Configuring Non-Linguistic Event Elements
Non-linguistic Events include various sounds that SpeechMiner detects in a call, such as busy tones, key presses, and music or noise. Depending on the Program settings of the call, non-verbal indications of agitation may also be detected. In addition, the non-linguistic Event called Cross Talk is identified when two speakers are talking at the same time. This type of Event can only be identified in systems in which dual-channel recording is employed.
In some cases, an element can include more than one type of related Event. For example, you can select Silence, Busy Tone, and Dial Tone together, but you cannot select Agitation along with other types of Events. When you select multiple types of non-linguistic Events, if any of those Events is found in the call, it meets the condition.
When you add a non-linguistic Event element to an expression (see Inserting Elements into an Expression), the fields required to select and configure the element are added to the right panel below the Type field. You can use these fields to select the type of non-linguistic Event and specify what proportion of the call must contain this type of Event and when it must be detected in the call.
To configure a non-linguistic Event element:
