Here are the rules for my (in-universe conlang) anarcho-syndicalist language with Lakes Plain phonology and root and template morphology. I imagine that the world in which this is spoken has a sort of reverse/sideways fundamentalist ideology that believes strongly to the point of being an unexamined premise that each ideology can only be expressed in a language specifically designed for it. So lots of new languages, in all of whom translation from it and translation into it is fundamentally impossible and almost certainly a cause of offense because of the ideological differences! I have cycled through several possibilities, but this seems to be the most stable phonemic set of rules. Comments nonetheless welcome. UnVoiced consonants (P, T, K) 1. Voiceless Consonants become plosives (p, t,k) a. If the radical is geminate b. As the onset of a non-initial syllable c. As the coda of a final syllable 2. Voiceless consonants become fricatives (f,s, h < x) a. As the onset of the initial syllable b. As the coda of a syllable if the onset of the next syllable is a voiceless plosive. 3. Voiceless consonants become voiced fricatives (v,z, y < ɣ) a. As the coda of a syllable if the onset of the next syllable is voiced. Voiced consonants (B, D) 1. Voiced consonants become plosives (b, d) a. If the radical is geminate b. As the onset of a non-initial syllable c. As the coda of a final syllable 2. Voiced consonants become 'liquids' (w,r) a. As the onset of an initial syllable b. As the coda of a syllable no matter what the voicing of the onset of the next syllable BUT 3. Voiced consonants become nasals (m,n) a. If the voiced consonant is the onset or coda of a syllable containing /a/ [ã] b. If the voiced consonant is a geminate radical where either the onset or the coda or both adjacent to the radical contains /a/ The craziest idea which I rejected was a devoicing of the Voiced plosives in word final position so that a final voiceless plosive reflected a voiced plosive in the root and pattern morphology but a voiceless plosive elsewhere. Final voiceless plosives in this scheme became voiceless fricatives, so no confusion in the final position, but potentially too confusing to even native speakers.
