Abstract (in Japanese) (See Japanese page) 
(in English) This paper describes improvement of sound analysis system for handy-terminal. This system acquires picking time independent of WMS. Firstly, process of dividing frequency spectrum and process of reducing false positive are introduced to the conventional method. The former process divides frequency spectrum and calculates correlation coefficients. The latter process reduces false positive by using the maximum value. Secondly, performance of the improved system is evaluated. Results show that its accuracy increased by approximately 30%. Thirdly, there is no big difference in a result, whether a subject uses handy-terminal with the hand wearing a smart watch or not. Fourthly, performance comparison between subjects shows that the accuracy is wider than the sensitivity. Therefore, it is possible that these processes can improve sound analysis system for handy-terminal.
