Question 1

What WER should I expect?

Accepted Answer

Top models achieve 3-5% WER on clean audio (95-97% accuracy). With background noise, expect 8-15% WER. Heavy accents or poor audio may reach 20%+ WER.

Question 2

Is lower WER always better?

Accepted Answer

Usually, but context matters. Some models trade accuracy for speed. For real-time applications, slightly higher WER may be acceptable for lower latency.
