This paper tests the predictions of the vocabulary-tuning model of second language (L2) rephonologization in the domain of L2 segmental production. This model proposes a facilitating effect of adults' L2 vocabulary expansion on L2 perception and production and suggests that early improvements in L2 segmental production may be positively associated…

Adult second-language (L2) learners' perception of L2 phonetic segments is influenced by first-language phonological and phonetic properties. It was recently proposed that L2 vocabulary size in adult learners is related to changes in L2 perception (perceptual assimilation model), analogous to the emergence of first-language phonological function…

The study tested the effect of three factors on Arab children's (N = 256) phoneme isolation: "phoneme's linguistic affiliation" (standard phonemes vs. spoken phonemes), phoneme position (initial vs. final), and linguistic context (singleton vs. cluster). Two groups of children speaking two different vernaculars were tested. The two vernaculars…

Diglossia, or the use of two forms of a language in a single speech community, is widespread. Differences between the nonstandard form, used for everyday conversations, and the standard form, used for formal occasions and writing, often extend to phonology as well as grammar and vocabulary. Most preschoolers from diglossic families are routinely…
