An Acoustical Study of the Fricative /s/ in the Speech of Palestinian-speaking Broca's Asphasics – Preliminary Findings

Hisham Adam
This study was conducted with four Palestinian-speaking Broca's aphasics and four normal speakers to examine the production of the fricative /s/ and to analyze the difference in acoustic patterns between the two groups.
