This comparative multi-case qualitative study used 3 hypothetical vignettes. Ten experienced SLTs (\u226510\u2009years) participated in semi-structured interviews, providing assessment, diagnosis and therapy plans for each vignette. ChatGPT-4o was presented with identical, standardized Turkish prompts over five\u2009consecutive days to evaluate the model\u2019s temporal consistency in clinical reasoning. All outputs were analyzed with content analysis, and day-to-day consistency of ChatGPT themes was examined. ChatGPT-4o and SLTs showed substantial overlap in core practices such as case history, spontaneous speech analysis, key diagnostic labels, and emphasis on generalization and caregiver involvement. However, SLTs utilized broader, locally normed assessment tools and offered more flexible, individualized and context-sensitive therapy approaches. ChatGPT-4o\u2019s responses were more standardized and showed stable thematic patterns across days, yet they did not reflect the clinical nuance or contextual adaptation observed in SLTs\u2019 reasoning. ChatGPT-4o can approximate expert-like reasoning in structured scenarios and may serve as a clinical decision support aid. Nonetheless, it does not replace experienced SLTs, particularly for culturally grounded, person-specific assessment and intervention planning.<\/jats:p>","DOI":"10.1177\/00469580261445316","type":"journal-article","created":{"date-parts":[[2026,4,24]],"date-time":"2026-04-24T13:44:30Z","timestamp":1777038270000},"update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":3,"title":["Artificial Intelligence in Speech and Language Therapy: A Qualitative Comparative Analysis of Clinical Applications and Outcomes"],"prefix":"10.1177","volume":"63","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-7630-1956","authenticated-orcid":false,"given":"\u0130brahim Can","family":"Ya\u015fa","sequence":"first","affiliation":[{"name":"Bah\u00e7e\u015fehir University, Be\u015fikta\u015f, Istanbul, T\u00fcrkiye"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Muhsin","family":"D\u00f6lek","sequence":"additional","affiliation":[{"name":"Bah\u00e7e\u015fehir University, Be\u015fikta\u015f, Istanbul, T\u00fcrkiye"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Seda","family":"Eyilikeder Tekin","sequence":"additional","affiliation":[{"name":"Bah\u00e7e\u015fehir University, Be\u015fikta\u015f, Istanbul, T\u00fcrkiye"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ay\u015fe Serra","family":"Kaya","sequence":"additional","affiliation":[{"name":"Bah\u00e7e\u015fehir University, Be\u015fikta\u015f, Istanbul, T\u00fcrkiye"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"P\u0131nar","family":"Akg\u00fcn","sequence":"additional","affiliation":[{"name":"Bah\u00e7e\u015fehir University, Be\u015fikta\u015f, Istanbul, T\u00fcrkiye"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Sakine Deniz","family":"Y\u0131lmaz","sequence":"additional","affiliation":[{"name":"Bah\u00e7e\u015fehir University, Be\u015fikta\u015f, Istanbul, T\u00fcrkiye"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Selin","family":"Tokalak","sequence":"additional","affiliation":[{"name":"Bah\u00e7e\u015fehir University, Be\u015fikta\u015f, Istanbul, T\u00fcrkiye"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"179","published-online":{"date-parts":[[2026,4,24]]},"reference":[{"key":"e_1_3_3_2_2","doi-asserted-by":"publisher","DOI":"10.2196\/48392"},{"key":"e_1_3_3_3_2","doi-asserted-by":"publisher","DOI":"10.1177\/0840470419873123"},{"key":"e_1_3_3_4_2","doi-asserted-by":"publisher","DOI":"10.1080\/02687038.2023.2189513"},{"key":"e_1_3_3_5_2","doi-asserted-by":"publisher","DOI":"10.1136\/svn-2017-000101"},{"key":"e_1_3_3_6_2","article-title":"A comparison of deep learning performance against healthcare professionals in detecting diseases from medical imaging: a systematic review and meta-analysis","volume":"1","author":"Liu X","year":"2019","unstructured":"Liu X, Faes L, Kale AU, et al.
