In the paper, we describe our Chinese-English Speech-to-Text (STT) systems for OC16 Chinese-English Mix-ASR Challenge. This challenge focuses on the transcription of Chinese-English code-mixing speech. Code-mixing speech which refers to the intra-sentential switching of two different languages in a spoken utterance proposes a very challenging task for the ASR research community. In this challenge,...
Recently, deep neural networks(DNNs) have achieved excellent results on benchmarks for acoustic modeling of speech recognition. By randomly discarding network units, a strategy which is called as dropout can improve the performance of DNNs by reducing the influence of over-fitting. However, the random dropout strategy treats units indiscriminately, which may lose information on distributions of units...
