In general living environments, in order to separate children's voices from backgrounds noise, we developed a sound separation system by a microphone array. We created a game by use of this developed system, and conducted evaluation experiment intended for elementary school children. As a result, we confirmed this system could separate 3 voices, and the(More)
This paper presents a spherical microphone array design which can be used for capturing a sound selectivity and locally. Capturing a sound by microphone array is achieved by method of Delay and Sum Beam Forming (DSBF). In this method, microphone arrangement has a large effect on the directivity. Using beam forming simulation, the authors investigated on the(More)
Mixed sounds can be separated from multiple sound sources by utilizing a microphone array and signal processing. We believe that promotion of interest in this technique can lead to significant developments in future science and technology. Consequently, in order to experience this technique, we designed a language game for children called “KIKIWAKE 3D” that(More)
Evaluating educational programs using traditional methods such as questionnaires and interviews require several trained workers. Therefore, we developed a voice separation system using the Microsoft Kinect sensor for support education research. This system records the voice of the learner in the evaluator’s absence and identifies the learner’s reaction by(More)
This study proposes a system for supporting the Shotoku Taishi game, which is a language play game that uses the voice of children. The Shotoku Taishi game is a group game in which multiple people presenting a problem vocalize different words at the same time and the respondents are required to guess what the combination of the words is. The authors(More)

We developed a sound separation system that uses a microphone array to separate children's voices from background noise in general living environments. Our focus in the development of this system is on “a clear separation of the human voice” so that it will be easy for children to use. Evaluations conducted of sound separation performance in(More)
