Summary
Worse voice detection thresholds in children with cochlear implants correlate with higher voice frequency in sustained vowels and spontaneous speech. This finding is crucial for understanding speech characteristics in this population.
Area of Science:
- Audiology
- Speech-Language Pathology
- Pediatric Otolaryngology
Background:
- Hearing impairment significantly affects voice quality, articulation, and resonance.
- Understanding factors influencing voice in cochlear implant (CI) users is vital for rehabilitation and clinical practice.
Purpose of the Study:
- To investigate the relationship between demographic and audiological factors and voice acoustics in pediatric CI users.
- Specifically, to correlate age, device use duration, voice detection threshold, and hearing/language scores with acoustic voice parameters.
Main Methods:
- Retrospective analysis of 51 children (3-5 years 11 months) with unilateral CI.
- Acoustic analysis of sustained vowel /a/, sequential, and spontaneous speech.
- Correlation of acoustic data with demographic and hearing test results.
Main Results:
- A significant correlation was found between a poorer voice detection threshold and higher voice frequency.
- This association was observed in both sustained vowel /a/ production (p≤0.001) and spontaneous speech (p≤0.005).
Conclusions:
- Voice detection threshold is a significant correlate of voice frequency in children using cochlear implants.
- These findings highlight the importance of audiological measures in understanding voice production in this population.
