Nature of the Test
For this assessment, our team used the Simplified Nasometric Assessment Procedure-Revised (SNAP-R). This test includes three subtests, but for the purpose of this project, we used the Picture-Cued Subtest. This subtest includes stimulus items that target bilabials, lingual-alveolar plosives, velar plosives, sibilants, and nasals. For each sound type, it contains three pictures and carrier phrases, which are each read twice to create a six-sentence passage. For example, for bilabials, the child will look at the screen and say, “Pick up the book. Pick up the pie. Pick up the baby.” twice. To measure this assessment, we used the Nasometer II Handheld Separator, which was calibrated to 1.0 at the beginning of the session. To …show more content…
Our participant’s mean for the bilabials was 7%, and the mean for the lingual-alveolars was 6%, which means that they are both slightly lower than the normative mean of 11% (for both bilabials and lingual-alveolars). Our participant’s mean of the velar sounds was 8%, which is also lower than the normative mean of 13%. The sibilants’ mean was 8%, which is consistent with the others by being lower than the normative mean of 12%. The participant’s mean for the nasal passage was 52%, which is slightly less than the normative mean of 54%. This shows that the inferred overall resonance was a typical resonance because it is within two standard deviations of the normative means (Kummer, 2005). The evidence that supports this inference is based upon the fact that P1 was within one standard deviation below the normative means for each of the passages. The linguistic unit that was used to assess the resonance of P1 was a passage. Furthermore, throughout the assessment, nasal emission was not noted due to the lack of airflow “released through the nose,” which would cause “a disruption in the aerodynamic process of speech” (Kummer, 2014, p. 190). These results appear to be consistent with the perceptual assessment. Each of the sound passages were considered normal speech by the clinicians, and this was further supported by the results of the
