SpeechFormatType (SAPI 5.4)
Microsoft Speech API 5.4
The SpeechFormatType enumeration requests either the input format for the original audio source, or the format that actually arrives at the speech engine.
SAPI may be dynamically converting the stream to a different format and as a result, the original stream format may be different than the format received by the speech recognition (SR) engine.
Enum SpeechFormatType SFTInput = 0 SFTSREngine = 1 End Enum
Request the format of the original audio input.
Request the format received by the SR engine.
