Journal ArticleDOI
Ergonomic conditions and voice: Paper presented at PEVOC-II conference, August 29-31 1997, in Regensburg, Germany
TL;DR: This paper presented at PEVOC-II conference, August 29-31 1997, in Regensburg, Germany, a paper on Ergonomic conditions and voice, which was presented at the PVOII conference in 1997.
Journal ArticleDOI
Monopitched expression of emotions in different vowels
TL;DR: The role of voice source characteristics and formant frequencies in the communication of emotions in monopitched vowel samples [a], [i:] and [u:], and the interplay between voice source and F1–F4 warrants a synthesis study.
Journal ArticleDOI
Bandwidth Extension of Telephone Speech to Low Frequencies Using Sinusoidal Synthesis and a Gaussian Mixture Model
TL;DR: A method that extends the bandwidth of telephone speech to the frequency range 0-300 Hz and generates the lowest harmonics of voiced speech using sinusoidal synthesis, which provides adaptivity to varying input bandwidth characteristics.
Journal ArticleDOI
Dynamic extremes of voice in the light of time domain parameters extracted from the amplitude features of glottal flow and its derivative.
TL;DR: The aim was to investigate the dynamic extremes of the human voice in terms of F₀, SPL, fac, dmin, AQ and NAQ as well as the intraoral pressure used for subglottal pressure estimation.
Journal ArticleDOI
Magnetic fields evoked by speech sounds in preschool children.
TL;DR: The results suggest that both EPs and EFs are feasible for investigating the neural basis of sound discrimination in young children, and the recording of EFs with its high spatial resolution reveals information on the location of the activated neural sources.
