On the force of articulation in foreign accent syndrome Dicky Gilbers, Roel Jonkers, Fennetta van der Scheer & Judith Feiken Abstract The Foreign Accent Syndrome (FAS) is a rare speech disorder leading to a perceived presence of a new accent in the speech of the participant with FAS. The foreign accent in these speakers is assumed on the basis of stereotypical segmental characteristics. In this paper we will present a model that considers these stereotypical characteristics. According to this model, the different aspects of the perception of FAS can be com- bined to one underlying phonological principle, namely the force of articulation: we hypothesize that people perceive a foreign accent in FAS speakers because of a larger amount of fortition (force of articulation) put in the speech of the FAS speaker. In general, we expect that the characteristics of fortis speech show that the direc- tion in perception of an accent of FAS will go from a language with relatively more lenition, such as Dutch, into a language with relatively less lenition, such as German. The model is illustrated with data of two Dutch speakers with a perceived foreign ac- cent. The most important characteristics of fortition in our FAS speakers were the low speech rate and the longer duration of VOT, release burst and occlusion time. Syllable isochrony also happened to be characteristic for FAS speech, which explains the per- ception of stress-timed languages, such as English, as syllable-timed languages, such as French. 1.
