The Primordial Echoes of Language

*This preprint presents the Opening Chapter (Chapter 0) of the forthcoming monograph Vọng Âm Nguyên Thủy (The Primordial Echoes of Language). The chapter explores the symbolic and cognitive origins of primordial sound, situating early human vocal emergence within a mytho-scientific framework that integrates ecology, perception, and cosmological imagination. Rather than adhering to conventional linguistic or archaeological models, this work adopts a scientific–literary approach, treating sound as a formative interface between biology, environment, and meaning. This chapter-level preprint is released to preserve intellectual priority and to allow early academic dialogue prior to the complete publication of the monograph.*
