The present work proposed an approach to characterize the word-final glottal stops in Mizo and Assam Sora language. Generally, glottal stops have more strong glottal and ventricular constriction at the coda position than at the onset. However, the primary source characteristics of glottal stops are irregular glottal cycles, abrupt glottal closing, and reduced open cycle. These changes will not ...

Glottal stops that occur in vowel-consonant-vowel context are often not realized as stops at all, but rather show voicing that is continuous throughout the glottal constriction gesture. Glottal articulations that are realized in this way are apparently marked by reductions in amplitude and fundamental frequency. In the present study measurements from naturally produced utterances containing the...

Hyunsoon Kim, Hongik University Seoul Korea ([email protected] or [email protected]) The present study is concerned with the direct relationship of articulation-based phonological distinctive features, through their acoustic correlates, to perception, based on recent articulatory, acoustic and perception experiments on the three-way laryngeal contrast in Korean consonants. The recent ...

Decreasing epilaryngeal area has been shown to increase glottal flow pulse skewing and harmonic amplitudes [Titze, JASA, 123:2733, 2008]. It is not known, however, whether listeners perceive voice quality changes when epilaryngeal area is altered, or if perceived quality is different if the area change occurs at the ventricular folds or aryepiglottic (AE) folds. In this study, a kinematic vocal...

This research posits a set of phonetic laryngeal features to account for the role of the epilarynx in laryngeal articulation. The focus is to move beyond a ‘glottal’ view of the larynx and beyond the lingual paradigm of pharyngeal articulation to a more ‘global’ view that integrates observations about how the epilaryngeal structure constitutes the locus of constriction in pharyngeal consonants,...

Variation in voicing is common among sounds of the world’s languages: that are analyzed as voiceless can undergo voicing, and those voiced devoice. Among glottal particular, widespread: linguists often expect stop [ʔ] fricative [h] to be fully voiced, especially between vowels. In this study, we use audio recordings from Illustrations International Phonetic Alphabet published Journal Associatio...

"Vowel devoicing" occurs more frequently in the Tokyo dialect (standard Japanese) than in the Osaka dialect. Our previous study showed that devoicing was a) highly frequent when a stop or an affricate was at least on one side, b) less frequent when fricatives were on both sides, and c) infrequent when there was a following /h/. In order to clarify why asymmetric effect of consonantal kind on vo...

Acoustic analyses were conducted to identify the characteristics that differentiate the glides /j,w/ from adjacent vowels. These analyses were performed on a recorded database of intervocalic glides, produced naturally by two male and two female speakers in controlled vocalic and prosodic contexts. Glides were found to differ significantly from adjacent vowels through RMS amplitude reduction, f...

Multiple imaging modalities are used to obtain qualitative and quantitative data on laryngeal height and state during pharyngeal consonant production. Videofluoroscopy provides insight into the relative changes in pharyngeal and epilaryngeal lumina, allowing us to compare the roles these structures play in epilaryngeal constriction. Simultaneous laryngoscopy and laryngeal ultrasound allow us to...

This paper presents a new method of analyzing and quantifying glottalization patterns in speech sounds, demonstrated through an analysis of glottalized stops in Standard German. Acoustic studies have shown that instances of stop glottalization, in which the glottis is assumed to be constricted, can have a range of acoustic correlates, including glottal stops and stretches of irregularity in fun...
