⚒️ Model Description

Ethio-ASR is a suite of Automatic Speech Recognition (ASR) models for Ethiopian languages. This repo contains a monolingual Amharic ASR model based on wav2vec2‑bert-2.0, fine-tuned on the Amharic subset of the WAXAL Speech Dataset.

Developed by: Ethio-ASR Team
Task: Speech Recognition (ASR)
Language: Amharic
License: CC-BY-4.0
Finetuned from: facebook/w2v-bert-2.0

🎧 Direct Use

from transformers import AutoModelForCTC, AutoProcessor
import torchaudio, torch

processor = AutoProcessor.from_pretrained("badrex/Ethio-ASR-amharic")
model = AutoModelForCTC.from_pretrained("badrex/Ethio-ASR-amharic")

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)

🚫 Out‑of‑Scope Use

Languages other than Amharic
High‑stakes deployments without human review
Noisy audio without speech enhancement

⚠️ Risks & Limitations

Performance might vary across dialects, genders, ages, and recording quality.
