I am writing to ask if anyone knows of a good book that either in whole or part provides an overview of the history of speech-generating software and/or devices - essentially, a history of humans making computers "talk."

For background, my dissertation is primarily a qualitative study of how US parents of young non-verbal children with developmental disabilities incorporate the iPad into their families' lives when the child uses the mobile device partly or primarily as a speech-generating system.  I am pairing this fieldwork with archival research on how parents have historically navigated the world of personal computers equipped with software for producing synthetic speech.
