Auditory Analysis

Taking up anecdotal evidence, our general research aim is to investigate and to quantify the phonetic characteristics of Low German in different Northern German regions on the basis of detailed acoustic and auditory analyses. In the initial pilot study presented here, we focus on phonologically long vowels. The analyses are based on a sample of long-vowel tokens, which were produced by 18 Northern German speakers in spontaneous translations of the 'Wenker' sentences. The speakers had comparable dialectal competences, but came from different regions of Northern Germany, i. e. Schleswig, Holstein, Dithmarschen, Ostfriedland, Mecklenburg-Vorpommern, or Nordbrandenburg. The selected vowel tokens occurred in contexts that were phonetically controlled in terms of both consonantal coarticulation and prosodic structure. The acoustic analysis included measuring durations, formant frequencies (F1-F3) and intonation characteristics (pitch-accent F0 patterns). The auditory analysis was made by narrow phonetic transcriptions. The results of the two analyses agree in showing clear regional differences. They concern the distributions of the long vowels within the vowel space (i.e. the vowel qualities, their stabilities and phonetic distances to each other) as well as the pitch-accent intonation patterns that co-occur with the long vowels. Differences in vowel duration were not found. Nordbrandenburg and Schleswig are characterized by a wide spectrum of monophthongal long-vowel qualities. In contrast, the long vowels in Holstein, Mecklenburg-Vorpommern and Ostfriesland show less diverse quality differences in the vowel centre. However, overall the phonetic diversity is still there in terms of diphthongizations that start or end at very different qualities. The long vowels of Dithmarschen combine the two characteristics, i.e. diphthongal qualities with relatively large differences in the vowel centre. As regards the intonation patterns across the vowels, we found that Dithmarschen and Holstein are both characterized by rising-falling pitch-accent peaks, but with different alignments relative to the vowel boundaries. The pitch-accent intonations of our speakers from Ostfriesland also rose and fell across the vowel. However, unlike in all other regions they additionally showed a striking F0 shape with a long high plateau in between the rising and falling movements. Our results are discussed with regard to the current claims about the dialectal organization of Northern Germany.

The current research compares the acoustic correlates of pitch accent of two urban dialects of spoken Serbian, urban Niš and Novi Sad. We analyzed spontaneous speech of nineteen native speakers of Serbian with regard to vowel duration and fundamental frequency ratios. It was shown that the tone between the stressed and post-stressed vowel is generally falling in the speech of Niš, while in the speech of Novi Sad it reflects the tone of the expected pitch accent in that particular word. The same is true of the interval between the end of the stressed and the beginning of the post-stressed vowel, which is always rising in the speech of Niš. In Niš, speakers tend to produce vowels in words with falling accents as longer than in words with rising accents. On average, vowels are longer in the speech of Novi Sad. Bearing in mind that regional variations provide important forensic markers (Kašić and Đorđević 2009), this research aims to contribute to the discipline of forensic phonetics, in particular to speaker profiling. Its significance also lies in the fact that it examines spontaneous speech, and is thus relevant for forensic casework (Rose 2002; Nolan, de Jong, and McDougall 2006).

Abstract This study is part of a larger project on the influence of Arabic emphatics /tˁ, dˁ, δˁ, sˁ/ on adjacent Arabic vowels by considering three factors: vowel quality, vowel duration and directionality of emphasis spread. This paper investigates the influence of the voiced alveolar emphatic /dˁ/ on the six Modern Standard Arabic (MSA) monophthongs /ɐ – ɪ – ʊ – a: – i: – u:/ as produced by ten Jordanian speakers. The monophthongs in the adjacency of /dˁ/ are compared to those adjacent to the non-emphatic alveolar voiced stop /d/. Results indicate that in the emphatic context, the vowels are clearly retracted in the vowel space and that the extent of the emphatic influence in ‘preceding’ or ‘following’ contexts is not significantly different.

This paper investigates vowel adaptation in English-based loanwords by a group of Saudi Arabic speakers, concentrating exclusively on shared vowels between the two languages. It examines 5 long vowels shared by the two vowel systems in terms of vowel quality and vowel duration in loanword productions by 22 participants and checks them against the properties of the same vowels in native words. To this end, the study performs an acoustic analysis of 660 tokens (loan and native vowel sounds) through Praat to measure the first two formants (F1: vowel height and F2: vowel advancement) of each vowel sound at two temporal points of time (T1: the vowel onset and T2: the peak of the vowel) as well as a durational analysis to examine vowel length. It reports that measurements of the first two formants of vowels in native words appear to be stable during the two temporal points while values of the same vowel sounds occurring in loanwords are fluctuating from T1 to T2 and that durational differences exist between loanword vowels in comparison with vowels of native words in such a way that vowels in native words are longer in duration than the same vowels appearing in loanwords.

Acoustic analysis tests the hypothesis that the physical properties of Pakistani English (PaKE) vowels differ in terms of acoustic measurements of Native American English speakers. The present paper aims to document the physical behavior of English vowels produced by PaKE learners. The major goal of this paper is to measure the production of sound frequencies coupled with vowel duration. The primary aim of this paper is to explore the different frequencies and duration of the vowels involved in articulation of PaKE. English vowels selected for this purpose are: /æ/, /ɛ/, /ɪ/, /ɒ/ and /ə/. Total ten samplings were obtained from the department of computer science at Sindh Madressatul Islam University, Karachi. The study was based on the analysis of 500 (10×5×10=500) voice samples. Five vowel minimal pairs were selected and written in a carrier phrase [I say CVC now]. Ten speakers (5 male & five female) recorded their 500 voice samples using Praat speech processing tool and a high-quality microphone on laptop in a computer laboratory with no background sound. Three parameters were considered for the analysis of PaKE vowels i.e., duration of five vowels, fundamental frequency (F1 and F2). It was hypothesized that the properties of PaKE vowels are different from that of English native speakers. The hypothesis was accepted since the acoustic measurements of PaKE and English Native American speakers’ physical properties of sounds were discovered different.

Aims and objectives/purpose/research questions: This study investigates the sociolinguistic factors associated with the maintenance or loss of the mid-front vowel contrast in the Catalan spoken by Spanish-Catalan bilinguals in three districts of Barcelona. It addresses the following questions. (1) Is the mid-front vowel contrast kept in all the districts under study? Do we find differences across districts and/or age groups? (2) Is an auditory analysis of our data further supported by an acoustic analysis? (3) Which sociolinguistic factors help us predict whether the contrast is kept or lost? Design/methodology/approach: Participants in this study were 36 bilingual children and 36 bilingual adults who completed a picture-naming task. Participants lived in Gràcia/Eixample (two districts with a low degree of Spanish presence) or in Nou Barris (a district with a high degree of Spanish presence). Data and analysis: The production of words with target /ɛ/ and with target /e/ by each participant was recorded along with the answers to a sociolinguistic questionnaire. The spoken data were auditorily and acoustically analysed, and then statistically analysed in relation to different sociolinguistic factors that could account for the maintenance or loss of this vowel contrast. Findings/conclusions: Significant differences were found in the production of children across districts but not in that of adults. The children in Nou Barris show an advanced merger between /ɛ/ and /e/. The language in the environment seems to be the main factor, as the merger or maintenance of the contrast correlates with the language spoken by our participants’ peer group and close relatives. Originality: This research combines both an auditory and acoustic analysis of phonological data with sociolinguistic information about speakers from different districts in Barcelona. Significance/implications: This paper contributes to a better understanding of phonological variation within Barcelona and the sociolinguistic factors that are responsible for variation among its population.

The current research is done for the verification of two different claims. According to Kachru, (2005) that Punjabi English speakers are unable to create distinction between /Ɛ/ and /æ/ front vowels but Bilal et al. (2011) has refused this claim after verifying it in the speech of Punjabi speakers of Sargodha, Pakistan. If Bilal is right than there is a big need to study this claim in broader perspective. Therefore, in the current research, 9720 utterances (of 72 native Punjabi speakers from 12 districts of Punjab, Pakistan) are recorded and analyzed in PRAAT software. Data analysis is done in two steps i.e., (i) auditory analysis is done by listening wave files and (ii) acoustic analysis is based on the measurement of first three formant values (F1, F2, F3) and vowels’ duration. The results clarify that Pakistani Punjabi English speakers have maintained difference in short and long, stressed and unstressed articulation at word initial and medial positions. But the limited number of Lahori Punjabians could not maintain this difference at word medial position only. Consequently, this research highly supports Bilal’s claim in broader perspective but we cannot totally deny Kachru’s claim. Because we have also find traces of /Ɛ/ and /æ/ merger in our data as well and the reason might be the selection of research sample.

Studies describing acoustic characteristics of speech produced by individuals with dysarthria may help to explain intelligibility deficits for these speakers. One goal of the current study was to investigate the manner and extent to which nine speakers with mild to moderate dysarthria associated with amyotrophic lateral sclerosis (ALS) and nine healthy speakers acoustically distinguished /i/, / æ/, /u/, and /α/ in content and function words. A further aim was to evaluate the relationship between impaired speech in ALS and the magnitude of acoustic differences for vowels in content and function words. Speakers read the Farm Passage at a comfortable or habitual rate. F1 and F2 midpoint frequencies were measured, and vowel space areas were calculated. Vowel durations also were measured. The magnitude of F1, F2, vowel space area, and duration differences for vowels in content and function words was not statistically different for speakers with ALS and healthy controls. In addition, with the exception of /i/ produced by some speakers with ALS, vowel duration tended to be shorter in function words. Average F1 and F2 values for function words also tended to be centralized relative to content words. Although vowel space area differences for the two speaker groups were not statistically significant, there was a tendency for the difference in vowel space area for content and function words to be smaller for speakers with ALS than for controls. Regression analyses further indicated that the magnitude of temporal differences for vowels in content and function words was a better predictor of impaired speech than the magnitude of spectral differences for vowels in content and function words. One clinical implication is that individuals with ALS may benefit from therapy techniques targeting temporal properties of the acoustic signal.

In order to examine the role of hearing status in controlling coarticulation, eight English vowels in /bVt/ and /dVt/ syllables, embedded in a carrier phrase, were elicited from 7 postlingually deafened adults and 2 speakers with normal hearing. The deaf adults served in repeated recording sessions both before and up to a year after they received cochlear implants and their speech processors were turned on. Each of the two hearing control speakers served in two recording sessions, separated by about 3 months. Measures were made of second formant frequency at obstruent release and at 25 ms intervals until the final obstruent. An index of coarticulation, based on the ratio of F2 at vowel onset to F2 at midvowel target, was computed. Changes in the amount of coarticulation after the change in hearing status were small and nonsystematic for the /bVt/ syllables; those for the /dVt/ syllables averaged a 3% increase—within the range of reliability measures for the 2 hearing control speakers. Locus equations (F2 at vowel onset vs. F2 at vowel midpoint) and ratios of F2 onsets in point vowels were also calculated. Like the index of coarticulation, these measures tended to confirm that hearing status had little if any effect on coarticulation in the deaf speakers, consistent with the hypothesis that hearing does not play a direct role in regulating anticipatory coarticulation in adulthood. With the restoration of some hearing, 2 implant users significantly increased the average spacing between vowels in the formant plane, whereas the remaining 5 decreased that measure. All speakers but one also reduced vowel duration significantly. Four of the speakers reduced dispersion of vowel formant values around vowel midpoint means, but the other 3 did not show this effect.

<p>Although lay people confidently assert the existence of regional varieties of New Zealand English, linguists have produced very little evidence to support such claims. There are vocabulary items special to, or favoured by, the people of Southland and the West Coast of the South Island; there are traces of non-prevocalic /r/in Southland and Otago; and there are regional differences in the playground language of New Zealand school children. Attempts to identify further differences between regions have generally not been successful. In most cases linguistic evidence has pointed to either social class or ethnic variation, but not to regional variation. Nevertheless, many New Zealanders assert that a Taranaki variety of New Zealand English exists. This study was designed to test the validity of the claim by comparing samples of New Zealand English from Taranaki with samples from Wellington. The Taranaki sample included speakers from New Plymouth (population 50,000) and the South Taranaki dairy farming community. The Wellington sample was drawn from the Greater Wellington region extending from Porirua in the north to suburbs on the southern coast of the city. Interviewees were located by the social network approach, otherwise known as the 'friend of a friend' approach advocated by Lesley Milroy (1980, 1987a). An index of rural orientation was devised to indicate the degree to which a speaker was oriented towards town or country. This proved helpful in distinguishing between genuinely regional differences, and rural versus urban differences. Factors of gender and age were also considered. It has been claimed that Taranaki English has a 'sing-song' quality, suggesting that an investigation of the intonation of Taranaki speakers would be worthwhile. Comparing features of the intonation of a Taranaki sample with a Wellington sample, this thesis attempts to isolate and measure what contributes to the 'sing-song' perception of Taranaki English. 'Singsong' in this context was taken to mean that the speaker had dynamic pitch; in other words their speech was characterised by a lot of movement up and down in pitch. Auditory analysis of speech samples was undertaken, and intonation features were derived from that analysis. Averaging the number of times a speaker changed pitch direction in each intonation group and then in each accent unit provided global measures of changes in pitch direction. Analysis of nuclear accents gave an indication of whether speakers favoured tunes which were characterised by pitch movement. And analysis of the manner in which accents were approached, whether with a boosted step up in pitch, or with a more standard onset, provided a narrower focus on the amount of pitch movement present. Results indicated that, in general, most Taranaki speakers in the sample showed more pitch dynamism than the Wellingtonians; for some features the males showed more pitch dynamism than the females; and, overall, the elderly speakers showed more pitch dynamism than the younger speakers. There were, however, important exceptions to these generalisations. Factors of Location, Gander and Age interacted significantly for all but one of the features examined and there were clear indications that intonational patterns are undergoing change in both regions studied. Explanations for the exceptional cases are explored in the thesis, and sociolinguistic, social network and geolinguistic theories provide possible clues as to the sources of the differences. Evidence of differences in the degree of pitch dynamism present in the intonation of the Taranaki and Wellington speakers supports claims about regional variation in New Zealand English intonation, but it does not in itself prove the existence of a uniquely Taranaki or a uniquely Wellington way of speaking English.</p>

This vowel study looks at the intricate relationship between spectral  characteristics and vowel duration in the context of American English vowels, both from a native speaker (NS) and non-native speaker (NNS) perspective. The non-native speaker cohort is  homogeneous in the sense that all speakers have Serbian as their mother tongue, but have been long-time residents of the US. The phonetic context investigated in this study is /bVt/, where V is one of the American English monophthongs /i ɪ u ʊ ε æ ʌ ɔ ɑ/. The results of the acoustic analysis show that the NNS vowels are generally longer than the NS vowels. Furthermore, NNSs neutralise the vowel quality of two tense and lax pairs of vowels, /i ɪ/ and /u ʊ/, and rely more heavily on the phonetic duration when prononuncing them.
