Speakers adapted their tongue movements after partial glossectomy, shifting articulation points to maintain sound quality. This research shows compensatory articulation can produce intelligible speech despite significant lingual changes.

Area of Science:

  • Speech Science
  • Linguistics
  • Surgical Outcomes

Background:

  • Partial glossectomy significantly alters lingual morphology, impacting speech production.
  • Understanding compensatory articulation is crucial for speech rehabilitation after tongue surgery.

Purpose of the Study:

  • To investigate how speakers adjust articulation after partial glossectomy.
  • To determine if specific articulatory features are maintained.
  • To assess the intelligibility of speech produced with compensatory gestures.

Main Methods:

  • Acoustic and kinematic analysis of speech in three partial glossectomy patients.
  • Examination of changes in place and manner of articulation.
  • Correlation of articulatory changes with speech intelligibility.

Main Results:

  • Speakers shifted articulation to match altered tongue shape.
  • Key articulatory features, like sibilant groove width, were preserved.
  • Compensatory gestures resulted in perceptually acceptable substitute sounds.

Conclusions:

  • Post-glossectomy speech adaptation involves relocating articulation points.
  • Preservation of certain articulatory metrics aids intelligibility.
  • Transposed articulatory gestures can lead to successful speech compensation.
