Processing Relationships Between Language-Being-Spoken and Other Speech Dimensions in Monolingual and Bilingual...

Area of Science:

• Psycholinguistics
• Cognitive Science
• Speech Processing

Background:

• Indexical information plays a crucial role in language processing.
• The internal structure of indexical dimensions, especially in bilinguals, remains underexplored.
• Understanding how bilinguals process multiple indexical cues is vital for cognitive and linguistic research.

Purpose of the Study:

• To investigate the integration of the "language-being-spoken" dimension with other speech features in processing.
• To examine how bilingual status and language experience influence the processing of indexical speech dimensions.
• To identify potential processing hierarchies among indexical and non-linguistic speech features.

Main Methods:

• Employed the speeded classification paradigm across three experiments.
• Compared the processing of "language-being-spoken" (Mandarin Chinese vs. English) with talker identity, talker gender, and speech amplitude.
• Assessed processing dependencies and interference asymmetries in relation to listeners' bilingual status.

Main Results:

• "Language-being-spoken" is consistently integrated with talker identity, gender, and amplitude during speech processing.
• These processing dependencies were observed irrespective of listeners' bilingual status or language proficiency.
• Significant processing interference asymmetries suggest a hierarchical organization of indexical and non-linguistic speech features.

Conclusions:

• The "language-being-spoken" cue is a fundamental aspect of speech processing, interacting with other indexical and non-linguistic features.
• Bilingualism does not fundamentally alter the integration of basic indexical speech dimensions.
• Speech perception involves a hierarchical system for processing various auditory and linguistic cues.
