SAB allows you to configure the following recognition parameters:
Parameter
Timeout
Barge-in
Complete Timeout
Incomplete
Timeout
Description
The Timeout parameter sets the length of silence that must elapse before the
recognizer returns a value of No Input.
The Barge-in parameter specifies the barge-in setting to be used on this
recognition. Options are:
ON
•
OFF
•
DEFAULT
•
If Barge-in is set to ON here, it is enabled on the entire prompt; if it is set to
OFF here, it can be turned on at a specific point in the prompt using the
BARGE-IN ON command. See page 44.
The Complete Timeout parameter sets the length of silence that must follow the
caller's utterance before the recognizer assumes that the utterance has ended,
and finalizes a result. The result may be a successful recognition or a no-
match.
If Complete Timeout is set too low, the recognizer may timeout before the caller
has finished speaking (for example, in a pause between phrases).
If Complete Timeout is set too high, recognition time will be unnecessarily
increased.
Note that the recognizer times out after Complete Timeout when it has a
complete match to an active grammar; it uses Incomplete Timeout when the
speech is an incomplete match to an active grammar. Complete Timeout
should always, therefore, be set to a slightly lower value than Incomplete
Timeout.
The Incomplete Timeout parameter sets the length of silence that must follow
the caller's utterance before the recognizer finalizes a result. This value is used
when the caller's utterance (prior to the silence) is an incomplete match to all
active grammars. The partial result is classified as a no-match.
Incomplete Timeout is also used when the caller's utterance (prior to the
silence) is a complete match to an active grammar, but it would be possible for
him or her to speak further and still match the grammar.
If Incomplete Timeout is set too low, the recognizer may timeout before the
caller has finished speaking (for example, in a pause between phrases).
If Incomplete Timeout is set too high, recognition time will be unnecessarily
increased.
The Incomplete Timeout should be set to a slightly higher value than Complete
Timeout, to allow callers to pause mid-utterance.
