“…Speech characteristics of the two FAS speakers reported in this study are comparable to those of AOS speakers (segment distortion, slow speech rate, simplified rhythm) and are therefore consistent with the results reported by Cohelo and Robb (2001), Moen (2000Moen ( , 2006, Varley et al (2006), Naidoo et al (2008), Verhoeven and Mariën (2010) and Kanjee et al (2010). Unlike AOS speech, however, symptoms are relatively mild and somewhat similar to the speech of foreign speakers.…”

“…Laures-Gore et al (2006) also found a contrast between voiced and voiceless consonants with her FAS participants but VOT values were reversed compared with American English ones (longerlag VOT for voiced stops and shorter-lag VOT for voiceless). Kanjee et al (2010) found overlapping and variable values in a Canadian English FAS speaker using a reading task. A reduction of contrast between voiced and voiceless consonants in a less controlled task was also observed in DF.…”

“…Higher vowel dispersion, i.e. variability in formant values for the same vowel target, has also been observed (Blumstein et al, 1987;Kanjee, Watter, Sévigny, & Humphreys, 2010), as well as diphthongization (Graff-Radford et al, 1986;Lippert-Gruener, Weinert, Greisbach, & Wedekind, 2005;Naidoo, Warriner, Oczkowski, Sévigny, & Humphreys, 2008) or monophthongization (Dankovičová et al, 2001;Kurowski et al, 1996).…”

Foreign accent syndrome (FAS) is an acquired neurologic disorder in which an individual suddenly and unintentionally speaks with an accent which is perceived as being different from his/her usual accent. This study presents an acoustic-phonetic description of two Quebec French-speaking cases. The first speaker presents a perceived accent shift to Acadian French (French spoken in the easternmost provinces of Canada), whereas the second acquired an accent identified as Germanic. Speech seems affected by constraints on the coordination of articulatory gestures, expressed by distortions in the production of segments. These distortions do not necessarily result from changes in suprasegmental settings (slow speech rate and isochronous syllable pattern were observed) but may cause the disappearance of markers used for Quebec French accent recognition. Reported speech characteristics are comparable to those of speakers with apraxia of speech (AOS) but symptoms are relatively mild and somewhat similar to the speech of foreign speakers. For this reason, the position that FAS may be a mild form or subtype of AOS, as maintained by other authors, should be seriously considered.

Foreign accent syndrome (FAS) is a motor speech disorder in which changes to segmental as well as suprasegmental aspects lead to the perception of a foreign accent in speech. This paper focuses on one suprasegmental aspect, namely that of intonation. It provides an in-depth analysis of the intonation system of four speakers with FAS with the aim of establishing the intonational changes that have taken place as well as their underlying origin. Using the autosegmental-metrical framework of intonational analysis, four different levels of intonation, i.e. inventory, distribution, realisation and function, were examined in short sentences. Results revealed that the speakers with FAS had the same structural inventory at their disposal as the control speakers, but that they differed from the latter in relation to the distribution, implementation and functional use of their inventory. The current results suggest that these intonational changes cannot be entirely attributed to an underlying intonation deficit but reflect secondary manifestations of physiological constraints affecting speech support systems and compensatory strategies. These findings have implications for the debate surrounding intonational deficits in FAS, advocating a reconsideration of current assumptions regarding the underlying nature of intonation impairment in FAS.
