# DACS: Dialectal Arabic Code-Switching Dataset

This release includes **2 hours of annotated Egyptian Arabic speech** from the **ADI-5 development split** in the **MGB-3 Challenge**.

## Overview

Unlike the original **MGB-3:EGY** data, this corpus has been **manually segmented** into smaller utterances based on pauses of **≥500 ms of silence**.  
Each utterance has been **verbatim transcribed** by a lay **native Egyptian speaker**.

The released MGB-3 data includes both **speech features** and **textual features** extracted from ASR transcriptions.

## Annotation Details

The transcribed data was further **annotated for word-level Code-Switching (CS)** by **three independent annotators**.  
Following the guidelines described in the associated paper, each word was classified into one of the following four categories:

- **MSA** — Modern Standard Arabic word with MSA pronunciation  
- **EGY** — Egyptian dialect word  
- **MIX** — MSA word with dialectal pronunciation  
- **FRN** — Foreign word (i.e., non-Arabic)

An additional tag **NULL** was used for unintelligible words or those that could not be categorized into any of the four labels.
