Normal Language requires the integration of formal, conceptual, and pragmatic knowledge. It appears to involve the analytic processing of the left hemisphere and the holistic processing of the right. To study hemisphere involvement in language processing, patients with unilateral right or left hemisphere lesions and a matched neurologically normal control group were tested on their ability to perceive stress and intonation contrasts in words and phrases of varying length. The results suggest that both hemispheres are involved in normal language processing, each in a qualitatively different way. Whereas the left hemisphere appears to work from the bottom up, analyzing information sequentially and arriving at the overall pattern, the right hemisphere works from the top down, beginning with the overall pattern and working to fill in the details. Moreover, the importance of each hemisphere's participation may change in response to different grammatical and contexual variables.

A student's proficiency in a language is usually assessed by measuring his competence in understanding, speaking, reading, and writing. Foreign language training programs differ in the emphases placed on the development of each of these four basic language skills. Some of these differences are directly related to the specific needs of particular student populations while others are related to the method of instruction the teacher has adopted. [...]

The relationship between word form and word meaning has been debated since early Greek philosophy. Conventionally, the relationship is held to be arbitrary: that there is no natural connection between a word and what it represents (de Saussure 1959). In contrast, examples of sound symbolism undermine this linguistic tenet by demonstrating non-arbitrary word meanings conveyed in details of the acoustic signal of the words themselves. The Affect Induction model of animal communication offers a natural explanation for some forms of sound symbolism in language. According to the Affect Induction model, the physical properties of signals influence receiver affect and behavior in specific ways through relatively direct effects on core sensory, psychological and affective processes. To investigate the possible implications of this model for sound symbolism in human language, a set of studies was conducted on the classic “bouba-kiki” phenomenon. An analysis was subsequently undertaken to extend the results of experiments to several corpuses of real words classically associated with divergent affective themes. Results suggest that the Affect Induction model might account for some forms of sound symbolism, as instantiated in real word usage. / viii, 89 leaves : ill. ; 28 cm

This thesis reports on findings from a year-long sociolinguistic ethnography at an all girls’ high school in New Zealand which is referred to as Selwyn Girls’ High (SGH). The study combines the qualitative methods of ethnography with the quantitative methods of acoustic phonetic analysis and experimental design. At the school, there were a number of different groups (e.g. The PCs, The Pasifika Group, The BBs), each forming a community of practice where the different members actively constructed their unique social personae within the context of the group. There was a dichotomy between the groups based on whether they ate lunch in the common room (CR) or not (NCR) and this division reflected the individual speakers’ stance on whether they viewed themselves as “normal” or different from other girls at the school. In-depth acoustic analysis was conducted on tokens of the word like from the girls’ speech. This is a word with a number of different pragmatic functions, such as quotative like (I was LIKE “yeah okay”), discourse particle like (It was LIKE so boring), and lexical verb like (I LIKE your socks). The results provide evidence of acoustically gradient variation in the girls’ realisations of the word like that is both grammatically and socially conditioned. For example, quotative like was more likely to have a shorter /l/ to vowel duration ratio and be less diphthongal than either discourse particle like or grammatical like and there was a significant difference in /k/ realisation depending on a combination of the token’s pragmatic function and whether the speaker ate lunch in the CR or not. Additionally, three speech perception experiments were conducted in order to examine the girls’ sensitivity to the relationship between phonetic variants, lemma-based information, and social factors. The results indicate that perceivers were able to distinguish between auditory tokens of the different functions of like in a manner that was consistent with trends observed in production. Perceivers were also able to extract social information about the speaker depending on phonetic cues in the stimuli. Taken together, the results provide evidence that lemmas with a shared wordform can have different phonetic realisations, that individuals can manipulate these realisations in the construction of their social personae, and that individuals can use lemma-based phonetic trends from production to identify a word. These results have implications for how phonetic, lemma, and social information are stored in the mind and, together, they are used to inform a unified model of speech production, perception and identity construction.

This thesis examines the occurrence of Canadian Raising in Manitoba, using acoustic-spectral analysis. Factors such as lexical frequency and morphological complexity are examined to determine their role in Canadian Raising production within the sample population. One of the key findings is that what are usually analyzed as “raised” phones in pre-voiceless context are considerably shorter than non-raised (pre-voiced) phones, but do not exhibit substantial differences in terms of vowel quality. A method of multiple-timepoint spectral analysis used to achieve this finding is described in detail. Examination of raising-like diphthongs before /ɹ/ indicates that vowel duration differences exist in different contexts. There is some indication that morphological complexity is related to variants of “raised” phones, such that complex morphology is correlated with longer duration.

Phonetic aspects of mother-infant interaction are discussed in light of a functionalist Mother-infant phonetic interaction (MIPhI) model. Adults addressing infants typically use a speech style (infant-directed speech, IDS) characterized by, for instance, extensive suprasegmental (prosodic) modulations. This type of speech seems to interest young infants whose active experience with the spoken language appears to focus their speech perception on the phonological properties of the ambient language during the first year of life. This thesis consists of four articles discussing phonetic modifications at the suprasegmental, segmental and phonological levels, based on data from six Swedish mothersí IDS to their 3-month-olds. The first study concerns the tonal word accent 2 in disyllabic words, and shows how the lexical, bimodal, tonal characteristics of this accent are enhanced in IDS as compared to adult-directed speech (ADS). The second is a cross-linguistic investigation of vowel formant frequencies in Swedish, Am. English and Russian IDS. It shows that vowels like /i/, /u/, and /a/ are more clearly separated in IDS than in ADS, in all three languages. The third study addresses the voiced /voiceless contrast in stop consonants as measured by voice onset time (VOT) and shows that stop consonants seem to be poorly separated in early IDS samples. The fourth study investigates the quantity distinction in V:C and VC: sequences and indicates that this phonological contrast is well maintained in the IDS. Adult data are discussed within the MIPhI model, assuming that suprasegmental and segmental specifications in IDS follow different phonetic specification paths adapted to the infantsí capacities as these develop over the first 18 months of life. The adultsí phonetic adaptations appear to reflect a selective strategy of presenting linguistic structure in a ìgift-wrappingî that is attractive and functional for the infant. / För att köpa boken skicka en beställning till exp@ling.su.se/ To order the book send an e-mail to exp@ling.su.se

The main goal of this thesis is to investigate the nature of an optional consonant deletion process, through an articulatory and acoustic study of word-final consonant clusters in Persian. Persian word-final coronal stops are optionally deleted when they are preceded by obstruents or the homorganic nasal /n/. For example, the final clusters in the words /næft/ “oil”, /suχt/ “burnt” and /qæsd/ “intention” are optionally simplified in fast/casual speech, resulting in: [næf], [suχ], and [qæs]. What is not clear from this traditional description is whether the coronal stop is truly deleted, or if a coronal gesture is produced, but not heard, because it is obscured by the adjacent consonants. According to Articulatory Phonology (Browman & Goldstein 1986, 1988, 1989, 1990a, 1990b, 1992, 2001), the articulatory gestures of the deleted segments can still exist even if the segments are not heard. In this dissertation, ultrasound imaging was used to determine whether coronal consonant deletion in Persian is categorical or gradient, and the acoustic consequences of cluster simplification were investigated through duration and spectral measures. This phonetic study enables an account for the optional nature of the cluster simplification process. A general phonological account is provided for the simplification of coda clusters with rising sonority, and the acoustic and articulatory investigation focuses on the simplification of clusters with coronal stops. Ten Persian-speaking graduate students from the University of Ottawa and Carleton University, five male and five female, aged 25-38 participated in the articulatory and acoustic study. Audio and real time ultrasound video recordings were made while subjects had a guided conversation with a native speaker of Persian. 662 tokens of word-final coronal clusters were auditorily classified into unsimplified and simplified according to whether they contained an audible [t]. Singleton coda consonants and singleton /t/s were also captured as controls. The end of the constriction plateau of C1 and beginning of constriction plateau of C3 were used to define a time interval in which to measure the coronal gesture as the vertical distance between the tongue blade and the palate. Smoothing Splines ANOVA was used in a novel way to compare tongue blade height over time across the three conditions. The articulatory results of this study showed that the gestures of the deleted segments are often still present. More specifically, the findings showed that of the clusters that sounded simplified, some truly had no [t] gesture, some had gestural overlap, and some had reduced gestures. In order to explain the optional nature of the simplification process, it is argued that the simplified tokens are the result of two independent mechanisms. Inevitable mechanical and physiological effects generate gesturally reduced and overlapped tokens whereas planned language-specific behaviors driven by phonological rules or abstract cognitive representations result in no [t]-gesture output. The findings of this study support the main arguments presented in Articulatory Phonology regarding the underlying reasons for sound patterns and sound change. The results of this study are further used to examine different sound change models. It is argued that the simplified tokens with totally deleted [t] gesture could be the result of speakers changing their representations based on other people’s gestural overlap. This would be instances of the Choice and Chance categories in Blevins’ (2004) CCC sound change model. The acoustic results did not find any major cues which could distinguish simplified tokens from controls. It is argued that articulatory data should form an integral part of phonetic studies.
