Conlang Brainstorming: Tiiliitian and BFL-2 (Patreon)

Finally trying to figure out specific scripts for these two languages because I don't want the text in the background of this book to be gibberish. I'm terribly out of practice, the last time I did anything serious with conlang was in highschool. Nb4 someone asks, yes I did go back and add IPA, it's just that I don't have it memorized and it's so difficult to read that it's useless to me for fast transcription.

Tiiliitian is the most commonly spoken language in avian space, and it's the lingua franca of the Dominion of Tiiliit, a skimmer-majority colonialist monarchy. The reigning monarch is the Tiiliit (pictured). Avians have a syrinx and can produce two pitches simultaneously, and vowels in Tiiliitian can have up to 16 different tone structures. The base character of the vowel is modified for each of these tones, while consonants are relegated to diacritical marks.

BFL-2 or BFL-H (Bug Ferret Language - Hegemonic) is the most commonly spoken tactile sign language in bug ferret space. Most bug ferret languages are referred to in English as acronyms like this because they contain no sounds to transliterate into Roman characters. The numbering system for them goes roughly in order of when humans first encountered them, and ironically, the most commonly spoken ferret language was not the first language of the bug ferrets involved in first contact. The crew of workers who popped in near Jupiter to set up a wormhole gate spoke BFL-1, a dialect from their homeplanet's frigid subtropics with a much smaller speaker base. It's like if first contact with humans happened with a posse of humans who spoke Finnish.
