Speech recognition uses only the IRE_INPUT_DONE event for the following reasons:

1. Recognition input is delivered from the voice cards automatically.
2. When recognition completes, it is done; there is no more input from the recognizer until it is restarted.

Note:
The IRE_INPUT event is never used for speech recognition.

This differs from touch-tone input where touch tones arrive from the voice cards one at a time and touch tones are continuously being recognized by those cards.

With touch-tone input, the IRE_INPUT_DONE event is generated when conditions on the input queue are met or the touch-tone timer expires. With speech recognition input, IRE_INPUT_DONE is generated regardless of the conditions on the input queue. The input length or delineators settings do not effect the generation of the IRE_INPUT_DONE event in this case.
