A method, computer program product, and a system where a processor(s) continuously obtains, from devices in a group of devices within a defined geographic proximity to each other, processing requests. Each request is a result of a device in the group of devices receiving and interpreting a voice command issued within a geographic area comprising the group of devices. The processor(s) buffers, in a memory resource, a portion of the processing requests obtained within a defined time interval. The processor(s) determines there are duplicate processing requests in the portion. Based on determining there are duplicates, the processor(s) rejects the duplicates. The processor(s) selects a specific device to execute each processing request from the devices where the request and the duplicates of that request originated. The processor(s) utilize the specific device to execute the processing request.
