Laboratory

Natural language as a tool in real world is a target of my work, and it covers the areas such as speech recognition, multi-modal dialog system, speech interface, and information retrieval.
Natural language has two major functions; interactional function and transactional function. The former have been assumed to be covered by spoken langauge and the other have been assumed to be covered by written language.
One of my major research topics is to utilize spoken language as transactional using speech technologies. For interactional aspects, I am exploring the possibilities of a prosodic aspects in spoken language interface.
I will address to clarify the ability of natural language in real world applications.
