1. A method for text-to-speech synthesis, comprising: receiving, at a first device, incidental audio speech data over a first network communication link from a second device, wherein the incidental audio speech data is produced during an audio communication in which an operator of the second device participates and is representative of the operator's speaking characteristics; generating, by the first device, a voice dataset for the operator based, at least in part, on the incidental audio speech data; receiving, at the first device, text data from the second device over a second network communication link subsequent to receiving the incidental audio speech data; converting, by the first device, the text data to synthesized speech; and personalizing the synthesized speech to sound like the operator using, at least in part, the voice dataset.
