Whats most Realistic Text to Speech voice software?

Hey there, I'm just looking for something that sound smoother and not like a robot to drop in my videos here and there.
Think EDM girl announcer voice

I won't send any live links (sorry)

On naturalreaders with the plus plan ($20/Month) using the voice "English (US) - Guy" and speed set to 0 it sounds quite good.
Here is a link: www . naturalreaders.com/online/

Also, you might want to consider Amazon Polly where you pay I think $4 per million characters.
Here is a tutorial on how to use it: www . youtube.com/watch?v=XpQm-g1yMu8
An example, how it might sound like would be at 2:20

Furthermore, Google Cloud text-to-speech is quite powerful: cloud . google.com/text-to-speech
You can test it yourself if you scroll down a little bit on the website

Microsoft Azur does a great job as well, : azure . microsoft.com/en-us/services/cognitive-services/text-to-speech/
