Abstract

The paper presents a study of usability of x-vectors for adaptationof automatic speech recognition (ASR) systems. Xvectorsare Neural Network (NN)-based speaker embeddingsrecently proposed in speaker recognition (SR). They quicklyreplaced common i-vectors and became new state-of-the-arttechnique. Here, the same approach is adopted for ASR withthe hope of similar outcome. All experiments were done onASR for the latest IARPA MATERIAL evaluation running onPashto language. Over 1% absolute improvement was observedwith x-vectors over traditional i-vectors, even whenthe x-vector extractor was not trained on target Pashto data.
