To contribute to safe marine navigation by solving the conventional problem that a communication partner cannot know where a present ship is being navigated by recognizing in voice a ship name included in the communication partner when performing international VHF communications between ships and notifying a user of a partner ship displayed on a display device such as ECDIS or displaying an alarm in a case where the communication partner is not the ship being displayed on the display device.SOLUTION: A device for implementing safe navigation utilizing inter-ship communications based on international VHF communications comprises: an electronic marine chart information display unit which displays ship position information included in a communication with an AIS mounted ship; a learning type voice recognition unit which recognizes a voice sequence of voice data when performing voice communications with the AIS mounted ship; a ship name extraction unit which extracts a partner ship name and a partner identification number from the voice sequence recognized by the learning type voice recognition unit; and a positional information superposing unit which superposes an extraction result of the ship name extraction unit on the electronic marine chart information display unit.SELECTED DRAWING: Figure 2

    【課題】船舶間で国際VHF通信を行う場合に、通信相手に含まれる船名を音声認識し、ECDISなどの表示装置に表示されている相手船を利用者に知らせたり、通信相手が当該表示装置に表示されていない船舶だった場合に警告を表示したりすることが可能になり、従来は通信相手が自船に対してどこを航行しているかが判らなかった事を改善し、安全航行に寄与することが出来るようにする。【解決手段】国際VHF通信による船舶間通信を利用した安全航行を実現する装置において、AIS搭載船との通信に含まれる船舶位置情報を表示する電子海図情報表示部と、当該AIS搭載船と音声通信する際に当該音声データの音声列を認識する学習型音声認識部と、前記学習型音声認識部が前記音声列から相手船名及び相手識別番号を抽出する船名抽出部と、前記船名抽出部の抽出結果を前記電子海図情報表示部に重畳する位置情報重畳部と、からなることを特徴とする。【選択図】図2
