5th International Conference on Spoken Language Processing
We argue that phonetically invariant realizations of phonological categories imply the synchronic and diachronic imperviousness of such categories to phonological rules and sound laws. We claim that phonetic invariance is the foundation of phonological stability. The category we discuss in this contribution is the pitch-accent. We provide a parametric phonetic description of this phonological category. By means of a parametrization technique we apply this description to the contrastive pitch-accents of Lithuanian. The statistic differences between acute and circumflex pitch-accents derived by the parametrization provide a basis for the discussion of synchronic and diachronic behavior of the phonetically nonbalanced phonological contrasts.
