Update: I built two speech models on top of this 0-param substrate — tokenizer-free
STT + TTS (HoLo-ToLk). Short version: substrate + a spectral lens beats a mel baseline
on STT (CER 0.194 vs 0.213, multi-seed); TTS is a tokenizer-free single-speaker
feasibility demo. Full writeup + combined demo here: [New Post]
