Closure duration of stop consonants
Journal of Phonetics, 1983Abstract: The present research was designed to provide additional data on stop closure durations as a function of (1) voicing, (2) stress, (3) position, and (4) place-of-articulation. Six subjects, three males and three females, produced a series of nonsense disyllables of the form CVCVC in a carrier phrase.

Transglottal airflow during stop consonant production
The Journal of the Acoustical Society of America, 1973The possibility that velopharyngeal opening may cause the transglottal pressure drop necessary for the production of normal English non-nasal voiced stop consonants was investigated. Nasal airflow rate and intraoral pressure were measured during the production of a selected speech sample, produced by three normal adult females.

Pattern Playback revisited: Unvoiced stop consonant perception
The Journal of the Acoustical Society of America, 2005Among the most influential publications in speech perception is Liberman, Delattre, and Cooper’s [Am. J. Phys. 65, 497–516 (1952)] report on the identification of synthetic, voiceless stops generated by the Pattern Playback. Their map of stop consonant identification shows a highly complex relationship between acoustics and perception.

Acoustic Properties of Stop Consonants
The Journal of the Acoustical Society of America, 1957The two major cues for stop consonants, the burst of the stop release and the formant transitions in the adjacent vowel, were investigated. Detailed energy density spectra of the bursts were prepared. The transitions were studied by means of sonagrams. Possible criteria for identification were developed and tested.

Stop consonant discrimination based on human audition
The Journal of the Acoustical Society of America, 1979A system for discrimination of stop consonants has been designed on the basis of studies of auditory physiology and psychophysics. The system consists of a one-third octave filter bank as an approximation to auditory tuning curves, a bank of high speed, wide dynamic range envelope detectors, a logarithmic amplifier, and a digital computer for analysis ...

Spectral tilt change in stop consonant perception
The Journal of the Acoustical Society of America, 2008There exists no clear understanding of the importance of spectral tilt for perception of stop consonants. It is hypothesized that spectral tilt may be particularly salient when formant patterns are ambiguous or degraded. Here, it is demonstrated that relative change in spectral tilt over time, not absolute tilt, significantly influences perception of ...

Simplification of /s/ + Stop Consonant Clusters
Journal of Speech, Language, and Hearing Research, 1984This longitudinal study examined individual patterns and changes in /s/ + stop cluster simplifications of six normally developing children. Subjects produced selected words containing initial voiced and voiceless stops and /s/+ stop clusters at monthly intervals.

Some Characteristics of Stop Consonants
The Journal of the Acoustical Society of America, 1959Stop-vowel syllables were synthesized by use of both the cascaded resonant circuit (POVO) and the dynamical vocal tract analog (DAVO). Variation of formant positions or of articulatory configurations, intensity envelope, and inflection of fundamental frequency were controlled. A noise source was used as excitation for unvoiced stop consonants. Unvoiced

Arabic Stop Consonant Acoustic Characterization
2019The present study investigates Arabic stop consonants. Our goal is to give sufficient acoustic cues for detecting and characterizing such consonants. In general, speech is made with sequences of consonants (fricatives, nasals and stops), vowels and glides. The first task is then to separate stop consonants from other phonemes. From an acoustic point of

Acoustic invariance for stop consonants
The Journal of the Acoustical Society of America, 1974Acoustic invariance for the six stop consonants occurring with /i/, /a/, and /u/ in naturally spoken CV syllables was investigated. Each syllable was divided into consonant and vowel fragments that were identified in isolation in Experiment I. Consonant fragments that were long enough to be identified as consonants, rather than noise, yet short enough ...
