SPINTERFERENCE

SPINTERFERENCE lists possible causes of interference or poor recognition with the input stream.

  
    typedef enum SPINTERFERENCE
{
    SPINTERFERENCE_NONE,
    SPINTERFERENCE_NOISE,
    SPINTERFERENCE_NOSIGNAL,
    SPINTERFERENCE_TOOLOUD,
    SPINTERFERENCE_TOOQUIET,
    SPINTERFERENCE_TOOFAST,
    SPINTERFERENCE_TOOSLOW
} SPINTERFERENCE;

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.
