## osVoiceSetWord

Syntax

    #include <ultra64.h>

    s32 osVoiceSetWord(OSVoiceHandle *hd, u8 *word)

Explanation
The osVoiceSetWord() function is for registering words in the Voice Recognition System dictionary.

hd is the Voice Recognition System control structure. The Voice Recognition System must be initialized with the osVoiceInit() function before the osVoiceSetWord() function is called. The word (SJIS) to be registered is specified in "word." The word can be up to 17 characters long. Since calling the osVoiceSetWord() function once registers one word, execute osVoiceSetWord() multiple times to register multiple words. The number of words registered must match the number set by the osVoiceClearDictionary() function. Please note that an error will be generated when the osVoiceStartReadData() function is executed, if the number of words registered is greater than or less than the specified number of words.

The maximum number of words which can be registered in the dictionary is about 80 words, assuming 5 syllables per word. Therefore, while the maximum number of words which can be registered is set at 255, if there are several syllables per word, the dictionary may subsequently overflow the memory. In this case, voice recognition can be executed without an error being caused by the osVoiceStartReadData() function even if the number of registered words is less than the number set by the osVoiceClearDictionary() function.

The characters which can be registered and their codes are shown in the table below.

In addition, the following restrictions apply to character combinations when registering words. Use the osVoiceCheckWord() function to check whether or not the word that you are trying to register can be registered in the Voice Recognition System. Use this in the case of game applications in which registered words will be input during debugging or by the game player.

Usage | Character
No limitation on use |
Can be used only after specified characters (Combinable characters) |
Cannot be used at the beginning of a word |
Cannot be used at the end of a word |
Cannot be used in front of "—" |
Cannot be used after "tsu" or "tsu" |
Combinations which cannot be used |

The returned value is an error code. A 0 (zero) is returned when processing ends normally. If an error occurs, this function has the following error codes.

CONT_ERR_NO_CONTROLLER
Nothing is connected to the controller port.

CONT_ERR_DEVICE
Something other than the Voice Recognition System is connected to the controller port.

CONT_ERR_VOICE_NO_RESPONSE
There was no response from the Voice Recognition System. There may be a problem with the hardware.

CONT_ERRO_CONTRFAIL
There was a data transmission failure. There is a problem in the Voice Recognition System connection.

CONT_ERR_INVALID
There is an error in the function call method or in the argument. This error will not occur if the function is being used correctly. Write your program so that this error does not occur when development is completed.

CONT_ERR_VOICE_WORD
A word containing improper characters has been registered. The set word is invalidated and the word number is not incremented. Execute the osVoiceSetWord() function to register a proper word.

CONT_ERR_VOICE_MEMORY
Dictionary memory overflow. However, if the recognition command is executed in this condition, normal recognition processing can be performed even if the number of words which have been set is less than the number of words set by the osVoiceClearDictionary() function. When this error is generated, manage the number of words actually set on the application side.
