Error Rate is Not Enough: Costs of Augmentation in Low-Resource ASR

- What happened
- Research shows data augmentation methods for low-resource speech recognition help in complementary ways, with different error patterns that combine better than individually.
- Why it matters
- Engineers building ASR systems for languages with limited training data should consider which augmentation methods address their specific error types rather than only comparing aggregate error rates.
- Watch out
- Benefits from combining augmentation methods diminish significantly once training data exceeds 100 hours, so this approach matters most in genuinely low-resource scenarios.
