The invention provides a voice alarm circuit, a voice alarm device and a voice alarm system, wherein the voice alarm circuit comprises a control module and a voice broadcast module. The control modulecomprises a signal recognition unit and a logic signal triggering unit, the signal recognition unit recognizes a steering signal, a reversing signal and a vehicle lamp signal, and the logic signal triggering unit triggers the voice broadcasting module to work according to a corresponding mode according to the recognized signals; the voice broadcast module comprises a voice chip, a power amplification unit and a loudspeaker, wherein the voice chip receives a trigger signal sent by the logic signal trigger unit and sends a voice signal to the loudspeaker through the power amplification unit. The voice alarm circuit can selectively work according to a low-speed alarm mode according to the vehicle speed condition, and meanwhile, can distinguish daytime from night and work according to a corresponding mode. During broadcasting, an alarm is given in a buzzing and voice combined mode, and a better prompting and alarming effect is achieved.
本发明提供一种语音报警电路、语音报警器以及语音报警系统，其中，语音报警电路包括：控制模块以及语音播报模块；控制模块包括：信号识别单元以及逻辑信号触发单元，信号识别单元识别转向信号、倒车信号以及车灯信号，逻辑信号触发单元根据识别的信号，触发语音播报模块按照对应模式进行工作；语音播报模块包括：语音芯片、功率放大单元以及扬声器，语音芯片接收逻辑信号触发单元发送的触发信号，并经功率放大单元发送语音信号至扬声器。本发明的语音报警电路能够根据车速情况，选择性按照低速报警模式进行工作，同时可区分白天和黑夜，并按照对应的模式进行工作。播报时，采用蜂鸣和语音结合的方式进行报警，具有更好的提示报警效果。
