Insights
Palatal obturators did not significantly improve consonant production in babies with cleft palate during babbling. Further research is needed to explore potential benefits for speech development in infants with unrepaired cleft palate.
Area of Science:
- Speech-language pathology
- Pediatric audiology
- Craniofacial anomalies
Background:
- Babbling is a crucial stage for speech sound development.
- Cleft palate can impede normal articulation development.
- Palatal obturators are devices used to manage cleft palate effects.
Purpose of the Study:
- To investigate the effect of palatal obturators on consonant development during babbling in infants with unrepaired cleft palate.
- To determine if obturator use influences consonant inventory size, place, and manner of production.
Main Methods:
- A matched-pairs study design was employed.
- Fourteen infants with cleft palate using obturators were compared to 14 non-obturator users.
- Spontaneous vocalizations were analyzed for consonant production characteristics.
Main Results:
- No significant differences were found in consonant inventory size between obturator and non-obturator groups.
- No significant differences were observed in the place and manner of consonant production.
- A trend suggested more glottal consonant production in the obturator group.
Conclusions:
- Palatal obturators do not appear to enhance the production of anterior palatal consonants during babbling in infants with cleft palate.
- The findings suggest obturators may not facilitate early speech sound acquisition in this population.
- Further investigation into the role of obturators in speech development is warranted.
Objective:
The purpose of this investigation was to determine whether palatal obturators enhance consonant development during babbling for babies with unrepaired cleft palate.
Participants:
Fourteen babies with cleft palate who had worn anterior palatal obturators prior to palatal surgery were matched to 14 unobturated babies according to cleft type, sex, and age at time of presurgical evaluation.
Main Outcome Measures:
Spontaneous vocalizations of the obturated and unobturated groups were compared to determine whether differences were evident in size of consonant inventory as well as place and manner of consonant production.
Results:
Paired t tests revealed no significant differences between the groups in size of consonant inventory or place and manner of consonant production. There was a trend for babies in the obturated group to produce more glottal consonants.
Conclusions:
In general, the findings of this study suggested that palatal obturators do not appear to facilitate production of anterior palatal consonants during babbling.
