This has application in, e.g., hearing aids and teleconference systems. We consider a\u00a0signal-driven approach to speech enhancement where a model of the speech is assumed and filters are generated based on this model. The basic model used in this thesis is the harmonic model which is a commonly used model for describing the voice d speech part of the speech signal. We show that it can be beneficial to extend the model to take inharmonicities or the\u00a0non-stationarity of speech into account. Extending the model introduces\u00a0extra parameters and we suggest methods to estimate these extra parameters and derive filters based on the extended models.<\/p>\n<p>The Ph.D. assessment committee is<\/p>\n<ul>\n<li>Professor Stefani a Serafin (Chairman), Aalborg University<\/li>\n<li>Professor Ioannis (Yannis) Stylianou, University of\u00a0Crete<\/li>\n<li>Reader Wenwu Wang,\u00a0University of Surrey<\/li>\n<\/ul>\n<p>The work was supervised by Jesper Rindom Jensen and Mads Gr\u00e6sb\u00f8ll Christensen.<\/p>\n<p>The defense will take place\u00a0at 1 pm at\u00a0Rendsburggade 14, room 3.429, 9000 Aalborg.
