(Embodiment 1)
<Configuration of game device>
FIG. 1 is a block diagram showing the configuration of the game device 5 of this embodiment. The game device 5 executes a predetermined game based on user's operation. A display 61 , a speaker 62 (playback device) and a controller 63 are externally connected or built into the game device 5 . The game progresses on the game device 5 based on the installed game program and game data.

The game device 5 has a network interface 51 , a graphics processing section 52 , an audio processing section 53 , an operation section 54 , a storage section 55 and a control section 56 . Network interface 51 , graphics processing unit 52 , audio processing unit 53 , operation unit 54 and storage unit 55 are electrically connected to control unit 56 via bus 59 .

The network interface 51 is communicably connected to the communication network in order to transmit and receive various data to and from, for example, the game device 5 and an external server device (not shown).

The graphics processing unit 52 draws game images including user characters and various objects related to the game space in a moving image format according to the game image information output from the control unit 56 . The graphics processing unit 52 is connected to the display 61, and the game image drawn in the moving image format is displayed on the display 61 as a game screen.

The audio processing unit 53 reproduces and synthesizes digital game sounds according to instructions from the control unit 56 . The audio processing unit 53 is connected to the speaker 62 , and the reproduced and synthesized game sound is output from the speaker 62 .

As described above, the speaker 62 is externally connected to or built into the game device 5 . As the speaker 62 externally connected to the game device 5, for example, a speaker configured by a plurality of speaker units such as those used in a home theater (hereinafter also referred to as a "home theater speaker"), or a speaker built into a TV. (hereinafter also referred to as "TV speaker"). Generally speaking, the performance of the speakers built into the game device 5 (hereinafter also referred to as "built-in speakers"), the TV speakers, and the home theater speakers increases in this order.

The operation unit 54 is connected to the controller 63 and transmits/receives data regarding operation input to/from the controller 63 . For example, the user inputs operation signals to the game apparatus 5 by operating operators (not shown) such as buttons provided on the controller 63 .

The storage unit 55 is composed of an HDD, a RAM, a ROM, and the like. The storage unit 55 can store game programs and game data. The storage unit 55 also stores other account information received from other game devices 5 and the like.

Control unit 56 is composed of a microcomputer including a CPU and a semiconductor memory, and controls the operation of game device 5 itself. For example, the control unit 56 operates the graphics processing unit 52 and the audio processing unit 53 by executing the game program.

<Functional Configuration of Control Unit>
The control unit 56 functions as a communication unit 561, a game progression unit 562, a determination unit 563, a determination unit 564, and a reproduction unit 565 by executing the game program.

The communication unit 561 has a function of communicating with another game device 5 via the network interface 51 . The communication unit 561 transmits various operation signals received by the operation unit 54 from the controller 63 to the other game devices 5 .

The game progression unit 562 uses the data read from the storage unit 55 for data such as game space objects and textures included in the game data to execute the game program while executing a two-dimensional or three-dimensional image. game image information. As the game image information is processed by the graphics processing unit 52 , the processed game image is sequentially displayed on the display 61 .

In addition, the game progression unit 562 causes the character to be operated by the user to move in the virtual space according to the user's operation. For example, the game progression unit 562 moves a character according to an operation signal from the controller 63 .

Determining unit 563 determines the type of speaker 62 that reproduces the audio data. For example, when the speaker 62 is externally connected to the game device 5, the determination unit 563 detects a signal from the speaker 62 and determines the type of the speaker 62 (eg, TV speaker, home theater speaker, etc.). . On the other hand, when the speaker 62 is not externally connected to the game device 5, the determination unit 563 determines that the type of the speaker 62 is the built-in speaker.

The determination unit 564 determines the number of pronunciations to be reproduced by the speaker 62 based on the type of the speaker 62 determined by the determination unit 563 .

FIG. 2 is a conceptual diagram of pronunciations included in speech data according to the first embodiment. For example, assume that a monster C1 as a large enemy character, a monster C2 as a medium-sized enemy character, and a monster C3 as a small enemy character are placed in the virtual space. Sound_1 to sound_3 are set as the sounds emitted by the monsters C1 to C3, respectively, and the priorities are set to high to low, respectively.

In this case, if the speaker 62 is a home theater speaker, the determination unit 564 determines that all the sounds of sound_1 to sound_3 are to be reproduced by the reproduction unit 565 . Home theater speakers generally have high performance, so even when many pronunciations are played back at the same time, each pronunciation can be reproduced accurately. That is, when the speaker 62 is a home theater speaker, the determination unit 564 determines that all the pronunciations are to be reproduced by the reproduction unit 565 .

Further, when the speaker 62 is a TV speaker, the determination unit 564 determines that the reproduction unit 565 reproduces sound_1 and sound_2, excluding sound_3 which is a low-priority pronunciation. When a large number of pronunciations are reproduced at the same time, the TV speaker sometimes overlaps some pronunciations with other pronunciations and cannot accurately reproduce each pronunciation. Therefore, when the speaker 62 is a TV speaker, the determination unit 564 determines that the reproduction unit 565 is to reproduce the pronunciation other than the pronunciation with the low priority from the audio data.

Further, when the speaker 62 is the built-in speaker, the determination unit 564 determines that the reproduction unit 565 is to reproduce only sound_1, which has a high priority. A built-in speaker generally has low performance, and in many cases, the number of simultaneous sounds that can be produced is small. Therefore, when the speaker 62 is the built-in speaker, the determining unit 564 determines that only the pronunciation with the highest priority is to be reproduced by the reproducing unit 565 from the audio data.

The reproduction unit 565 reproduces the audio data based on the pronunciation (the number of pronunciations) determined by the determination unit 564 .

(Operation of game device)
A series of operations in the game device will be described with reference to FIGS. 1 to 3. FIG. FIG. 3 is a flow chart showing the operation of the game device 5. As shown in FIG.

First, the determination unit 563 determines the type of the speaker 62 that reproduces the audio data (step S1). Specifically, when the speaker 62 is externally connected to the game device 5, the determination unit 563 communicates with the speaker 62 to determine the type of the speaker 62 (eg, TV speaker, home theater speaker, etc.). On the other hand, when the speaker 62 is not externally connected to the game device 5, the determination unit 563 determines that the type of the speaker 62 is the built-in speaker.

The determination unit 564 determines the number of pronunciations to be reproduced by the speaker 62 based on the type of the speaker 62 determined by the determination unit 563 (step S2).

In the case of FIG. 2, the determination unit 564 determines that all the sounds of sound_1 to sound_3 are to be reproduced by the reproduction unit 565 when the speaker 62 is a home theater speaker. If the speaker 62 is a TV speaker, the determination unit 564 determines that the reproduction unit 565 is to reproduce sound_1 and sound_2, excluding sound_3, which is a low-priority pronunciation. When the speaker 62 is the built-in speaker, the determining unit 564 determines that only the sound_1 having the higher priority is to be played back by the reproducing unit 565 .

The reproduction unit 565 reproduces the voice data based on the pronunciation determined by the determination unit 564 (step S3).

In summary, the game program of the present embodiment causes the game device 5 (computer) to function as a reproduction unit 565 that reproduces audio data and a determination unit 564 that determines audio data to be reproduced by the reproduction unit 565, The data is configured to produce a plurality of pronunciations sound_1 to sound_3, and the determination unit 564 determines the number of pronunciations to be reproduced from the audio data by the reproduction unit 565 based on the speaker 62 (reproduction device) that reproduces the audio data. is determined.

<Effect of invention>
As described above, the determination unit 564 determines the number of pronunciations to be reproduced by the reproduction unit 565 from the audio data based on the speaker 62 that reproduces the audio data. For example, when the performance of the speaker 62 is low, the determining unit 564 determines the number of tones to be reproduced so as to suppress the number of tones to be reproduced, so that the speaker 62 can be made to produce accurate sounds. Thereby, user's interest can be improved.

Further, the determination unit 564 determines the pronunciation to be reproduced by the reproduction unit 565 according to the priority set for the plurality of pronunciations sound_1 to sound_3. By setting high priority to pronunciations that are important for game play (eg, voices of boss monsters, etc.), it is possible to improve the interest of the user.

(Embodiment 2)
In the first embodiment, the determining unit 564 determines the number of pronunciations to be reproduced by the speaker 62 based on the type of the speaker 62.

Note that in the present embodiment, an example in which reverberation processing is performed based on the type of the speaker 62 will be described.

FIG. 4 is a diagram for explaining acoustic processing applied to audio data. 4A to 4C show the state of audio data reproduced based on the type of speaker 62. FIG. FIGS. 4A to 4C show the case where the speaker 62 is a home theater speaker, a TV speaker, and a built-in speaker, respectively.

As shown in FIG. 4(a), when the speaker 62 is a home theater speaker, the audio data added with the impact-enhancing bass, which is the audio for enhancing the bass, is subjected to home theater reverb processing (processing load: high). ) is applied, the audio data is reproduced from the speaker 62 .

Since the home theater speaker includes a plurality of speaker units, it is possible to reproduce different sounds from each speaker unit. Therefore, the determining unit 564 determines to perform reverb processing (home theater reverb processing) with a high processing load on the audio data reproduced from each speaker unit. As a result, it is possible to provide the user with realistic sound.

As shown in FIG. 4B, when the speaker 62 is a TV speaker, the audio data is reproduced from the speaker 62 after being subjected to standard reverb processing (processing load: medium). That is, when the speaker 62 is a TV speaker, the determination unit 564 determines to apply standard reverb processing (standard reverb processing) to the audio data.

As shown in FIG. 4(c), when the speaker 62 is a built-in speaker, the voice data is subjected to treble emphasis effect processing and built-in speaker reverb processing (processing load: low), and then the voice data is transmitted to the speaker. 62 is reproduced.

For example, built-in speakers are inferior in performance to home theater speakers and TV speakers, which limits the amount of sound that can be reproduced accurately. For this reason, the determining unit 564 performs effect processing for emphasizing the treble range (treble emphasis effect processing) on the audio data, and then performs reverb processing with a low processing load according to the characteristics of the built-in speaker (built-in speaker reverb). This makes it possible to reproduce audio data suitable for the built-in speaker.

(Operation of game device)
FIG. 5 is a flow chart showing the operation of the game device 5 in this embodiment. In FIG. 5, step S4 is performed instead of step S2 as compared with FIG.

In step S<b>4 , the determination unit 564 determines the content of reverb processing to be applied to the audio data based on the type of speaker 62 .

In FIG. 4, when the speaker 62 is a home theater speaker, the determination unit 564 determines to perform home theater reverb processing (processing load: high) on the audio data to which the impact-enhancing bass has been added. If the speaker 62 is a TV speaker, the determination unit 564 determines to apply standard reverb processing (processing load: medium) to the audio data. The decision unit 564 decides to apply high-frequency emphasis effect processing and built-in speaker reverb processing (processing load: low) to the audio data.

In summary, the game program of the present embodiment causes the game device 5 (computer) to function as a reproduction unit 565 that reproduces audio data and a determination unit 564 that determines audio data to be reproduced by the reproduction unit 565, The data is configured such that a plurality of pronunciations are performed, and the determining section 564 determines the content of reverb processing (acoustic processing) to be applied to the voice data.

<Effect of invention>
As described above, the determination unit 564 determines the content of reverb processing to be performed on the audio data based on the speaker 62 that reproduces the audio data. For example, by subjecting audio data to reverb processing in accordance with the characteristics of the speaker 62, it is possible to reproduce audio data in accordance with the characteristics of the speaker. Thereby, user's interest can be improved.

Specifically, the determination unit 564 preferentially determines the pronunciation with the loudest volume as the pronunciation to be reproduced by the reproduction unit 565 . For example, a large monster is often a boss monster, and a large volume is set for the pronunciation of the large monster. As a result, sounds that are important for game play (eg, voices of boss monsters, etc.) are preferentially reproduced, so that the interest of the user can be improved. Note that the volume set for the pronunciation may change according to the situation (anger, sleep, etc.) of the monster (character) that emits the pronunciation.

Further, when the determination unit 564 determines the number of sounds to be pronounced, the reproduction unit 565 may emphasize a predetermined band. For example, when the speaker 62 is a home theater speaker, the playback unit 565 emphasizes the bass range. As a result, powerful sound effects can be obtained. Therefore, user's interest can be improved.

Further, in the second embodiment, the case where the acoustic processing is reverb processing (reverberation processing) has been described as an example, but the present invention is not limited to this.

The speaker 62 externally connected to or built into the game device 5 may be of any type, and the determination unit 564 may determine the number of sounds to be produced and the details of sound processing according to the characteristics of the speaker 62 .

Also, the speaker 62 does not necessarily have to be built in the game device 5 , and may be externally connected to the game device 5 .

Further, when a plurality of speakers 62 are connected to the game device 5, the reproducing unit 565 (or the determining unit 564) may select the speaker 62 for reproducing the audio data according to a predetermined priority. This priority may be set by the user or preset. In addition, when the internal speaker has a higher priority than the externally connected speaker, the reproduction unit 565 (or the determination unit 564) reproduces the audio data preferentially from the internal speaker.

Games executed by the game device 5 are of any genre, such as adventure games, action games, FPS (first person shooter), racing games, sports games, RPGs (role-playing games), and shooting games. good too.

Also, the game program may be implemented as a so-called online game game program. When the game program is for an online game, the processing performed by the control unit 56 may be performed on the server side in place of them, or may be shared between the server side and the client (game device 5) side. good. In this case, the game system including the game device 5 may be provided with an authentication server and a matching server, and user matching may be performed in response to a request from the game device 5 .
