This paper addresses the problem of stabilization non-minimum phase switched nonlinear systems where internal dynamics with symmetries or non-symmetries each mode may be unstable. The authors initially build a stabilizing Lyapunov controller for in order to stabilize its own unstable dynamics. proposed approach is based on exact input-output feedback linearization technique and stability theory...

In this study three different prominence and speech melody related effects on voice quality were studied using an inverse filtering based method. The hypothesis that prominence as a function of sentence and word stress is signaled with more pressed voice quality was tested. The results indicated discrepancies in the parameterization results, and the original hypothesis could not be confirmed. I...
