Articulation score

In telecommunications, an articulation score (AS) is a subjective measure of the intelligibility of a voice system in terms of the percentage of words correctly understood over a channel perturbed by interference.{{cite book |last1=Allen |first1=J.

Articulation scores have been experimentally obtained as functions of varying word content, bandwidth, audio signal-to-noise ratio and the experience of the talkers and listeners involved.{{Citation needed|date=March 2025}}
