Foreign accent syndrome (FAS) is a rare motor speech language disorder that causes a change in patient’s accent making it sound foreign or, in rare cases, altered. In the present paper the language disorder of a rare case of regionally like altered accent has been studied and a neurolinguistic description has been presented. To reach this purpose the lesion region of the patient’s brain is analyzed, and then a pre-stroke and post- stroke speech sample is compared phonetically and prosodically. Finally based on the neurolinguistic findings and a judging panel the nature of the post-stroke accent is analyzed. The patient is a native Farsi speaker and after the stroke it was noticed the appearance of a Yazdi accent in his speech following a right temporo-occipital ischemic lesion. Worthy of mention this case study presents the first reported case of a Middle East FAS patient. Both phonetic-prosodic and perceptive analysis of the patient’s speech samples exhibited that the new accent is not a complete Yazdi accent but a combination of both his native accent and Yazdi. The patient used the Yazdi-like accent as a compensatory strategy to obviate his limit access to the knowledge of his native accent after the stroke.
