Summary

Vocal Profile Analysis aids speech therapy for ventilator-dependent children. Speaking aids improve communication, especially in those with intact cognitive function and developed speech.

Area of Science:

  • Speech-Language Pathology
  • Pediatric Medicine
  • Biomedical Engineering

Background:

  • Effective communication is crucial for ventilator-dependent children's societal reintegration.
  • Speaking aids are vital tools for enhancing verbal skills in this population.

Purpose of the Study:

  • To evaluate the utility of Vocal Profile Analysis (VPA) for assessing voice quality in ventilator-dependent children using speaking aids.
  • To determine if VPA can guide speech therapy interventions for improved communication.

Main Methods:

  • A perceptual rating scale was used to evaluate vocal function in four ventilator-dependent children using the Passy-Muir Tracheostomy Speaking Valve.
  • Three speech therapists, blinded to diagnoses, independently assessed children at varying developmental and cognitive stages.

Main Results:

  • Speaking aids improved verbal communication, though speech abnormalities persisted in most children.
  • Observer agreement was higher when assessing children with intact cognitive function.
  • An older child with intact cognition demonstrated near-normal speech potential with the speaking valve.

Conclusions:

  • Vocal Profile Analysis is effective for assessing vocal characteristics in ventilator-dependent children with intact cognition.
  • Achieving near-normal speech with speaking aids is possible, contingent upon developmental speech stage.
