The QUT NIST 2004 Speaker Verification System: A Fused Acoustic and High Level Approach
Brendan Baker, Michael Mason, Subramanian Sridharan, Robert Vogt · 2004
The trend towards including both acoustic and high level speech features in speaker recognition systems is addressed with the presentation of the speaker verification system developed by QUT for the NIST 2004 Speaker Recognition Evaluation. The system presented is a fusion of five subsystems including acoustic, lexical, phonetic, prosodic and durational speech features and focuses on utilising the high level feature sets in reduced training set conditions. The performance of the system on the development data resources available in the NIST SRE are presented to demonstrate the effectiveness of the fused system approach.
