“…Given the limited stimuli and scope of this study, the changes in spectral qualities of vowels and speech rate were examined, as these were the speech characteristics the authors perceived as most salient. In addition, vowel quality changes are described as major contributors to perceived foreign accents in FAS (Dankovičová et al, 2001;Blumstein and Kurowski, 2006;Perkins et al, 2010). Furthermore, as AE has a larger vowel inventory than Hebrew, accentedness would be expected to reveal itself in vowel production.…”

“…In rare cases, atypical speech produced by monolinguals who did not speak another language before their stroke is perceived as spoken with a foreign accent and is termed 'Foreign Accent Syndrome' (FAS) (Whitaker, 1982;Perkins, Ryalls, Carson and Whiteside, 2010). Bilingual and multilingual speakers with aphasia have been reported to exhibit the same types of language and speech deficits reported for monolinguals (Paradis, 2004).…”

“…A handful of studies have examined the acoustics of pre-versus post-CVA utterances of speakers with FAS (Ingram, 1992;Kurowski et al, 1996;Dankovičová, Gurd, Marshall, MacMahon, Stuart-Smith, Coleman and Slater, 2001). One study (Perkins et al, 2010) analysed the pre-and post-recovery speech of two individuals whose normal speech patterns returned following FAS. Unlike for many FAS cases, EC's speech, examined seven years after the stroke, retained the post-CVA accent.…”

This study documents patterns of change in speech production in a multilingual with aphasia following a cerebrovascular accident (CVA). EC, a right-handed Hebrew-English-French trilingual man, had a left fronto-temporo-parietal CVA, after which he reported that his (native) Hebrew accent became stronger in his (second language) English. Recordings of his pre- and post-CVA speech permitted an investigation of changes in his accent. In sentence- and segment-listening tasks, native American English listeners (n = 13 and 15, respectively) judged EC's pre- and post-CVA speech. EC's speech was perceived as more foreign-accented, slow, strained and hesitant, but not less intelligible, post-CVA. Acoustic analysis revealed less coarticulation and longer vowel- and word-durations post-CVA. This case extends knowledge about perceptual and acoustic changes in speech production in multilinguals following CVAs. It is suggested that EC's stronger accent post-CVA may have resulted from damage to the neuronal networks that led to impairment in his other language domains.

“…Frequently reported vocalic errors include alterations in vowel length, i.e. lengthening (Blumstein, Alexander, Ryalls, Katz & Dworetzky, 1987;Graff-Radford, Cooper, Colsher & Damasio, 1986) as well as shortening (Ingram, McCormack & Kennedy, 1992;Perkins, Ryalls, Carson & Whiteside, 2010) and tenseness (e.g. Katz, Garst & Levitt, 2008;Whitaker, 1982).…”

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.
