# 🎤 FonBench — ASR Benchmark and Adaptation for Fon
|
| 16 |
+
|
| 17 |
+
Interactive leaderboard comparing six pre-trained multilingual ASR models on the **Fon language** (low-resource tonal language of Benin, ~8M speakers), and four adaptation strategies (LoRA and full fine-tuning) on the best model.
|
| 18 |
+
|
| 19 |
+
## 📊 Phase 1 — Zero-shot evaluation
|
| 20 |
+
Six state-of-the-art multilingual ASR models evaluated without adaptation: **MMS-1b**, **XLSR-53**, **OmniASR-CTC**, **AfriHuBERT**, **SeamlessM4T**, **Whisper-small**.
|
| 21 |
+
|
| 22 |
+
## 🏆 Phase 2 — Adaptation
|
| 23 |
+
Two adaptation strategies (**LoRA** at ranks 8 and 32, **Full Fine-Tuning** at LR 1e-5 and 5e-5) applied to the best zero-shot model.
|
| 24 |
+
|
| 25 |
+
**Best result: WER 19.27% (Full Fine-Tuning, LR 5e-5) — a 64-point improvement over zero-shot.**
