This study examines the digitalization of Nigerian languages through the development of innovation models that integrate language teaching,localization,community-based knowledge production, and technological support. Adopting a qualitative research design and a thematic analysis of existing literature, the study identifies key patterns shaping the digital transformation of indigenous languages.The findings indicate that digital tools contribute to improved language teaching, localization enhances accessibility, and community participation supports the preservation and continued relevance of these languages. However, these efforts remain largely fragmented, limiting their overall effectiveness and scalability. While emerging technologies, particularly artificial intelligence, present new opportunities for language development, their application is constrained by the low-resource nature of many Nigerian languages.The study therefore proposes an integrated innovation model that aligns educational practices, technological development, and community engagement within a unified framework. It concludes that the sustainable digitalization of Nigerian languages requires a coordinated socio-technical approach capable of positioning these languages as active mediums of knowledge production in digital environments
