Abstract

The speech deficits associated with lingual dystonia were analyzed using acoustic analyses. Acoustic analysis focusing on lingual-fractive spectra was conducted using spectrographic displays by the time frequency response (TFR) software program to investigate the hypothesis of abnormal lingual fronting and elevation. A prominent phonetic error was the misperception of the palatial fricative for the alveolar fricative. It was found that a common feature of lingual dystonic contractions involve lingual fronting and lingual elevation during speech production.
