Nine trained listeners responded to tests of electrical analogs of the nasal and vocal tracts used to simulate the articulation of 3 nasal consonants of American English. Outputs of the consonant-involved configurations of the analog are distinguishable one from the other with minor inconsistencies in the data. 65% of the bilabial stimuli were identified as M. The results of determining whether listeners can distinguish the difference between M and N and NG compare fairly well to studies of listeners to human nasal consonants produced in isolation and in syllables.
