verbaliser

Verbaliser, British English spelling for the American term verbalizer, has several related senses in English. It can denote a person who expresses thoughts verbally, articulating ideas, opinions, or internal reflections in spoken or written form. It can also refer to a device, method, or software that renders nonverbal information into verbal language or text.

In psychology and education, a verbaliser may describe someone who tends to verbalize their thoughts during problem solving or learning tasks. Think-aloud protocols, for example, treat participants as verbalisers by asking them to articulate their reasoning as they work through a task. In linguistics and cognitive science, the term can describe processes that convert mental representations into spoken or written language.

In computing and artificial intelligence, a verbaliser is a component or module within natural language generation systems that translates structured data, rules, or templates into coherent natural language outputs. Such verbalisation is common in automated reporting, dashboards, and data-to-text applications, where non-linguistic data must be made readable and actionable for humans.

Etymology derives from verbum, meaning word, with the agentive suffix -iser in British usage (or -izer in American English). The noun forms verbalisation and verbalization are used across modalities to describe the act or process of turning thoughts or data into words. Related terms include verbalization, think-aloud protocol, and speech synthesis.
