Postural dynamics and vocal effort: preliminary experimental analysis.
OBJECTIVES One postural characteristic of increased vocal effort is stiffening of the whole body, which in turn induces some postural instability. The study of postural instability can shed some insight into behavior or causes associated with vocal hyperfunction. PATIENTS AND METHODS A posturography platform was used to measure the root mean square of the velocity of variation of the center o...
متن کاملExpressing vocal effort in con
A new diphone database with a full diphone set for each of three levels of vocal effort is presented. A theoretical motivation is given why this kind of database will be useful for emotional speech synthesis. Two hypotheses are verified in perception experiments: (I) The three diphone sets are perceived as belonging to the same speaker; (II) The vocal effort intended during database recordings ...
متن کاملAn EGG study on global and local vocal effort changes in German: preliminary results
The aims of this study are (1) to compare the effects of global vocal effort changes on voice source parameters with effects of focus and word stress, (2) to tease apart the influences of subglottal pressure and vocal fold tension by independently varying sentence accent and word stress. Therefore two EGG experiments were carried out. Results on the calculated voice source parameters indicate t...
متن کاملPerception of Vocal Effort and Speaker Distance
The sound pressure level (SPL) of vowels received by a listener reflects several non-linguistic and linguistic factors: It varies as a function of distance, vocal effort, and vowel quality. Increased vocal effort involves, in addition to an increase in SPL, an emphasis of higher frequency components and increases in F0 and F1. This should allow listeners to distinguish it from decreased distanc...
متن کاملAerodynamic and acoustic features of vocal effort.
OBJECTIVES The purpose of this study was to determine the aerodynamic and acoustic features of speech produced at comfortable, maximal and minimal levels of vocal effort. STUDY DESIGN Prospective, quasi-experimental research design. METHOD Eighteen healthy participants with normal voice were included in this study. After task training, participants produced repeated syllable combinations at...
