Article Abstract
Introduction: This study investigates the cognitive consequences of bilingualism by examining phonetic learning, speech motor adaptation, and verbal memory.
Methods: Early Spanish-English bilinguals divided into high and intermediate proficiency groups and English monolinguals completed three tasks: (1) production of an artificial English accent with novel phonotactic rules, (2) serial digit span in English, and (3) production of unfamiliar speech sounds during real-time magnetic resonance imaging (rtMRI).
Results: Bilinguals, particularly those with high proficiency, outperformed monolinguals in phonetic and articulatory learning. In the memory task, no group-level differences emerged overall, but high bilinguals showed stronger primacy effects at moderate sequence lengths, suggesting more efficient encoding.
Discussion: These results support a shift toward investigating task-specific and process-based effects of language experience. We also demonstrate the feasibility of using rtMRI to assess articulatory behavior in cognitive studies of bilingualism, with minimal need for manual post-processing.

In the Words of Others: ERP Evidence of Speaker-Specific Phonological Prediction.

Prediction models usually assume that highly constraining contexts allow the pre-activation of phonological information. However, the evidence for phonological prediction is mixed and controversial. In this study, we implement a paradigm that capitalizes on the phonological errors produced by L2 speakers to investigate whether specific phonological predictions are made based on speaker identity.

While much work has emphasized the role of the environment in language learning, research equally reports consistent effects of the child's knowledge, in particular, the words known to individual children, in steering further lexical development. Much of this work is based on cross-sectional data, assuming that the words typically known to children at n months predict the words typically known to children at n+x months. Given acknowledged variability in the number of words known to individual children at different ages, a more conclusive analysis of this issue requires examination of individual differences in the words learned by individual children across development, that is, using longitudinal data.

The speech recognition task of the HaiNan dialect faces significant differences in phonology, intonation, and grammatical structure among dialects, which in turn show significant regionalization characteristics, which makes the task of dialect-to-Mandarin conversion more complex. Currently, the research on the HaiNan dialect speech recognition is still in its early stages and lacks sufficient corpus resources, especially in the task of multi-dialect recognition. Traditional models are difficult to solve with the problem of data scarcity and diverse dialect characteristics effectively.

At high fundamental frequencies (fos), wide harmonic spacing can obscure typical formant cues. This study investigates the role of static spectral cues in maintaining vowel identity under such conditions. We resynthesized steady-state versions of eight German vowels (/i, y, e, ø, ɛ, a, o, u/) across fos ranging from 220 to 880 Hz from previously identifiable spoken vowels, preserving their gross spectral shapes.

Listeners accommodate rampant variability in speech input, at least in part, by adapting to structured phonetic variation. However, most work demonstrating this type of perceptual learning has focused on group-level effects in modal populations. This approach masks potentially meaningful differences-present among all listeners but particularly associated with autism-in sensory perception, social functioning, and language processing.
