Using Nigerian English in an international academic setting

This study examines the English pronunciation of a group of Nigerian students at a university in Sweden from the point of view of their intelligibility to two groups of listeners: 1) native speakers of English who are teachers at the university; 2) nonnative speakers of English who are teachers at the university. It is found that listeners who are accustomed to interacting with international students do better than those who are not, and that native speakers of English do no better or worse than non-native listeners. The conclusion is drawn that locally useful varieties of Nigerian English may not easily be used as for wider communication and that students preparing to study abroad would find it useful to gain access to a more widely intelligible variety

Models and Targets for the Pronunciation of English in Vietnam and Sweden

This paper aims to account for the factors that lie behind the choice of models and targets for the pronunciation of English by learners of English in Vietnam and in Sweden. English is the first foreign language in both Vietnam and in Sweden. English is used as a language of international communication in both settings. Swedish learners have much more exposure to spoken English than do Vietnamese learners and the Swedish language is more similar to English than is Vietnamese. These reasons, among others, explain why Swedish accents of English are typically considerably more intelligible than Vietnamese accents of English. Given that the majority of English speakers in the world are not native speakers, it is argued that the traditional learner target of approaching native speaker pronunciations is not appropriate for either group, but especially not for the Vietnamese learners. Instead maximal international intelligibility is a more useful target. To this end, learners need to be exposed to a variety of native and non-native models

Intonation in neurogenic foreign accent syndrome

Foreign accent syndrome (FAS) is a motor speech disorder in which changes to segmental as well as suprasegmental aspects lead to the perception of a foreign accent in speech. This paper focuses on one suprasegmental aspect, namely that of intonation. It provides an in-depth analysis of the intonation system of four speakers with FAS with the aim of establishing the intonational changes that have taken place as well as their underlying origin. Using the autosegmental-metrical framework of intonational analysis, four different levels of intonation, i.e. inventory, distribution, realisation and function, were examined. Results revealed that the speakers with FAS had the same structural inventory at their disposal as the control speakers, but that they differed from the latter in relation to the distribution, implementation and functional use of their inventory. In contrast to previous findings, the current results suggest that these intonational changes cannot be entirely attributed to an underlying intonation deficit but also reflect secondary manifestations of physiological constraints affecting speech support systems and compensatory strategies. These findings have implications for the debate surrounding intonational deficits in FAS, advocating a reconsideration of current assumptions regarding the underlying nature of intonation impairment in FAS

The acquisition of English L2 prosody by Italian native speakers: experimental data and pedagogical implications

This paper investigates Yes-No question intonation patterns in English L2, Italian L1, and English L1. The aim is to test the hypothesis that L2 learners may show different acquisition strategies for different dimensions of intonation, and particularly the phonological and phonetic components. The study analyses the nuclear intonation contours of 4 target English words and 4 comparable Italian words consisting of sonorant segments, stressed on the semi-final or final syllable, and occurring in Yes-No questions in sentence-final position (e.g., Will you attend the memorial?, Hai sentito la Melania?). The words were contained in mini-dialogues of question-answer pairs, and read 5 times by 4 Italian speakers (Padova area, North-East Italy) and 3 English female speakers (London area, UK). The results show that: 1) different intonation patterns may be used to realize the same grammatical function; 2) different developmental processes are at work, including transfer of L1 categories and the acquisition of L2 phonological categories. These results suggest that the phonetic dimension of L2 intonation may be more difficult to learn than the phonological one

Is It How You Look or Speak That Matters? - An Experimental Study Exploring the Mechanisms of Ethnic Discrimination

Using a unique laboratory experiment where subjects are asked to guess the test performance of candidates presented by facial portraits and voice messages, this paper explores the following questions: Are beliefs about performance affected by if a candidate is perceived to have looks that are non-stereotypical for the dominant population and do these beliefs change if the candidate has native-like versus accented speech? The experiment is conducted in Sweden and the results show that candidates not perceived as stereotypically Swedish are considered to be worse performers. These beliefs are found in within-gender but not in cross-gender evaluations and are not eliminated when additional performance-related information about the candidates is provided. When candidates are presented by both looks and speech, differential evaluations based on looks disappear. Instead, we find strong negative beliefs about performance for candidates that speak Swedish with a foreign accent implying that ethnic stereotypes associated with speech override stereotypes associated with appearance. The negative beliefs associated with foreign-accented speech are not supported by corresponding mean differences in the candidates’ actual test performance.Experiment; Appearance; Speech; Beliefs; Performance; Stereotypes

The perceptual importance of falling pitch for speakers from different dialects of Swedish

Falling pitch has long been argued to be a key feature in the distinction of Swedish pitch accents. In this paper, neurophysiological and behavioural evidence substantiating the perceptual importance of HL pitch contours at the word level is discussed. When presentedwith novel words, Swedes, regard-less of dialect,preattentively distinguished meaningfulwords with falling pitch.Falling pitch was also facilitative for tone mismatch detection.These responses tomeaningful HL contours in foreign words werelikely based on transfer from the native tongue, thus emphasisingthe importance of falling pitch in the discrimination of word accents in four Swedish dialectareas. However, while responses to falls were facilitated across dialects, additional dialect-dependent facilitation effects were found

Brain anatomical correlates of perceptual phonological proficiency and language learning aptitude

The present dissertation concerns how brain tissue properties reflect proficiency in two aspects of language use: the ability to use tonal cues on word stems to predict how words will end and the aptitude for learning foreign languages. While it is known that people differ in their language abilities and that damage to brain tissue cause loss of cognitive functions, it is largely unknown if differences in language proficiencies correlate with differences in brain structure. The first two studies examine correlations between cortical morphometry, i.e. the thickness and surface area of the cortex, and the degree of dependency on word accents for processing upcoming suffixes in Swedish native speakers. Word accents in Swedish facilitate speech processing by having predictive associations to specific suffixes, (e.g. fläckaccent1+en ‘spot+singular’, fläckaccent2+ar ‘spot+plural’). This use of word accents, as phonological cues to inflectional suffixes, is relatively unique among the world’s languages. How much a speaker depends on word accents in speech processing can be measured as the difference in response time (RT) between valid and invalid word accent-suffix combinations when asked to identify the inflected form of a word. This can be thought of as a measure of perceptual phonological proficiency in native speakers. Perceptual phonological proficiency is otherwise very difficult to study, as most phonological contrasts are mandatory to properly interpret the meaning of utterances. Study I compares the cortical morphometrical correlates in the planum temporale and inferior frontal gyrus pars opercularis in relation to RT differences in tasks involving real words and pseudowords. We found that thickness of the left planum temporale correlates with perceptual phonological proficiency in lexical words but not pseudowords. This could implicate that word accents are part of full-form representations of familiar words. Moreover, for pseudowords but not lexical words, the thickness of the inferior frontal gyrus pars opercularis correlates with perceptual phonological proficiency. This association could reflect a greater importance for decompositional analysis in which word accents are part of a set of rules listeners need to rely on during processing of novel words. In study II, the investigation of the association between perceptual phonological proficiency in real words with cortical morphometry is expanded to the entire brain. Results show that cortical thickness and surface area of anterior temporal lobe areas, known constituents of a ventral sound-to-meaning language-processing stream is associated with greater perceptual phonological proficiency. This is consistent with a role for word accents in aiding putting together the meaning of or accessing a whole word representation of an inflected word form. Studies III and IV investigate the cortical morphometric associations with language learning aptitude. Findings in study III suggest that aptitude for grammatical inferencing, i.e. the ability to analytically discern the rules of a language, is associated with cortical thickness in the left inferior frontal gyrus pars triangularis. Furthermore, pitch discrimination proficiency, a skill related to language learning ability, correlates negatively with cortical thickness in the right homologue area. Moreover, study IV, using improved imaging techniques, reports on a correlation between vocabulary learning aptitude and cortical surface area in the left inferior precuneus as well as a negative correlation between diffusional axial kurtosis and phonetic memory in the left arcuate fasciculus and subsegment III of the superior longitudinal fasciculus. However, the finding correlation between cortical thickness and grammatical inferencing skill from study III was not replicated in study IV.Taken together, the present dissertation shows that differences in some language proficiencies are associated with regionally thicker or larger cortex and more coherent white matter tracts, the nature and spatial locus of which depend on the proficiency studied. The studies add to our understanding of how language proficiencies are represented in the brain’s anatomy

Master of Science

thesisPresently, speech recognition is gaining worldwide popularity in applications like Google Voice, speech-to-text reporter (speech-to-text transcription, video captioning, real-time transcriptions), hands-free computing, and video games. Research has been done for several years and many speech recognizers have been built. However, most of the speech recognizers fail to recognize the speech accurately. Consider the well-known application of Google Voice, which aids in users search of the web using voice. Though Google Voice does a good job in transcribing the spoken words, it does not accurately recognize the words spoken with different accents. With the fact that several accents are evolving around the world, it is essential to train the speech recognizer to recognize accented speech. Accent classification is defined as the problem of classifying the accents in a given language. This thesis explores various methods to identify the accents. We introduce a new concept of clustering windows of a speech signal and learn a distance metric using specific distance measure over phonetic strings to classify the accents. A language structure is incorporated to learn this distance metric. We also show how kernel approximation algorithms help in learning a distance metric
