Definition

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.
