Egyptian Arabic ASR Clean 72 h

Dataset Summary

This corpus contains ≈72 h of Egyptian‑Arabic speech aligned to text.
Audio has been resampled to 16 kHz mono WAV, transcripts are normalised Arabic (no diacritics, Tatweel, digits verbalised), and the data are split 80 / 10 / 10 into train / validation / test.

Supported Tasks and Leaderboards

Task	Tags	Notes
Automatic Speech Recognition	`asr`, `speech-recognition`	Primary use‑case
Forced Alignment / VAD	`alignment`, `vad`	Clips ≤ 25 s

Languages

The dataset is predominantly Egyptian Arabic (ar‑EG).
~85 % of recorded hours are male speakers; speaker IDs are unavailable.

Data Collection and Processing

Format Unification – convert all audio to 16 kHz WAV.
Deduplication – drop exact audio/text duplicates; remove nulls.
Metadata Pruning – retain only core fields.
Text Normalisation – strip diacritics, Tatweel, punctuation, Latin letters; verbalise digits; fix common glyph errors; run CAMeL‑Tools morphology checks.
Alignment Diagnostics – compute chars/s and words/s; flag extreme values.
Duration Filtering – keep clips 0.5–25 s.
Shuffle & Split – 80 / 10 / 10 random split, uploaded as datasets.DatasetDict.

Usage Example

from datasets import load_dataset

ds = load_dataset("your-username/egyptian_arabic_asr_clean72h")
print(ds["train"][0]["audio"].sampling_rate)  # 16000
print(ds["train"][0]["text"])
