The relationship between nasalance and nasality in children with cleft palate.

This study correlated measures of nasalance computed by the Nasometer with listener judgments of nasality. The subjects were 25 children with craniofacial disorders who spoke three passages, each containing a different proportion of nasal consonants. The results showed a significant but modest correlation between nasalance and nasality when nasal consonants (/m, n, eta/) were not included in the speech passage. When nasal consonants were included in the passage nasalance was unrelated to judgments of hypernasality.
