A study of invariant properties and variation patterns in the converter/distributor model for emotional speech.

Abstract

Invariant properties of vocal organ controls at an abstract level are crucial for better understanding and modeling of the speech production mechanism. Despite the large variability of articulatory movements at the execution level, the Converter/Distributor (C/D) model provides a systematic and comprehensive framework for the prosodic organization of speech production, based on the invariant properties of articulatory movements with the concept of “iceberg” region. The goal of this paper is two-fold:(i) to examine the invariant properties in the C/D model in emotional speech, and (ii) to understand emotion-dependent variation patterns of important parameters in the C/D model framework. Experimental results support the validity of strong linear relationship between the speed and excursion of critical articulators at the iceberg points for emotional speech. Also, emotion-dependent variation patterns of the C/D model …
