In recent years, processing sound signal in a real acoustic environment has become a subject of research. The importance of such research is increasing in varied fields of application such as man-machine interface, speech recognition, environmental sound recognition, echo canceller, active noise control and the like. However, no standard database is presently available.
A sound scene database in real acoustic environment will contribute to core research as a standard for objective comparison and evaluation of research results. Though a microphone array can measure factors in a three-dimensional acoustic environment, using equipment with multiple signal channels is costly and difficult. For that reason a common database is valuable in that it would allow research to be conducted even without the suitable facilities.
The RWCP Sound Scene Database in Real Acoustic Environment is a common database for research use that has been developed by the Real Acoustic Environment Subgroup of RWCP Intellectual Resource for Research and Development Working Group in Real World Computing Partnership, as a work of Real World Computing Program. The data were recorded from 1998 to 2000.
The content includes speech measurement data collected by microphone array and dry source of non-speech sound. These data are essential for sound scene research using a microphone array in a real acoustic environment. The content also includes explanation of algorithms related to measurements, software using the algorithms and a study case using these measurement data.
|3. Distribution and How to get|
The database may be put to unlimited use in research work and other applications such as product development. It is primarily intended for research and technological development of non-speech sound and microphone array.
Usage is subject to the following conditions.
The database is contained in three DVD-ROMs. To obtain a copy, please refer to the section entitled "How to obtain DVD-ROM" in this guide. Distribution is limited in number.
