Hannah Muckenhirn

Short Biography

I am a Phd student at the Idiap research institute and Ecole Polytechnique Federale de Lausanne, under the supervision of Mathew Magimai-Doss and Sebastien Marcel. The main goal of my PhD is to develop speaker recognition systems robust to presentation attacks by jointly learning relevant features and classifier from the raw speech signal with deep learning approaches, as well as understand the discriminative information learned by such systems.

Research interests: speaker recognition, spoofing attack detection, machine learning, audio/speech processing.


2014: Master in Communication Systems, Ecole Polytechnique Federale de Lausanne.
