1. Field of the Technology
The present technology relates to a command processing apparatus applicable to a game apparatus, for example. More specifically, the present invention relates to a command processing apparatus that executes a process according to an input voice command.
2. Description of the Prior Art
One example of such a kind of conventional apparatus is disclosed in a reference 1 (Patent Laying-open No. 11-319330) and a reference 2 (Patent Laying-open No. 2000-181676). According to the reference 1, when a voice is input to a microphone provided in a voice responsive toy, a voice pattern being coincident with the input voice pattern is specified out of a plurality of voice patterns stored in a memory. The voice responsive toy performs a movement in association with the specified voice pattern.
Furthermore, according to the reference 2, when an emitted voice by a player is taken by a microphone, a word corresponding to the emitted voice is detected by a voice recognition unit. A state of a character displayed on a screen changes on the basis of the detected word.
However, the reference 1 fails to disclose anything about a checking method of the voice pattern. Furthermore, since in the reference 2, it is necessary to detect a word corresponding to the emitted voice, this puts a heavy load on the voice recognition unit.
Therefore, it is a primary feature of the exemplary embodiment presented herein to provide a novel command processing apparatus.
Another feature of the exemplary embodiment is to provide a command processing apparatus capable of executing a process corresponding to an input voice command at a low load.
According to an exemplary embodiment, the command processing apparatus has a creating means, a storing means, an evaluating means, and an executing means. The creating means creates input waveform information including a plurality of amplitude values on a voice waveform input in real time. The storing means stores registered waveform information including a plurality of amplitude values on a voice waveform input in advance. The evaluating means acquires an evaluated value on the basis of the amplitude values of the input waveform information and the amplitude values of the registered waveform information. The executing means executes a process corresponding to a command assigned to the registered waveform information when the evaluated value acquired by the evaluating means satisfies a condition.
The input waveform information includes the plurality of amplitude values on the voice waveform input in real time, and the registered waveform information includes the plurality of amplitude values on the voice waveform input in advance. The input waveform information is created by the creating means (S63-S79), and the registered waveform information is stored by the storing means (98). The evaluating means (S87-S93) acquires the evaluated value on the basis of the amplitude values of the input waveform information and the amplitude values of the registered waveform information. When the evaluated value by the evaluating means satisfies the condition, a process corresponding to the command assigned to the registered waveform information is executed by the executing means (S107, S109, S13).
Since the difference of the amplitude values is evaluated, it is possible to execute a processing according to an input voice command at a low load.
According to an exemplary embodiment, amplitude values belonging to the respective input waveform information and the registered waveform information are represented by an absolute value. Thus, it is possible to decrease a load of the processing.
According to an exemplary embodiment, each of the input waveform information and the registered waveform information has L (L: two or more integer) amplitude values which are respectively detected at L positions. The evaluating means evaluates differences between M (M: integer less than L) amplitude values that are included in the input waveform information and respectively correspond to M detecting positions, and M amplitude values that are included in the registered waveform information and respectively correspond to M detecting positions. The changing means (S97) changes the noticed M detecting positions as to one of the input waveform information and the registered waveform information every time that an evaluating process of said evaluating means is completed. Thus, it is possible to easily obtain a proper evaluated value.
According to an exemplary embodiment, the changing means changes the noticed M detecting positions at N times (N: an integer less than “L-M”). The specifying means (S99) specifies an optimum evaluated value from among the N evaluated values acquired by the evaluating means. The executing means notices the optimum evaluated value. Thus, it is possible to increase the probability that the evaluated value satisfies the condition.
According to an exemplary embodiment, the evaluating means includes a first position specifying means, a second position specifying means, and a calculating means. The first position specifying means (S117) specifies a first detecting position which satisfies a first condition, the second position specifying means (S123) specifies a second detecting position which satisfies a second condition, and the calculating means (S131-S135) calculates the evaluated value on the basis of the number of the first detecting positions and the number of the second detecting positions. Here, the first condition is a condition that the difference is below a threshold value. The second condition is a condition that the difference at a detecting position anteriorly adjacent to the first detecting position is below the threshold value.
According to an exemplary embodiment, the evaluating means further includes a threshold value changing means. The threshold value changing means (S115) changes for each detecting position a numerical value indicated by the threshold value on the basis of the amplitude values of the registered waveform information. Thus, it is possible to precisely evaluate the difference.
According to an exemplary embodiment, the threshold value changing means increases the numerical value as the amplitude values are large.
According to an exemplary embodiment, the storing means stores the registered waveform information in correspondence to a plurality of commands. The evaluating means acquires the evaluated value with respect to each of the plurality of commands. Thus, it is possible to realize a variety of the processing.
According to other exemplary embodiments, it is possible to execute a processing according to an input voice command at a low load.
According to an exemplary embodiment, the command processing apparatus includes a creating means, a storing means, an evaluating means, an executing means, a changing means, and a specifying means. The creating means creates input waveform information including a plurality of amplitude values on a voice waveform input in real time. The storing means stores registered waveform information including a plurality of amplitude values on a voice waveform input in advance. The evaluating means acquires an evaluated value on the basis of the amplitude values of the input waveform information and the amplitude values of the registered waveform information. The executing means executes a process corresponding to a command assigned to the registered waveform information when the evaluated value acquired by the evaluating means satisfies a condition.
Each of the input waveform information and the registered waveform information has L (L: two or more integer) amplitude values which are respectively detected at L positions. The evaluating means evaluates differences between M (M: integer less than L) amplitude values that are included in the input waveform information and respectively correspond to M detecting positions, and M amplitude values that are included in the registered waveform information and respectively correspond to the M detecting positions.
The changing means changes the noticed M detecting positions as to one of the input waveform information and the registered waveform information every time that an evaluating process of the evaluating means is completed. The specifying means specifies an optimum evaluated value from among the N evaluated values acquired by the evaluating means. The executing means notices the optimum evaluated value. The storing means stores the registered waveform information in correspondence to a plurality of commands, and the evaluating means acquires the evaluated value with respect to each of the plurality of commands.

In response to an operation by depressing, stroking (touching), and so forth with a stick 24 such as stylus pen, or a finger (hereinafter, referred to as “stick 24, etc.”) on a top surface of the touch panel 22, the touch panel 22 detects a coordinates position of the stick 24, etc. to output coordinates position data.
It is noted that in this embodiment, a resolution of the display surface of the LCD 14 is 256 dots×192 dots (this is true for the LCD 12), and a detection accuracy of a detection surface of the touch panel 22 is also rendered 256 dots×192 dots in correspondence to the resolution of the display surface. However, the detection accuracy of the detection surface of the touch panel 22 may be lower than the resolution of the display surface, or higher than it.
In this embodiment, a game screen to be viewed by the player is displayed on the LCD 12, and a game screen to be viewed and operated by the player in association with the game screen of the LCD 12 is displayed on the LCD 14. Here, the game screen to be displayed on the LCD 14 includes an object, an icon, text information, etc. operable (touchable) by the stick, etc. The player directly touches the object displayed on the LCD 14 by the stick 24, etc. to thereby perform the object selection, the coordinates input, etc.
Also, it is possible to instruct other various inputs depending on the kind of the game. For example, it is possible to select texture information and a command icon displayed on the display screen of the LCD 14, and instruct a scrolling direction of the game screen (map) displayed on the LCD 12.

Furthermore, in this embodiment, the stick 24 can be inserted into a housing portion 26 provided in proximity to a right side surface of the upper housing 16a, for example, and taken out therefrom as necessary. It is noted that in a case of preparing no stick 24, it is not necessary to provide the housing portion 26.
Also, the game apparatus 10 includes a memory card (or game cartridge) 28. The memory card 28 is detachable, and inserted into a loading slot 30 provided on a rear surface or a lower edge (bottom surface) of the lower housing 16b. A connector 46 (see
A microphone 34 for fetching a sound is provided at the right side of the LCD 14, and a speaker 32 (see
Furthermore although omitted in
The connector 46 is detachably connected with the memory card 28 as described above. The memory card 28 includes a ROM 28a and a RAM 28b. Although illustration is omitted, the ROM 28a and the RAM 28b are connected with each other via a bus, and also connected with a connector (not shown) to be connected with the connector 46. Accordingly, the CPU core 42 gains access to the ROM 28a and the RAM 28b as described above.
The ROM 28a stores in advance a game program for a game to be executed by the game apparatus 10, image data such as a character image, a background image, an item image, a message image, etc., and sound data such as an effective sound, a BGM, an onomatopoeic sound of the character, etc. The backup RAM 28b saves proceeding data and result data of the game.
The RAM 48 is utilized as a buffer memory or a working memory. That is, the CPU core 42 loads the game program, the image data, the sound data, etc. stored in the ROM 28a of the memory card 28 into the RAM 48, and executes the loaded game program. The CPU core 42 stores in the RAM 48 temporary data such as game data, flag data, etc. in correspondence with progress of the game.
It is noted that such the game program, the image data, the sound data, etc. are loaded from the ROM 28a entirely at a time, or partially and sequentially so as to be stored into the RAM 48.
Each of the GPU 50 and the GPU 52 forms a part of a rendering means, is constructed by, for example, a single chip ASIC. The GPU 50 or the CPU 52 receives a graphics command (construction command) from the CPU core 42 to generate game image data according to the graphics command. Here, the CPU core 42 applies to each of the GPU 50 and the GPU 52 an image generating program (included in the game program) necessary for generating the game image data in addition to the graphics command.
It is noted that data (image data such as a polygon, a texture, etc.) necessary for executing the graphics command is stored in the RAM 48, and obtained by the GPU 50 or the CPU 52.
Furthermore, the GPU 50 is connected with a VRAM 56, and the GPU 52 is connected with a VRAM 58. The GPU 50 renders the created game image data in the VRAM 56, and the GPU 52 renders the created game image data in the VRAM 58.
The VRAM 56 and the VRAM 58 are connected to the LCD controller 60. The LCD controller 60 includes a register 62. The register 62 consists of one bit, for example, and stores a data value of “0” or “1” according to an instruction of the CPU core 42. The LCD controller 60 outputs the game image data rendered in the VRAM 56 to the LCD 12, and outputs the game image data rendered in the VRAM 58 to the LCD 14 in a case that the data value of the register 62 is “0”. Furthermore, the LCD controller 60 outputs the game image data rendered in the VRAM 56 to the LCD 14, and outputs the game image data rendered in the VRAM 58 to the LCD 12 in a case that the data value of the register 62 is “1”.
The I/F circuit 54 is connected with the operating switch 20, the touch panel 22, the speaker 32, and the microphone 34. Here, the operating switch 20 is the above-described switches 20a, 20b, 20c, 20d, 20e, 20L and 20R. When the operating switch 20 is operated, a corresponding operation signal (operation data) is input to the CPU core 42 via the I/F circuit 54. Furthermore, the coordinates data detected from the touch panel 22, the sound data fetched by the microphone 34 are also input to the CPU core 42 via the I/F circuit 54. In addition, the CPU core 42 reads the sound data necessary for the game such as a BGM, a sound effect, an onomatopoeic sound of the game character, etc. from the RAM 48, and outputs it from the speaker 32 via the I/F circuit 54.
It is noted that the program storing area 70, although illustration is omitted, stores other various programs required for progress of the game such as programs for reproducing/outputting a game image and a game sound.
The game play mode/registered envelope creating mode switching program 72 is a program for switching an operation mode between a game play mode and a registered envelope creating mode.
The registered envelope creating program 74 is a program for assigning an envelope (voice waveform information) created on the basis of a voice input by a player to a command required for operating a player character, and is executed in the registered envelope creating mode. When the player emits to the microphone 34 a word such as “jump”, “stop”, “right”, “left”, “pause”, and “end”, envelopes based on these voices are respectively assigned to a “jump” command, a “stop” command, a “right” command, a “left” command, a “pause” command, and a “end” command.
The voice input program 76 is a program for inputting the voice emitted by the player through the microphone 34, and a voice waveform data normalizing program 78 is a program for normalizing waveform data corresponding to the input voice.
The normalized data split program 80 is a program for splitting the normalized waveform data into 150 equal parts, and the maximum amplitude detecting program 82 is a program for detecting a maximum amplitude (absolute value) from each of partial waveform data.

Furthermore, the RAM 48 includes a data storing area 90. The data storing area 90 includes an operation data buffer 92, an input voice waveform storing buffer 94, an input envelope data buffer 96, and a registered envelope data buffer 98.

A description is made by use of
First, referring to
When the current operation mode is the game play mode, “YES” is determined in the step S5, and an initial setting of the game is performed in a step S7. In a step S9, it is determined whether or not a voice is input through the microphone 34. If “NO” here, the process directly proceeds to a step S13 to perform a game playing process. On the other hand, if “YES” in the step S9, a verification process is performed in a step S11, and then, the process proceeds to the step S13 to perform the game playing process.
It is determined whether or not the game is ended in a step S15. If “NO”, the process returns to the step S9 while if “YES”, the process is ended.
The registered envelope creating process in the step S3 is executed according to a flowchart in
A voice command including a voice section and non-voice section is input through the microphone 34 in a step S27, and the voice section is determined with regard to the input voice command in a step S29. If a length of the voice section is equal to or less than a threshold value TH1, or is equal to or more than a threshold value TH2, an error message is output in a step S31, and the process returns to the step S27. In contrast thereto, if the length of the voice section is above the threshold value TH1 and below the threshold value TH2, the process proceeds to a step S33 to eliminate a non-voice component from a head and an end of the waveform data representing the input voice command. In a step S35, the waveform data from which the non-voice component is eliminated is normalized, and in a succeeding step S37, the normalized waveform data is split into equal 150 parts.
When the voice command issued by the player is “jump”, waveform data shown in
In a step S39, “1” is set in a variable N. In a step S41, an absolute value W (N) max which is an absolute value of the maximum amplitude as to a partial waveform W (N) is detected (see
In a step S45, it is determined whether or not the variable N reaches “150”. If “NO” here, the variable N is incremented in a step S47, and then, the process returns to the step S41. Thus, the absolute values W (1) max-W (150) max are respectively detected from the partial waveforms W (1)-W (150), and the detected absolute values W (1) max-W (150) max are respectively set as the envelope values EK (1)-EK (150).
As to the partial waveforms W (1)-W (150) shown in
If “YES” is determined in the step S45, the process proceeds to a step S49 to store the envelope values EK (1)-EK (150) as a registered envelope K in the registered envelope buffer 98 shown in
It is determined whether or not the variable K reaches “6” in a step S51, and if “NO”, the process returns to the step S25. As a result, the process similar to the above description is performed on all the menu items displayed on the menu screen shown in
Meanwhile, in comparison to the registered envelope of “jump” shown in
The verification process in the step S11 shown in
If “YES” is determined in the step S61, a process similar to the above-described step S33-S47 is executed in steps S63-S77. Accordingly, the waveform data representing a voice command input during the progress of the game is split into 150 partial waveforms W (1)-W (N), and the absolute values W (1) max-W (150) max respectively detected from the split partial waveforms W(1)-W (150) are set as the envelope values E (1)-E (150). In a step S79, the envelope values E (1)-E (150) thus obtained is stored as an input envelope in the input envelope buffer 96 shown in
In a step S81, “1” is set in the variable K, and in a step S83, “−4” is set in a variable S, and in a step S85, “5” is set in the variable N. In a step S87, a difference between an envelope value EK (N) forming a registered envelope K and an envelope value E (N+S) forming the input envelope is evaluated.
It is determined whether or not the variable N reaches “146” in a step S89, and if NO, the variable N is incremented in a step S91, and then, the process returns to the step S87. Consequently, the partial evaluation process in the step S87 is repeated at 142 times, and a total of 142 partial evaluated values are obtained.
In a step S93, such the 142 of the partial evaluated values are totally evaluated, and in a step S95, it is determined whether or not the variable S reaches “4”. If the variable S is less than “4”, the variable S is incremented in the step S93, and the process returns to the step S81. Consequently, a series of processing in the steps S85-S93 is repeated at nine times, and nine total evaluated values are obtained. In a step S99, a total evaluated value being a maximum numerical value is specified from among the obtained nine total evaluated values.
It is noted that the reason why a numerical value applicable to the variable N is restricted to the “5”-“146” range in the partial evaluation process is that the variable S is changed in the “−4”-“4” range is considered. The range applicable to the variable N is restricted such that a correspondence between the registered envelope and the input envelope is sure to be secured in the partial evaluation process.
In a case that the input envelope of “jump” shown in
It is determined whether or not the variable K reaches “6” in a step S101, and if “NO”, the variable K is incremented in a step S103, and then, the process returns to the step S83. Accordingly, the process in the steps S83-S99 is repeated at six times, and the input envelope is compared with each of the registered envelopes 1-6. Consequently, six total evaluated values respectively relating to the registered envelopes 1-6 are obtained.
In a step S105, a total evaluated value having a maximum numerical value is detected from among the six total evaluated values thus obtained. In a step S107, it is determined whether or not the detected total evaluated value is above a defined value. If “YES” here, the process proceeds to a step S109 to validate a command assigned to a registered envelope corresponding to the detected total evaluated value. The game playing process in the step S13 shown in
For example, when the total evaluated value corresponding to the registered envelope 3 is detected in the step S105, the “right” command assigned to the registered envelope 3 is validated. The player character moves to the right as shown in
The partial evaluation process shown in the step S87 in
In a step S117, a difference absolute value |EK (N)−E (N+S)| which is a difference absolute value between the envelope values EK (N) and E (N+S) is compared to the threshold value TH (N). Here, if the difference absolute value |EK (N−E (N+S)| is equal to or more than the threshold value TH (N), the process is directly restored to the hierarchical upper level of the routine. On the other hand, if the difference absolute value |EK (N)−E (N+S)| is less than the threshold value TH (N), the variable X1 is incremented in a step S119, and it is determined whether or not the variable N is above “1” in a step S121.
If “NO” in the step S121, the process is directly restored to the hierarchical upper level of the routine. If “YES” in the step S121, the process proceeds to a step S123 to compare a difference absolute value |EK (N−1)−E (N+S−1)| which is a difference absolute value between the envelope values EK (N−1) and E (N+S−1) to the threshold value TH (N−1). Then, if the difference absolute value |EK (N−1)−E (N+S−1)| is equal to or more than the threshold value TH (N−1), the process is restored to the hierarchical upper level of the routine. On the other hand, if the difference absolute value |EK (N−1)−E (N+S−1)| is less than the threshold value TH (N−1), the variable X2 is incremented in a step S125, and then, the process is restored to the hierarchical upper level of the routine.
By repeating such the process at 142 times, the variable X1 indicates the number of the partial waveforms having approximately the same envelope value between the registered envelope and the input envelope, and the variable X2 indicates the number of partial waveforms approximately the same envelope value as to the adjacent partial waveforms.
The total evaluation process in the step S93 shown in
As can be understood from the above-description, the input envelope (input waveform information) includes a plurality of envelope values (amplitude values) detected from a voice waveform input in a real time manner, and the registered envelope (registered waveform information) includes a plurality of envelope values detected from a voice waveform input in advance. The input envelope is created in the steps S63-S79, and stored in the input envelope buffer 96 of the RAM 48. The registered envelope is stored in the registered envelope buffer 98 of the RAM 48. The difference of the envelope value between the input envelope and the registered envelope is evaluated in the steps S87-S93. If the evaluated value satisfies the condition, a process according to the command assigned to the registered envelope is executed in the step S13. Thus, the difference of the envelope values is evaluated, and therefore, it is possible to execute a process corresponding to the input voice command at a small load.
Furthermore, only the voice having a voice section whose length is equal to or larger than the threshold value TH 1 and is equal to or less than the threshold value TH2 is validated (S61), and therefore, the determination result is less influenced by a length of the voice. In addition, the waveform information does not include information relating to the frequency, and therefore, the determination result is less influenced by a tone. Consequently, accuracy of the determination is improved.
It is noted that the present embodiment is for performing the above-described simple process considering the fact that there is no need to completely analyze the voice in a game such as an action game that is restricted in command, that is, the game restricted in command does not need a process at a large load such as specifying a word indicated by the input voices by analyzing distribution of the frequency.
It is noted that although the LCDs 12 and 14 are vertically arranged in the above-described embodiment, the arrangement of the two LCDs may be changed as necessary. That is, the LCDs 12 and 14 may horizontally be arranged.
Furthermore, although two LCDs each displaying a screen are provided in the above-described embodiment, the number of the LCDs as a display portion may be changed as necessary. That is, it is appropriate that one LCD in the longitudinal shape is provided, and by vertically dividing the area, the touch panel 22 is provided on one side of the area. Thus, it is possible to display two images on the respective areas. Or, it is appropriate that one LCD in the transverse shape is provided, and by horizontally dividing the area, the touch panel 22 is provided on one side of the area. Thus, it is possible to display two images on the respective areas.
Although the exemplary embodiment presented herein has been described and illustrated in detail, it is clearly understood that the same is by way of illustration and example only and is not to be taken by way of limitation, the spirit and scope being limited only by the terms of the appended claims.
