Emotion detection using both acoustic and linguistic information in children's speech

27-Oct-2009

Dr. Michael Wagner, director of the National Center for Biometric Studies at the University of Canberra, Australia, has given a speech on emotion analysis at UPC. He has presented their contribution to the Emotion Challenge that was held last September at Interspeech. They proposed the fusion of acoustic and linguistic features in order to detect emotion states in children's speech.

He has proposed the acquisition of a host of acoustic features to get the most out of the plain speech signal, an approach he himself has criticized for being unscientific. With respect to the linguistic characterization of speech they detected a list of emotionally salient words and compared its decision with the one provided by the acoustic module. Although his publication did not win the challenge, their approach is very interesting and innovative since they were the only participating team that considered linguistic features.
