CountVoices

You can determine how many voices are available by calling the CountVoices function.

FUNCTION CountVoices (VAR numVoices: Integer): OSErr;
numVoices
On exit, the number of voices that the application can use.
DESCRIPTION
The CountVoices function returns, in the numVoices parameter, the number of voices available. The application can then use this information to call the GetIndVoice function, described next, to obtain voice specification records for one or more of the voices.

Each time CountVoices is called, the Speech Manager searches for new voices.

SPECIAL CONSIDERATIONS
Because the CountVoices function moves memory, you should not call it at interrupt time.
