Integrate a sentiment analyzer

A sentiment analyzer based on voice profiling and analysis was integrated with the ASR to understand customer emotions and gauge their sentiment based on the tone, pitch, stress, tempo, and choice of words. The sentiment analyzer classified calls into positive, negative, and neutral segments. The sentiment analyzer was used to derive insights not only into the customer sentiment but also into the response behavior of the customer care executive.
