Voice(s) were last removed feb 19th.
Speech & Insights were ‘normal’ too at the time.
But I now know what happened. I tried voice Lotte and deleted Ruben. But the English voice was suddenly present…?
It turns out it gets downloaded when you switch Homey’s language.
And of course it doesn’t get deleted if you switch back❌ , not even a notification here…
So speech takes 175MB now.
I decided to delete all my apps, did a recovery & full software download, but wtf…
So, dayum, why not do a factory reset and backup restore and hey, things are quite average now 
I experiment a lot with Homey, maybe I should start from scratch one day
