@poisinivy, Thanks for the link to the MS Azure service I will have to check it out. I have also found one for AWS Polly that has a plug-in for UE4 that I may investigate too as I am using UE4 a lot at the moment.

I think the friend that helped me on my animation entry for the Xmas contest is likely to be wiling to help me in future and she sounds great... unlike me who did the rest of the voices!!! If she will help in future I really don't need to much more.

Anyway you can't beat a real voice but I am very impressed by how far they have come recently with AI text to speech so I will keep monitoring that and find an affordable option... although as you say for artists and hobbyists free is the most affordable :)
