The influence of oral cavity tumour treatment on the voice quality and on fundamental frequency

Abstract

This study aimed to discover whether the surgical treatment of oral cavity tumours only affects on articulation or whether it also leads to a change in voice quality and fundamental frequency. Twelve participants were examined pre‐ and postoperatively for mean speaking fundamental frequency, standard deviation of the mean fundamental frequency, harmonic‐to‐noise‐ratio and intrinsic pitch. All the parameters showed a substantial postoperative change in some patients.

• Fundamental frequency
• voice quality
• oral cavity tumour
