+ # NLLB-200 Mooré LoRA (600M)
20
+
21
+ LoRA adapter for `facebook/nllb-200-distilled-600M` fine-tuned on ~205k cleaned Mooré↔French/English sentence pairs, all four directions (`eng_Latn↔mos_Latn`, `fra_Latn↔mos_Latn`).
22
+
23
+ Part of [Mooré-Voice](https://github.com/Rekin226/Moore-Voice) — open translation
24
+ and speech recognition for Mooré (Mòoré / Mossi, ISO 639-3 `mos`), spoken by
25
+ ~8 million people in and around Burkina Faso.
26
+
27
+ ## Evaluation
28
+
29
+ | Model | Direction | BLEU | chrF++ |
30
+ |---|---|---:|---:|
31
+ | zero-shot base | `eng_Latn→mos_Latn` | 2.94 | 20.5 |
32
+ | zero-shot base | `fra_Latn→mos_Latn` | 2.54 | 20.37 |
33
+ | zero-shot base | `mos_Latn→eng_Latn` | 8.71 | 29.01 |
34
+ | zero-shot base | `mos_Latn→fra_Latn` | 7.04 | 26.49 |
35
+ | fine-tuned | `eng_Latn→mos_Latn` | 3.19 | 21.82 |
36
+ | fine-tuned | `fra_Latn→mos_Latn` | 3.1 | 22.01 |
37
+ | fine-tuned | `mos_Latn→eng_Latn` | 8.92 | 30.13 |
38
+ | fine-tuned | `mos_Latn→fra_Latn` | 8.32 | 29.16 |
39
+
40
+ ## Training data
41
+
42
+ Curated corpus v0.1 (see repo `data/CORPORA.md`): MT560 (Bible-register, ~89%), community instruction pairs, NLLB-mined bitext (LASER ≥ 1.15), translatewiki. Detokenised, LID-gated, FLORES-decontaminated. FLORES-200 devtest held out for eval.
43
+
44
+ ## Limitations
45
+
46
+ - Register skew: mostly religious text → weaker on administrative/technical register.
47
+ - Mooré orthography follows the 1976/2003 standard as used by the source corpora; diacritic usage varies upstream.
48
+ - Not human-evaluated yet; BLEU/chrF++ on FLORES only.
49
+
50
+ ## License note
51
+
52
+ Released **CC-BY-NC-4.0** because a large share of the training text derives
53
+ from sources whose redistribution terms are research-use-only or undeclared
54
+ (see the repo's `data/CORPORA.md` / `data/AUDIO_CORPORA.md`). A fully
55
+ permissive release is planned once the corpus is rebuilt on cleared sources
56
+ (Common Voice `mos` + translatewiki + NLLB-mined).
