PROBLEM TO BE SOLVED: To provide a voice assisting device which can reduce a burden on a user and enables the user to pronounce clearer words.SOLUTION: A voice assisting device 1 includes: an air compressing part 2； an inflation and deflation member 3； a first tube 5； an artificial vocal cord 4； a second tube 6； an opening and closing valve 7 which can switch the second tube 6 between an open state and a closed state； a switch part 8 which keeps the opening and closing valve 7 in the open state to supply air placed in the inflation and deflation member 3 to the artificial vocal cord 4 when being operated by a user to open and keeps the opening and closing valve in the closed state to prevent the air placed in the inflation and deflation member 3 from being supplied to the artificial vocal cord 4 when being operated by the user to close； and air supply control parts 9, 23 which are configured to supply the air from the air compressing part 2 to the inflation and deflation member 3 when the amount of the air in the inflation and deflation member 3 is less than a preset amount of air and to prevent the air from being supplied from the air compressing part 2 to the inflation and deflation member 3 when the amount of the air in the inflation and deflation member 3 is equal to or more than the preset amount of air.【課題】使用者の負担を軽減すると共に、より明瞭な言葉を発声させることのできる音声補助装置を提供する。【解決手段】音声補助装置１は、空気圧縮部２と、膨張収縮部材３と、第１チューブ５と、人工声帯４と、第２チューブ６と、第２チューブ６を開状態又は閉状態に切り替え可能な開閉弁７と、使用者により開操作されたときに膨張収縮部材３に充填された空気が人工声帯４へ供給されるように開閉弁７を開状態とし、使用者により閉操作されたときには、膨張収縮部材３に充填された空気が人工声帯４へ供給されないように前記開閉弁を閉状態とするスイッチ部８と、膨張収縮部材３の空気量が予め設定された空気量未満となった場合には、空気圧縮部２から膨張収縮部材３へ空気を供給させ、膨張収縮部材３の空気量が予め設定された空気量以上となった場合には、空気圧縮部２から膨張収縮部材３へ空気が供給されないようにする空気供給制御部９、２３と、を備える。【選択図】図１
