# Igbo ASR - Whisper Small

A state-of-the-art automatic speech recognition (ASR) model for the Igbo language, fine-tuned on Whisper Small architecture. This model was powered by **Awarri Technologies** and an initiative of the **Federal Ministry of Communications, Innovation and Digital Economy** to advance indigenous language technologies and promote digital inclusion.

## Model Description

- **Model Name:** Igbo-ASR-v1.0
- **Architecture:** Whisper Small (244M parameters)
- **Language:** Igbo (ig)
- **License:** [other]
- **Model Size:** ~244M parameters

## Training Data

- **Training Time:** 120 hours
- **Data Sources:**
  - Langeasy platform recordings from speakers across Nigeria's 6 geopolitical zones
  - Publicly available datasets
- **Geographic Coverage:** All 6 geopolitical zones of Nigeria

## Quick Start

### Installation

```bash
pip install torch torchaudio transformers librosa
```

### Basic Usage

```python
from transformers import pipeline
import librosa

# Initialize the ASR pipeline
asr = pipeline("automatic-speech-recognition", model="NCAIR1/Igbo-ASR")

# Load audio file (16kHz recommended)
audio, sr = librosa.load("your_igbo_audio.wav", sr=16000)

# Transcribe
result = asr(audio)
print(result["text"])
```

### Advanced Usage

```python
from transformers import WhisperProcessor, WhisperForConditionalGeneration
import torch
import librosa

# Load model and processor
processor = WhisperProcessor.from_pretrained("NCAIR1/Igbo-ASR")
model = WhisperForConditionalGeneration.from_pretrained("NCAIR1/Igbo-ASR")

# Process audio
audio, sr = librosa.load("audio_file.wav", sr=16000)
input_features = processor(audio, sampling_rate=sr, return_tensors="pt").input_features

# Generate transcription
with torch.no_grad():
    predicted_ids = model.generate(input_features)
    transcription = processor.batch_decode(predicted_ids, skip_special_tokens=True)
    
print(transcription[0])
```

## Use Cases

### ✅ Recommended Applications
- Academic research on Igbo linguistics
- Educational tools for Igbo language learning
- Accessibility applications for hearing-impaired Igbo speakers
- Cultural preservation and documentation
- Voice-enabled applications for Igbo speakers
- Media and broadcast transcription
- Government services requiring Igbo language support

### ❌ Not Recommended
- Mass surveillance or unauthorized monitoring
- High-stakes applications without human oversight (legal, medical)
- Applications that could discriminate based on dialectal variations

## Limitations

- **Dialectal Coverage:** Some regional dialects may have varying accuracy levels
- **Code-Switching:** Reduced performance when mixing Igbo with English
- **Audio Quality:** Performance degrades with poor audio quality or excessive noise
- **Children's Speech:** Limited training data for younger speakers
- **Domain-Specific Content:** May require fine-tuning for specialized domains

## Model Details

### Technical Specifications
- **Architecture:** Transformer-based (Whisper Small)
- **Parameters:** 244M
- **Input:** Audio waveform (16kHz recommended)
- **Output:** Igbo text transcription
- **Context Length:** 30 seconds maximum per inference

### Training Details
- **Base Model:** OpenAI Whisper Small
- **Fine-tuning Framework:** PyTorch with Hugging Face Transformers
- **Geographic Representation:** All 6 geopolitical zones of Nigeria
- **Training Duration:** 120 hours

## Fine-tuning

For domain-specific applications, this model can be further fine-tuned:

```python
from transformers import WhisperForConditionalGeneration, Seq2SeqTrainer

# Load base model
model = WhisperForConditionalGeneration.from_pretrained("NCAIR1/Igbo-ASR")

# Fine-tune with your domain-specific Igbo data
# Recommended: 10-20 hours of high-quality domain audio
```

## Ethical Considerations

- Designed to promote equitable access to speech technology for Igbo speakers
- Users should consider cultural sensitivity when deploying the model
- Continuous monitoring for bias and performance variations is recommended
- Should not be used for surveillance or applications that could harm individuals
