Abstract
BACKGROUND: Clinical documentation is vital for effective communication, legal accountability and the continuity of care in healthcare. Traditional documentation methods, such as manual transcription, are time-consuming, prone to errors and contribute to clinician burnout. AI-driven transcription systems utilizing automatic speech recognition (ASR) and natural language processing (NLP) aim to automate and enhance the accuracy and efficiency of clinical documentation. However, the performance of these systems varies significantly across clinical settings, necessitating a systematic review of the published studies. METHODS: A comprehensive search of MEDLINE, Embase, and the Cochrane Library identified studies evaluating AI transcription tools in clinical settings, covering all records up to February 16, 2025. Inclusion criteria encompassed studies involving clinicians using AI-based transcription software, reporting outcomes such as accuracy (e.g., Word Error Rate), time efficiency and user satisfaction. Data were extracted systematically, and study quality was assessed using the QUADAS-2 tool. Due to heterogeneity in study designs and outcomes, a narrative synthesis was performed, with key findings and commonalities reported. RESULTS: Twenty-nine studies met the inclusion criteria. Reported word error rates ranged widely, from 0.087 in controlled dictation settings to over 50% in conversational or multi-speaker scenarios. F1 scores spanned 0.416 to 0.856, reflecting variability in accuracy. Although some studies highlighted reductions in documentation time and improvements in note completeness, others noted increased editing burdens, inconsistent cost-effectiveness and persistent errors with specialized terminology or accented speech. Recent LLM-based approaches offered automated summarization features, yet often required human review to ensure clinical safety. CONCLUSIONS: AI-based transcription systems show potential to improve clinical documentation but face challenges in accuracy, adaptability and workflow integration. Refinements in domain-specific training, real-time error correction and interoperability with electronic health records are critical for their effective adoption in clinical practice. Future research should also focus on next-generation "digital scribes" incorporating LLM-driven summarization and repurposing of text. CLINICAL TRIAL NUMBER: Not applicable.

Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from it
