Insights
Infants with stronger oromotor skills at 6 months produced more speech sounds and babbled earlier, suggesting a link between oral motor development and early speech abilities.
Area of Science:
- Developmental Pediatrics
- Speech-Language Pathology
- Infant Communication
Background:
- Early oromotor skills are crucial for feeding and speech development.
- Understanding the relationship between oromotor abilities and early speech milestones is important for identifying potential developmental delays.
Purpose of the Study:
- To investigate the association between infants' oromotor skills and the onset of babbling.
- To determine the relationship between oromotor proficiency and phonetic inventory at 6 months of age.
Main Methods:
- Parents of 50 six-month-old infants completed the Child Oral and Motor Proficiency Scale (ChOMPS).
- Caregivers reported on infant babbling and phonetic inventory (protophones) via an online questionnaire.
- Statistical analyses included linear and logistic regression.
Main Results:
- Higher ChOMPS scores were significantly associated with a larger number of reported protophones.
- Infants' ChOMPS scores significantly predicted the likelihood of babbling by 6 months.
- Preterm status and sex did not influence babbling onset or phonetic inventory.
Conclusions:
- Early oromotor development appears linked to emerging speech abilities in infants.
- Stronger oromotor skills at 6 months may indicate a larger protophone variety and earlier babbling.
- Oromotor behaviors could serve as early indicators of developing speech skills.
Aim:
This study aimed to determine whether infants' oromotor skills were related to the onset of babbling and their phonetic inventory at 6 months of age.
Methods:
Parents of 50 6-month-old infants (41 full-term, 9 preterm) completed the Child Oral and Motor Proficiency Scale (ChOMPS), a valid and reliable caregiver-report measure of oromotor, feeding, and gross motor development. Caregivers additionally reported information about their infant's babbling and perceived phonetic inventory, or protophones, via an online questionnaire.
Results:
Linear regression analysis revealed a statistically significant positive association between ChOMPS scores at 6 months and the number of different protophones parents reported that the infant produced. Logistic regression modelling showed that infants' ChOMPS scores significantly predicted their likelihood of babbling by 6 months of age. Preterm status and sex were not associated with babbling onset or phonetic inventory.
Conclusion:
These findings suggest a possible link between early oromotor development and emerging speech abilities in infancy. Infants with stronger oromotor skills at 6 months tended to produce a larger variety of protophones and were more likely to be early babblers, per parent report. These results reveal the potential value of early oromotor behaviours as indicators of developing speech skills.
