技巧确定装置和记录介质
摘要：
根据本发明的实施例的一种技巧确定装置设有：输入声采集单元，其采集输入声；音高检测单元，其基于由输入声采集单元采集的输入声而按照时序来检测音高；音量检测单元，其基于由输入声采集单元采集的输入声而按照时序来检测音量；第一起始点检测单元，其针对每个预定时段确定由音量检测单元检测到的音量的变化是否等于或大于规定的阈值，并且检测其中音量的变化等于或大于规定的阈值的时段的起始点作为第一起始点；以及技巧确定单元，其基于由第一起始点检测单元检测到的第一起始点之后的音量的改变和第一起始点之后的音高的变化，来确定输入声的技巧。
摘要（英）：

A technique determining device according to an embodiment of the present invention is provided with: an input sound acquiring unit which acquires an input sound; a pitch detecting unit which detects a pitch in time series on the basis of the input sound acquired by the input sound acquiring unit; a sound volume detecting unit which detects a sound volume in time series on the basis of the input sound acquired by the input sound acquiring unit; a first start point detecting unit which determines, for each predetermined period, whether a variation in the sound volume detected by the sound volume detecting unit is equal to or greater than a prescribed threshold value, and detects, as a first start point, a start point of a period in which the variation in the sound volume is equal to or greater than the prescribed threshold value; and a technique determining unit which determines a technique of the input sound on the basis of a sound volume change after the first start point detected by the first start point detecting unit and a pitch variation after the first start point.
