This paper concerns the relationships amongst acoustic phonetic features of speech signals, perceived vocal effort, and speech clarity. It is presented from a statistical analysis of a good number of subjective testing on an anechoic speech corpus with 5 different vocal efforts, namely hushed, normal, raised, loud, and shouted, with an aim to map objective acoustic phonetic features onto subjec...

Acoustic models of emotions may benefit from considering the underlying voice production mechanism. This study sought to describe emotional expressions according to physiological variations measured from the inverse-filtered glottal waveform in addition to standard parameter extraction. An acoustic analysis was performed on a subset of the /a/ vowels within the GEMEP database (10 speakers, 5 em...

This study presents a comparative analysis of acoustic and perceptual cues to place of articulation in English fricatives. Acoustic parameters investigated include spectral peak location, spectral moments, locus equations, F2 onset, overall noise amplitude, relative amplitude, and fricative noise duration. Perception data were collected for isolated fricatives and fricativevowel syllables. The ...
