Data Structures

Speech Extension Data Records

The speech extension data record allows you to use the GetSpeechInfo and SetSpeechInfo functions with selectors defined by particular synthesizers. By requiring that you pass to one of these functions a pointer to a speech extension data record, synthesizers can permit the exchange of data in any format. The SpeechXtndData data type defines a speech extension data record.

TYPE SpeechXtndData =
RECORD
   synthCreator:     OSType;     {synthesizer creator ID}
                                 {data used by synthesizer}
   synthData:        PACKED ARRAY[0..1] OF Char;
END;

Field Description
