#1 Two-stage system for robust neutral/lombard speech recognition [PDF] [Copy] [Kimi1]

Authors: Hynek Bořil ; Petr Fousek ; Harald Höge

Performance of current speech recognition systems is significantly deteriorated when exposed to strongly noisy environment. It can be attributed to background noise and Lombard effect (LE). Attempts for LE-robust systems often display a tradeoff between LE-specific improvements and the portability to neutral speech. Therefore, towards LE-robust recognition, it seems effective to use a set of conditions-dedicated subsystems driven by a condition classifier, rather than attempting for one universal recognizer.
