Patent US 10,255,914

A portable communications device may include a transceiver configured to communicate with a network, a microphone configured to convert sounds into an audio signal, and a processor coupled to the microphone and the transceiver. The device may further include a memory coupled to the processor. The memory may include instructions that, when executed, cause the processor to convert an audio signal into a natural language request and initiate payment of a first account of a first domain-specific data source from funds available in a second account of a second domain-specific data source in response to the natural language request via the network. The instructions may further cause the processor to receive a confirmation of the payment from the network.
