Bottom Line
This theoretical review proposes an integrative model explaining how speaker identity influences language comprehension through bottom-up acoustic-episodic processes and top-down expectation-based mechanisms. While the framework offers a comprehensive multi-level approach distinguishing between individual familiarity effects and social group expectations, it lacks empirical validation and systematic methodology. The model's clinical relevance is primarily theoretical, potentially informing speech-language pathology assessment and intervention strategies. However, the absence of testable predictions and limited consideration of contradictory evidence weakens its immediate practical utility. Future empirical studies are needed to validate the proposed mechanisms and establish clinical applications, particularly in language development assessment and social cognition evaluation.

Abstract
The identity of a speaker influences language comprehension through modulating perception and expectation. This review explores speaker effects and proposes an integrative model of language and speaker processing that integrates distinct mechanistic perspectives. We argue that speaker effects arise from the interplay between bottom-up perception-based processes, driven by acoustic-episodic memory, and top-down expectation-based processes, driven by a speaker model. We show that language and speaker processing are functionally integrated through multi-level probabilistic processing: prior beliefs about a speaker modulate language processing at the phonetic, lexical, and semantic levels, while the unfolding speech and message continuously update the speaker model, refining broad demographic priors into precise individualized representations. Within this framework, we distinguish between speaker-idiosyncrasy effects arising from familiarity with an individual and speaker-demographics effects arising from social group expectations. We discuss how speaker effects serve as indices for assessing language development and social cognition, and we encourage future research to extend these findings to the emerging domain of artificial intelligence (AI) speakers, as AI agents represent a new class of social interlocutors that are transforming the way we engage in communication.
