Abstract (in Japanese) (See Japanese page) 
(in English) This paper proposes a novel language modeling approach called latent word recurrent neural network language model, which solves the problems present in both recurrent neural network language models (RNNLMs) and latent word language models (LWLMs). The proposed model has a soft class structure based on a latent variable space as well as LWLM, where the latent variable space is modeled using RNNLM. This paper also details the parameter inference method and two kinds of usages for natural language processing tasks. Our experiments show effectiveness of the proposed model on a perplexity evaluation for the Penn Treebank corpus and an automatic speech recognition evaluation for Japanese spontaneous speech tasks.
