Signal and Acoustic Modeling for Speech and Communication Disorders
This chapter is in the book Signal and Acoustic Modeling for Speech and Communication Disorders

Abstract

This chapter presents three Praat scripts developed for analyzing prosodic acoustic parameters as an aid for acoustic science on prosody modeling and for determining the correlation of prosody production and perception in normal and pathological speech. The SGdetector script assists in language-mediated, semiautomatic identification of syllable-sized normalized duration peaks for investigating prominence and boundary marking. The ProsodyDescriptor script delivers 14 prosodic factors accompanied with duration, F0 and spectral importance, whereas the ExpressionEvaluator script computes additional descriptors of F0 and adds global intensity and long-term spectral parameters useful for expressive speech research. All three scripts have been applied successfully for the study of rhythm, intonation and voice quality for the analysis of expressive and pathological speech as well as for assessing the vocal profile analysis scheme (VPAS) protocol. All scripts are freely available and the languages tested so far were French, German, Swedish, English, Brazilian Portuguese (BP), and European Portuguese.
