Enhancement of the perceptual encoding of talker characteristics (indexical information) in speech can facilitate listeners' recognition of linguistic content. The present study explored this indexical-linguistic relationship in nonnative speech processing by examining listeners' performance on two tasks: nonnative accent categorization and nonnative speech-in-noise recognition. Results indicated substantial variability across listeners in their performance on both the accent categorization and nonnative speech recognition tasks. Moreover, listeners' accent categorization performance correlated with their nonnative speech-in-noise recognition performance. These results suggest that having more robust indexical representations for nonnative accents may allow listeners to more accurately recognize the linguistic content of nonnative speech.

Acquisition of Speech Prosody in a Non-native Tone Language by Children With and Without Autism Spectrum Disorder.
J Autism Dev Disord
January 2025
The First Hospital of Jinan University, Guangzhou, China.
Purpose: Children with autism spectrum disorder (ASD) often show abnormal speech prosody. Tonal languages can pose more difficulties as speakers need to use acoustic cues to make lexical contrasts while encoding the focal function, but the acquisition of speech prosody of non-native languages, especially tonal languages has rarely been investigated.
Methods: This study aims to fill in the aforementioned gap by studying prosodic focus-marking in Mandarin by native Cantonese-speaking children with ASD (n = 25), in comparison with their typically developing (TD) peers (n = 20) and native Mandarin-speaking children (n = 20).
Effects of Language Proficiency on Selective Attention Patterns at Segmenting Boundaries in English Audio Sentences.
Brain Sci

School of Foreign Languages, Hunan University, Lushannan Road No. 2, Yuelu District, Changsha 410082, China.
Background/objectives: Normative perceptual segmentation facilitates event perception, comprehension, and memory. Given that native English listeners' normative perceptual segmentation of English speech streams coexists with a highly selective attention pattern at segmentation boundaries, it is significant to test whether Chinese learners of English have a different attention pattern at boundaries, thereby checking whether they perform a normative segmentation.
Methods: Thirty Chinese learners of English with relatively higher language proficiency (CLH) and 26 with relatively lower language proficiency (CLL) listened to a series of English audio sentences.
Background: Language difficulties are common in autism spectrum disorder (ASD), a neurodevelopmental condition characterized by impairments in social communication as well as restricted and repetitive behaviors. Amongst infant siblings of children with an ASD diagnosis - who are at higher likelihood for developing ASD - a high proportion also show difficulties and delays in language acquisition.
Methods: In this study, we used functional magnetic resonance imaging (fMRI) to examine atypicalities associated with language processing in 9-month-old infants at high (HL) and typical (TL) familial likelihood for ASD.
Early influence of language experience in non-native speech perception: Discrimination of three-way Thai stop contrasts by Korean and Japanese infants.
Infant Behav Dev
December 2024
RIKEN Center for Brain Science, Japan; Waseda University, Japan; Duke University, USA.
Article Synopsis
- Young infants initially can differentiate sounds from various languages, supporting the perceptual narrowing hypothesis, which suggests they become less sensitive to non-native phonemes as they grow.
- This study investigated how 4-6 month-old Korean and Japanese infants respond to specific Thai phoneme contrasts, specifically looking at their ability to discriminate between different stop sounds based on voice onset time (VOT).
- Findings revealed that Korean infants were sensitive to the pre-voiced vs. voiceless contrast, while Japanese infants were better at distinguishing the voiceless vs. voiceless aspirated sounds, highlighting significant differences in language input's impact on infants' phoneme discrimination abilities.
Effects of speaking style and semantic predictability on vowel production.
J Acoust Soc Am
November 2024
Department of Linguistics, Ohio State University, Columbus, Ohio 43210, USA.
Listener-oriented accounts of phonetic enhancement propose that talkers produce enhanced vowels to increase clarity when their interlocutor might experience communicative difficulty, e.g., for non-native interlocutors or for an unpredictable word given the semantic context.
