What about other products which include TTS (Text To Speech) functions?

Is it possible that the writer's guild is looking at a potential revenue loss on their own audio book retail?
Everyone and their dog (service dog or not) seems to be coming out with some type of TTS solution. Some of the voices are actually very good and the speech engines are constantly making improvements.
Sounds like another business mdel that failed to transition into the modern age.
