Purpose: Facial transplantation involves partial or total replacement of neuromuscular and skeletal structures of the face, head, and neck using donor tissues and is among the most extensive facial reconstructive procedures. This case report compares changes in speech production and articulator movement in a 44-year-old man from pretransplant to a…

Purpose: The aim of this study is to determine the effect of background noise on the intelligibility of dysphonic speech and to examine the relationship between intelligibility in noise and an acoustic measure of dysphonia--cepstral peak prominence (CPP). Method: A study of speech perception was conducted using speech samples from 6 adult speakers…

Purpose: We documented speech and voice characteristics associated with oculopharyngeal muscular dystrophy (OPMD). Although it is a rare disease, OPMD offers the opportunity to study the impact of myopathic weakness on speech production in the absence of neurologic deficits in a relatively homogeneous group of speakers. Methods: Twelve individuals…

Purpose: This study evaluated the effects of noise and speech intelligibility on the processing of speech produced from native English; high-intelligibility, Korean-accented English; and moderate-intelligibility, Korean-accented English speakers. Method: Both listener comprehension, determined by accuracy judgment on true/false sentences, and…

Much of speech perception research has focused on brief spectro-temporal properties in the signal, but some studies have shown that adults can recover linguistic form when those properties are absent. In this experiment, 7-year-old English-speaking children demonstrated adultlike abilities to understand speech when only sine waves (SWs)…

PURPOSE: To determine empirically which of three frequently observed rules in children with phonological disorders contributes most to difficulties in speaker intelligibility. METHOD: To evaluate the relative effects on intelligibility of deletion of final consonants (DFC), stopping of fricatives and affricates (SFA), and fronting of velars (FV),…

This study compares the ability of 37 Standard-English-speaking graduate students to comprehend Black English versions of a set of 45 utterances with the ability of 37 comparable students to comprehend Standard English versions of the same utterances. Of the two stimulus tapes used (consisting of 45 sentences each), one was recorded in Black…
