Abstract

In this work prosodic information is considered in order to improve current state-of-the-art Automatic Speaker Verification (ASV) systems. A system based on pitch and energy curves is combined with a traditional MFCC based one to determine whether simple short-term prosodic information is useful. Experiments carried out over read speech show that there is not significant improvement in using short-term prosody. Results are presented and discussed.
