A comprehensive benchmarking of 26 speech-to-text (STT) models was conducted on long-form medical dialogue using the PriMock57 dataset, consisting of 55 files and over 81,000 words. The models were ranked based on their average Word Error Rate (WER), with Google Gemini 2.5 Pro leading at 10.79% and Parakeet TDT 0.6B v3 emerging as the top local model at 11.9% WER. The evaluation also considered processing time per file and noted issues such as repetition-loop failures in some models, which required chunking to mitigate. The full evaluation, including code and a complete leaderboard, is available on GitHub, providing valuable insights for developers working on medical transcription technology. This matters because accurate and efficient STT models are crucial for improving clinical documentation and reducing the administrative burden on healthcare professionals.
The evaluation of 26 speech-to-text (STT) models on long-form medical dialogue highlights the importance of accurate transcription in healthcare settings. Medical professionals rely on precise documentation to ensure patient safety and effective communication. The benchmark study provides a comprehensive comparison of both local and cloud-based STT models, offering insights into their performance, speed, and suitability for medical dialogues. The analysis reveals that while Google’s Gemini 2.5 Pro leads with the lowest word error rate (WER), local models like Parakeet TDT are also competitive, offering fast processing times.
Understanding the performance of these models is crucial for developers and healthcare providers aiming to integrate STT solutions into clinical workflows. The findings show that some models, such as Google MedASR, may not be well-suited for dialogue-heavy tasks, indicating the need for specialized tuning. The presence of repetition-loop failure modes in certain models underscores the challenges in processing complex medical dialogues, where chunking with overlap might be necessary to maintain accuracy. Such insights are valuable for enhancing the reliability of STT systems in medical environments.
The improvements observed in models like OpenAI’s GPT-4o Mini, which saw a significant reduction in WER after a recent update, demonstrate the rapid advancements in STT technology. These developments are crucial as they directly impact the efficiency and accuracy of medical transcription services. By providing a detailed leaderboard and open-sourcing the evaluation code, the study encourages further research and development in this field, fostering innovation and collaboration among developers and researchers.
Ultimately, the benchmark study serves as a vital resource for those involved in the deployment of STT systems in healthcare. It highlights the need for continuous evaluation and optimization of these models to meet the specific demands of medical dialogue transcription. As the healthcare industry increasingly adopts digital solutions, ensuring the accuracy and efficiency of STT models will be essential in supporting clinicians and enhancing patient care. The open-source nature of the evaluation also promotes transparency and allows for ongoing improvements in STT technology.

The benchmarking study presents a clear picture of current STT models’ performance in medical dialogues, but I’m curious about the practical implications of these findings. How do you see the top models addressing the unique challenges of medical terminology and dialect variation in real-world applications?
The findings suggest that the top models, like Google Gemini 2.5 Pro, are better equipped to handle medical terminology due to their lower Word Error Rates. However, dialect variation remains a challenge, and ongoing training with diverse datasets could improve performance. For more detailed insights, please refer to the full article linked in the post.
