objectives: nasality is one of the important parameters in pathology of voice resonance. voice of normal adults has nasality to some extent. it appears that nasality, like other parameters of voice, can be affected by loudness which can be measured in experimental evaluations. this study was conducted to determine the effect of vocal loudness on nasalance of vowels in normal adults and to ident...

This study was designed to determine the effect of stimulated vocal loudness on nasalance in individuals with various dysarthria subtypes. Thirty participants produced three stimulated levels of vocal loudness while reading a nonnasal passage. Data included dysarthria classification, vocal sound pressure level, nasalance, and listener perception of nasality. There was not a predictable relation...

The vertical position of the larynx seems to be relevant to voice function. As a high vertical larynx position is often seen in hyperfunctional and strained voices, a lowering of a habitually elevated larynx is sometimes a specific goal in clinical voice therapy and different larynx-lowering exercises are used to achieve this goal. Earlier investigations have shown that pitch and to some extent...

BACKGROUND contextual cues intrinsic to speech stimuli can have an influence on speech intelligibility measurements; however, the influence of cues that depend on the acoustic signal, such as speech rate and vocal loudness, need further investigation. AIM to examine whether possible reductions in the articulatory rate and increase in vocal loudness, associated to the production of different s...

BACKGROUND Vocal rehabilitation of patients with idiopathic Parkinson disease. AIM To describe the interfering factors in the vocal rehabilitation of five individuals with Parkinson disease and to present the modifications in the oral communication. METHOD Interviews and pre and post vocal treatment assessments were carried out using the Lee Silverman Voice treatment method (LVSTO). RESUL...

Voice source characteristics as derived from inverse filtering were analyzed in 6 country singers' speech and singing. Results showed that the closed quotient varied systematically with vocal loudness, and that glottal compliance (the ratio between transglottal AC volume displacement and subglottal pressure) decreased with increases in fundamental frequency but remained unaffected by vocal loud...
