The effects first language use phonological difficulty perception foreign accented speech [sic]

Listener perception of accentedness has been shown to be influenced by experience with L2 (measured by length of residence in US). However, frequency of L1 use and degree of phonological complexity (defined by the number of non-native phonetic features targeted) may provide more insight into the role of experience in the perception of accentedness.Three groups of listeners (monolingual English and Spanish [L1] speakers divided into two groups of high and low use of English [L2]) rated the accentedness of bilingual speakers who spoke with varying degrees of accentedness. The speakers read sentences adapted from Magan (1998) to include phonological aspects likely to be difficult for native Spanish speakers.Listeners performed similarly in rating speakers degree of accent

Spoken word recognition in quiet and in noise by native and non-native listeners: Effects of age of immersion and vocabulary size

In spoken word recognition, high-frequency words with few neighbors and less frequently occurring minimal pair neighbors (lexically easy words) are recognized more accurately than low-frequency words with many and more frequently occurring neighbors (lexically hard words). Bradlow and Pisoni (1999) found a larger easy hard word effect for non-native than native speakers of English. The present study extends this work by specifically comparing word recognition by non-native listeners with either earlier or later ages of immersion in an English-speaking environment to that of native English speakers. Listeners heard six lists of 24 words, each composed of 12 lexically easy and 12 lexically hard words in an open-set word identification task. Word lists were presented in quiet and in moderate noise. A substantially larger easy-hard word effect was obtained only for the later learners, but a measure of oral vocabulary size was significantly correlated with performance for the non-native listener groups only. Thus, the increased easy-hard word effect for non-native listeners appears to be explained as an effect of phonetic proficiency and/or vocabulary size on the structure of the lexical neighborhoods

Listener perception of accentedness has been shown to be influenced by experience with L2 (measured by length of residence in US). However, frequency of L1 use and degree of phonological difficulty (defined by the number of non-native phonetic features targeted) may provide more insight into the role of experience in the perception of accentedness. Three groups of listeners (monolingual English and Spanish [L1] speakers divided into two groups of high and low use of English [L2]) rated the accentedness of bilingual speakers who spoke with varying degrees of accentedness. The speakers read sentences adapted from Magan (1998) to include phonological aspects likely to be difficult for native Spanish speakers. Listeners performed similarly in rating speakers’ degree of accent. Amount of daily L1 use only influenced the ratings of the slightly accented group; the high-use bilingual group rated these speakers as more accented than the native English group, regardless of level of phonological difficulty. These results suggest that the high-use groups’ lack of L2 experience made them less perceptually sensitive to certain phonetic features of English. Because speakers did not make the predicted target errors, the listener groups may have based their ratings on features not targeted in this investigatio
