I'm just wondering if there's any TTS engine that may be trained with reading control sentences on the correct pronunciation and expression of words.
The end goal being a voice that doesn't sound simulated or robotic.
If you don't know of any, do you know why they don't exist?
Edit: Ideally it would be English, free, but up to 100 AUD would be acceptable and operating Windows or Linux.
Current programs I'm aware of include: Textaloud, NaturalReader and online Ivona and Acapela-group.
