Prediction and synthesis of prosodic effects on spectral balance of vowels

Linguistic control factors such as word stress and phrase-finality affect not only duration and pitch, but also spectral structure and spectral dynamics. We propose methods for predicting and synthesizing prosodic effects on spectral balance: (i) a new multi-dimensional measure of spectral balance, in which energy is measured in five "formant frequency range" bands; (ii) statistical methods for analyzing the effects of multiple interacting factors on spectral balance; (iii) a method for synthesizing speech whose spectral balance is controlled by prosodic factors.
