YouTube’s auto-generated closed captions (CC) feature has become a cornerstone of accessibility, allowing users to follow along with videos even in noisy environments or when sound isn’t an option. But when it comes to technical and life-critical content—such as medical videos—how reliable is this tool?
Real-World Test: Analyzing a Medical Clip
We recently tested YouTube auto CC on a video discussing several complex medical topics, including:
Abdominal Aortic Aneurysm
Pyloric Surgery
Anticoagulation in Venous Thromboembolism
Here are some examples of the auto-generated captions:
“An abdominal aotic aneurysm is a surgical emergency…”
“…the riskation an incision is made in the smooth muscle…”
“…allow food to pass from the stomach to the geodum…”
“…options for longerterm anticoagulation in venus thrombolism are a doac warin…”
The Problems We Found
| Issue Type | Caption Error | Medical Accuracy Impact |
|---|---|---|
| Misspelled Terms | “aotic” instead of “aortic” | Can mislead diagnosis |
| Invented Words | “riskation” (not a real word) | Confuses learners |
| Drug Name Confusion | “doac warin” instead of “DOAC or warfarin” | Dangerous miscommunication |
| Anatomical Inaccuracy | “geodum” instead of “duodenum” | Misunderstanding procedures |
Why This Matters
Medical terminology is precise by necessity. Inaccurate transcriptions can:
Lead to misunderstandings
Harm student learning
Undermine credibility
Create potential risks if misapplied
When Can You Trust YouTube CC?
| Use Case | Trust Level |
| Casual or entertainment videos | ✅ Good |
| Conversational content | ✅ Okay |
| Educational or medical content | ❌ Not reliable without review |
What Should You Do Instead?
If you’re creating or consuming medical content:
Use manually uploaded captions
Employ AI tools like Whisper trained with medical vocabularies
Always review or cross-verify subtitles

Conclusion
While YouTube’s auto CC feature is a valuable accessibility tool, it falls short when applied to medical content. The risk of misinterpreting critical terms, medications, or procedures makes it unsuitable for educational or professional healthcare use without thorough review.
For students, educators, and healthcare professionals, accuracy is non-negotiable. Always choose videos from credible medical sources and verify whether captions are manually curated or auto-generated. When in doubt, don’t rely on them for essential learning.
