This chapter introduces the idea of user-generated dialogue content and describes our experimental exploration aimed at clarifying the mechanism and conditions that makes it workable in practice. One of the attractive points of a speech interface is to provide a vivid sense of interactivity that cannot be achieved with a text interface alone. This study proposes a framework that spoken dialogue systems are separated into content that can be produced and modified by users, and the systems that drive the content, and seek to clarify (1) the requirements of systems that enable the creation of attractive spoken dialogue, and (2) the conditions for the active generation of attractive dialogue content by users, while attempting to establish a method for realizing them. Experiments for validating user dialogue content generation were performed by installing interactive digital signage with a speech interface in public spaces as a dialogue device, and implementing a content generation environment for users via the Internet. The proposed framework is expected to lead to a breakthrough in the spread of using speech technology.

16TH ANNUAL CONFERENCE OF THE INTERNATIONAL SPEECH COMMUNICATION ASSOCIATION (INTERSPEECH 2015), VOLS 1-5 2390 - 2394 2015

Recurrent neural network language models have been shown to consistently reduce the word error rates (WERs) of large vocabulary speech recognition tasks. In this work we propose to enhance the RNNLMs with prosodic features computed using the context of the current word. Since it is plausible to compute the prosody features at the word and syllable level we have trained the models on prosody features computed at both these levels. To investigate the effectiveness of proposed models we report perplexity and WER for two speech recognition tasks, Switchboard and TED. We observed substantial improvements in perplexity and small improvements in WER.

HAI 2014 - Proceedings of the 2nd International Conference on Human-Agent Interaction 323 - 330 2014.10
Language：English Publishing type：Research paper (international conference proceedings) Publisher：Association for Computing Machinery, Inc
In this paper, we propose a voice interaction system using 3D-CG virtual agents for stand-alone smartphones. Because the proposed system can handle speech recognition and speech synthesis on a stand-alone smartphone differently from the existing mobile voice interaction systems, this system enables us to talk naturally without encountering delays caused by network communications. Moreover, proposed system can be fully customized by dialogue scripts, Java-based plugins, and Android APIs. Therefore, developers can make original voice interaction systems for smartphones easily based on proposed system. We have made a subset of the proposed system available as opensource software. We expect that this system will contribute to studies of human-agent interaction using smartphones.
