Scraped 179k parallel Mien sentences from bibles, dictionaries, JW publications, and literacy projects. Cleaned, deduplicated, and aligned to the unified Latin orthography.
Learn Iu Mien (also spelled Lu Mien or Mienh waac), a Hmong-Mien language with around 800,000 first-language speakers across China, Vietnam, Laos, Thailand, and the diaspora. This site is the centralized home for it: a free neural translator scoring chrF 62 ium→eng, a 4,672 entry community dictionary, and a 20 level interactive course.
chrF scores how close a translation is to a human one — 0 unrelated, 100 identical. Even human translators cap near 80, since everyone phrases things differently.
Read the bars from short to long. Longer is better.
Our v7 model lands at 62: fluent enough to read for meaning, occasional small errors, clearly past every published baseline for Mien.
Scraped 179k parallel Mien sentences from bibles, dictionaries, JW publications, and literacy projects. Cleaned, deduplicated, and aligned to the unified Latin orthography.
Fine tuned Meta's NLLB 1.3B over seven iterations with LoRA on a single A30 GPU. Each pass corrected the weak spots from the last.
Scored chrF and BLEU on a held out test set. The v7 model lands at chrF 62 ium → eng — past the threshold for fluent translation.

Free forever. No ads. The goal is one centralized curriculum the whole community can lean on.
