Phonetic imitation is a ubiquitous process in speech production. Speakers have a strong tendency to imitate their interlocutors both in a native and a non-native language. It is especially important in acquiring non-native speech, because it allows forming new sound categories. In the current study we investigated whether and to what extent Polish…

Verbal morphology has been identified as a particularly vulnerable domain for adult heritage speakers (HSs) of Spanish, especially when it involves the selection of subjunctive mood. A minimal amount is known, however, about the potential effects of the variability associated with these forms on the acquisition of related epiphenomena, such as the…

This article presents an acoustic study of the acquisition of vowel formant dynamics in L2 (Southern British) English by Polish learners at two levels of proficiency, along with baseline data from L1 English and L1 Polish. Results from our experiment suggest that the acquisition of English vowels by Polish learners entails a temporal…

This article proposes that second language learners can use indirect positive evidence (IPE) to acquire a phonological grammar that is a subset of their L1 grammar. IPE is evidence from errors in the learner's L1 made by native speakers of the learner's L2. It has been assumed that subset grammars may be acquired using direct or indirect negative…
