The disclosure is directed to a voice-controlled Bluetooth headset, which includes a receiver, a storage module, an offline voice recognition module, and a Bluetooth module. The offline voice recognition module is used to activate and recognize a preset voice when a preset activation password is received. The Bluetooth module is electrically connected to other modules, and is used for system control, Bluetooth transmission, and processing of instructions output by the preset voice recognition module and performs corresponding functions. With the above structure, the present disclosure can implement voice control of the Bluetooth headset according to a simple preset password, without manual operation, and is simple and convenient to use. The offline voice recognition module can achieve a preset voice control effect by setting a simple preset password, reducing the time required for the voice recognition device to recognize complex voice information, and the user's human-machine interaction experience is better, which further saves the cost required for voice recognition devices.
