RESUMO

Speech hypernasality is a nasal resonance’s disorder, come across often in cleft palate persons with velopharingeal disfuction. It is an inappropriate and excessive nasality just oral sounds, that can be analyzed for spectrograph (decompose speech signal in three dimensions: frequency, time and intensity, generating the spectrogram). Hence, this dissertation has the objective of investigating speech hipernasality spectrographic cues of the cleft palate women and to compare the findings with the nasometry results and auditory perceptual evaluation of the speech issues. Thirty women without speech and of the vocal tract problems, 5 cleft palate women no operated and 21 operated (18 to 40 years old) issues [a] and nasal, isolated and within of the carrier phrase in front of the nasometer and digital record. After auditory perceptual evaluation, nasalances and formants cues it was possible to verify nasal formants and antiformants among oral formants in the nasalized/hipernasalyzed issues and don´t have correspondency this findings with the nasometry neither with the auditory perceptual evaluation neither themselves
