This paper focuses on various movements of the tongue in perturbed speech. In this experimental study, the activity of the jaw has been neutralized in order to observe the movements of tongue. Previous studies with bite blocks have shown that intelligibility can be maintained by producing unusual configurations of the vocal tract in order to compensate for the immobility of an articulator. We thus observed how spatial and temporal changes of the tongue configurations palliate the immobilization of the mandible. Results show that the presence of bite blocks modifies the duration and amplitude of articulatory movements. A repositioning of linguo-palatal contacts has also been observed. Results are speaker dependent.
