I’ve tested all three voices supplied with maryTTS bundle. The two German voices at 16kHz are rendered correctly as well as the English one at 48kHz. So from my point of view all fine

I tested it with (Build #920) version 2.1.0.201705151816 | MaryTTS Voice Service, but both german voices are too fast, and english voice is like a bit on Valium (a bit too slow). I’ve tested it directly on OH2-Server (System Speaker with mp3 support), it’s ok (all voices)!!! But when I select my “Allplay speaker” ->‘Default Sink’ in audio configuration, speed didn’t fit… Is it an Allplay problem or a MaryTTS problem?
