Alessio Brutti

Head of Unit

    Short bio

    Alessio Brutti is a tenured researcher at FBK. He is currently the head of the SpeechTek research unit of the Centre for Information Technology. After graduating in Telecommunication engineering at the University of Padova in 2001, in 2003 he joined FBK-irst being part of the SHINE research group. In 2007 he completed his PhD in Computer Science at University of Trento. He collaborates with the Faculty of Education of the University of Bolzano for the master degree in computational linguistics.
    His research interests focus mainly on the use of machine learning approaches for digital audio and speech processing, including: speech recognition, speaker verification and recognition, speech enhancement, source localization and sound event detection. In particular, his research addresses the development of efficient, compact and dynamic neural models. Recently, he has been investigating multi-modal signal processing for audio-video person tracking and for biometrics. In 2015 he was visiting researcher at Queen Mary University London (Center for Intelligent Sensing).
