The need to transcribe infant sound productions from birth onwards by using universally applicable coding tools has been basic to the development of our AMSTIVOC classification system. In this system early infant vocalizations are described by means of a sensori-motor approach based on the source-filter model for speech production. We applied the AMSTIVOC classification system, among other thin...

ABSTRACT Dynamic vocal analysis (DVA) is an auditory-perceptual and acoustic assessment strategy that provides estimates on the biomechanics aerodynamics of production by performing frequency intensity variation tasks using voice spectrography. The objective this experience report to demonstrate use DVA in functionality dysphonic non-dysphonic individuals, with a special focus laryngeal muscula...

Vowel devoicing at phrase boundaries is shown to depend on sentence mode (statement, question) and information structure (non-contrastive vs. contrastive and broad vs. narrow focus), which affect the type of nuclear accent and boundary tone. In li-questions, considerably less devoicing of the vowels before the phrase boundary is found than in other conditions, because the rising boundary contou...

Some details of phonatory biomechanics, meaning the vibratory movements of the vocal folds during phonation, are described in the introduction. Here a special emphasis is laid on the multicomponent structure of the vocal folds. Glottography is a general term used for methods to monitor the vibrations of the vocal folds. Four different types of glottography are generally recognized (fig. 2), viz...

Using inverse filtering, voice source characteristics related to vocal £old adductory force, and the first formant frequency, are analyzed in six professional male singers and six male nonsingers repeatedly phonating the syllable /pae:/ in loud and soft phonation at different fundamental frequencies throughout the subjects' ranges. For each voice sample, inverse filtered air flow was recorded a...
