level determination quantization P and determines whether or not a value indicating any scale is continuously input. Further, the judgment: indicates whether or not the value indicating the innocent interval is output after the value of the scale input continuously. In the present embodiment, (four) indicating the value of the scale is present in the area sandwiched by the silent section, and the data set as the data set and the detected data set is output to the code data output unit 4〇6. Further, if the above data set _ is not detected, the value (the environmental sound value) indicating the detection of the scale is output to the code data output unit 406 when the value indicating the 曰P is detected. The code shelling portion 4〇6 is generated from the combination of the values of the scales included in the data set obtained by the start/end synchronization detecting unit 405, and generates the code 155212.doc 201204443 data 'and outputs the data of the scale combination , " data indicates that '歹j, can be expressed as a 9-bit signal. In addition, the cakes, +, and the bodies are in the above-mentioned θ-order C6, C#6' D6, D#6, E6, F6 F#6, and G6, which are 8 to 7 A digital number that can be represented by 3 bits. The right order is set to 0 to 7, then (C6, C#6, D6) can be expressed as (2, 2). When the code data is generated, it can be seen that the analysis of the material is completed. Further, the code data can be generated only when a combination of three scales is detected by a continuous number: (for example, three times). When the player turns into the ambient sound value instead of entering the data set, the code capital

At this point, the character can be determined immediately by 'code data'. 155212.doc 201204443 Furthermore, when the code data represents an environmental sound value, any character can be randomly selected from a role registered in the table with a constant probability. According to the above embodiment, the speech outputted from a specific device such as a television set in a specific pattern as shown in Fig. 6 can be extracted, and the character corresponding to the scale included in the speech can be acquired. On the other hand, even when the ambient sound of the device 1 is extracted, the character can be randomly acquired with a constant probability. Fig. 6 is a view showing an example of a structure of a voice reproduced in a specific device such as a television. The voice data 6 shown in Fig. 6 is equivalent to the data of i times, and is repeated three times when reproduced by the television. The voice data is identified by a 0.5 second silent period (601, 6〇2) at the forefront and the last end. Furthermore, the voice data does not have to be set to the silent period (6〇1, 602) at the forefront and the last end, and when the silent period (601) is not set at the foremost end, if the last end of the silent interval (6〇2) is sandwiched When a detection interval of a specific digital scale signal and a detection area of a specific digital scale signal exist in the voice data, the data set can also be identified. The speech recognition interval is 6〇2 to 6〇4 minutes^ and contains 0.5 seconds of scale data. The voice data interval 6〇5 may also include any voice data, and the pitch of the start sound is preferably different from the scale of the scale recognition interval 6〇2. This is to prevent misjudgment of data sets. The voice data interval can be, for example, 〇8 seconds. Further, in Fig. 6, the time of each section is described only as an example, and therefore it may be longer than this time or shorter than this time. The user can recognize the voice as the voice due to the presence of the voice data interval (because of the insertion of the voice of the character, etc.). If a voice material 600 similar to that of FIG. 6 is used, and a comparison pattern corresponding to the scale type used for the scale recognition 155212.doc •10-201204443 is prepared, the voice data reproduced in a specific device such as a television can be used. The user gets a specific role. On the other hand, when an environmental sound that is inconsistent with the pattern of Fig. 6 is extracted, the user can acquire a character based on a constant probability. [Other Embodiments] The above processing (for example, the processing following the flowchart shown in FIG. 3 in the above embodiment) can be stored as a computer program in a memory medium such as cd_r, r〇m*dvD-ROM, or MO. The phantom computer reads (installs or copies) the memory media t memory program, and causes the computer to function as the game I corresponding to the present invention. Accordingly, it will be understood that such a computer program, and a memory medium in which the computer program has been recalled, are also within the scope of the present invention.
