Conflict of interest: non-existent fricative consonants1-6. In normal morphological and/or functional conditions, these consonants are produced with partial constriction of the airway between the tongue apex and the alveolus, and they may be voiced (with vibration of vocal folds, [z]) or unvoiced (without vibration of vocal folds, [s]). Acoustically, voiced fricatives are characterized by the p...

Implosive consonants have drawn the attention of researchers over time, partially due to their relative rarity in world’s languages, and unique ingressive air flow. This sound category has varying complex features from an articulatory acoustic perspective. study explores by analyzing a language whose implosives yet be acoustically considered: Shimaore, Bantu-Sabaki spoken Mayotte. Specifically,...

BACKGROUND Male-to-female transsexual (MFT) persons often attempt to produce a female-sounding voice as part of the transition process. Endoscopic and stroboscopic data about how they accomplish this with an anatomically male larynx are lacking. OBJECTIVES To describe vocal fold activity in MFT persons producing their feminine voice and identify signs of vocal misuse or hyperfunction in MFT s...

We present a model for forced oscillatory motion of vocal folds. In this model, we incorporate oscillatory motion of the glottis by considering the moments of glottis about its fulcrum point which is very similar to seesaw motion. By changing the position of the fulcrum point, we can have different scenarios for the motion of the glottis. Forced oscillatory motion of vocal folds, together with ...

This paper presents a study on the acoustic sub-segmental properties of word-final /t/ in conversational standard Dutch and how these properties contribute to whether humans and an ASR system classify the /t/ as acoustically present or absent. In general, humans and the ASR system use the same cues (presence of a constriction, a burst, and alveolar friction), but the ASR system is also less sen...

It shows t...

Glottalization of coda /t, p/ is a common process in American English. This study uses acoustic measures to determine when coda glottalization occurs in the conversational speech of the Buckeye Corpus. Vowels preceding coda /t, p/ tokens for 40 speakers were analyzed using H1*–H2*, an acoustic correlate of glottal constriction. Results indicate that coda glottalization is more common before a s...

in this research, we investigated the glottal wave of persian vowels, using electroglottography. in the first level, the properties of vowels glottal wave were analyzed. in the second level, the glottal wave between male and female speakers were  compared. contact quotient is the glottal wave parameter which was analyzed. data included six persian vowels and the glottal wave recorded using elec...

Research on the acoustic characteristics of Infant Directed Speech (IDS) in North American English indicates that it is generally higher-pitched than Adult (ADS) and has unique prosodic characteristics, which commonly found across many spoken languages. However, very little research addressed another important aspect prosody: voice quality. In current study, 25 English-speaking mothers from Can...
