public TimeSpan MinimumUtteranceDurationToAssumeAnsweringMachine { get; set; }

Property Value

A TimeSpan that contains the minimum length of time of an answerer's response for which an answerer is assumed to be an answering machine. The default value is 4 seconds.

Exceptions

Exception type	Condition
ArgumentOutOfRangeException	An attempt is made to set MinimumUtteranceDurationToAssumeAnsweringMachine to a value less than TimeSpan.Zero.

Remarks

The assumption that underlies this property is that an answering machine message is usually longer than a human's response. A response whose length is longer than MinimumUtteranceDurationToAssumeAnsweringMachine is assumed to come from an answering machine.
