Marko Liker, Fiona E Gibbon
Although numerous studies have investigated supraglottal strategies for signalling voicing in fricatives, there is still no agreement about the precise characteristics of tongue-to-palate contact timing during voiced as opposed to voiceless fricatives. In this study we use electropalatography (EPG) to investigate articulatory and coarticulatory characteristics of tongue-to-palate contact timing during /s/ and /z/ in English. Five typically speaking participants, speakers of Southern British English, produced 500 trochaic words containing the intervocalic alveolar fricatives /s/ or /z/...

Consonant reduction is often treated as an allophonic process at the phonological planning level, with one production target (allophone) being substituted for another. We propose that, alternatively, reduction can be the result of an online process driven by prosodically conditioned durational variability and an invariant production target. We show that this approach can account for patterns of coronal stop (/t/, /d/, and /n/) production in both American English and Spanish. Contrary to effort-driven theories of reduction, we show that reduction does notdepend on changes to gestural stiffness...

This paper aims to refine our understanding of the speech mechanism and laryngeal features involved in the Korean lenis (/p t k/), aspirated (/ph th kh/), and fortis (/p' t' k'/) plosives. For this purpose we made measurements using a new noninvasive technique called external lighting and sensing photoglottography (ePGG) as well as intra-oral air pressure (Pio) above the glottis, airflow, and acoustic data. From simultaneous recordings of the experimental data, we were ableto quantify the laryngeal-oral coordination of glottal opening and a consonant release, and the covariance of airflow peak and duration of aspiration with glottal opening...

This study examines formant and spectral moment data for the apical and retroflex lateral sounds /l ɭ/ of the Dravidian languages Kannada and Malayalam, together with the rhotic /ɻ/ of Malayalam. Data are presented for 10 male speakers of each language. We find that the first spectral moment is lower for retroflex laterals than for alveolar laterals, and lower for the rhotic /ɻ/ of Malayalam than for the retroflex lateral in the same language. Differences emerge when the retroflex lateral of Kannada is compared with the same sound in Malayalam...

Meghan Clayards
BACKGROUND/AIMS: Previous research found that individual talkers have consistent differences in the production of segments impacting the perception of their speech by others. Speakers also produce multiple acoustic-phonetic cues to phonological contrasts. Less is known about how multiple cues covary within a phonetic category and across talkers. We examined differences in individual talkers across cues and whether token-by-token variability is a result of intrinsic factors or speaking style by examining within-category correlations...

Bei Wang, Yi Xu, Qifan Ding
The current study investigates whether and how focus, phrase boundary and newness can be simultaneously marked in speech prosody in Mandarin Chinese. Homophones were used to construct three syntactic structures that differed only in boundary condition, focus was elicited by preceding questions, while newness of postboundary words was manipulated as whether they had occurred in the previous text. Systematic analysis of F0 and duration showed that (1) duration was a reliable correlate of boundary strength regardless of focus location, while involvement of F0 was only in terms of lowering of phrase-final F0 minima and raising of phrase-initial F0 minima at a relatively strong boundary, (2) postfocus compression (PFC) of F0 was applied across all boundaries, including those with long silent pauses (over 200 ms), and postfocus F0 was lowered to almost the same degree in all boundary conditions, and (3) newness of postfocus words had no systematic effect on F0 or duration...

Phil Howson
Two of the major problems with rhotics are: (1) rhotics, unlike most other classes, are highly resistant to secondary palatalization, and (2) acoustic cues for rhotics as a class have been elusive. This study examines the acoustics of Upper and Lower Sorbian rhotics. Dynamic measures of the F1-F3 and F2-F1 were recorded and compared using SSANOVAs. The results indicate there is a striking delay in achievement of F2 for both the palatalized rhotics, while F2, F1, and F2-F1 are similar for all the rhotics tested here...

Yukiko Sugiyama
Phonological contrasts are typically encoded with multiple acoustic correlates to ensure efficient communication. Studies have shown that such phonetic redundancy is found not only in segmental contrasts, but also in suprasegmental contrasts such as tone. In Japanese, fundamental frequency (F0) is the primary cue for pitch accent. However, little is known about its secondary cues. In the present study, a perception experiment was conducted to examine whether any secondary cues exist for Japanese accent. First, minimal pairs of final-accented and unaccented words were identified using a database, resulting in 14 pairs of words...

Japanese has been observed to have 2 versions of the H tone, the higher of which is associated with an accented mora. However, the distinction of these 2 versions only surfaces in context but not in isolation, leading to a long-standing debate over whether there is 1 H tone or 2. This article reports evidence that the higher version may result from a pre-low raising mechanism rather than being inherently higher. The evidence is based on an analysis of F0 of words that varied in length, accent condition and syllable structure, produced by native speakers of Japanese at 2 speech rates...

Two experiments examined the acoustic correlates of the disyllabic tonal accent contrast in the Trøndersk dialect of Norwegian, and how narrow focus and phrasal position shape the contrast. Production results showed that both tonal accents have a high-low (HL) pitch contour, with different timing. In narrow focus, the pitch contrast was enlarged through asymmetrical F0 changes. When at the right edge of an accent phrase (AP), the accents were shown to have a higher L, lower AP H% tone, shorter stressed vowel, and longer final vowel...

Eriko Atagi, Tessa Bent
BACKGROUND: Accent detection studies have shown native listeners to be highly sensitive to the presence of nonnative accents. This study examined the robustness of this sensitivity. METHODS: We evaluated listeners' accent discrimination performance when presented with a stimulus set consisting of multiple nonnative accents, as well as words and sentences that were unique in each trial. Listeners heard pairs of talkers reading the same word or sentence and indicated whether the talkers' native languages were the same or different...

Daniel Recasens, Clara Rodríguez
BACKGROUND: The study investigates the tongue position and coarticulatory characteristics of a subset of Catalan consonants and vowels using ultrasound. METHOD: Ultrasound data were recorded and analyzed for the Catalan front lingual consonants /t, d, n, l, ɾ, s, r, ʎ, ɲ, ʃ/ and vowels /i, e, a, o, u/ in symmetrical VCV sequences produced by 5 adult Catalan speakers. RESULTS: Among other aspects, data show more tongue body fronting for palatal consonants and, among dentals and alveolars, for laminals than for apicals; the manner of articulation demands account for considerable tongue body retraction and predorsum lowering during the trill /r/ and for some tongue body retraction during /l/ next to front vowels...

This study investigates the acoustic properties of vowels in 2 Modern Greek varieties: Standard Modern Greek (SMG) and Cypriot Greek (CG). Both varieties contain in their phonetic inventories the same 5 vowels. Forty-five female speakers between 19 and 29 years old participated in this study: 20 SMG speakers and 25 CG speakers, born and raised in Athens and Nicosia, respectively. Stimuli consisted of a set of nonsense CVCV and VCV words, each containing 1 of the 5 Greek vowels in stressed and unstressed position...

Adam J Chong, James Sneed German
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...

Natasha Warner, Anne Cutler
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...
