Showing papers in "Journal of Phonetics in 2015"

TL;DR: It is suggested that reliance on multiple cues in representation of a phonetic contrast can form the basis for distinct individual cue-weighting strategies in phonetic categorization.

TL;DR: It is argued that earlier claims that intonation is not necessary for correct turn-end projection are misguided, and that research on turn-taking should continue to considerintonation as a source of turn- end cues along with other linguistic and communicative phenomena.

TL;DR: The results showed a significant co-dependency between onset f0 and VOT across phonological voicing categories but not within categories, in both languages, highlighting the importance of phonological factor in determining the pattern of covariation.

TL;DR: The research papers in the present Special Issue in Journal of Phonetics provide further evidence for the style-dependency of speech data and hence, on the theories and models and show that some results remain stable independently of the speaking style under investigation.

TL;DR: This paper presents a methodology based on Functional Data Analysis (FDA) that allows the investigator to delegate most of the decisions involved in the quantitative description of multidimensional time series to the data themselves and produces a data-driven parametrisation of the main shape traits present in the data that is visually interpretable, in the same way as slopes or peak heights are.

TL;DR: It is speculated that the synchronic oral articulation of NMF nasal vowels may have arisen—at least in part—due to misperception of the articulatory source of changes in F1 and F2, rather than to mere chance, as has been argued.

TL;DR: This paper introduces a model of the cognitive architecture of a communicating agent, called COSMO (for “Communicating about Objects using Sensory–Motor Operations') that allows a probabilistic expression of the main theoretical trends found in the speech production and perception literature, which enables a computational comparison of these theoretical trends.

TL;DR: The authors explored the temporal organization of six regional dialects of American English to gain a better understanding of the perceptual impressions of speaking rate variation, and found that Southern American English is characterized by a slow overall articulation rate, long pauses, and highly variable syllable-to-syllable vowel durations, whereas the New England dialect is characterised by a fast overall articulating rate, short pauses and extremely variable consonant durations.

TL;DR: This article found that English and Spanish VOT were shorter at code-switching points than in comparable monolingual utterances, and that the effect applies in the natural speech of early bilinguals.

TL;DR: Results show spontaneous speech to contain shorter vowel durations and stronger effects of contextual assimilation than elicited speech, and robust acoustic differences between vowels in spontaneous speech, maintaining the overall vowel space pattern.

TL;DR: Results indicated that learners who received perceptual training on palatal codas outperformed those who did not in perception and production tasks and generalized learning to new words and new talkers, providing evidence that L2 perception andProduction systems are linked.

TL;DR: It is concluded that speech situation affects the occurrence of reduced word pronunciation variants, which should be accounted for by psycholinguistic models of speech production and comprehension.

TL;DR: Overall the study suggested that read and spontaneous speech can be recognized based on very subtle cues to these speaking styles.

TL;DR: Results showed that Swiss speakers articulate at a lower syllable rate than French speakers and Belgian speakers, independently of the speaking style (reading or conversation).

TL;DR: The role of imitation in modern speech and language is outlined, the evidence provided by experimental and modeling studies for the potential role of simulation in the emergence and evolution of phonological systems are reviewed, and how the resulting hypotheses could be tested in the framework provided by the multi-agent computational COSMO model is discussed.

TL;DR: The findings suggest that prosodic and visual information work in a complementary fashion and are not integrated in the same way as auditory andVisual information during segmental perception.

TL;DR: It is argued that reading intonation is not comparable tointonation in spontaneous speech, and that this has important consequences also for the choice of methodology in child language acquisition research.

TL;DR: Two experiments aimed at elucidating the structure of individual differences in non-native speech perception and the relationship between these abilities, phonological short term memory, and early second language word learning indicate that phonologicalshort term memory and discrimination ability both predict word learning accuracy and that discrimination ability does so in a mostly feature-specific manner.

TL;DR: The longitudinal results showed that some learners were unable to produce the Korean contrast in a native-like way even after one year of intensive L2 instruction, suggesting that the learning of an L2 contrast may not always be predicted by cross-language acoustic correspondences.

TL;DR: Overall, schema representations connect usage-based theories of language to the action of speaking, and give rise to assumptions about the primacy of certain linguistic forms in the production process.

TL;DR: An analysis of the fitted values of models of F1 and F2 based on consonantal factors shows that the formant values predicted by those models separate vowels in “easy” and “hard” words in the manner observed in W2004, and discusses the implications for the effect of phonological neighbourhood density on language production.

TL;DR: This work argues that the child can solve the correspondence problem for speech sounds by imitation through the mirroring behaviour of his caregivers within imitative interactions and that this mechanism is more consistent with the developmental data.

TL;DR: A functional and cross-language perspective on the organization of phonological systems based on the notion of functional load (FL) is proposed and a strong preference toward consonant-based distinctions rather than vowel- based distinctions in a reduced (lemmatized) configuration of the lexicon is reflected.

TL;DR: The results suggest that although f0 declination occurs in many languages, it might not have a purely physiological origin in breathing, but rather reflects cognitive processing which allows speakers to look ahead when planning their utterances.

TL;DR: This work investigates the relationship between speech production and perception when acoustic attributes change naturally in response to the demands of speech communication, and presents models and analyses with sufficient detail to simulate these effects.

TL;DR: It is concluded that the sound change in lexical pitch accent is in progress by satisfying the prosodic properties of both Seoul and South Kyungsang Korean.

TL;DR: The P300 and beta band results suggest that attention modulation mechanisms are triggered when listeners are exposed to sudden rises in spoken F0, and there was a lack of attention orientation response when non-speech F0 changes were presented, or when subjects were exposed to lowering of F0 in speech.

TL;DR: It is found that listeners can distinguish between self-identified gay and heterosexual male speakers of American English upon hearing word-length stimuli and evidence that listeners' judgments improved if they were presented with multiple phonemes, such as a vowel and /s/.

TL;DR: These findings suggest that Mandarin speakers have more robust pitch control over self-produced vocalizations and are thus less affected by auditory feedback perturbations.

TL;DR: The results show clear differences in formant dynamics between identical twins, and the differences were large enough to discriminate them using Discriminant Analysis.
