Torbjørn Karl Svendsen
About
Torbjørn Svendsen (1955) is a Professor at the Department of Electronic Systems. Professor Svendsen holds a MScEE, and a PhD both from the NTNU.
Fields of interest and present research activities
My research interests have from the outset in 1979 been speech signal processing. The first period was focused on source coding, i.e. speech compression, which was also the subject of my doctoral thesis. From the mid 80’s the research interests have been mainly on automatic speech recognition, but also areas like spoken dialogue systems and speech synthesis have been included in my research. Speech analysis methods and lexical modelling, e.g. pronunciation modelling have been two central areas. Realizing that current approaches to speech recognition seem to be nearing a saturation point in terms of performance, a major activity in the last 5-year period has been to investigate new paradigms for speech recognition, aiming to integrate phonetic and linguistic knowledge in a statistical framework based on detection of (language universal) phonetic features.
