Following ARTICULATION 41 an in-depth review of this work, the data will be modeled using the tools of the articulation index, using parallel and sequential models. The articulation index theory was developed by the telephone company, for network characterization. 9 Bell Labs was asked to participate in solving these communications problems, so Fletcher and his team went to Harvard to provide support. This meeting, of 31 people at Harvard on June 19, 1942, is documented in Galt’s sixteenth notebook, starting on page 158 (Rankovic and Allen, 2000), and in the personal notes of Stevens about this meeting (Rankovic, personal communication).

Merging the formula for the band errors Eq. 12) with that for the specific AI Eq. 16), the total error may be related to the average specific AI, Eq. 13), via Eq. 14), leading to e = e 1 e 2 · · · e K = e min AI1 /K e min AI2 /K · · · e min AI K /K = e min AI . 17) 36 ARTICULATION AND INTELLIGIBILITY Since s = 1 − e , Eq. 10) follows, as required.
