Reply to: “Reliability and Validity of Speech Evaluation in Adductor Spasmodic Dysphonia; Common Mistake and Statistical Issues” by Saori Yanagida

We thank Dr. Sabour for his interest in our article "Reliability and validity of speech evaluation in adductor spasmodic dysphonia."1 In this research, Pearson correlation coefficient was obtained for the purpose of evaluating the intra- and interrater or intra- and intermeasurer reliabilities for perceptual evaluation and acoustic measures. As Dr. Sabour pointed out, calculation of the intraclass correlation coefficient (ICC) showed there was almost no difference between that value and Pearson correlation coefficient (Tables 1, 2).
