Problem Statement

Standard Arabic speech recognition systems perform poorly on Egyptian Arabic due to significant phonological and lexical differences. Egyptian Arabic lacks standardized orthography, making transcription particularly challenging.

Solution

Fine-tuned Whisper on a curated Egyptian Arabic speech dataset with custom data preprocessing for dialect-specific phonetic patterns. Implemented post-processing rules for handling code-switching between Arabic and English.

Key Features

  • Whisper model fine-tuned on Egyptian Arabic
  • Custom audio preprocessing pipeline
  • Code-switching detection and handling
  • Speaker diarization support
  • Real-time transcription capability
  • Evaluation metrics for dialect-specific accuracy

Challenges

  • Limited labeled data for Egyptian Arabic dialect
  • Handling code-switching between Arabic and English
  • Varied recording quality in training data
  • Non-standardized orthography for dialect transcription

Results & Metrics

30% improvement in WER over base Whisper for Egyptian Arabic

Robust handling of common code-switching patterns

Real-time transcription with acceptable latency

Successful evaluation on diverse Egyptian Arabic speakers

Lessons Learned

  • 💡Domain-specific fine-tuning of large speech models yields significant accuracy gains
  • 💡Data quality matters more than data quantity for low-resource languages
  • 💡Post-processing rules can significantly improve transcription quality
