So there are voiced/voiceless stops and fricatives in many languages, but I'm wondering if there are the same sort of voiced/voiceless distinctions for nasals / approximants / trills / flaps / affricates / vowels / etc.
Then I am wondering what they sound like. A voiceless "r" sounds still like an "r", while a voiceless "z" sounds like an "s", a different letter. Maybe that is just because of my background. So wondering if other languages have the feature of the above letters being contrasted with their voiced equivalents (and what some of the languages are for more info). I have seen just a few languages with perhaps [w̥], but I don't think I've seen any with voiceless vowels, while many seem to have nasal vowels.
So to summarize, I am looking for:
- Languages that have any of the above as voiceless versions. Primarily [l̥], [ɹ̥], [n̥], [m̥], [ʁ̥], [ŋ̊], or any of the vowels. To me these just sound like whispered versions of the sounds, as opposed to s/z which sound like different sounds.
- Languages which contrast any of the above listed voiceless sounds with their related voiced sound. By contrast I just mean they use both in constructing their words. This is the bigger part of the question.
