The problem is that they are dishonest about the quality of the voices. The quality of the test samples of the voices on they have on their web page is significantly better than what you get once the Voice generates audio on your mobile device. I believe they are either using highet quality commercial voices not available on the play store or they use some server AI supported engine to process the sample or they manually clean out the samples in the lab. Misleading. Only William is worth it.
The voice is good. But in 6 months of usage, I still don't find it superior in any way to Google's. It's not inferior either, but why bother having such a large pack with no obvious improvement? Maybe a specialist would notice something different. Or not. For the end user there is nothing better, just more of the same.
