    • Sound data acquisition means acquires, from a sound input device, sound data representing a sound signal. First evaluation means evaluates the sound signal represented by the sound data, by using a first criterion for detecting whether or not the sound inputted into the sound input device is a breath. Second evaluation means evaluates the sound signal represented by the sound data, by using a second criterion which is different from the first criterion. Breath detection means detects that a breath is inputted into the sound input device at least when the first evaluation means makes an affirmative evaluation, in a first period in which whether or not a breath is started to be blown into the sound input device is determined, and detects that a breath is inputted into the sound input device when at least one of the first evaluation means and the second evaluation means make an affirmative evaluation, in a second period in which whether or not a breath continues to be blown into the sound input device is determined.
    • 声音数据获取装置从声音输入装置获取表示声音信号的声音数据。 第一评估装置通过使用用于检测输入到声音输入装置中的声音是否是呼吸的第一标准来评估由声音数据表示的声音信号。 第二评估装置通过使用不同于第一标准的第二标准来评估由声音数据表示的声音信号。 呼吸检测装置至少在第一评估装置进行肯定评估时检测到呼吸被输入到声音输入装置中,在确定是否开始吹入声音输入装置的呼吸的第一时段中, 并且当在呼吸继续吹入声音输入的第二时段中,当第一评估装置和第二评估装置中的至少一个进行肯定评估时,检测到呼入输入到声音输入装置中 设备确定。
