High fidelity tape recordings were made of the cries of 8 babies with cleft palates and 8 babies with normal palates. Their ages ranged from 3 mo. to 24 mo. The 16 original tapes were recorded on a test tape in a counterbalanced order and were classified by 5 speech clinicians as to whether the cries were those of cleft palate babies. If the clinicians classified a cry as being that of a cleft palate baby, they were also to indicate if the cry was from a unilateral cleft lip/palate baby, a bilateral cleft lip/palate baby, or a baby with a cleft palate and no cleft lip. Spectrograms were also made of each of the 16 cries, with an overlay technique being used for the analysis.
