Abstract: A message selection system may include a memory device to store a plurality of messages. Each message may prompt a user to provide a respective predetermined response. The message selection may further include a processor in communication with the memory device. The processor may determine at least one condition associated with a channel configured to transmit the plurality of messages to a user interface. The processor may further select, in response to the at least one condition associated with the channel, at least one of the plurality of messages to be transmitted to the user interface over the channel. A method and computer-readable medium may also be implemented in message selection.
