Learning outcomes
|
The course deals with digital processing of acoustic signals. The first part of course is aimed at signal analysis and digital processing techniques. The course includes speech processing, acoustic signal recording, speech recognition and systems for sound source azimuth and position determination. In the practical part, students will work on two semester projects in Matlab environment.
Acoustic signal processing, overview of acoustic systems for speech processing and localization.
