Summary
Speech-language pathologists can effectively identify velopharyngeal incompetence. Training in a scoring system significantly improved their perceptual evaluations, correlating well with expert and instrumental assessments.
Area of Science:
- Speech-language pathology
- Clinical audiology
- Pediatric medicine
Background:
- Velopharyngeal incompetence (VPI) affects speech intelligibility.
- Accurate diagnosis of VPI is crucial for effective treatment.
- Perceptual speech evaluation is a primary diagnostic tool.
Purpose of the Study:
- To assess the efficacy of perceptual speech evaluation in identifying velopharyngeal incompetence.
- To determine if orientation to a standardized scoring system improves diagnostic accuracy.
- To compare speech-language pathologists' (SLPs) evaluations with expert and instrumental assessments.
Main Methods:
- Eight school-based SLPs evaluated 24 subjects' speech samples for VPI.
- Evaluations were conducted before and after orientation to a VPI scoring system.
- Results were compared to live expert evaluations and instrumental data (telefluorography, manometry, pressure-flow).
Main Results:
- SLPs' evaluations significantly improved after orientation to the scoring system.
- Post-orientation evaluations showed strong correlation with expert live evaluations.
- SLP assessments aligned well with instrumental VPI diagnostic data.
Conclusions:
- SLPs possess the necessary skills to identify VPI through perceptual speech analysis.
- Formal training enhances the accuracy of SLPs' VPI estimations.
- Perceptual evaluation, when guided by a systematic approach, is a reliable method for VPI assessment.
