PROBLEM TO BE SOLVED: To enable voice information to be switched properly by a simple operation without damaging tone quality of the voice information from a tablet or the like, and without obstructing emergency broadcast or the like.SOLUTION: A voice information switching device for a railway vehicle includes voice output means 70 for outputting voice information, sound collection means 10 for collecting voice information so as to output voice from the voice output means 70, and voice information storage means 20 that can output voice from the voice output means 70, and stores desired voice information beforehand so as to selectively reproduce it. It has a sound collection broadcast mode for voice-outputting voice information input from the sound collection means 10 through the voice output means 70, and a reproduction broadcast mode for reproduction-outputting the stored voice information through the voice output means 70 when a predetermined voice level of the voice information storage means 20 is detected. When the sound collection means 10 is selected in the reproduction broadcast mode, the mode is switched to the sound collection broadcast mode.SELECTED DRAWING: Figure 1

【課題】タブレット等からの音声情報の音質を損なうことなく、かつ、緊急放送等を妨げることなく、簡易な操作で適宜音声情報の切り替えを可能とする。【解決手段】音声情報を出力する音声出力手段７０と、音声出力手段７０から音声出力可能に音声情報を集音する集音手段１０と、音声出力手段７０から音声出力可能であると共に、所望の音声情報を選択再生可能に予め格納する音声情報格納手段２０とを備え、集音手段１０から入力された音声情報を音声出力手段７０を介して音声出力する集音放送モードと、音声情報格納手段２０の所定の音声レベルが検知された場合に、格納された音声情報を音声出力手段７０を介して再生出力する再生放送モードとを具備し、再生放送モードにおいて、集音手段１０が選択された場合には、集音放送モードに切り替える。【選択図】図１
