The most common mistakes I've noticed is he tends to pronounce u's as &quot;oo&quot; instead of &quot;uh&quot; like in Au&eth;un, s&iacute;num and urmul (wish I knew more about phonology so I wouldn't have to give a grug-tier explanation but bear with me) and he has some issues with double consonants, either pronouncing them too forcefully (often with words containing tt) or too softly (like the kk in &quot;ekki&quot;)
