completetimeout
This property specifies the required length of silence following user speech before the recognizer finalizes a result (either accepting it or throwing a nomatch event.) The completetimeout property is used when the speech prior to the silence matches an active grammar.
A long completetimeout value delays the result completion and therefore makes the system's response slow. A short completetimeout value may lead to the inappropriate break up of an utterance. The default value is 0.25s. For details, see Appendix D—Timing properties in the VoiceXML specification.
Note: Values set for the completetimeout property are only supported if they are less than the values set for the incompletetimeout property.
