Research and development of a methodology for on-demand broadcast of local FM radio and a retrieval technology for spoken broadcast data sets

我们研究和开发了一种本地调频广播的点播方法和语音广播数据集的检索技术。假设语音无线电数据，我们进行了一项技术的研究和开发，以检索数据中感兴趣的部分。由于这种地方调频广播包含方言，我们通过引入一个比音节短的新单元来开发检索词汇外词语的方法，并成功地实现了开放式词汇检索和检索的改进。此外，我们还建立了日本信息处理学会工作组下许多研究机构最近提出的用于评估检索方法的标准测试集，并认识到了一项学术社团活动的研究基础和贡献。

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.
