SpeechInterference Enum

The SpeechInterference enumeration lists possible causes of interference or poor recognition with the input audio stream.

Definition

  Enum SpeechInterference
    SINone = 0
    SINoise = 1
    SINoSignal = 2
    SITooLoud = 3
    SITooQuiet = 4
    SITooFast = 5
    SITooSlow = 6
End Enum

Elements

  • SINone
    Private. Do not use.
  • SINoise
    The sound received is interpreted by the speech recognition engine as noise. This event is generated when there is a SOUND_START followed by a SOUND_END without an intervening PHRASE_START. The event will be also generated during dictation if, after a series of hypotheses, it is determined that the signal is noise.
  • SINoSignal
    A sound is received but it is of a constant intensity. This also includes the microphone being unplugged or muted.
  • SITooLoud
    A sound is received but the stream intensity is too high for discrete recognition.
  • SITooQuiet
    A sound is received but the stream intensity is too low for discrete recognition.
  • SITooFast
    The words are spoken too quickly for discrete recognition.
  • SITooSlow
    The words are spoken too slowly and indicates excessive time between words.
