TL;DR: The present experiment demonstrated that analogous spectral manipulations applied to the members of TOT and NOT continua do not result in systematic shifts in the location of the simultaneity-successivity threshold, suggesting that the role of F1 in the perception of voicing does not have a purely auditory basis.
Abstract: Untrained listeners can reliably judge the temporal order of the onsets of (a) pairs of coterminous tones [forming tone‐onset‐time (TOT) continua], and (b) higher‐frequency bandlimited noises and lower‐frequency bandlimited pulse trains [forming noise‐onset‐time (NOT) continua], but only if the onset of the second sound lags the first by at least 15–20 ms. It has been argued that the limitation of auditory temporal‐order resolution that gives rise to this threshold also underlies the distinction between voiced [b,d,g] and voiceless aspirated (ph,th,kh] syllable‐initial stop consonants [which can be expressed in differences of voice‐onset‐time (VOT)]. The positions of boundaries between phonetic categories on VOT continua depend on the values of a variety of spectral parameters, including the onset frequency of the first formant; lowering this results in boundaries shifting to longer values of VOT. The present experiment demonstrated that analogous spectral manipulations applied to the members of TOT and N...

TL;DR: The production and perception of contrastively laryngealized vowels in Coatzospan Mixtec (CM), an Otomanguean language of southern Mexico, are examined to add to knowledge of the phonetics of an underdescribed and endangered language and provide a more finely grained notion of the array of acoustic cues that implement the categorical, contrastive phonological property of vowels.

TL;DR: Results suggest that temporal ratios between oral and laryngeal gestures tend to remain constant across changes in stress and speaking rate, consistent with those obtained for other aspects of speech motor control as well as for other types of human motor behavior, suggesting common modes of control.

TL;DR: A statistically guided, knowledge-based, acoustic-phonetic system for the automatic classification of stops, in speaker independent continuous speech, is proposed that uses a new auditory-based front-end processing and incorporates new algorithms for the extraction and manipulation of the acoustic- phonetic features that proved to be rich in their information content.
Abstract: In this paper, the acoustic-phonetic characteristics of the American English stop consonants are investigated. Features studied in the literature are evaluated for their information content and new features are proposed. A statistically guided, knowledge-based, acoustic-phonetic system for the automatic classification of stops, in speaker independent continuous speech, is proposed. The system uses a new auditory-based front-end processing and incorporates new algorithms for the extraction and manipulation of the acoustic-phonetic features that proved to be rich in their information content. Recognition experiments are performed using hard decision algorithms on stops extracted from the TIMIT database continuous speech of 60 speakers (not used in the design process) from seven different dialects of American English. An accuracy of 96% is obtained for voicing detection, 90% for place of articulation detection and 86% for the overall classification of stops.

TL;DR: In this article, the authors investigated laryngeal and supralarygeal correlates of the voicing contrast in alveolar obstruent production in German and found that the presence/absence of glottal opening is not a consistent correlate of the voiced contrast in German.
Abstract: This work investigates laryngeal and supralaryngeal correlates of the voicing
contrast in alveolar obstruent production in German. It further studies laryngealoral
co-ordination observed for such productions. Three different positions of
the obstruents are taken into account: the stressed, syllable initial position, the
post-stressed intervocalic position, and the post-stressed word final position. For
the latter the phonological rule of final devoicing applies in German. The
different positions are chosen in order to study the following hypotheses:
1. The presence/absence of glottal opening is not a consistent correlate of the
voicing contrast in German.
2. Supralaryngeal correlates are also involved in the contrast.
3. Supralaryngeal correlates can compensate for the lack of distinction in laryngeal
adjustment.
Including the word final position is motivated by the question whether neutralisation
in word final position would be complete or whether some articulatory
residue of the contrast can be found.
Two experiments are carried out. The first experiment investigates glottal abduction
in co-ordination with tongue-palate contact patterns by means of simultaneous
recordings of transillumination, fiberoptic films and Electropalatography
(EPG). The second experiment focuses on supralaryngeal correlates of
alveolar stops studied by means of Electromagnetic Articulography (EMA)
simultaneously with EPG. Three German native speakers participated in both
recordings. Results of this study provide evidence that the first hypothesis holds
true for alveolar stops when different positions are taken into account. In
fricative production it is also confirmed since voiceless and voiced fricatives are
most of the time realised with glottal abduction. Additionally, supralaryngeal
correlates are involved in the voicing contrast under two perspectives. First,
laryngeal and supralaryngeal movements are well synchronised in voiceless
obstruent production, particularly in the stressed position. Second, supralaryngeal
correlates occur especially in the post-stressed intervocalic position. Results
are discussed with respect to the phonetics-phonology interface, to the role of
timing and its possible control, to the interarticulatory co-ordination, and to
stress as ‘localised hyperarticulation’.
