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...

In this paper we study the problem of linearly equalizing the Multiple Input Multiple Output (MIMO) communications channels from an H∞ point of view. H∞ estimation theory has been recently introduced as a method for designing filters that have acceptable performance in the face of model uncertainty and lack of statistical information on the exogenous signals. In this paper we obtain a closed-fo...

Prominence relations in speech are signaled by various ways including such phonetic means as voice fundamental frequency, intensity, and duration. A less studied acoustic feature affecting prominence is the so called voice quality which is determined by changes in the airflow caused by different laryngeal settings. We investigated the changes in voice quality with respect to linguistic prosodic...

Analysis and design algorithms for residual generators for non minimum phase systems are given. It is shown that Rm optimization of residual generators applied directly to systems including non m i n i u m phase zeros can be very conservative. To remove this conservatism in the H, optimization of the residual generators, a factorization of the non minimum phase system into a minimum phase part ...
