Lagjeve

Lagjeve is a fictional term used in theoretical discussions of speech timing and dialogue coordination. It denotes a transient latency in which there is a measurable gap between a speaker's planned utterance and its acoustic realization during fluent conversation. In this model, lagjeve is not a fixed property of the speaker but a variable influenced by discourse context, cognitive load, and social signaling. It is typically quantified as the time difference between the completion of a linguistic plan (T_plan) and the onset of audible articulation (T_art).

The term is a neologism created to illustrate how micro-delays can affect turn-taking, backchanneling, and repair; early discussions used it to separate planning lag from other delays such as hesitation or motor latency. In practice, researchers employing lagjeve frameworks might combine speech timing data with behavioral cues like gaze and gesture, to infer hidden planning states. Critics argue that the model risks conflating cognitive delay with communicative strategy. Proponents say it helps formalize observations of asynchronous planning during rapid dialogue.

Because lagjeve is fictional, no standard measurement protocol exists; any implementation relies on the specific research design. Related concepts include turn-taking, speech planning, processing latency, and human-computer interaction delay.
