The following paper examines a possibility of applying phone-pronunciation variability descriptors in emotion classification. The proposed group of descriptors comprises a set of statistical parameters of Poincare maps, which are derived for evolution of formant-frequencies and energy of voiced-speech segments. Poincare maps are represented by means of four(More)
An objective of the following paper is to examine feasibility of using vowel pronunciation variability as a descriptor of an emotional state of a speaker. Variability is assessed using Poincare Maps, constructed for pitch-synchronized speech segments that correspond to the vowel "a ". Recognition phase of the proposed approach involves an application of(More)
