The Effects of Fundamental Frequency Level on Voice Onset Time in Normal Adult Male Speakers

Abstract

The purpose of this study was to examine the effect of fundamental frequency (F(0)) on stop consonant voice onset time (VOT). VOT was measured from the recordings of 56 young men reading phrases containing all 6 English voiced and voiceless stops in word-initial position across high-, medium-, and low-F(0) levels. Separate analyses of variance for the voiced and voiceless stops revealed no significant main effect for F(0) for the voiced stops but a significant F(0) effect for the voiceless stops. Across the voiceless stops, productions at high F(0)s displayed significantly shorter VOTs than productions at low or mid F(0)s. The findings indicated that researchers must take into account the F(0) level at which voiceless stop VOT is measured.

Voice Onset Time for Turkish Stop Consonants in Adult Cochlear Implanted Patients

“…It is measured from the onset of the energy 'burst' corresponding to the release of an articulatory constriction to the first of the regularly spaced vertical striations of the vocal fold vibrations [4]. VOT has been used to examine the articulatory differences across languages, genders, and motor speech impairments [5]. The control of acoustic cues to voicing requires a critically timed coordination of respiratory, phonatory and articulatory movements, so it presents a particularly challenging contrast for acquisition and for experimental analysis [1].…”

“…Factors that can effect the magnitude of VOT include physiological differences (such as age, lung volume, vocal fold tension), pathological status (hearing impairment, depression), and different linguistic tasks (speech task, speech rate, phoneme environment [4,5].…”

Evaluation of the articulatory characteristics of voice in cochlear implanted children

“…[2] VOT is effected by some factors including physiological differences (age, gender, lung volume, vocal fold tension), pathological diseases (hearing loss, depression) and different linguistic status (speech task, speech rate, phoneme environment). [4,5] VOT values are different between languages because of their differences in structure due to originating from different language families. [4,7] There are few studies which reported about VOT in cochlear implant users.…”

“…[2] Hearing loss is a feature which can affect the significance of VOT. [4,5] Since VOT is a useful method for documenting the articulatory-phonatory aspects during the speech, we investigated and compared VOT values for Turkish stop consonants in healthy children and children with cochlear implant (CI) to clarify the effect of CI and sequential hearing rehabilitation over VOT values.…”

“…Apesar da diversidade de possibilidades de aplicação da análise vocal digital, pode ser observada na literatura uma tendência de se investigar parâ-metros acústicos em uma população predominantemente adulta [5][6][7][8][9][10][11][12] . A população infantil é pesquisada de forma mais restrita.…”
