12. A computing device, comprising: at least one processor; a memory device including instructions operable to be executed by the at least one processor to perform a set of actions, configuring the at least one processor to: receive a first text-to-speech (TTS) request including a representation of first text; process the representation of first text using a first voice corpus to produce a first TTS output; send the first TTS output to a first device; store the representation of the first text; process the representation of first text using a second voice corpus to produce a second TTS output, the second voice corpus being different from the first voice corpus; store the second TTS output; receive a second TTS request including a representation of second text; compare the representation of second text to the representation of first text; and determine a third TTS output using at least a portion of the second TTS output, the third TTS output corresponding to the representation of second text.
