⚒️ Model Description
Ethio-ASR is a suite of Automatic Speech Recognition (ASR) models for Ethiopian languages. This repo contains a monolingual Tigrinya ASR model based on wav2vec2‑bert-2.0, fine-tuned on the Tigrinya subset of the WAXAL Speech Dataset.
- Developed by: Ethio-ASR Team
- Task: Speech Recognition (ASR)
- Language: Tigrinya
- License: CC-BY-4.0
- Finetuned from: facebook/w2v-bert-2.0
📈 Evaluation on WAXAL Test Set (Tigrinya)

🎧 Direct Use
from transformers import AutoModelForCTC, AutoProcessor
import torchaudio, torch
processor = AutoProcessor.from_pretrained("badrex/Ethio-ASR-tigrinya")
model = AutoModelForCTC.from_pretrained("badrex/Ethio-ASR-tigrinya")
audio, sr = torchaudio.load("audio.wav")
inputs = processor(audio.squeeze(), sampling_rate=sr, return_tensors="pt")
with torch.no_grad():
logits = model(**inputs).logits
pred_ids = torch.argmax(logits, dim=-1)
transcription = processor.batch_decode(pred_ids)[0]
print(transcription)
🔧 Downstream Use
- Voice assistants
- Accessibility tools
- Research baselines
🚫 Out‑of‑Scope Use
- Languages other than Tigrinya
- High‑stakes deployments without human review
- Noisy audio without speech enhancement
⚠️ Risks & Limitations
Performance might vary across dialects, genders, ages, and recording quality.
