Análise Exploratória de Dados Lingüísticos para uma Modelagem Linear Robusta da Duração Segmental da Fala

Edmilson S. MoraisFábio Violaro

In this work a new method based on exploratory analysis of linguistic data is proposed in order to improve the performance of regression methods for predicting segmental duration of speech. The improved prediction method must be able to perform robust mappings from a linguistic feature space (syntactical, prosodical and phonological features) into a continuous interval of phoneme durations. The proposed method can be usefull for both purelly linguistic analysis and Text-To-Speech synthesis systems. The proposed method was evaluated using a database from the Toshiba Speech Technology Laboratory in Cambridge, UK.
