The invention relates to a voice broadcasting method, a vehicle-mounted horn, a vehicle-mounted terminal and a vehicle. The method comprises the following steps: a vehicle-mounted horn responds to a broadcast request sent by a vehicle-mounted terminal and sends an authorization code to the vehicle-mounted terminal; receiving a first ciphertext generated by the vehicle-mounted terminal according to the authorization code; generating a second ciphertext according to the authorization code; if the first ciphertext is consistent with the second ciphertext, sending a first broadcast password to the vehicle-mounted terminal; receiving a second broadcast password and broadcast content sent by the vehicle-mounted terminal; and if the first broadcast password is consistent with the second broadcast password, performing voice broadcast according to the broadcast content. Thus, a plurality of vehicle terminals can carry out voice broadcasting through the same vehicle-mounted horn, sharing use of the vehicle-mounted horn in the vehicle is achieved, and repeated broadcasting devices do not need to be installed in the vehicle. Meanwhile, it can be ensured that the broadcast content comes from the correct vehicle-mounted terminal, and the accuracy of voice broadcast is ensured.

    本公开涉及一种语音播报方法、车载喇叭、车载终端和车辆。该方法包括:车载喇叭响应于接收到车载终端发送的播报请求,向车载终端发送授权码;接收车载终端根据授权码生成的第一密文;根据授权码,生成第二密文;若第一密文和第二密文一致,则向车载终端发送第一播报密码;接收车载终端发送的第二播报密码和播报内容;若第一播报密码和第二播报密码一致,则根据播报内容进行语音播报。如此,可以使得多个车辆终端能够通过同一个车载喇叭进行语音播报,实现车辆中车载喇叭的共享使用,无需车辆中安装重复的播报装置。同时可以确保播报内容来自正确的车载终端,保证语音播报的准确性。
