Arabic Whisper Multi-Dialect ASR Dataset

A comprehensive multi-dialect Arabic speech recognition dataset prepared for Whisper model fine-tuning.

Dataset Description

This dataset combines high-quality Arabic speech data from multiple dialects, specifically curated for fine-tuning OpenAI's Whisper models on Arabic speech recognition tasks.

Dialects Included

• Modern Standard Arabic (MSA) - Formal Arabic used in media and formal contexts
• Egyptian Arabic (EGY) - The most widely understood Arabic dialect
• Gulf Arabic (GULF) - Arabic dialects from the Gulf region

Dataset Statistics

• Total Samples: ~105,000 audio-text pairs
• Train Split: ~94,500 samples (90%)
• Validation Split: ~5,250 samples (5%)
• Test Split: ~5,250 samples (5%)
• Audio Format: 16kHz, mono
• Text: Normalized Arabic script

Source Datasets

This dataset is a combination of the following sources:

1. MightyStudent/Egyptian-ASR-MGB-3 - Egyptian dialect broadcast data
2. MAdel121/arabic-egy-cleaned - Cleaned Egyptian Arabic speech
3. Nourhann/filtered_common_voices_16khz - Modern Standard Arabic
4. badrex/arabic-speech-SADA22-Khaliji - Gulf dialect speech (30% sample)

Dataset Structure

DatasetDict({
    train: Dataset({
        features: ['audio', 'sentence'],
        num_rows: ~94500
    })
    validation: Dataset({
        features: ['audio', 'sentence'],
        num_rows: ~5250
    })
    test: Dataset({
        features: ['audio', 'sentence'],
        num_rows: ~5250
    })
})

Data Fields

• audio: Audio file (16kHz sampling rate)
• sentence: Transcription text in Arabic
• dialect: Dialect label ('msa', 'egy', or 'gulf')

Usage

Loading the Dataset

from datasets import load_dataset

dataset = load_dataset("MadLook/arabic-whisper-multidialect")

print(dataset)
# Access splits
train_data = dataset['train']
val_data = dataset['validation']
test_data = dataset['test']

Fine-tuning Whisper

from transformers import WhisperProcessor, WhisperForConditionalGeneration

# Load model and processor
processor = WhisperProcessor.from_pretrained("openai/whisper-small", language="Arabic", task="transcribe")
model = WhisperForConditionalGeneration.from_pretrained("openai/whisper-small")

# Prepare dataset
def prepare_dataset(batch):
    audio = batch["audio"]
    batch["input_features"] = processor.feature_extractor(audio["array"], sampling_rate=audio["sampling_rate"]).input_features[0]
    batch["labels"] = processor.tokenizer(batch["sentence"]).input_ids
    return batch

dataset = dataset.map(prepare_dataset)

# Continue with training...

Data Processing

The dataset has been processed with the following steps:

1. Audio normalization: All audio resampled to 16kHz mono
2. Text normalization: Arabic text normalized (diacritics removed, Alef forms unified)
3. Dialect balancing: Datasets sampled to ensure balanced representation
4. Quality filtering: Low-quality samples removed
5. Train/Val/Test split: 90/5/5 split with shuffling

Intended Use

Primary Use Cases

• Fine-tuning Whisper models for Arabic ASR
• Multi-dialect Arabic speech recognition research
• Arabic speech technology development
• Dialect-aware speech recognition systems

Considerations

• This dataset combines multiple dialects; consider dialect-specific fine-tuning if needed
• Text is normalized and may not preserve dialectal spelling variations
• Dataset is balanced across dialects but individual dialect performance may vary

Limitations

• Gulf dialect representation is lower (30% of original dataset)
• No code-switching samples included
• Limited to broadcast and read speech domains
• May not generalize well to conversational or noisy speech
