I frequently use voice recognition on my phone. It's faster than thumb typing. When I moved to Zürich, the voice recognition had a terrible time with local place names. It's improved over time, but I'm pretty sure that it improved by flipping an internal flag somewhere that said "Try English, German, and French words in no particular order". The consequences are interesting, and not always an improvement. For example, yesterday, I said, "I was not feeling well today." My phone's voice recognition parsed it as, "iOS Nacht Frühling Welt zu die."
