Nasalance is an important measure in speech pathology. In situations where velopharyngeal competence is in question, nasometry objectively documents the nasal component of speech as normal, hypemasal or hyponasal. It has been found to be of tremendous benefit in the management of patients with cleft palate and velopharyngeal incompetence. The subject is relaxed, and is fitted with a headgear apparatus. This apparatus is placed such that a plate lies in a horizontal plane that rests midway between the nose and the mouth. There are microphones on the upper and lower surfaces of the plate that capture sound energy produced from the nasal and oral cavities respectively. The subject is then asked to read standard passages. The three most commonly used passages are described here, and will be used in our study. The 'Rainbow' passage is most representative of standard English speech. The 'Zoo' passage has no nasal consonants, and the 'Nasal' passage has the highest number of nasal consonants.
