TL;DR: A comparative evaluation of metrics for the quantification of speech rhythm, comparing pairwise variability indices and interval measures together with rate-normalised interval measures, with VarcoV offering the most discriminative analysis and %V suggesting insights into the process of accommodation to second language rhythm.

TL;DR: The results suggest that the mechanism of boundary-related lengthening is more complex than current models propose and cannot be explained without reference to the location of main lexical stress and appears to involve more than one stretch of speech, at least in American English.

TL;DR: How speakers may strengthen domain-initial segments during production and how listeners may use the resulting acoustic correlates of prosodic strengthening during word recognition are discussed.

TL;DR: Two experiments examining the effect of prosodic structure and phrase length on pause duration showed a significant post-boundary effect of Prosodic branching and significant pre- and post- boundary phrase length effects.

TL;DR: Measurements related to average f0 level and f0 change over eight consecutive sections of the whole vocalic segment, for their roles as both acoustic and perceptual correlates of Cantonese lexical tones, correspond well with description of tones based on Wang's phonological features.

TL;DR: The results obtained with the free classification task in the current study provided further evidence that the underlying structure of perceptual dialect category representations reflects important linguistic and sociolinguistic factors.

TL;DR: Parts of this study were presented at the ESF International Conference on Tone and Intonation (Santorini, September 2004) and at talks at the Laboratoire de Parole et Langage (Aix-en-Provence, April 2005) and Institut de la Communication Parle´e (Grenoble, November 2005).

TL;DR: Investigation of VOT, f0, closure duration, burst amplitude and spectral characteristics provide evidence for a primary effect of accent (a level of phrasal prominence) on these measures as cues to stop voicing and/or place of articulation.

TL;DR: The present study aims at providing a realistic and robust estimate of the JND for tempo in speech, by using multiple speech tokens from multiple speakers, yielding an estimatedJND for speech tempo of about 5%.

TL;DR: It is argued that the phonetic degree of tongue body horizontal position correlates with the phonological alternation in suffixes and a plausible phonetic basis for transparency can be found in quantal characteristics of the relation between articulation and acoustics of transparent vowels.

TL;DR: It is suggested that there may be more than one manner in which talker-specific information influences perception, and familiarity with a voice only helps listeners when that voice is the one being attended.

TL;DR: Swedish nonsense syllables /gig/, /gyg/, /geg/ and /gog/, produced by four speakers were video-recorded and presented to male and female subjects in auditory, visual and audiovisual mode.

TL;DR: In most cases authors are permitted to post their version of the article (e.g. in Word or Tex form) to their personal website or institutional repository.

TL;DR: It is concluded that Japanese voiceless stops have an intermediate degree of aspiration and constitute an exception to the short lag and long lag dichotomy of voiceless stop said to characterize many languages.

TL;DR: Perceptual tests show that achieving focalization results in a lower intelligibility for the children than for the adults, and simulations using an articulatory model demonstrate that the realization of the focalization feature may require different articulatory gestures for young children compared to adults.

TL;DR: Results show that Guttural vowels exhibit a range of marked (non-modal) acoustic voice quality attributes, and vowels following guttural consonants exhibit the same range of voice quality Attributes through gutturally co-articulation.

TL;DR: The results suggest that infants are sensitive to the voicing categories of the ambient language but that they may be able to control prevoicing more successfully than aspiration.

TL;DR: It is argued that the two phenomena may be treated under a unified account of intraspeaker variability that builds upon the sociolinguistic concept of Audience Design.

TL;DR: Findings suggest that phonotactic restrictions constrain phonetic processes in prosody, sandhi processes, and phonotactics, yielding systematic phonetic cues to prosodic structure and phonological distinctions.

TL;DR: Results on accent distribution in these elicited data reveal that different contrast relations have a significant impact in the Dutch utterances, and in Romanian, accent distribution seems to serve a demarcative rather than a contrastive function.

TL;DR: It is shown that an account of these results under autosegmental-metrical theory requires positing additional constraints in phonetic models of f0, which assumes additional constraints on relative tone heights and strictly monotonic interpolation between tones.

TL;DR: In Finnish, a full-fledged quantity language, segment durations are adjusted to achieve a temporally and tonally uniform realization of accent, contrary to the situation in many nonquantity languages, in which the temporal realized of accent varies as a function of the segmental structure of the accented syllable.

TL;DR: The results suggest that vowel production features, properly constrained by PCA modeling, can be mapped with sufficient accuracy from easily measured cepstrum parameters.

TL;DR: A statistical articulatory–acoustic model integrating the non-linear growth of the human vocal tract was used to describe infant behavior before and at the beginning of canonical babbling, and a portrait largely consistent with previously reported experimental data is provided.

TL;DR: Evidence is reported for a need to reconsider the temporal interval of a segment as the time period during which the target of the segment is being approached, where the target is the optimal form of the segments in terms of articulatory state and/or acoustic correlates.

TL;DR: It is suggested that a high F2 for /u/ may lead to perceptual confusion with the front rounded vowel /y/, which is also present in the French phoneme Inventory, and suggests that the structure of a language's phoneme inventory has important effects on the articulatory strategies adopted by its speakers.

TL;DR: The use of the contour inventory for measuring intonational development as a supplement to more traditionally utilized measures (e.g., accent range) is supported.

TL;DR: The method is illustrated by the calculation of the sound source when a vortex is swept past an obstruction in the vocal tract and the differences between the pressure sources of sibilant fricative production and of voicing and aspiration are discussed.
