Hi,
I got no answer from VoxATC, but was told by another user that the AT&T Natural Voices he bought at NextUp were working. I thus finally decided to try, and bought AT&T Mel at NextUp. The voice works! The difference is Mel is a version 1.4 voice, while Mike & Crystal bought here are 5.1. I saw in a previous post that people having bought 1.4 voices could download version 5.1 for free.
Inversely, is it possible to get 1.4 after having bought 5.1?
Thank you.
Kind regards,
Miguel
