Not effort - but data. A large amount of the dictation learning was done through users using and correcting the software. If you have 40,000,000 English users but only 80,000 Polish users you can immediately see why the software may not be up to par. Google Voice to Text, from my experiences, is bloody amazing for Chinese. My Chinese is abysmal (think "never gets the tone right") and for short phrases/sentences I've never had Google fail on me. Maybe it fails on larger sentences but it would be difficult for me to believe. Japanese is another language it does very well in. I can only count on one hand how many times it has made a mistake - and usually repeating myself a tad slower and with less slurring and it will pick it up just fine.
