The aim of this paper is to present the notion of a hierarchy of articulatory dimensions and its application in phonetic typology. To calculate the hierarchies a computer application was designed, and preliminary counts were carried out on the phonetic repertories of Chinese, Hindi and Polish.

The aim of this paper is to find a multiple window estimator that is mean square error optimal for cepstrum estimation. The estimator is compared with some known multiple window methods as well as with the parametric AR-estimator. The results show that the new estimator has high performance, especially for data with large spectral dynamics, and that it is also robust against parameter choices. Simulated...
