Developmental Change in Infants' Detection of Visual Faces that Match Auditory Vowels

Infants demonstrate robust audiovisual (AV) perception, detecting, for example, which visual face matches auditory speech in many paradigms. For simple phonetic segments, like vowels, previous work has assumed developmental stability in AV matching. This study shows dramatic differences in matching performance for different vowels across the first year of life: 3‐, 6‐, and 9‐month‐olds were familiarized for 40 sec with a visual face articulating a vowel in synchrony with auditory presentations of that vowel, but crucially, the mouth of the face was occluded. At test, infants were shown two still photos of the same face without occlusion for 1 min in silence. One face had a static articulatory configuration matching the previously heard vowel, while the other face had a static configuration matching a different vowel. Three auditory vowels were used: /a/, /i/, and /u/. Results suggest that AV matching performance varies according to age and to the familiarized vowel. Interestingly, results are not linked to the frequency of vowels in auditory input, but may instead be related to infants' ability to produce the target vowel. A speculative hypothesis is that vowel production in infancy modulates AV vowel matching.     

A Cross‐linguistic Examination of Toddlers’ Interpretation of Vowel Duration

Languages differ in their phonological use of vowel duration. For the child, learning how duration contributes to lexical contrast is complicated because segmental duration is implicated in many different linguistic distinctions. Using a language‐guided looking task, we measured English and Dutch 21‐month‐olds’ recognition of familiar words with normal or manipulated vowel durations. Dutch but not English learners were affected by duration changes, even though distributions of short and long vowels in both languages are similar, and English uses vowel duration as a cue to (for example) consonant coda voicing. Additionally, we found that word recognition in Dutch toddlers was affected by shortening but not lengthening of vowels, matching an asymmetry also found in Dutch adults. Considering the subtlety of the cross‐linguistic difference in the input, and the complexity of duration as a phonetic feature, our results suggest a strong capacity for phonetic analysis in children before their second birthday.     

Infant‐directed speech to infants at risk for dyslexia: A novel cross‐dyad design

When mothers speak to infants at risk for developmental dyslexia, they do not hyperarticulate vowels in their infant‐directed speech (IDS). Here, we used an innovative cross‐dyad design to investigate whether the absence of vowel hyperarticulation in IDS to at‐risk infants is a product of maternal infant‐directed behavior or of infants’ parent‐directed cues. Interactions between mothers and infants who were at risk or not at risk for dyslexia were recorded in three conditions: when mothers interacted with (a) their own infants, (b) infants who were not their own but of the same risk status, and (c) infants who were not their own and of the opposite risk status. This design revealed both infant and parent effects. Mothers of not‐at‐risk infants hyperarticulated vowels significantly more when speaking to not‐at‐risk than to at‐risk infants. In contrast, mothers of at‐risk infants hyperarticulated vowels significantly less than NAR mothers, and this was irrespective of infant status. Mothers of not‐at‐risk infants thus adjusted their IDS to the infant's risk status, while mothers of at‐risk infants did not. We suggest that IDS is determined reciprocally by characteristics of both partners in the dyad: Both infant and maternal factors are essential for the vowel hyperarticulation component of IDS.     

Vowel harmony redux: Correct sounds,English loan words,and the sociocultural life of a phonological structure in Korean1

This paper examines an ideology of standard pronunciation and spelling of English loan words in South Korea through the lens of Korean vowel harmony. I focus specifically on the alternation between an older Japanese‐style ‘a’[a] and a newer Korean‐style ‘?’[?] for the mapping of mid‐vowels from English to Korean. The opposition between ‘a’ and ‘?’ also figures into the dichotomy of vowel classes between ‘yang’ or ‘light’ vowels and ‘yin’ or ‘dark’ vowels in Korean vowel harmony. This opposition is pervasive in Korean's rich stock of denotationally iconic words (e.g. onomatopoeia), where ablaut between vowel classes produces semantic and pragmatic contrasts. I suggest that this latter structure of phonological opposition has an influence on speakers’ perceptions of vowel difference and associated values in English loan words, despite an overarching ideology of standard pronunciation that is based on assumptions about phonetic fidelity. ? ??? ?? ???? ?? ?? ? ??? ? ?????? ????? ?? ??? ???? ????. ??, ?? ???? ‘?’[a]? ‘?’[?]? ??(mapping)?? ?? ??? ??. ??? ?? ????? ‘?’? ?? ?? ??? ? ?????? ???? ???? ??(正音)?? ?????? ??. ?? ‘?’? ????? ???, ??? ???? ??? ????? ?(音)?? ???? ??. ???, ‘?’/‘?’? ??? ??? ???? ?? ????? ????? ??; ?, ??? ????? ????? ??? ??. ??, ????? ???? ????? ??? ??? ??? ? ? ??. ????, ????? ????? ????? ??? ?? ???? ????? ??? ??? ???.

Infant Recognition of Hebrew Vocalic Word Patterns

The ability of infants to recognize phonotactic patterns in their native language is widely acknowledged. However, the specific ability of infants to recognize patterns created by nonadjacent vowels in words has seldom been investigated. In Semitic languages such as Hebrew, groups of multisyllabic words are identical in their nonadjacent vowel sequences and stress position but differ in the consonants interposed between the vowels. The goals of this study were to assess whether infants learning Hebrew show a preference for (1) a nonadjacent vocalic pattern or template, common in Hebrew nouns (CéCeC), over a nonattested nonadjacent vocalic pattern (CóCoC), and (2) a nonadjacent vocalic pattern common in Hebrew words (CaCóC) over an existing but less common pattern (CaCéC). Twenty Hebrew‐learning infants aged 8 to 11 months were presented with lists of nonsense words featuring the first two patterns (Experiment 1), and 20 were presented with nonsense words featuring the second two patterns (Experiment 2). The results showed longer listening to CéCeC than to CóCoC lists and to CaCóC than to CaCéC lists, suggesting that infants recognized the common nonadjacent vocalic patterns in both cases. The study thus demonstrates that Hebrew‐learning infants are able to disregard the intervening consonants within words and generalize their vocalic pattern to previously unheard nonwords, whether this pattern includes identical or different vowels and regardless of the rhythmic pattern of the word (trochaic or iambic). Analysis of the occurrence of the relevant vowel patterns in input speech in three Hebrew corpora (two addressed to children and one to adults) suggests that exposure to these patterns in words underlies the infants' preferences.     

Emerging Hispanic English: New dialect formation in the American South

Although stable Hispanic populations have existed in some regions of the United States for centuries, other regions, including the mid‐Atlantic South, are just experiencing the emergence of permanent Hispanic communities. This situation offers an ideal opportunity to examine the dynamics of new dialect formation in progress, and the extent to which speakers acquire local dialect traits as they learn English as a second language. We focus on the production of the /ai/ diphthong among adolescents in two emerging Hispanic communities, one in an urban and one in a rural context. Though both English and Spanish have the diphthong /ai/, the Southern regional variant of the benchmark local dialect norm is unglided, thus providing a local dialect alternative. The instrumental analysis of /ai/ shows that there is not pervasive accommodation to the local norm by Hispanic speakers learning English. There is, however, gradient, incremental adjustment of the /ai/, and individual speakers who adopt local cultural values may accommodate to the local dialect pattern.     

'I don't speak with a Geordie accent, I speak, like, the Northern accent': Contact-induced levelling in the Tyneside vowel system

Evidence is presented in this paper of the levelling of the Tyneside (Newcastle) English vowel system toward that of a putative regional standard. This process is hypothesised to follow from the fragmentation of tight-knit urban communities that formed after large-scale immigration to Tyneside from elsewhere in the British Isles during the 18th and 19th centuries. High levels of dialect contact brought about by this influx are argued to have promoted the creation of an urban koiné, which in its contemporary form appears increasingly to be losing specifically local features. In addition to contact and mobility as agents of change, the history of unusually acute stigma attached to Tyneside speech should be considered. These and other social factors inform an analysis of the FACE and GOAT variables in the speech of 32 contemporary Tyneside English speakers of various ages, both sexes and from two social class groups.     

Environmental Influences on Infants’ Native Vowel Discrimination: The Case of Talker Number in Daily Life

Both quality and quantity of speech from the primary caregiver have been found to impact language development. A third aspect of the input has been largely ignored: the number of talkers who provide input. Some infants spend most of their waking time with only one person; others hear many different talkers. Even if the very same words are spoken the same number of times, the pronunciations can be more variable when several talkers pronounce them. Is language acquisition affected by the number of people who provide input? To shed light on the possible link between how many people provide input in daily life and infants’ native vowel discrimination, three age groups were tested: 4‐month‐olds (before attunement to native vowels), 6‐month‐olds (at the cusp of native vowel attunement) and 12‐month‐olds (well attuned to the native vowel system). No relationship was found between talker number and native vowel discrimination skills in 4‐ and 6‐month‐olds, who are overall able to discriminate the vowel contrast. At 12 months, we observe a small positive relationship, but further analyses reveal that the data are also compatible with the null hypothesis of no relationship. Implications in the context of infant language acquisition and cognitive development are discussed.     

Twelve‐Month‐Olds Know Their Cups From Their Keps and Tups

Fourteen‐month‐olds are sensitive to mispronunciations of the vowels and consonants in familiar words (N. Mani & K. Plunkett (2007), Journal of Memory and Language, 57, 252; D. Swingley & R. N. Aslin (2002), Psychological Science, 13, 480). To examine the development of this sensitivity further, the current study tests 12‐month‐olds’ sensitivity to different kinds of vowel and consonant mispronunciations of familiar words. The results reveal that vocalic changes influence word recognition, irrespective of the kinds of vocalic changes made. While consonant changes influenced word recognition in a similar manner, this was restricted to place and manner of articulation changes. Infants did not display sensitivity to voicing changes. Infants’ sensitivity to vowel mispronunciations, but not consonant mispronunciations, was influenced by their vocabulary size—infants with larger vocabularies were more sensitive to vowel mispronunciations than infants with smaller vocabularies. The results are discussed in terms of different models attempting to chart the development of acoustically or phonologically specified representations of words during infancy.     

Flight of the Conchords: Recontextualizing the voices of popular culture1

Folk‐comedy duo, Flight of the Conchords, have become one of New Zealand's most successful musical exports, having attracted a large international audience through their American‐produced TV series. One of their central comic devices is to stylize well‐known singers and their music. This article focuses on how Flight of the Conchords shift their phonetic style towards that of various target personas, and how they maintain their own voices as comedians in the process. An acoustic analysis compares Flight of the Conchords’ pronunciation of four vowels (kit , dress , trap , and goat) to the pronunciation of the pop singers being stylized. Both Jemaine Clement and Bret McKenzie manipulate their vowel production towards that of the targeted personas. They also maintain some distance from their targeted roles through a range of devices including the use of exaggerated phonetic style. Through their performances, Flight of the Conchords recontextualize and parody a range of popular cultural products, continuing the enregisterment of certain phonetic styles with the voices of well‐known characterological figures.     

A sociolinguistic application of Bakhtin's authoritative and internally persuasive discourse

Through the use of two central Bakhtinian concepts, authoritative and internally persuasive discourse (word), this paper examines the tension between the ideology of linguistic hegemony as a source of power in the Greek public sphere and the condition of language shift faced by the Albanian‐speaking communities of modern Greece. I argue here that a cautious application of these two notions, which are relevant to linguistic ideology, can reveal crucial aspects of two processes: that of subordination to and that of questioning of the dominant linguistic ideology by local Albanian‐speaking communities. Thus, in language shift contexts, it is possible that no simple relations obtain that place social agents in unquestionable and easily predictable positions. Such an approach proves useful for the sociolinguistic study of threatened language communities.     

Sing for me,Mama! Infants' discrimination of novel vowels in song

When adults speak or sing with infants, they sound differently than in adult communication. Infant-directed (ID) communication helps caregivers to regulate infants' emotions and helps infants to process speech information, at least from ID-speech. However, it is largely unclear whether infants might also process speech information presented in ID-singing. Therefore, we examined whether infants discriminate vowels in ID-singing, as well as potential differences with ID-speech. Using an alternating trial preference procedure, infants aged 4–6 and 8–10 months were tested on their discrimination of an unfamiliar non-native vowel contrast presented in ID-like speech and singing. Relying on models of early speech sound perception, we expected that infants in their first half year of life would discriminate the vowels, in contrast to older infants whose non-native sound perception should deteriorate, at least in ID-like speech. Our results showed that infants of both age groups were able to discriminate the vowels in ID-like singing, while only the younger group discriminated the vowels in ID-like speech. These results show that infants process speech sound information in song from early on. They also hint at diverging perceptual or attentional mechanisms guiding infants' sound processing in ID-speech versus ID-singing toward the end of the first year of life.

Developmental change in English-learning children's interpretations of salient pitch contours in word learning

To efficiently recognize words, children learning an intonational language like English should avoid interpreting pitch-contour variation as signaling lexical contrast, despite the relevance of pitch at other levels of structure. Thus far, the developmental time-course with which English-learning children rule out pitch as a contrastive feature has been incompletely characterized. Prior studies have tested diverse lexical contrasts and have not tested beyond 30 months. To specify the developmental trajectory over a broader age range, we extended a prior study (Quam & Swingley, 2010), in which 30-month-olds and adults disregarded pitch changes, but attended to vowel changes, in newly learned words. Using the same phonological contrasts, we tested 3- to 5-year-olds, 24-month-olds, and 18-month-olds. The older two groups were tested using the language-guided-looking method. The oldest group attended to vowels but not pitch. Surprisingly, 24-month-olds ignored not just pitch but sometimes vowels as well—conflicting with prior findings of phonological constraint at 24 months. The youngest group was tested using the Switch habituation method, half with additional phonetic variability in training. Eighteen-month-olds learned both pitch-contrasted and vowel-contrasted words, whether or not additional variability was present. Thus, native-language phonological constraint was not evidenced prior to 30 months (Quam & Swingley, 2010). We contextualize our findings within other recent work in this area.     

The Formation and Development of New Zealand English: Interaction of Gender-Related Variation and Linguistic Change

This research assesses the relative roles played by men and women in the development of New Zealand English. Real-time evidence on the development of NZ English over the past fifty years is provided by comparison of speakers recorded in 1948 and their present day descendants recorded recently. Elements of two vowel shifts are studied, and particular attention is paid to the vowel variables in words such as MOUTH, TRAP and DRESS. Results indicate that women lead in changes which are new and dynamic, but lag behind men in the use of variables representing older changes. While these results mirror patterns of gender-related variation observed in other contexts, explanations in terms of prestige which are often assumed to account for this pattern of variation are found to be inadequate in the New Zealand case. Rather, a hypothesis in terms of dialect contact, and specifically women's preferred discourse strategies in contact situations, is used to explain the process and progress of linguistic change in NZ English.     

Ethnic patterns in the phonetics of Montreal English

Most North American cities no longer display strong ethnic differentiation of speech within the European‐origin population. This is not true in the English‐speaking community of Montreal, Canada, where English is a minority language. Differences in the phonetic realization of vowels by Montrealers of Irish, Italian, and Jewish ethnic origin are investigated by means of acoustic analysis. A statistical analysis of ethnic differences in formant frequencies shows that ethnicity has a significant effect on several variables, particularly the phonetic position of /u:/ and /ou/ and the allophonic conditioning of /æ/ and /au/ before nasal consonants. The unusual tenacity of ethnophonetic variation in Montreal English is explained in light of the minority status of English, and the social and residential segregation of ethnic groups in distinct neighborhoods, which limits their exposure to speakers of Standard Canadian English who might otherwise serve as models for assimilation.

How 15‐month‐old infants process morphologically complex forms in an agglutinative language?

While phonological development is well‐studied in infants, we know less about morphological development. Previous studies suggest that infants around one year of age can process words analytically (i.e., they can decompose complex forms to a word stem and its affixes) in morphologically simpler languages such as English and French. The current study explored whether 15‐month‐old infants learning Hungarian, a morphologically complex, agglutinative language with vowel harmony, are able to decompose words into a word stem and a suffix. Potential differences between analytical processing of complex forms with back versus front vowels were also studied. The results of Experiment 1 indicate that Hungarian infants process morphologically complex words analytically when they contain a frequent suffix. Analytic processing is present both in the case of complex forms with back and front vowels according to the results of Experiment 2. In light of the results, we argue for the potential relevance of the early development of analytic processing for language development.     

Better Processing of Consonantal Over Vocalic Information in Word Learning at 16 Months of Age

Previous research using the name‐based categorization task has shown that 20‐month‐old infants can simultaneously learn 2 words that only differ by 1 consonantal feature but fail to do so when the words only differ by 1 vocalic feature. This asymmetry was taken as evidence for the proposal that consonants are more important than vowels at the lexical level. This study explores this consonant‐vowel asymmetry in 16‐month‐old infants, using an interactive word learning task. It shows that the pattern of the 16‐month‐olds is the same as that of the 20‐month‐olds. Infants succeeded with 1‐feature consonantal contrasts (either place or voicing) but were at chance level with 1‐feature vocalic contrasts (either place or height). These results thus contribute to a growing body of evidence establishing, from early infancy to adulthood, that consonants and vowels have different roles in lexical acquisition and processing.     

Enhancing vowel discrimination using constructed spelling

In a computerized task, an adult with intellectual disabilities learned to construct consonant-vowel-consonant words in the presence of corresponding spoken words. During the initial assessment, the participant demonstrated high accuracy on one word group (containing the vowel-consonant units it and un) but low accuracy on the other group (containing the units ag and ed). Errors occurred almost exclusively in the vowel position. Training the group with low accuracy increased accuracy on the trained word group but decreased the accuracy on the untrained, but initially accurate, group. High accuracy on both groups together occurred only after added training in which all five vowels (a, e, i, u, and o) were taught together in words that differed only in the vowel. These findings indicate the importance of carefully arranging examples and nonexamples to sharpen stimulus control. The findings also illustrate a promising step in the development of effective instructional programming for remediation of medial-vowel errors, which can be a source of difficulty in early reading instruction.
