Abstract: Surgical treatment for tongue cancer can negatively affect the mobility and musculature of the tongue, which can influence articulatory clarity and variability. In this study, we investigated articulatory clarity through the vowel articulation index (VAI) and variability through vowel formant dispersion (VFD). Using a sentence reading task, we assessed 11 individuals pre and six months post tongue cancer surgery, alongside 11 sex- and age-matched typical speakers. Our results show that while the VAI was significantly smaller post-surgery compared to pre-surgery, there was no significant difference between patients and typical speakers at either time point. Post-surgery, speakers had higher VFD values for /i/ compared to pre-surgery and typical speakers, signalling higher variability. Taken together, our results suggest that while articulatory clarity remained within typical ranges following surgery for tongue cancer for the speakers in our study, articulatory variability increased.
