The acoustic realization of language-specific phonological categories despite dynamic cross-linguistic influence in bilingual and trilingual speech.

The present study examines the acoustic realization of the English, Japanese, and Spanish /k/ in the productions of two groups of English-Japanese bilinguals [first language (L1) English-second language (L2) Japanese and L1 Japanese-L2 English] and one trilingual group [L1 Spanish-L2 English-third language (L3) Japanese]. With the analysis of voice onset time (VOT) as a proxy for the degree of cross-linguistic influence in each language, this experiment compares the production patterns of L2 and L3 learners of Japanese and explores the effects of language mode and cognate status on the speech patterns in each of the languages of these bilingual and trilingual individuals. By manipulating the degree of activation of the target and non-target language(s) with the use of cognates and non-cognates in monolingual, bilingual, and trilingual experimental sessions, this study investigates static as well as transient phonetic influence.

Cross-Linguistic Influence in the Bilingual Mental Lexicon: Evidence of Cognate Effects in the Phonetic Production and Processing of a Vowel Contrast.

The present study examines cognate effects in the phonetic production and processing of the Catalan back mid-vowel contrast (/o/-/ɔ/) by 24 early and highly proficient Spanish-Catalan bilinguals in Majorca (Spain). Participants completed a picture-naming task and a forced-choice lexical decision task in which they were presented with either words (e.g.

The Effects of Language Dominance in the Perception and Production of the Galician Mid Vowel Contrasts.

Aims: This study investigates the perception and production of the Galician mid vowel contrasts by 54 early Spanish-Galician bilinguals in the cities of Vigo and Santiago (Galicia, Spain). Empirical data is provided to examine the role of language dominance in the perception and production of Galician mid vowel contrasts in order to determine whether the Galician vowel system is becoming more Spanish-like as a result of extensive contact with Spanish in urban areas.

Methods: Perception and production data for each mid vowel contrast were collected in (1) binary forced-choice identification tasks, (2) AX discrimination tasks and (3) a reading-aloud task.
