- Abstract
Prior research has extensively explored audiovisual speech perception and literacy skills in various linguistic contexts. Studies have shown that children's ability to integrate auditory and visual speech cues plays a crucial role in language acquisition and development (Erdener & Burnham, 2013; Lalonde & Werner, 2021). Furthermore, research highlights the importance of visual speech cues for phonological awareness and reading skills (Erdener & Burnham, 2013; Burnham, 2003). However, much of this research has been conducted within English and Indo-European language contexts (Kidd & Gracia, 2022; Share 2008), potentially limiting the generalizability of current language and literacy theories to a broader range of languages and linguistic contexts. Hence, this study aims to advance our comprehension of language and literacy development by investigating the connections between bilingualism, multimodal speech perception, and reading proficiency in the context of Uzbekistan. This research focuses on Uzbek and Russian languages, which have received comparatively less scholarly attention, thus offering a unique opportunity to enrich existing knowledge on language acquisition and literacy in diverse linguistic settings. The first study focusing on audiovisual speech perception skills in monolingual and bilinguals found that bilingualism did not significantly impact audiovisual speech perception and that the degree of cross-linguistic similarity between languages might influence the extent of reliance on visual speech cues in bilingual children, highlighting the importance of considering language-specific factors in audiovisual speech perception. The second study delved into how reading skills predict sensitivity to audiovisual and auditory speech cues, showing that reading skills predict heightened sensitivity to both audiovisual and auditory speech cues in the context of languages with transparent orthographies. The third study revealed that bilingual individuals demonstrate a reading advantage when tested in instructional languages but not in noninstructional languages; this study also showed the bidirectional cross-linguistic transfer of literacy skills across languages is possible, regardless of writing script differences. Overall, these studies collectively broaden our understanding of language acquisition and literacy development, emphasizing the significance of linguistic diversity, crosslinguistic similarities, and contextual factors in shaping children's language and literacy development.
