Both the noise and vocal power level of crowd are parameters for evaluating acoustic environment. The former is from perspective environment, latter user's needs. This paper aims to explore diners in large college canteens China. Measurements were conducted two typical Chinese canteens. Videos also recorded analyse diners’ behaviour. results showed that varied 61 dBA 73 during meal. It was note...

Many aspects of speech production have been successfully described by a linear sourcefilter theory. Linearity implies that the source-filter combination, which provides the acoustic output at the mouth, can be characterized by mathematical convolution in the time domain (or by multiplication in the frequency domain) of two independent functions representing the source and the filter. With this ...

To compete over limited parental resources, young animals communicate with their parents and siblings by producing honest vocal signals of need. Components of begging calls that are sensitive to food deprivation may honestly signal need, whereas other components may be associated with individual-specific attributes that do not change with time such as identity, sex, absolute age and hierarchy. ...

in this paper, first, an initial feature vector for vocal fold pathology diagnosis is proposed. then, for optimizing the initial feature vector, a genetic algorithm is proposed. some experiments are carried out for evaluating and comparing the classification accuracies which are obtained by the use of the different classifiers (ensemble of decision tree, discriminant analysis and k-nearest neig...

this paper reports on a behavioral study that explores the role of culture and gender in the recognition of emotional speech in an under investigated cultural context (a collectivist society: i.e., iran). participants were asked to recognize the emotional prosody of a set of validated emotional vocal portrayals (including the five basic emotions). findings of the experiment were then compared w...

Emotional Finnish speech: a contradiction in terms? Stereotypical views aside, emotional expression does exist in spoken Finnish, as in all languages. The vocal repertoire may be somewhat more limited than in some other languages, Finnish hardly being an intonation language par excellence, but recent evidence shows that, at least at the nonintonational level, there are systematic vocal features...

Design: A pre-test–post-test design was completed in order to determine if an extended Lee Silverman Voice Treatment (LSVT) program (LSVT-X) results in significant increases to vocal sound pressure level (SPL) and significant functional improvement in communication. LSVT-X results for vocal SPL and a perceptual rating of speech were then compared with the results of a previous study examining t...
