| Research Abstract |
We conducted the research and development of a methodology for on-demand broadcast of local FM radio and a retrieval technology for spoken broadcast data sets. Assuming spoken radio data, we conducted the research and development of a technology for retrieving a section of interest in the data. Because such local FM broadcast includes dialects, we developed the method for retrieving out-of-vocabulary terms by introducing a new unit that is shorter than a phone, and succeeded in open vocabulary retrieval and the improvement of retrieval. Furthermore, we established standard test collections for evaluating retrieval methods that have been recently proposed from many research institutes under the working group in Information Processing Society of Japan, and realized the research basis and the contribution of an academic society activity.
