This study involved an acoustic and perceptual analysis of the speech produced by a 31-year-old female following total glossectomy. Speech samples were collected on three occasions within the first 3 months following glossectomy. Vowel articulation was examined acoustically as a function of vowel space and the Euclidean distance separating corner vowels. Perceptual analyses involved presentation of the participant's CV productions to 30 healthy adult listeners who made forced-choice identifications of consonant type. Acoustic analysis revealed improvements in vowel space area and an increase in the Euclidean distances. The perceptual results revealed a statistically significant deterioration in consonants over the 3-month period with anterior sounds being perceived more correctly than medial and posterior sounds. The current study highlights the variable nature of speech following glossectomy, with greater improvements in vowel articulation compared to consonant articulation during the earliest stages of surgical recovery.
