| Abstract: | To improve in-vocabulary performance in Mongolian speech keyword spotting task, we propose a Mongolian speech keyword spotting method by searching the stem according to the characteristic of Mongolian word-formation rule. First, Mongolian speech is decoded to lattice file by Segmentation-based LVCSR system, and this lattice file is converted to a confusion network. Then, we detect the keywords according to their stems among the confusion network. Experimental results show that the proposed method outperforms baselines based on word confusion network. |
