Voice input works really well for people speaking English with a Swedish accent. I think the accent of most educated Swedes is mostly a case of prosody. For sure there are some sounds we say slightly differently than native English speakers. We often have some trouble with /s/ and /z/, but I don't know, "war and peace", I think that's easily understood.

Source: voice typing this with Swedish vocal chords, and only had to correct "different lives" to "differently", and add /[^\w\s]/.

I understand completely. You don't want to know what the machine produced, when I asked it for "a new display".
