1. A system comprising: one or more processors; a computer-readable memory; and a module comprising executable instructions stored in the computer-readable memory, the module, when executed by the one or more processors, configured to: obtain a voice recording and a corresponding sequence of speech units; select a first speech segment, wherein the first speech segment corresponds to a portion of the voice recording and wherein the first speech segment corresponds to a first speech unit; apply a first compression technique to the first speech segment to create a first compressed speech segment, wherein the first compression technique comprises one of time domain compression or perceptual compression; apply a second compression technique to the first compressed speech segment to create a second compressed speech segment, wherein the second compression technique comprises one of time domain compression or perceptual compression, and wherein the second compression technique is different from the first compression technique; distribute the second compressed speech segment to a client computing device for use in a text-to-speech system.
