Here's a thing I've started that may be of interest ... I'm going through the World Atlas of Language Structures ( https://wals.info/ ) and trying to figure out the values of features for my languages. Mainly I'll be focusing on Jarda, Tirėlat, and Lindiga, but I'll be adding data from other languages as well. At least for now I'll be limiting it to Azirian "natlangs" (as opposed to conlangs that are actually in-world conlangs like Jaghri and Minza, without native speakers). I'm not sure of many of the values for some of the features, but I'll try to give tentative values for them if I don't know. I'll start with the first 5 features, all having to do with phonology. The first few features are easy ones, starting with the size of the consonant inventory. 1. Consonant Inventories https://wals.info/chapter/1 Small 1 (Zirinka) Moderately small 3 (Mayushi, Vizaki, Yasaro) Average 2 (Lindiga, Tirėlat) Moderately large 2 (Jarda, Zharranh) Large 0 I have more languages in the "moderately small" category than "average", but this is such a small sample that it doesn't say much ... it looks like a reasonable distribution. Next the vowel quality inventory. This doesn't count long, short, or nasalized vowels as different, just the distinctions in vowel height, backness, and rounding. 2. Vowel Quality Inventories https://wals.info/chapter/2 Small 2 (Vizaki, Zirinka) Average 3 (Mayushi, Yasaro, Zharranh) Large 3 (Jarda, Lindiga, Tirėlat) The third feature is the ratio of these two numbers. 3. Consonant-Vowel Ratio https://wals.info/chapter/3 Low 0 Moderately low 1 (Lindiga) Average 6 (Jarda, Mayushi, Tirėlat, Vizaki, Yasaro, Zirinka) Moderately high 1 (Zharranh) High 0 It seems that I have an overabundance of "average" consonant/vowel inventories and not many on the extremes. Again it's a small sample, but I'd expect around 3-4 in the "average" category rather than 6. 4. Voicing in Plosives and Fricatives https://wals.info/chapter/4 No voicing contrast 2 (Lindiga, Yasaro) Plosives alone 1 (Mayushi) Fricatives alone 2 (Vizaki, Zirinka) Both 3 (Jarda, Tirėlat, Zharranh) The unusual result here is the high number of languages with voicing contrast in fricatives alone. This could be an artifact of the small sample size, but I think that Azirian languages in general may have more fricatives than typical human languages. I'd also expect more languages with a contrast in plosives alone, but again it's a small sample. 5. Voicing and Gaps in Plosive Systems https://wals.info/chapter/5 Other 4 (Lindiga, Vizaki, Yasaro, Zirinka) /p t k b d g/ 2 (Jarda, Tirėlat) Missing /p/ 0 Missing /g/ 1 (Zharranh) Both missing 1 (Mayushi) "Both missing" is a rare category in WALS (only 3 out of 567 languages), so it's interesting that Mayushi fits into this category. The languages in the "other" category lack a voicing contrast in plosives.
