This study investigated acoustic properties of the four-way contrast in Russian voiceless sibilant fricatives (/ssj ʂ ʃj/). Words with these consonants, occurring in a variety of phonetic contexts, were elicited from 10 Russian native speakers. Measurements were made of duration, centre of gravity (COG) and intensity of fricative noise, as well as of formants F1–F3 during the following vowel. The results revealed that the anterior vs. posterior contrast was clearly distinguished by COG throughout the frication period, and to a lesser degree by noise intensity. The palatalized vs. non-palatalized contrast was distinguished by F1 and (especially) F2 at the onset, the midpoint, and, in some cases, at the offset of the following vowel. The four-way contrast was thus well categorized by a combination of COG and F2–F1 differences. Fricative duration only marginally distinguished /ʃj/, commonly described as geminate, from the other consonants. Clear durational differences, however, were observed for the same consonants in different positional and stress contexts. Overall, the results of the study provide a systematic documentation of the typologically uncommon fricative contrast, while also shedding light on some facts of synchronic patterning and historical development of the fricative system of Russian.

Jamaican Creole is one of the major Atlantic English-lexifier creoles spoken in the Caribbean. In Jamaica, this creole is popularly labelled as ‘Patwa’ (Devonish & Harry 2004: 441). There is a widely-held view in Jamaica that a post-creole continuum exists. The continuum is between Jamaican English and Jamaican Creole (Meade 2001: 19). Many scholars holding this view find it necessary to distinguish among acrolectal, mesolectal and basilectal varieties (Irvine 1994, Beckford-Wassink 1999, Patrick 1999, Meade 2001, among others). Major phonological differences are found between the two extremes. However, a discussion of the phonological differences in the continuum and problems with the theoretical notion of a ‘post-creole continuum’ is beyond the scope of this paper. The aim of this paper is to provide an adequate description of some salient aspects of the synchronic phonetics and phonology of Jamaican Creole based on the speech forms of two native Jamaican Creole speakers, Stacy-Ann Watt, a post-graduate female student at the University of West Indies, Mona, and Racquel Sims, 22 year old female from the parish of St Catherine. Both come from the Eastern parishes of the island.

This paper investigates the relevance of three prosodic parameters (alignment, duration and scaling) in the conveyance of contrastive focus in Catalan, Italian and Spanish. In particular, we seek to determine how the Effort Code is instantiated in the expression of contrastive focus in both production and perception. According to the Effort Code, putting more effort into speech production will lead to greater articulatory precision (de Jong 1995, Gussenhoven 2004) and this is related to the expression of focus in the sense that wider pitch excursions will be used to signal meanings that are relevant from an informational point of view. A dual production and perception experiment based on an identification task was conducted. Results for the production part show that contrastive focus accents have earlier peaks for all three languages but f0 peaks are systematically lower only in Italian. Syllables bearing the contrastive focus accents are also longer in the three languages. Regarding the results for the perception part, converging evidence is found not only for an active perceptual use of the three prosodic parameters present in production but also for language-specific preferences for particular prosodic parameters.

The present study examines the effect of two potential catalysts for interlanguage phonetic interaction, code-switching and language mode, on the production of voice onset time (VOT) to better understand the role of (near) simultaneous dual language activation on phonetic production, as well as the nature of phonetic transfer. An oral production paradigm was carried out in which Spanish–English bilinguals produced words with initial voiceless stops as non-switched tokens, code-switched tokens in an otherwise monolingual context, and code-switched tokens in a bilingual context. Results demonstrated a degree of phonetic transfer associated with code-switching, either unidirectional or bi-directional. Specifically, English, with long lag VOT, was more susceptible to phonetic transfer than Spanish (short lag). Contrary to expectations, while the code-switching effect was present in both monolingual and bilingual mode, there was no additional transfer, or additive effect, of bilingual language mode. Differences in the effects of code-switching on English and Spanish are discussed with respect to the inherently different acceptable VOT ranges in the two languages. Furthermore, the lack of difference in VOT between the code-switched tokens in the monolingual and bilingual contexts is taken to suggest limits on phonetic transfer.

This paper presents impressionistic, electroglottographic and acoustic data exploring the distribution of glottalic and pulmonic airstream in word-final Scottish English obstruents. We explore the relationship between these airstream mechanisms and aspirated or glottalised phonatory settings of individual speakers near this obstruent locus. We address the hypothesis that the tendency for pre-stop glottalisation found in some British English varieties can explain the occurrence of glottalically-released stops. This hypothesis suggests that ejectives would appear as an occasional artefact of mistimed glottalisation. We also investigate whether a glottalic airstream acts as a potential contrast enhancement mechanism, through association with /−voice/ as opposed to /+voice/ stops. We show that glottalisation and aspiration can readily co-occur in the same speaker, and that local phonatory setting (with glottalised or aspirated articulation) can be consistently used as a secondary correlate of obstruent /−voice/, in the context of stops and fricatives respectively. The results show that although glottalisation as a secondary correlate of /−voice/ stops often co-occurs with an ejective release, they are not necessarily bound together. These results argue against a simple epiphenomenal explanation for the appearance of ejective stops in English, while also showing that they are not (yet) a systematic phonological enhancement in this variety.

Previous research has indicated that the H (high) of a nuclear accent may be realized as a flat stretch of contour rather than as a single turning point. Both the duration of this plateau and its alignment within the accented syllable are affected by the segmental and prosodic structure of the utterance. The present work investigates whether a non-structural variable, namely pitch span, also affects the realization of the plateau. Speakers replicated all-sonorant utterances in different pitch spans. Results show that both the duration and alignment of the plateau vary with pitch span but in ways different from the way they vary with prosodic structure. Importantly, results also indicate that, when using a proportional measure of alignment, the end of the plateau is anchored within the syllable for each speaker and may be a marker of linguistic structure.

Linguopalatal and sagittal vocal tract configuration data from a large number of languages reveal that the so-called palatal consonants (i.e. [ç ʎ c ɲ j]), as well as the vowel [i], are often realized simultaneously at the alveolar and palatal zones. Moreover, while some of these sound categories may also exhibit a palatal constriction ([ç c ɲ j i]), others are exclusively alveolar or alveolopalatal in line with the manner of articulation characteristics involved ([ʎ], also [ɕ] and [tʃ]). Consonants may favor one or more places of articulation and differ in fronting degree depending on the language taken into consideration; moreover, there appears to be a symmetry requirement by which consonants differing in manner, such as [c] and [ɲ], may agree in place. The data reported in this paper argue in favor of a revision of the articulatory classification of palatal consonants by the International Phonetic Alphabet involving their subdivision into two classes, an alveolopalatal and a palatal one.

Itunyoso Trique /itunˈjoso ˈtɾiki/ is an Oto-Manguean language (Mixtecan branch) spoken in the town of San Martín Itunyoso, Oaxaca, Mexico. It is one of three Trique languages, all of which are spoken in Oaxaca, Mexico. According to the 2005 census (INEGI 2005), there are 1,345 inhabitants in the town, virtually all of whom speak Itunyoso Trique as a native language. However, this number does not reflect the total number of speakers, as approximately 30%–50% of the population lives outside of San Martín Itunyoso at any given time. The population of the nearby town of Concepción Itunyoso, with a population of 261 (ibid.), is considered to speak the same dialect. The remaining populations of speakers are found in Oaxaca City, Mexico City, and the United States.

There are many unsolved problems concerning the linguistic interpretation of intonation curves obtained instrumentally. Among the major ones are (1) How accurate must the instrumental data be to make sure that no linguistically relevant information is missed? (2) Which of the details of the intonation curve are linguistically relevant? (3) How should the graph be scaled? (4) How should the curves be normalized so as to neutralize individual (speaker-dependent) differences?

Theoretical and descriptive work on Spanish phonetics and phonology has been largely based on Peninsular varieties. This study uses electropalatography (EPG) to investigate articulatory characteristics of coronal consonant contrasts in Argentine and Cuban Spanish. Simultaneous EPG and acoustic data were collected from five speakers from Buenos Aires (Argentina) and three speakers from Havana (Cuba) reading sentences with various syllable-initial coronal consonants corresponding to the orthographic 〈t, ch, n, ñ, s, z, ll, y, l, r〉. As a control, the same data were collected from a single speaker of Peninsular Spanish from Madrid. As expected, the main distinction in both varieties was made between anterior and posterior coronal consonants ((denti-)alveolars vs. (alveolo-)palatals) and reflected the historical merger of the sounds represented by 〈s–z〉 and 〈ll–y〉. At the same time, the results revealed some consistent differences between the two varieties in the location of the constriction and the amount of linguopalatal contact for most coronal consonants. First, the coronal consonants produced by the Argentine speakers were overall considerably more fronted and more constricted than the corresponding consonants produced by the Cuban speakers. Second, 〈ll, y〉 were produced as a fronted alveolo-palatal fricative by the Argentine speakers, and as an approximant by the Cuban speakers. Inter-speaker variation was observed within the varieties in the articulation of some consonants, namely in the Argentine alveolo-palatal fricative and nasal (〈ll, y〉 and 〈ñ〉), and the Cuban alveolo-palatal affricate 〈ch〉.

The Slavic affricate represented by /č/ is tacitly or explicitly assumed to be // for all Slavic languages. In this paper we revise the affricate inventories of Polish and Czech, showing that the symbol /č/ stands for two different sounds: the palatoalveolar // in Czech and the retroflex // in Polish. This conclusion is supported by acoustic results for Polish and Czech data. The fact that COG (centre of gravity) values of frication are not significantly different for Polish and Czech /č/ appears a bit surprising especially in light of the fact that COG is generally seen as a parameter contributing to the distinction of fricatives (including sibilants, see e.g. Gordon, Barthmaier & Sands 2002). Our results show that other parameters such as duration of the frication phase, F1 and F2 of the following vowel as well as spectral slopes are more reliable cues for distinguishing the small differences between affricates examined here.

Hakka Chinese is also known in China as Kejia dialect. The present study is based on phonetic data collected from native speakers of Hakka Chinese, male and female, aged between 18 and 22, during our field trips to Hakka-speaking Meixian County in the northeastern part of Guangdong Province in southeastern China in 2007. The speakers have lived all their life in Meijiang District of the county, speaking Meijiang variety which is considered representative of Meixian Hakka. The style of speech illustrated here is that typical of the educated younger generation and the recording is that of a 22-year-old male college student.

Prenasalized stops, that is, homorganic nasal+stop elements that behave as single phonological segments, raise a number of interesting questions concerning the relationship between phonological units and timing in speech. Do complex phonetic elements of this kind occupy the same duration as simpler elements, such as plain stops or nasals? Do prenasalized stops have the same timing pattern as a phonological sequence of nasal plus stop? How do prenasalized stops act with respect to rules which adjust the duration of neighboring segments? For example, would a vowel before a prenasalized stop be shortened by the widespread rule which shortens a vowel in a closed syllable (Maddieson 1985)? It has been argued that the status of prenasalized stops as single segments is directly related to their duration. They have been defined as nasal+stop sequences with the duration typical of other single segments (Herbert 1986). He, and Sagey (1986), in her dissertation on complex segments, both indicate that they would expect phonological consonant sequences to have longer durations than single segments regardless of whether the single segments are phonetically simple or complex. On the other hand, Ladefoged and Maddieson (1986) suggest that there is no demonstrated phonetic difference in timing between nasal+stop sequences and prenasalized stops. Purported language-internal contrasts between these elements actually involve a difference between geminate and single nasals before stops (as in Sinhalese), or between syllabic and non-syllabic nasals before stops. They suggest that deciding if a nasal+stop element is a prenasalized stop is not a phonetic issue but one which concerns solely the phonology of the language in question.

This paper is intended to provide a general orientation regarding the articulatory phonetics of the languages involved in the SAM project, as described in Wells (1987): it comprises a brief statement of the phonemic system of each language (the consonants and vowels, and how they are transcribed), together with notes on the most salient realizational and suprasegmental characteristics. As in Wells (1987), the objective is to assign a computer-coded phonemic notation, referred to as SAM-PA, using only the printable symbols from the 7-bit ASCII series.

While the history of interest in voice quality dates back at least as far as Henry Sweet (e.g. 1890), there was for many years little agreement on how to classify voice quality or how to transcribe it as part of a phonetic transcription. Indeed, there is not even agreement on precisely what the term covers in that it is often restricted to aspects of voice quality derived from vocal fold activity, rather than the fuller meaning which encompasses features derived from supralaryngeal settings of the articulators. Authors such as Nolan (1983) have used the phrase long-term quality as an alternative; however, in this article we will retain the traditional term but with a wide application to account for voice quality derived from airflow features, vocal fold activity, and supralaryngeal activity.

A poll of BrE pronunciation preferences was carried out in late 1998, based on a self-selected sample of nearly 2000 ‘speech-conscious’ respondents, who answered a hundred questions about words of uncertain or controversial pronunciation. The findings allow us to answer questions about lexical incidence and sound changes in progress. (This is a revised and considerably extended version of the report published as Wells 1999.)

This paper investigates whether or not there are phonetic correlates of prominence at the word level in Tamil that can be associated with word-initial stress. There is no lexically distinctive stress but there are indications in previous work – based on impressionistic judgements and experimental evidence of vowel reduction patterns – that word-initial syllables may be prominent. Sets of words containing segmentally identical syllables in different positions within the word, e.g. [nariku], [kanavu] and [w o:dina] were recorded by five speakers in a carrier phrase. The prosodic properties of the test syllables were compared to establish whether syllable position had a significant effect. No consistent results were found for either duration or loudness: their role at the word level in Tamil seems to be confined to marking intrinsic segmental and quantitative distinctions. Significant differences in F0 related to syllable position would be consistent with initial syllables bearing abstract word-level prominence. This would be marked primarily through the association of phrasal pitch accents, unaccompanied by independent differences of loudness or robust durational effects.

There is no standard phonetically balanced short passage for Portuguese research and clinical practice. This paper presents results of a novel analysis of ‘The North Wind and the Sun’ (NWS) passage that aims to determine if it is phonetically balanced for European Portuguese (EP) and Brazilian Portuguese (BP), based on new transcriptions resulting from algorithms developed for grapheme–phone transcription in these two varieties of Portuguese. These algorithms (based on standard EP and São Paulo BP varieties) are the same as those used to collect the frequency data, which is central to determining if a text is phonetically balanced. Results showed that neither transcription violates phonotactic rules, i.e. permissible combinations of speech sounds. The NWS is not phonetically balanced for BP if the phonemes are considered individually but is evenly distributed in terms of manner of articulation. The EP version of the NWS passage is a phonetically balanced text for EP.

Words in fluent speech frequently differ from their citation forms. This paper investigates some factors influencing the realization of the preposition for and the number four. Realizations of these words in read and spontaneous speech show that instead of viewing function words as having discrete weak, strong, or even intermediate allomorphs, a continuum resulting from gestural interaction better represents the facts. In the speech examined here, numerous factors influence different aspects of the realization of for and four. The duration of the onset /f/ is affected by the preceding prosodic boundary while the duration and composition of the rime is affected by foot structure and segmental content. The preposition exhibits extreme reduction possibilities not seen in the number. In even this small set of studies, the read and spontaneous speech highlight different generalizations, pointing out the need to examine both kinds of speech. While this paper cannot locate all factors responsible for the variation in these words, it begins to unravel some of them and their effects on different portions of function words.

In experimental phonetic research, we often come across cases of multiple perceptual cues to a phonemic distinction, even though this distinction may be seen traditionally as dependent on some single phonetic feature. The question arises as to the relative power of these cues. How equally do they share the burden of communicative relevance? For example, among the several cues that emanate from the timing of the valvular action of the larynx (Lisker and Abramson (1965); Abramson (1977)), fundamental-frequency perturbations (House and Fairbanks (1953)) have been shown by some studies, apparently starting with Haggard, Ambler and Callow (1970) and Fujimura (1971), to help in the perceptual differentiation of voiced and voiceless stop consonants; however, recent work (Abramson and Lisker (1985)) suggests that this cue has very limited efficacy compared with other acoustic consequences of voice timing.
