Abstract
The OpenKWS14 keyword search evaluation is one of the most challenging and influential evaluations in the field of speech recognition. Its goal is to build a high-performance keyword search system for a minority language with limited training data in a short period of time. We present the system of the Department of Electronic Engineering, Tsinghua University (THUEE team) for the OpenKWS14 keyword search evaluation. The highlights of the system include the use of convolutional maxout neural networks for acoustic modeling and the use of neural network language models for one-pass lattice generation. The final system is a fusion of 8 sub-systems. The system has achieved an actual term weighted value (ATWV) of 0.5107 for the full language pack (FullLP) condition in the evaluation, ranking third among the participating teams.
