This paper reports on a speech production experiment that explores whether the accentual phrase (AP) represents an abstract level of prosodic phrasing in Singapore English. Specifically, it tests whether the right edge of the AP is associated with phrase-final lengthening, the degree of which can be distinguished from lengthening associated with the intonational phrase (IP). Target words were produced in matched sentence contexts in 3 phrasal positions: AP-medial (wordfinal), AP-final, and IP-final. As predicted, target words in AP-final position were longer than those in AP-medial position and shorter than those in IP-final position...

BACKGROUND/AIMS: Evidence from spoken word recognition suggests that for English listeners, distinguishing full versus reduced vowels is important, but discerning stress differences involving the same full vowel (as in mu- from music or museum) is not. In Dutch, in contrast, the latter distinction is important. This difference arises from the relative frequency of unstressed full vowels in the two vocabularies. The goal of this paper is to determine how this difference in the lexicon influences the perception of stressed versus unstressed vowels...

Timing cues are important in many aspects of speech processing, fromidentifying segments to locating word and phrase boundaries. They vary across accents, yet representation and processing of this variation are poorly understood. We investigated whether an accent difference in vowel duration affects lexical segmentation and access. In Glasgow English (GE), /i u e o/ are shorter than in Leeds English (LE), especially for /i u/ before voiced stops and nasals. In a word-spotting experiment, GE and LE participants heard nonsense sequences (e...

BACKGROUND/AIMS: The current study explored the roles of dialect familiarityand social stereotypes in dialect interference effects in a speeded lexical classification task. METHODS: Listeners classified the words bad and bed or had and head produced by local Midland and non-local Northern talkers and the words sod and side or rod and ride produced by non-local, non-stereotyped Northern and nonlocal, stereotyped Southern talkers in single- and mixed-talker blocks...

Phonetic studies of the Korean prevocalic glides have often suggested that they are shorter in duration than those of languages like English, and lack a prolonged steady state. In addition, the formant frequencies of the Korean labiovelar glide are reported to be greatly influenced by the following vowel. In this study the Korean prevocalic palatal glide is investigated vis-à-vis the two phonologically similar configurations of another language - the glide /j/ and the secondary palatalization of Russian, with regard to the inherent duration of the glide component, F2 trajectory, vowel-to-glide coarticulation and glide-to-vowel coarticulation...

BACKGROUND/AIMS: Because the primary articulators for sign languages are the hands, sign phonology and phonetics have focused mainly on them and treated other articulators as passive targets. However, there is abundant research on the role of nonmanual articulators in sign language grammar and prosody. The current study examines how hand and head/body movements are coordinated to realize phonetic targets. METHODS: Kinematic data were collected from 5 deaf American Sign Language (ASL) signers to allow the analysis of movements of the hands, head and body during signing...

This paper reports on the results of two studies investigating the role of allophony in cueing phonemic contrasts. In Cochabamba Quechua, the uvularvelar place distinction is often cued by additional differences in the height of the surrounding vowels. An acoustic study documents the lowering effect of a preceding tautomorphemic or a following heteromorphemic uvular on the high vowels /i u/. A discrimination study finds that vowel height is a significant cue to the velar-uvular place contrast. These findings support a view of contrasts as collections of distinguishing properties, as opposed to oppositions in a single distinctive feature...

BACKGROUND/AIMS: Many studies have shown that experienced second language (L2) learners are more skilled than novice L2 learners at a variety of L2 tasks, including auditory discrimination between members of L2 phonological contrasts. In this paper we argued that while L2 experience is typically beneficial when comparing the effects of more versus less experience, it is not necessarily beneficial when comparing the effects of some experience versus none. METHODS: We compared the perceptual assimilation and discrimination of the Korean sibilant fricatives /s(h)/ and /s*/ by 3 native Mandarin populations: naïve listeners, novice L2 learners (4-6 weeks of experience), and advanced L2 learners (over 2 years of experience)...

BACKGROUND: We investigate the articulatory-acoustic relationship in German fricative sequences. We pursue the possibility that /f/#sibilant and /s#ʃ/ sequences are in principle subject to articulatory overlap in a similar fashion, yet due to independent articulators being involved, there is a significant difference in the acoustic consequences. We also investigate the role of vowel context and stress. METHODS: We recorded electropalatographic and acoustic data from 9 native speakers of German...

In this paper we aim to resolve the phonological status of utterance-initial rises in Spanish wh-questions. METHODS/ANALYSIS 1: In analysis 1 we examine the scaling and alignment properties of utterance-initial rises produced by 14 speakers of Peninsular Spanish. RESULTS/ANALYSIS 1: The results provide evidence for a single bitonal pitch accent at the left periphery (L + <H*) despite multiple options at the right periphery. CONCLUSION/ANALYSIS 1: Our analysis, relying on the notion of sparse tonal specification, helps to explain Sp_ToBI transcribers' past inconsistencies in labeling wh-question initial rises...

This paper investigates similarities between lexical consonant clusters and CVC sequences differing in the presence or absence of a lexical vowel in speech perception and production in two Portuguese varieties. The frequent high vowel deletion in the European variety (EP) and the realization of intervening vocalic elements between lexical clusters in Brazilian Portuguese (BP) may minimize the contrast between lexical clusters and CVC sequences in the two Portuguese varieties. In order to test this hypothesis we present a perception experiment with 72 participants and a physiological analysis of 3-dimensional movement data from 5 EP and 4 BP speakers...

This is a study of final poststressed vowel devoicing following /s/ in Brazilian Portuguese. We contradict the literature describing it as deletion by arguing, first, that the vowel is not deleted, but overlapped and devoiced by the /s/, and, second, that gradient reduction with devoicing may lead to apocope diachronically. The following results support our view: (1) partially devoiced vowels are centralized; (2) centralization is inversely proportional to duration; (3) total devoicing is accompanied by lowering of the /s/ centroid; (4) the /s/ noise seems to be lengthened when the vowel is totally devoiced; (5) aerodynamic tests reveal that lengthened /s/ has a final vowel-like portion, too short to be voiced; (6) lengthened /s/ favors vowel recovery in perceptual tests...

The present study explored the production and perception of the /i/-/I/ vowel contrast in second language (L2)-dominant early learners of American English who no longer fluently speak their first language (L1, Spanish). The production task analyzed the extent to which the early learner group differed from controls (native English speakers and L1-Spanish late-onset learners of English) with regard to duration and spectral centroids. The perception experiment examined how these early learners classified resynthesized stimuli drawn from the /i/-/I/ contrast using distinct acoustic cues - spectral and temporal - in a 2-alternative forced choice identification task...

This paper investigates the production of English unstressed vowels by two groups of early (ESp) and late Spanish (LSp) bilinguals and a control group of native English (NE) monolinguals. Three acoustic measurements were obtained: duration and intensity ratios of unstressed to stressed vowels, normalized vowel formants and euclidean distances. Both groups of bilinguals showed significantly fewer differences in duration between stressed and unstressed vowels than the NE monolinguals. Intensity differences depended on whether the stress pattern of the target English words matched the stress pattern of their Spanish cognates...

The origin and nature of 'irregular', 'sporadic' sound changes have been debated by different theories of phonological change since at least the Neogrammarians. They are often attributed to non-phonological factors, as analogy or borrowing, or to the non-(purely)-phonological mechanism of lexical diffusion. The aim of this paper is to show that an irregular sound change in the historical phonology of Tuscan - namely the voicing of some intervocalic voiceless stops - is not due to borrowing (as often argued), but to a variable and allophonic voicing rule, whose output was only partially subject to phonological recategorization...

The phoneme /ʝ/ in Spanish is known to have a wide range of phonetic realizations, even within a single dialect. Whereas the influence of different contextual factors in conditioning the allophony of /b d ɡ/ has been the object of much recent acoustic investigation, somewhat surprisingly there are no comparable studies of the voiced palatal obstruent. We report on an acoustic investigation of this consonant in Peninsular Spanish. Both preceding context and stress appear to be relevant factors. We also find an effect of style, with more constriction in more formal styles...

Mon is spoken in villages in Thailand and Myanmar. The dialect of Ban Nakhonchum, Thailand, has 2 voice registers, modal and breathy; these phonation types, along with other phonetic properties, distinguish minimal pairs. Four native speakers of this dialect recorded repetitions of 14 randomized words (7 minimal pairs) for acoustic analysis. We used a subset of these pairs in a listening test to verify the perceptual robustness of the register distinction. Acoustic analysis found significant differences in noise component, spectral slope and fundamental frequency...

AIMS: This study investigates the perception and production of the Galician mid vowel contrasts by 54 early Spanish-Galician bilinguals in the cities of Vigo and Santiago (Galicia, Spain). Empirical data is provided to examine the role of language dominance in the perception and production of Galician mid vowel contrasts in order to determine whether the Galician vowel system is becoming more Spanish-like as a result of extensive contact with Spanish in urban areas. METHODS: Perception and production data for each mid vowel contrast were collected in (1) binary forced-choice identification tasks, (2) AX discrimination tasks and (3) a reading-aloud task...
