The language detection failed to work (it identified it as tr-TR) with these words for Slovene: jabolko hruška sliva marelica drevo dež mleko malo preveč majhno veliko

This works perfectly on the first result on Google for "language identification", however: https://open.xerox.com/Services/LanguageIdentifier

Edit: I now see Slovene is not supported, apologies are in order.
