Case studies

A 67-year-old right-handed male presents after a left MCA. Speech is effortful, but not always clearly segmented. The patient attempts self-corrections and sometimes restarts mid-word. Intonation is mildly monotonous.​

​

Observations:​

Word Syllable Duration (WSD): Avg. 320 ms/syllable ​

Speech Sample: “The bas…buh…baseball fell” (multiple restarts)​

SMRs: Irregular timing (“pa-ta-ka” → “pa…ka…ta”), variable errors​

AMRs: Slower but rhythmic (“pa-pa-pa” consistently accurate)

A 60-year-old female post left hemisphere stroke exhibits fluent yet error-prone speech. She produces substitutions and occasional neologisms. ​

​

Observations:​

Word Syllable Duration (WSD): Avg. 250 ms/syllable (within normal range)​

Speech Sample: “The bapple fell off the cain” (target: “The apple fell off the chain”)​

SMRs: Sequentially accurate, normal rate​

AMRs: Consistent, no distortions
