Abstract | The aim of this study was to investigate the effectiveness of feedback on the learning of a
novel speech task: simulating hypernasality. Forty participants (20 male, 20 female; age
range 18-35 years) were randomly assigned into four groups, receiving different
combinations of feedback type (visual or verbal) and relative frequency of knowledge of
results (100% or 50%). The participants practiced hypernasal production of syllables, words
and a passage during acquisition. Their performances at baseline, immediate retention,
delayed retention and transfer were assessed with three different types of connected speech
stimuli. The results showed that learning was took place in all feedback conditions. However,
no significant difference was found across different feedback type and feedback frequency.
The findings indicated that velopharyngeal closure during speech can be controlled
voluntarily upon practice with appropriate feedback rendered. The findings also shed light
on the treatment of hypernasality and on speech motor learning. |
