The speech samples consisted of isolated vowels (/a/, /i/, /u/), ten words with high pressure consonants, and five standard oral sentences. In the lab, the individuals were instructed to sit in upright positions while they had a substance instilled in the nasopharynx for better visualization of the contrast. The participants were asked to read the white sheet of paper with images that were amplified by an electric intensification, brightening the images recorded in the video camera. These images were then evaluated by three speech language pathologists by rating the pictures on a scale for videofluroscopic speech studies. The rating scale evaluated the structural and functional aspects of velopharyngeal mechanism which included velopharyngeal closure, velar length, velar thickness, height of the velum, and tongue motion. Each speech language pathologist who participated in the study were blindfolded and asked to rate the video samples based on the rating scale of velopharyngeal closure, velar length, velar thickness, height of the velum, and tongue
