Had a weird phoneme dream last night. Someone was trying to get me to pronounce their name for me, and they were sounding it out one piece at a time. One of these sounds was somehow in between an "L" and a "Th" sound, and the harmonics were very pronounced like a tuvan throat singer. My dream-brain kept on wanting to randomly label it "ï" for some reason, so it might have been a vowel too. Not convinced this is a valid phoneme (at least for human physiology).
