Observation 1: About me finding it horrible is my right and you have to be prepared to accept criticism, because my criticism is constructive and I ask you what is your experience here in Brazil?
You are NOW saying you have an issue with voices in Brazil.
In your first post, you made a blanket statement about voices being horrible and, since they obviously aren't, and there are many differences between each accent ( some of them are made with *real* native speakers of that region, others are text-to-speech ), I could only assume you only tried a very specific region and, the only one that sounds russian to me is..the russian one.
Portuguese IS one of the text-to-speech voices so yes, it's of a lower quality than the ones with real voices so, if you would like to volunteer to provide with real voice ( we would need male and female ), like other users have done, we'd be happy to replace the TTS ones.
You highlighted the "horrible" but not the "congratulations", strange for a big company like Fsdreamteam, you were uncomfortable with the constructive criticism but not the praise.
Fsdreamteam is an extremely small company, where it's possible to read a message and miss a bit.
