Speech Recognition under Stress Condition

Abstract—The objective of this work is to conduct a speech recognition study and evaluate the performance of the same under stressed condition. The speech recognition study is conducted both in isolated word recognition and keyword spotting approaches. The word models are built during training using speech collected from neutral condition. During testing these models are tested with speech signals collected under different stressed conditions to quantify the amount of degradation in each stress condition. It is observed that the performance of the speech recognition system decreases significantly under stressed condition. I
