Abstract (in Japanese) (See Japanese page) 
(in English) NHK is pursuing the development of a system using speech recognition for the closed caption production of live broadcasting and transcription of interview video footage. In many cases, it is possible to acquire images as well as audio from video footage. From the images, it is expected to obtain information that leads to improvement of language model accuracy such as domain identification. Therefore, we proposed two methods to adopt image features to language models. The first method is to extract the hidden layer of the image recognition model, and the second is to incorporate the image description captions which automatically generated. Compared to the baseline recurrent neural network language model, perplexity decreased in the first method.
