Head of School, School of Electrical Engineering and Telecommunications

 

Research interest

 

Level 1: I develop signal processing techniques to automatically identify emotions from speech recorded by a microphone, identify the language spoken, and verify the claimed identity of a speaker.

Level 2: From a sampled speech utterance, I extract time and frequency domain features that can be modelled to identify the language spoken and what was said, the accent of the speaker, the emotion of the speaker and identify the speaker themselves.

Level 3: I develop systems with innovative, robust front-end short-term acoustic feature extraction and novel modelling and variability compensation methods, for application in real time linguistic and paralinguistic speech classifiers.

Interest in engineering

Why did you get into engineering?

Engineers are innovators and I enjoyed design challenges, so engineering was the natural choice for me to combine design and innovation.

What are your research goals?

To be able to contribute to the future of Australia by providing better language identification systems that suit Australia’s growing multicultural and diverse society.

What do people not understand about you do?

My role is split in 3 ways: to conduct ground-breaking research, to teach and educate the next generation of students using innovative educational technology and to grow the capability of the School and lead its path into the future in my role as Head of School. Executing these 3 responsibilities effectively and simultaneously is a balancing act.

Advice for prospective Electrical and Telecommunications engineers

Engineering is an integral part of Australian and the global society. To develop a skill set that is transferable and to be involved in changing and growing the world we live in, electrical engineering is a career path that allows all of these things to happen.
