A number of recent studies have observed that phonetic variability is constrained across speakers, where speakers exhibit limited variation in the signalling of phonological contrasts in spite of overall differences between speakers. This previous work focused predominantly on controlled laboratory speech and on contrasts in English and German, leaving unclear how such speaker variability is structured in spontaneous speech and in phonological contrasts that make substantial use of more than one acoustic cue. This study attempts to both address these empirical gaps and expand the empirical scope of research investigating structured variability by examining how speakers vary in the use of positive voice onset time and voicing during closure in marking the stop voicing contrast in Japanese spontaneous speech. Strong covarying relationships within each cue across speakers are observed, while between-cue relationships across speakers are much weaker, suggesting that structured variability is constrained by the language-specific phonetic implementation of linguistic contrasts.

Purpose This paper aims to present findings from a recent study examining current records management as fit for digital government in Australia. Design/methodology/approach This paper draws on findings from the first phase of research for a postdoctoral degree. This research was collected through an online quantitative survey of government records management professionals in Australia. The survey’s purpose was to understand whether the profession has kept pace with advances in, and expectations of, digital government. Building on the findings of the survey, this paper explores the concepts of methodology and methods and applies them to current digital records management in the Australian Government. Methodology for Australian Government digital records management is contained in the 2015 Digital Continuity 2020 policy. However, measuring method proved more difficult. The researcher supplemented data published by the National Archives of Australia and the Department of Finance with data from her own research to measure the validity of methods by examining suitability of current requirements. Findings Australian Government records management professionals overwhelmingly feel requirements, organisational culture and behaviour form a barrier to implementing successful records management programs. This paper finds that the Australian Government is buying ten times more digital storage per year than the sum of all of the digital Australian Government records known. This suggests perhaps not all records are recognised. While there will always be more storage than records, the ratio should not be so inflated. Further problems are found with requirements for records management being seen as mostly paper-based and too resource intensive to be of use. This research, combined with a contemporary literature review, shows that there is an imbalance with the current methodology and methods and asks the question: Has a methodology (Digital Continuity 2020) been created without suitable and known methods being in place? Research limitations/implications The method for collecting survey data was based on self-reporting, which can lead to limitations in that the population sample may exaggerate their response or demonstrate bias. However, responses to the survey were common enough to eliminate bias. The study is based on the Australian Government; however, findings may translate to other governments. This paper presents findings from the first phase of research of a postdoctoral degree. Not all findings are presented, only those relevant to the topic. Originality/value As the Australian Government moves to become a true digital government, records management is still required to ensure accountability of government actions and decisions. However, while the government transitions to digital, and information stores continue to grow, the question of whether records management has kept up with the rapid pace of digital information flow and expansion does not need to be asked. Instead, the time has come to ask, “What can we do to keep up?”

The ‘voicing effect’ – the durational difference in vowels preceding voiced and voiceless consonants – is a well-documented phenomenon in English, where it plays a key role in the production and perception of the English final voicing contrast. Despite this supposed importance, little is known as to how robust this effect is in spontaneous connected speech, which is itself subject to a range of linguistic factors. Similarly, little attention has focused on variability in the voicing effect across dialects of English, bar analysis of specific varieties. Our findings show that the voicing of the following consonant exhibits a weaker-than-expected effect in spontaneous speech, interacting with manner, vowel height, speech rate, and word frequency. English dialects appear to demonstrate a continuum of potential voicing effect sizes, where varieties with dialect-specific phonological rules exhibit the most extreme values. The results suggest that the voicing effect in English is both substantially weaker than previously assumed in spontaneous connected speech, and subject to a wide range of dialectal variability.

This study quantifies vocalic variation that cannot be measured from the acoustic signal alone and develops methods of standardisation and measurement of articulatory parameters for vowels. Articulatory-acoustic variation in the GOOSE vowel was measured across three regional accents of the British Isles, using a total of eighteen speakers from the Republic of Ireland, Scotland and England, recorded with synchronous ultrasound tongue imaging, lip camera and audio. Single co-temporal measures were taken of tongue-body height and backness, lip protrusion, F1 and F2. After normalisation, mixed-effects modelling identified statistically-significant variation for region; tongue-body position was significantly higher and fronter for Irish and English speakers. Region was also significant for lip-protrusion measures, with Scottish speakers showing significantly smaller degrees of protrusion than English speakers. However, Region was only significant for acoustic height and not for frontness.Correlational analyses of all measures showed: a significant positive correlation between tongue-body height and acoustic height; a negative correlation between lip-protrusion and acoustic frontness; but no correlation between tongue-body frontness and acoustic frontness. Effectively, two distinct regional production strategies were found to result in similar normalised acoustic frontness measures for GOOSE: Scottish tongue-body positions were backer and lips less protruded, while English and Irish speakers had fronter tongue-body positions, but more protruded lips.

This article examines dialectical tensions in the health narratives of participants of the Employee Wellness Program (EWP) of a large public university in the southeastern United States. Semi-structured interviews ( n = 12) with team leaders in the program indicated that health is a multifaceted concept characterized by three pairs of dialectical tensions: autonomy versus connection, private versus public, and control versus lack of control. These findings suggest that to better promote health and wellness in the workplace, EWP staff should consider employees’ unique experiences and beliefs about health when designing organization-wide programs and campaigns.

In this article, we introduce recently released, publicly available resources, which allow users to watch videos of hidden articulators (e.g. the tongue) during the production of various types of sounds found in the world’s languages. The articulation videos on these resources are linked to a clickable International Phonetic Alphabet chart ([International Phonetic Association. 1999. Handbook of the International Phonetic Association: A Guide to the Use of the International Phonetic Alphabet. Cambridge: Cambridge University Press]), so that the user can study the articulations of different types of speech sounds systematically. We discuss the utility of these resources for teaching the pronunciation of contrastive sounds in a foreign language that are absent in the learner’s native language.

The cross-linguistic tendency of coda consonants to weaken, vocalize, or be deleted is shown to have a phonetic basis, resulting from gesture reduction, or variation in gesture timing. This study investigates the effects of the timing of the anterior tongue gesture for coda /r/ on acoustics and perceived strength of rhoticity, making use of two sociolects of Central Scotland (working- and middle-class) where coda /r/ is weakening and strengthening, respectively. Previous articulatory analysis revealed a strong tendency for these sociolects to use different coda /r/ tongue configurations-working- and middle-class speakers tend to use tip/front raised and bunched variants, respectively; however, this finding does not explain working-class /r/ weakening. A correlational analysis in the current study showed a robust relationship between anterior lingual gesture timing, F3, and percept of rhoticity. A linear mixed effects regression analysis showed that both speaker social class and linguistic factors (word structure and the checked/unchecked status of the prerhotic vowel) had significant effects on tongue gesture timing and formant values. This study provides further evidence that gesture delay can be a phonetic mechanism for coda rhotic weakening and apparent loss, but social class emerges as the dominant factor driving lingual gesture timing variation.

Background Child maltreatment is a significant public health problem. Group Family Nurse Partnership (gFNP) is a new intervention for young, expectant mothers implemented successfully in pilot studies. This study was designed to determine the effectiveness and cost-effectiveness of gFNP in reducing risk factors for maltreatment with a potentially vulnerable population. Methods A multi-site, randomized controlled, parallel-arm trial and prospective economic evaluation was conducted, with allocation via remote randomization (minimization by site, maternal age group) to gFNP or usual care. Participants were expectant mothers aged below 20 years with at least one live birth, or aged 20–24 years with no live births and with low educational qualifications. Data from maternal interviews at baseline and when infants were 2, 6 and 12 months, and video-recording at 12 months, were collected by researchers blind to allocation. Cost information came from weekly logs completed by gFNP family nurses and other service delivery data reported by participants. Primary outcomes measured at 12 months were parenting attitudes (Adult-Adolescent Parenting Index, AAPI-2) and maternal sensitivity (CARE Index). The economic evaluation was conducted from a UK NHS and personal social services perspective with cost-effectiveness expressed in terms of incremental cost per quality-adjusted life year (QALY) gained. The main analyses were intention-to-treat with additional complier average causal effects (CACE) analyses. Results Between August 2013 and September 2014, 492 names of potential participants were received of whom 319 were eligible and 166 agreed to take part, 99 randomly assigned to receive gFNP and 67 to usual care. There were no between-arm differences in AAPI-2 total (7 · 5/10 in both, SE 0.1), difference adjusted for baseline, site and maternal age group 0 · 06 (95% CI − 0 · 15 to 0 · 28, p = 0 · 59) or CARE Index (intervention 4 · 0 (SE 0 · 3); control 4 · 7 (SE 0 · 4); difference adjusted for site and maternal age group − 0 · 68 (95% CI − 1 · 62 to 0 · 16, p = 0 · 25) scores. The probability that gFNP is cost-effective based on the QALY measure did not exceed 3%. Conclusions The trial did not support gFNP as a means of reducing the risk of child maltreatment in this population but slow recruitment adversely affected group size and consequently delivery of the intervention.

BackgroundFamily Nurse Partnership (FNP) is a home-based nurse home-visiting programme to support vulnerable parents. Group Family Nurse Partnership (gFNP) has similar aims and materials and was demonstrated to be feasible in implementation evaluations.ObjectivesTo determine whether or not gFNP, compared with usual care, could reduce risk factors for maltreatment in a vulnerable group and be cost-effective.DesignA multisite randomised controlled parallel-group trial and prospective economic evaluation, with eligible women allocated (minimised by site and maternal age group) to gFNP or usual care.SettingCommunity locations in the UK.ParticipantsExpectant mothers aged InterventionForty-four sessions of gFNP (14 during pregnancy and 30 in the first 12 months after birth) were offered to groups of between 8 and 12 women with similar expected delivery dates (the difference between the earliest and latest expected delivery date ranged from 8 to 10 weeks depending on the group) by two family nurses (FNs), one of whom had notified her intention to practise as a midwife.Main outcome measuresParenting was assessed by a self-report measure of parenting opinions, the Adult Adolescent Parenting Inventory Version 2 (AAPI-2), and an objective measure of maternal sensitivity, the CARE-Index. Cost-effectiveness was primarily expressed in terms of incremental cost per quality-adjusted life-year (QALY) gained.Data sourcesInterviews with participants at baseline and when infants were aged 2, 6 and 12 months. Cost information from nurse weekly logs and other service delivery data.ResultsIn total, 166 women were enrolled (99 to the intervention group and 67 to the control group). Adjusting for site and maternal age group, the intention-to-treat analysis found no effect of gFNP on either of the primary outcomes. AAPI-2 total was 7.5/10 [standard error (SE) 0.1] in both arms [difference also adjusted for baseline 0.08, 95% confidence interval (CI) –0.15 to 0.28;p = 0.50]. CARE-Index maternal sensitivity mean: intervention 4.0 (SE 0.3); control 4.7 (SE 0.4) (difference –0.76, 95% CI –1.67 to 0.13;p = 0.21). The sensitivity analyses supported the primary analyses. The probability that the gFNP intervention was cost-effective based on the QALY measure did not exceed 3%. However, in terms ofchangein AAPI-2 score (baseline to 12 months), the probability that gFNP was cost-effective reached 25.1%. A separate discrete choice experiment highlighted the value placed by both pregnant women and members of the general population on non-health outcomes that were not included in the QALY metric.LimitationsSlow recruitment resulted in smaller than ideal group sizes. In some cases, few or no sessions took place owing to low initial group size, and small groups may have contributed to attrition from the intervention. Exposure to gFNP sessions was below maximum for most group members, with only 58 of the 97 intervention participants receiving any sessions; FNs were experienced with FNP but were mainly new to delivering gFNP.ConclusionsThe trial does not support the delivery of gFNP as a means of reducing the risk of child abuse or neglect in this population.Future workA randomised controlled trial with modified eligibility to enable first-time mothers aged Trial registrationCurrent Controlled Trials ISRCTN78814904.FundingThis project was funded by the National Institute for Health Research (NIHR) Public Health Research programme and will be published in full inPublic Health Research; Vol. 5, No. 9.

This paper contributes some new findings towards answering these general theoretical questions about real-time sound change and place. Our study exploits the possibilities offered for a longer-term perspective on real-time change by combining archive recordings from the First World War with those from a real- and apparent-time corpus from the 1970s. We consider three aspects of urban Scots, vowel quality and duration, and the realization of word-initial /l/, using acoustic phonetic measures. The real-time comparisons reveal change in progress in all three features. The direction of the changes is intriguing, since despite the substantial geographical and social changes which have taken place across the UK during especially the second half of the 20th century, and the impact of these in terms of contact-induced changes on urban British accents (e.g. Foulkes and Docherty 1999), it appears that linguistic and social factors to do with the dialect and its location have played a stronger role.

Sociophonetic real-time studies of vowel variation and change rely on acoustic analyses of sound recordings made at different times, often using different equipment and data collection procedures. The circumstances of a recording are known to affect formant tracking and may therefore compromise the validity of conclusions about sound changes made on the basis of real-time data. In this paper, a traditional F1/F2-analysis using linear predictive coding (LPC) was applied to the vowels /i u a/ extracted from spontaneous speech corpora of Glaswegian vernacular, that were recorded in the 1970s and 2000s. We assessed the technical quality of each recording, concentrating on the average levels of noise and the properties of spectral balance, and showed that the corpus comprised of mixed quality data. A series of acoustic vowel analyses subsequently unveiled that formant measurements using LPC were sensitive to the technical specification of a recording, with variable magnitudes of the effects for vowels of different qualities. We evaluated the performance of three commonly used formant normalisation procedures (Lobanov, Nearey and Watt-Fabricius) as well as normalisations by a distance ratio metric and statistical estimation, and compared these results to raw Bark-scaled formant data, showing that some of the approaches could ameliorate the impact of technical issues better than the others. We discuss the implications of these results for sociophonetic research that aims to minimise extraneous influences on recorded speech data while unveiling gradual, potentially small-scale sound changes across decades.

In order to remedy recurrent problems with false formant readings obtained with an automatic formant measurement routine, prototype-based automatic measurements were compared with manual formant measurements of the same uttered vowels. Two refinements that avoided false formants, one involving the option to skip measured formant racks and the other involving an expectation that successive formants would show successively lower amplitudes, were developed. This method was then applied to seven corpora representing diverse English dialects, with satisfactory results. The measurements of each vowel thus obtained were then subjected to principle component analysis to determine the orientation of the tokens in F1/F2 space. Most vowels exhibited distributions that apparently reflect degree of jaw opening. However, /u/ in North American varieties (with pre-/l/ and post-/j/ tokens excluded) showed mostly horizontal orientations, even when post-coronal and non-post-coronal tokens were considered separately. This pattern contrasted sharply with the vertical orientations of mid back vowels. /u/ was also the only vowel whose orientations coincided consistently with ongoing changes in the communities. We hypothesize that the factors responsible for the horizontal orientations of /u/ also lie behind its cross-linguistic tendency to shift frontward.

This paper presents the results of an analysis of the realization of word-final /k/ in a sample of read and casual speech by 28 female pupils from a single-sex Glaswegian high school. Girls differed in age, socioeconomic background, and ethnicity. Ejectives were the most usual variant for /k/ in both speech styles, occurring in the speech of every pupil in our sample. Our narrow auditory analysis revealed a continuum of ejective production, from weak to intense stops. Results from multinomial logistic regression show that ejective production is promoted by phonetic, linguistic and interactional factors: ejectives were used more in read speech, when /k/ occurred in the /-ŋk/ cluster (e.g.tank), and when the relevant word was either at the end of a clause or sentence, or in turn-final position. At the same time, significant interactions between style, and position in turn, and the social factors of age and ethnicity, show that the use of ejectives by these girls is subject to a fine degree of sociolinguistic control, alongside interactional factors. Finally, cautious comparison of these data with recordings made in 1997 suggests that these results may also reflect a sound change in progress, given the very substantial real-time increase in ejective realizations of /k/ in Glasgow over the past fourteen years.

For a century, phoneticians have noted a vowel merger in middle-class Scottish English, in the neutralisation of prerhotic checked vowels /ɪ/, /ʌ/, /ɛ/ to a central vowel, e.g. fir, fur, fern [fəɹ], [fəɹ] [fəɹn], or [fɚ], [fɚ], [fɚn]. Working-class speakers often neutralise two of these checked vowels to a low back [ʌ] vowel, fir, fur, both pronounced as [fʌɹ] or as [fʌʕ]. The middle-class merger is often assumed to be an adaptation towards the UK’s socially prestigious R.P. phonological system in which there is a long-standing three-way non-rhotic merger, to [ɜː]. However, we suggest a system-internal cause, that coarticulation with the postvocalic /r/ may play a role in the contemporary Scottish vowel merger. Indeed, strongly rhotic middle-class Scottish speakers have recently been found to produce postvocalic approximant /r/ using a markedly different tongue configuration from working-class Scottish speakers, who also tend to derhoticise /r/. We present the results of an ultrasound tongue imaging investigation into the differing coarticulatory effects of bunched and tongue-front raised /r/ variants on preceding vowels. We compare tongue shapes from two static points during rhotic syllable rimes. Phonetically, it appears that the bunched /r/ used by middle-class speakers exerts a stronger global coarticulatory force over preceding vowel tongue configurations than tongue-front raised /r/ does. This also results in a monophthongal rhotic target for what historically had been three distinct checked vowels. Phonologically, our view is that middle-class speakers of Scottish English have reduced the V+/r/ sequence to one segment; either a rhoticised vowel /ɚ/ or a syllabic rhotic /r/.

This article considers two instances of rapidly accelerating linguistic change in Glaswegian vernacular, th -fronting and l-vocalization , both typically associated with the Cockney dialect of London. Both changes have been underway for some time, but took off during the 1990s. In this article we consider a range of factors that are contributing to the rapid proliferation of these forms in the speech of inner-city Glaswegian adolescents. Our multivariate analysis shows very strong effects for linguistic factors, as well as strong positive correlations with social practices relating to local Glaswegian street style, some links with dialect contact with friends and family living in England, and—perhaps surprisingly—also positive correlations with strong psychological engagement with the London-based TV soap drama EastEnders . Our results suggest that the changes are being propelled by several processes: ongoing transmission and at the same time continuing diffusion through dialect contact; the local social meanings carried by these variants for these speakers; and strong engagement with a favorite TV drama. For this community at least, engaging with a favorite TV drama is an additional accelerating factor in rapid linguistic diffusion.

One of the most famous sound features of Scottish English is the short/long timing alternation of /i u ai/vowels, which depends on the morpho-phonemic environment, and is known of as the Scottish Vowel Length Rule (SVLR). These alternations make the status of vowel quantity in Scottish English (quasi-)phonemic but are also susceptible to change, particularly in situations of intense sustained dialect contact with Anglo-English. Does the SVLR change in Glasgow where dialect contact at the community level is comparably low? The present study sets out to tackle this question, and tests two hypotheses involving (1) external influences due to dialect-contact and (2) internal, prosodically-induced factors of sound change. Durational analyses of /i u a/ were conducted on a corpus of spontaneous Glaswegian speech from the 1970s and 2000s, and four speaker groups were compared, two of middle-aged men, and two of adolescent boys. Our hypothesis that the development of the SVLR over time may be internally constrained and interact with prosody was largely confirmed. We observed weakening effects in its implementation which were localised in phrase-medial unaccented positions in all speaker groups, and in phrase-final positions in the speakers born after the Second World War. But unlike some other varieties of Scottish or Northern English which show weakening of the Rule under a prolonged contact with Anglo-English, dialect contact seems to be having less impact on the durational patterns in Glaswegian vernacular, probably because of the overall reduced potential for a regular, everyday contact in the West given the different demographies.
