The short-time articulation index.
James Mitchell Kates · PubMed · 1987
In this paper we introduce the concept of the short-time articulation index. This is a procedure for calculating a time-varying articulation index from data on a block-by-block basis. The short-time articulation index can be used to give a running measure of the speech intelligibility for an adaptive noise-cancellation system as it converges. We present an algorithm for calculating the short-time articulation index and give some examples of its use.
