This paper describes system for query-by-example spoken term detection built for QUESST 2015 evaluation. The system uses dynamic time warping to detect spoken term utilizing bottle-neck features.
All our systems are based on Dynamic Time Warping (DTW). These systems use bottle-neck features (BN) as input. The bottle-neck feature extractors were trained on GlobalPhone Czech, Portuguese, Russian and Spanish languages, so our approach is in low-resource category. We also aimed on T1/T2/T3 types of query search for late submission systems. System calibration and fusion were based on binary logistic regression.
