Figure-based speech perception test: applicability in children with Down syndrome

To verify the applicability of the picture-based speech perception test in children with Down syndrome. Observational, descriptive, prospective study, carried out at two speech therapy centers, approved by their Research Ethics Committees under numbers 82522217.5.0000.5440 and 79510317.8.0000.5257. A total of 41 children with Down syndrome, of both sexes, aged 2 years to 10 years and 11 months participated. They were divided into three groups: GI (2 years to 4 years and 11 months); GII (5 years to 7 years and 11 months); GIII (8 years to 10 years and 11 months). We verified their medical history and carried out meatoscopy, pure-tone threshold audiometry, speech recognition threshold test with pictures, and immittance tests. For statistical analysis, we used Fisher's Exact Test with the 5% significance level. Results: The analysis of hits and misses in relation to chronological age revealed significance in seven words: "ice", "knife", "cow", "key", "mouse", "dog", and "sun". We then analyzed this study participants' performance in the speech test with pictures and those in the study that developed and validated this test. Comparing the percentage of correct answers in the two groups, we found that the words with the most correct answers were "hand", "house", and "frog". Conclusion: The test applied in this study provides a clear and objective interpretation of the results, regardless of the child's verbal production.
