Applications of Artificial Intelligence in Neurological Voice Disorders

open access: yesWorld Journal of Otorhinolaryngology - Head and Neck Surgery, EarlyView.
ABSTRACT Neurological voice disorders, such as Parkinson's disease, laryngeal dystonia, and stroke‐induced dysarthria, significantly impact speech production and communication. Traditional diagnostic methods rely on subjective assessment, whereas artificial intelligence (AI) offers objective, noninvasive, and scalable solutions for voice analysis. This

Determination of Formant Features in Czech and Slovak for GMM Emotional Speech Classifier [PDF]

open access: yes, 2013
The paper is aimed at determination of formant features (FF) which describe vocal tract characteristics. It comprises analysis of the first three formant positions together with their bandwidths and the formant tilts.

Extraction of vocal-tract system characteristics from speechsignals [PDF]

open access: yes, 1998
We propose methods to track natural variations in the characteristics of the vocal-tract system from speech signals. We are especially interested in the cases where these characteristics vary over time, as happens in dynamic sounds such as consonant ...

Low frequency groans indicate larger and more dominant fallow deer (Dama dama) males. [PDF]

open access: yesPLoS ONE, 2008
BACKGROUND: Models of honest advertisement predict that sexually selected calls should signal male quality. In most vertebrates, high quality males have larger body sizes that determine higher social status and in turn higher reproductive success ...

Loanwords and Linguistic Phylogenetics: *pelek̑u‐ ‘axe’ and *(H)a(i̯)g̑‐ ‘goat’1

open access: yesTransactions of the Philological Society, Volume 123, Issue 1, Page 116-136, March 2025.
Abstract This paper assesses the role of borrowings in two different approaches to linguistic phylogenetics: Traditional qualitative analyses of lexemes, and quantitative computational analysis of cognacy. It problematises the assumption that loanwords can be excluded altogether from datasets of lexical cognacy.

Impact of prominence type on the coarticulation of vowels following palatalized consonants

open access: yesВестник Самарского университета: История, педагогика, филология
The quantitative impact of prominence (neutral vs emphatic stress) on the coarticulation of the Russian low [æ], mid [e] and high [i] front vowels is evaluated in CV sequences with palatalized consonants of various places of obstruction.

The Development of Indo‐Iranian Voiced Fricatives

open access: yesTransactions of the Philological Society, Volume 123, Issue 1, Page 97-115, March 2025.
Abstract The development of voiced sibilants is a long‐standing puzzle in Indo‐Iranian historical phonology. In Vedic, all voiced sibilants are lost from the system, but the details of this loss are complex and subject to debate. The most intriguing development concerns the word‐final ‐aḥ to ‐o in sandhi.

A Chinese alligator in heliox: formant frequencies in a crocodilian

open access: yesJournal of Experimental Biology, 2015
Crocodilians are among the most vocal non-avian reptiles. Adults of both sexes produce loud vocalizations known as ‘bellows’ year round, with the highest rate during the mating season. Although the specific function of these vocalizations remains unclear,

Second formants in fricatives [PDF]

open access: yesThe Journal of the Acoustical Society of America, 1981
Acoustic analyses of the sibilant fricatives, [s, z, ∫, ȝ], produced in initial position before [a], [i], and [u] were performed. LPC spectra revealed reliable anticipatory vowel coarticulation effects, viz., spectral peaks affiliated with the second formant of the following vowel, present 30–60 ms before vowel onset.
