PROBLEM TO BE SOLVED: To construct an optimal system to prevent aspiration pneumonia by analyzing frequency of vocal sound when an examinee sings in accordance with accompaniment sound and by quantifying proficiency level of abdominal breathing for determination.SOLUTION: The system extracts frequency component information on an attention section of a specific frequency band signal for capturing a difference in the abdominal breathing from a vocal sound of the examinee, where sound pressure is to be heightened. Then, tendency of one measurement result is indicated in a single value by calculating the information, and by analyzing the temporal transit, the proficiency level of the abdominal breathing can be determined.COPYRIGHT: (C)2012,JPO&INPIT【課題】 伴奏音に合せて被験者が歌うときの発声音を周波数解析し腹式呼吸の習熟度を数量化して判定することにより、誤嚥性肺炎を予防するために最適なシステムを構築する【解決手段】 被験者の発声音から腹式呼吸の差異を捉える特定周波数帯の信号でかつ音圧が高まるべき注目区間の周波数成分情報を抽出し、それを演算することによって一回の測定結果の傾向を単一の数値で提示し、時間経過を分析して腹式呼吸の習熟度を判定可能とした。【選択図】図1
