SpeechFormatType (SAPI 5.4)

Microsoft Speech API 5.4

SpeechFormatType Enum

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


  • SFTInput
    Request the format of the original audio input.
  • SFTSREngine
    Request the format received by the SR engine.
