摘要翻译:
未来上下文信息的使用通常被证明对声学建模是有帮助的。然而,对于递归神经网络(RNN)来说,在保持较低的模型时延的同时,如何有效地对未来时态环境进行建模并不是一件容易的事情。在本文中,我们试图设计一个能够有效而直接地利用未来背景的RNN声学模型,并且模型的时延和计算量都尽可能低。该模型基于最小门控递归单元(mGRU),并插入一个输入投影层。为该体系结构专门设计了两个上下文模块,即时态编码和时态卷积,以对未来上下文进行建模。在Switchboard任务和一个内部汉语ASR任务上的实验结果表明,该模型比LSTM和mGRU模型有更好的性能,而在线解码的最大时延为170 ms。该模型的性能甚至超过了非常强的基线TDNN-LSTM,具有更小的模型延迟和几乎少一半的参数。

二级分类:Computation and Language 计算与语言
分类描述:Covers natural language processing. Roughly includes material in ACM Subject Class I.2.7. Note that work on artificial languages (programming languages, logics, formal systems) that does not explicitly address natural-language issues broadly construed (natural-language processing, computational linguistics, speech, text retrieval, etc.) is not appropriate for this area.

英文摘要:
The use of future contextual information is typically shown to be helpful for acoustic modeling. However, for the recurrent neural network (RNN), it's not so easy to model the future temporal context effectively, meanwhile keep lower model latency. In this paper, we attempt to design a RNN acoustic model that being capable of utilizing the future context effectively and directly, with the model latency and computation cost as low as possible. The proposed model is based on the minimal gated recurrent unit (mGRU) with an input projection layer inserted in it. Two context modules, temporal encoding and temporal convolution, are specifically designed for this architecture to model the future context. Experimental results on the Switchboard task and an internal Mandarin ASR task show that, the proposed model performs much better than long short-term memory (LSTM) and mGRU models, whereas enables online decoding with a maximum latency of 170 ms. This model even outperforms a very strong baseline, TDNN-LSTM, with smaller model latency and almost half less parameters.
