Articulatory Adaptation Following Oral Cancer Treatment


The goal of this longitudinal study is to learn more about the articulatory consequences of surgical oral cancer treatment. The main aims are to study the coordination and development of speech articulation of patients who will undergo surgical treatment for oral cancer longitudinally and whether individual differences in the reliance on auditory or tactile information can predict the success of speech compensatory strategies. Participants will perform multiple speech tasks while motion tracking sensors track the articulatory gestures.

Study Type

  • Study Type: Observational
  • Study Design
    • Time Perspective: Prospective
  • Study Primary Completion Date: August 2024


  • Other: Electromagnetic Articulography
    • Motion tracking sensors will track articulatory movements of the tongue, jaw and lips

Arms, Groups and Cohorts

  • Individuals treated for oral cancer
    • Dutch native speakers (18+) who will undergo surgical treatment for a T1 or T2 tumour on the tongue.
  • Control speakers
    • Dutch native speakers (18+) without self-reported speech problems.

Clinical Trial Outcome Measures

Primary Measures

  • Articulatory gestures
    • Time Frame: 2022-2025
    • Articularory movements in three dimensions of the tongue, lips and jaw
