Sensors, Vol. 23, Pages 857: A Comparative Investigation of Automatic Speech Recognition Platforms for Aphasia Assessment Batteries
Qiang Fang The rehabilitation of aphasics is fundamentally based on the assessment of speech impairment. Developing methods for assessing speech impairment automatically is important due to the growing number of stroke cases each year. Traditionally, aphasia is assessed manually using one of the well-known assessment batteries, such as the Western Aphasia Battery (WAB), the Chinese Rehabilitation Research Center Aphasia Examination (CRRCAE), and the Boston Diagnostic Aphasia Examination (BDAE). In aphasia testing, a speech-language pathologist (SLP) administers multiple subtests to assess people with aphasia (PWA). Th...

Categorical perception of lexical tones in Chinese people with post-stroke aphasia
This study used the categorical perception (CP) paradigm, a fine-grained perceptual method, to investigate the perceptual performance of lexical tones in Chinese people with post-stroke aphasia (PWA). Twenty patients with post-stroke aphasia (10 Broca's and 10 Wernicke's) and ten neurologically intact age-matched control participants were recruited to complete both identification and discrimination tasks of the Mandarin Tone 1-2 continuum. In addition, all participants completed tests on their auditory comprehension ability and working memory. The results showed that both Broca's and Wernicke's patients exhibited reduced s...

Changes in the corpus callosum during the recovery of aphasia: A case report
Rationale: The corpus callosum, which is the most important fiber pathway linking the bilateral hemispheres, plays a key role in information access, as well as the functional coordination and reorganization between the bilateral hemispheres. However, whether the corpus callosum will undergo structural changes during the recovery of aphasia is still unclear. In the current study, a Chinese aphasic patient with stroke was reported to develop changes in the corpus callosum after speech therapy. Patient concerns: A 33-year-old right-handed male patient had aphasia only without limb paralysis at 14 months after stroke. Di...
