The effect on speech presents as compensatory articulation, hypernasality
, nasal air leakage, weak intraoral pressure, and nasal turbulence (13).
can be suspected if airflow is identified in stimuli that contain oral + vowel combinations (papapa, tatata, kakaka, sasasa, sasasa) in the straw test.
Effectiveness of Lee Silverman Voice Treatment (lsvt) on hypernasality
in non-progressive dysarthria: the need for further research.
Patients with palatal fistula commonly present with nasal regurgitation of fluid and food, hypernasality
, mouth odour, hearing problems and psychological issues.
Her speech had imprecise articulation and hypernasality
. Her neurological examination, routine blood tests, thyroid function tests, liver function tests, and computed tomography (CT) of the brain were all within normal limits.
Although the results of a number of subjective studies that used auditory perception to measure nasality found that UPPP does not result in nasality changes, (3,4,7,8) one subjective study did find that transient hypernasality
occurred in patients during the first 10 days after UPPP and that hypernasality
that persisted for more than 6 weeks after surgery was associated with wound healing and was self-limiting.
Notably, 93% of the cases reported negative margins and the surgical complication rate was 19%, with complications including mucosal hemorrhage, tracheotomy, trismus, and hypernasality
. All patients had a PEG tube placed, but 96% recovered normal swallowing function at follow-up.
Kuehn, "The effect of articulatory adjustment on reducing hypernasality
," Journal of Speech, Language, and Hearing Research, vol.
When the velopharyngeal port is opened, even partially, when it should be closed for non-nasal phonemes, we say there is hypernasality
. When the velopharyngeal port is closed, even partially, for nasal phonemes, we say there is hyponasality.
In terms of speech intelligibility, hyponasality is preferred over hypernasality
. The idea that many cleft palate patients with VPI often had good lateral wall movement allowing a "tailored width" pharyngeal flap  was also not yet widely known.
These neuromuscular alterations translate into a slow speech rate, an excessive and equitable stress for all the syllables of the word, imprecise articulation, vocal distortion, hypernasality
, reductions in stress, use of short sentences, small variations in pitch and intensity, breaks in pitch, aggravated tone and hoarse, strained and strangled voice (Darley et al., 1969a, 1969b, 1975).
, a breathy vocal quality and a reduced rate of speech were noted.
