Communication Efficiency in a Face Transplant Recipient: Determinants and Therapeutic Implications

We longitudinally assessed speech intelligibility (percent words correct/ pwc ), communication efficiency (intelligible words per minute/ iwpm ), temporal control markers (speech and pause coefficients of variation), and formant frequencies associated with lip motion in a 41-year-old face transplant recipient. Pwc and iwpm at 13 months post-transplantation were both higher than preoperative values. Multivariate regression demonstrated that...
