Etymology
The term "text-to-speech" is a modern English compound, formed in the late 20th century to describe a specific computational function. It is constructed transparently from three native English elements: "text," referring to written language; the preposition "to," indicating a directional conversion; and "speech," referring to audible spoken language. This compound follows a straightforward descriptive logic, naming the technology by its core action—transforming one form of language (written) into another (spoken). Its formation mirrors other directional compound terms in technology (e.g., analog-to-digital) and is purely functional, with no deeper historical evolution beyond the individual meanings of its constituent words.
