This study assessed the relation between non-native subjects’ age of learning (AOL) English and overall degree perceived foreign accent in their production sentences. The 240 native Italian (NI) subjects examined had begun Canada ages 2 23 yr, lived for an average 32 yr. Native English-speaking listeners used a continuous scale to rate sentences spoken by NI comparison group. Estimates AOL onset accents varied across ten who rated sentences, ranging from 3.1 11.6 yr (M=7.4). Foreign were...
This study examined the production and perception of English vowels by highly experienced native Italian speakers English. The subjects were selected on basis age at which they arrived in Canada began to learn English, how much continued use Italian. Vowel accuracy was assessed through an intelligibility test English-speaking listeners attempted identify spoken subjects. using a categorial discrimination test. later life less accurately produced perceived vowels. Neither two groups early...
This study used two methods to assess bilingual dominance in four groups of 18 Italian–English bilinguals, who were selected on the basis age arrival (AOA) Canada (early: 2–13 years; late: 15–26 years) and percentage use first language (L1), Italian (low L1 use: 1–15%; high 25–85%). Ratios derived from bilinguals' self-ratings ability speak understand compared English (the “verbal” self-rating ratios) read write “written” ratios). The ratio mean duration sentences produced by each was also...
This study examines the perception of English vowels by native speakers Italian. In two preliminary experiments, Italian university students who had lived in Canada for 3 months were found to have difficulty discriminating because they often identified both members each contrast as instances a single vowel. The participants other long-time residents Canada, assigned groups based on their age arrival from Italy (early vs. late) and percentage first language (L1) use (high L1 low use)....
ABSTRACT This study examined the English vowel productions of 240 native speakers Italian who had arrived in Canada at ages ranging from 2 to 23 years and 24 same community. The 11 vowels were rated for degree foreign accent by 10 listeners. An increase perceived accentedness as a function increasing age arrival was observed on every vowel. Not one be produced consistently native-like manner latest-arriving learners, even though they been living an average 32 years. However, high...
This study examined the recognition of English words by groups native speakers Italian who differed in age arrival Canada and amount continued language use. The dependent variable was number correctly repeated sentences presented noise. Significantly higher word scores were obtained for early than late bilinguals, bilinguals used seldom relatively often. A hierarchical regression analysis showed that participants' ability to perceive vowels consonants accounted a significant variance...
This study examined the production of English /b/ and perception short-lag /b d g/ tokens by four groups bilinguals who differed according to their age arrival (AOA) in Canada from Italy amount self-reported native language (L1) use. A clear difference emerged between early (mean AOA= 8 years) late 20 years). The showed a stronger L1 influence than did on both stops. In experiment 2, produced larger percentage prevoiced (NE) speakers did. 3, misidentified as /p t k/ more often NE Experiment...
Speech error data have been used to argue for the psychological reality of distinctive features and phonemes as well hierarchical ordering levels processing speech production. The models production that emerged from analysis these are nearly unanimous in characterizing (implicitly or explicitly) motor output level entirely governed by prior selection larger units, especially phoneme. This study reports on laboratory elicitation sublexical errors means tongue twisters. Simultaneous audio...
Abstract The primary aim of this study was to determine if fluent early bilinguals who are highly experienced in their second language (L2) can produce L2 vowels a way that is indistinguishable from native speakers’ vowels. subjects were speakers Italian began learning English when they immigrated Canada as children or adults (‘early’ vs. ‘late’ bilinguals). subdivided into groups differing amount continued L1 use (early-low early-high). In experiment 1, English-speaking listeners rated 11...
Abstract This study examined the identification of English consonants in noise by native speakers Italian. The effect age first exposure to was evaluated comparing three groups subjects who continued use Italian relatively often but differed according their arrival (AOA) Canada from Italy (early: 7, mid: 14, late: 19 years). late group made more errors identifying word-initial than early did; however, AOA nonsignificant for word-final stops. amount language (L1) two bilinguals were matched...
Immigrants' age of arrival (AOA) in a country where second language (L2) must be learned has consistently been shown to affect the degree perceived L2 foreign accent. Although effect AOA appears strong, is typically correlated with other variables that might influence This study examined pronunciation English by native Italian immigrants Canada who differed AOA. As previous research, those arrived as young adults (late learners) were somewhat older at time testing, and produced longer...

The primary aim of this study was to account for the finding that late bilinguals produce longer English sentences than early bilinguals. In Experiment 1, Italians who immigrated Canada either between age 2–13 years (“early bilinguals”) or 15–28 (“late repeated matched and Italian following an aural model. produced shorter sentences, whereas showed opposite pattern. same countervailing pattern evident in 2, where shortened by 20% when instructed repeat as rapidly possible. Subgroups reported...
