AI Models for Endangered Language Revitalization
We’re building a small speech corpus (<40 hours) for a severely endangered language. We want to leverage open‑source ASR + LLMs for community learning tools without leaking sacred narratives. Strategies for balancing openness and cultural data sovereignty?
Don’t forget reversible obfuscation of speaker identity (voice conversion toward a neutral timbre) before any cloud processing. Protects elders from having their voice cloned later.
Partition corpora: public pedagogical phrases vs. restricted ceremonial sets. Fine‑tune acoustic model on all audio locally, but only release weights trained on the open subset. Keep a reproducible script so outsiders can re‑train if they gain clearance.
