Microsoft Speech API 5.4

SPWAVEFORMATTYPE

SPWAVEFORMATTYPE is used in the ISpRecognizer::GetFormat method (as SPSTREAMFORMATTYPE) to request either the input format for the original audio source or, the format actually arriving at the speech engine. SAPI may be performing on the fly conversion using an SpStreamFormatConverter in-between which will cause the two formats to differ.

typedef enum SPWAVEFORMATTYPE
{
    SPWF_INPUT,
    SPWF_SRENGINE
} SPSTREAMFORMATTYPE;

Elements
