The accuracy of traditional articulatory descriptions of /s/ productions by normal and lisping speakers was tested. Three groups of children (normal speakers, frontal lispers, and lateral lispers) provided recordings of tongue pressures against the alveolar ridge while saying syllables containing /s/ and /z/. Two patterns of tongue contact were found for frontal lispers: one like that of normal speakers and another like that of lateral lispers. Lateral lispers uniformly provided deviant midline measure. The age of the subjects and position of the consonant in the syllable had little effect upon tongue contact and pressure. Males, however, did exhibit greater pressure. Tongue pressures during swallowing by the lisping groups were deviant from those of normal speakers.
