1. A method for improving the accuracy level of an at least one audio analysis engine designed to process an at least one audio interaction segment captured in an environment, the method comprising the steps of: pre-processing the at least one audio interaction segment, said pre-processing comprising estimating a quality parameter associated with the at least one audio analysis engine; determining to transfer based on the pre-processing results, the at least one audio interaction segment for analysis by the at least one audio analysis engine; analyzing the at least one audio interaction segment by the at least one audio analysis engine, the at least on audio analysis engine providing at least one result based upon the analysis algorithms; post-processing the at least one result of the at least one audio analysis engine processing the at least one audio interaction segment; and based on said post-processing, determining whether to qualify or disqualify, the at least one result, thus improving the accuracy level of the at least one audio analysis engine.
