1. A method for automatically sectioning an audio signal of an interaction held in a call center, into sections representing the flow of the interaction, the method comprising the steps of: receiving the audio signal from a logging and capturing unit associated with the call center; performing audio analysis on the audio signal for obtaining run-time data; segmenting the audio signal into at least one context unit; extracting a feature vector comprising at least one run-time feature of the at least one context unit, using the run-time data; classifying the at least one context unit using a sectioning model and the feature vector, to obtain at least one section label to be associated with the at least one context unit; and grouping context units assigned identical labels into one section.
