Missing-data model of vowel identification.
Vowel identity correlates well with the shape of the transfer function of the vocal tract, in particular the position of the first two or three formant peaks. However, in voiced speech the transfer function is sampled at multiples of the fundamental frequency (F0), and the short-term spectrum contains peaks at those frequencies, rather than at formants. It is not clear how the auditory system e...
متن کاملThe influence of spectral prominence on perceived vowel quality.
Research indicates that, when the first and second formants of a vowel are separated by less than about 3.5 Bark, perception of its height and some other aspects of its quality is determined by some weighted average of the low-frequency spectrum, rather than by particular harmonic or hypothetical formant frequencies (as is the case with more widely spaced formants). This spectral averaging has ...
متن کاملClassification of Peterson & Barney's vowels using Weka
Gordon Peterson and Harold Barney describe a detailed investigation of sustained American English vowels in [1]. The article presents acoustic measurements of fundamental frequency (F0) and first three formant frequencies (F1-F3). The authors also conducted experiments where listeners were asked to identify words. Raymond Watrous [2] re-organized the database collected in [1] and made it tempor...
متن کاملAuditory Processing of Speech : The COG Effect
The “COG effect” is an auditory phenomenon in which a human listener can perceive the spectral center of gravity (COG), or centroid, of a frequency band up to 3.5 Bark wide. Engineering applications of this effect include extracting centroid features for use in speech recognition algorithms. This work investigates the representation of the spectral centroid in the auditory system using a comput...
متن کاملParalinguistic variation and invariance in the characteristic frequencies of vowels.
It is shown that within-speaker variations in vocal effort and phonation affect fundamental frequency (F0) and the formant frequencies of vowels in the sense of a linear compression/expansion of the spectral separations between them, given an adequate scaling of pitch. Between-speaker variations in size correspond to a translation of the spectral peaks shaped by F0 and the formants if pitch is ...
