PROBLEM TO BE SOLVED: To enable all information to be surely processed without failing to hear any in achieving a function to convert a voice call into characters and record them in a train radio system without requiring a large scale system update.SOLUTION: A train and a direction center have an addition device and a character display device respectively. The addition device is interconnected with a radio device and a voice input/output part connected to the radio device respectively. The addition device includes a voice recognition device for converting a voice signal at the voice input/output part into characters, and a recording part for recording the characters obtained by converting the voice signal into characters by the voice recognition device. The character display device displays the characters obtained by converting the voice signal into characters by the voice recognition device, and includes a button for giving an instruction to display the past history retroactively, and the recording part reads out the information on the past history on which the instruction is given by the button in the character display device.SELECTED DRAWING: Figure 1

    【課題】列車無線システムに音声通話を文字化・記録するような機能を実現する場合において、大規模なシステム更新を必要とせずに、全ての情報を聞き逃さず確実に処理できるようにする。【解決手段】列車及び指令所が、それぞれ、付加装置と文字表示装置とを有する。付加装置は、無線装置及び前記無線装置に接続された音声入出力部に対してそれぞれ相互接続されている。この付加装置は、音声入出力部での音声信号を文字化する音声認識装置と、この音声認識装置で文字化した文字を記録する記録部とを有する。文字表示装置は、音声認識装置で文字化した文字を表示するもので、過去の履歴を遡って表示することを指示するボタンを有し、記録部は、前記ボタンによって指示された過去の履歴の情報を前記文字表示装置に読み出す。【選択図】図1
