Elements

SPINTERFERENCE_NONE

Private event. Do not use.

SPINTERFERENCE_NOISE

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.

SPINTERFERENCE_NOSIGNAL

A sound is received but it is of a constant intensity. This also includes the microphone being unplugged or muted.

SPINTERFERENCE_TOOLOUD

A sound is received but the stream intensity is too high for discrete recognition.

SPINTERFERENCE_TOOQUIET

A sound is received but the stream intensity is too low for discrete recognition.

SPINTERFERENCE_TOOFAST

The words are spoken too quickly for discrete recognition.

SPINTERFERENCE_TOOSLOW

The words are spoken too slowly and indicates excessive time between words.
