In the paper titled “Changes in Vowel Articulation with Subthalamic Nucleus Deep Brain Stimulation in Dysarthric Speakers with Parkinson’s Disease,” in Section 2.3.1, the authors cited incorrectly a study by Sapir and colleagues . The correct reference should have been “S. Sapir, L. O. Ramig, J. L. Spielman, and C. Fox, ‘Formant centralization ratio: a proposal for a new acoustic measure of dysarthric speech,’ Journal of Speech, Language and Hearing Research, vol. 53, no. 1, pp. 114–125, 2010. doi: 10.1044/1092-4388 (2009/08-0184).”
