In some embodiments, the device management component 114 may control hotspot device 106, vehicle 122, or camera 124 to broadcast an audio message. The audio message may include a greeting message and a warning message. For example, once a trip is started a voice message could be broadcasted, such as a thanks for choosing the transportation service. In some embodiments, a warning message may warn passengers that a camera is on board. In some embodiments, the audio message may provide the driver with instructions for handling the incident. In some embodiments, the warning message may be broadcast in response to the activation of the trigger device. The broadcast audio message may deter incidents and improve the safety experience for both the driver and the passenger. In some embodiments, the device management component 114 may control hotspot device 106, vehicle 122, or camera 124 to capture audio data. For example, a two way communication channel may be opened.
