acoustic analysis of sounds produced during speech provides significant information about the physiology of larynx and vocal tract. the analysis of voice power spectrum is a fundamental sensitive method of acoustic assessment that provides valuable information about the voice source and characteristics of vocal tract resonance cavities. the changes in long-term average spectrum (ltas) spectral ...

providing a high-quality service for transmission and playing real-time voice conversations (voice streaming) over wireless ad-hoc networks is no mean feat. buffering together with adjusting the playout time of the packets is a receiver-side solution to overcome this challenge. in this paper, a new adaptive playout adjustment algorithm is proposed to stream the voice conversations over wireless...

Introduction: Rhinosinus polyposis is associated with voice quality reduction. There has been little evidence about the efficacy of rhinosinus polyps surgery on patients' voice quality so far. The aim of the present study was to evaluate the nasality and acoustic voice changes after rhinosinus polyposis surgery.   Materials and Methods: The population in this study compo...

the present study explored the intensity level of authorial voice in relation to the quality of argumentative writing. 42 undergraduate learners of english as a foreign language (36 girls and 6 boys) spent 45 minutes to individually complete in-class position-taking writing tasks for three weeks. their overall academic writing quality scores assigned based on portfolio assessment were studied i...

results certain correlations were found between fundamental frequency in vowel and total vhi, physical, functional and emotional domains of vhi in group 1 (r = 0.636, 0.649, 0.613 and 0.592 respectively). there was good correlation between speaking fundamental frequency and total vhi and its subscales - except the physical subscale - were also correlated. in group 2, the correlations between ji...

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...

‘whistleblowing’ has come to increased prominence in many health systems as a means of identifying and addressing quality and safety issues. but whistleblowing – and the reactions to it – have many complex and ambiguous aspects that need to be considered as part of the broader (organisational) cultural dynamics of healthcare institutions.
