# ARCADE: Arabic Radio Corpus for Audio Dialect Evaluation
ARCADE is a city-scale corpus of Arabic radio speech designed for fine-grained dialect identification. The dataset contains 6,907 annotations for 3,790 unique audio segments collected from radio streams spanning 58 cities across 19 Arab countries.
## Dataset Description
Each 30-second audio clip is annotated with:
- **City and Country**: Fine-grained geographic labels at the city level
- **MSA or Dialect**: Whether the speech is Modern Standard Arabic, dialectal, mixed, or not applicable
- **Emotion**: Speaker emotion (neutral, happiness, anger, etc.)
- **Audio Type**: Single speaker, multiple speakers, music/no speech, or Quran recitation
- **Keep or Skip**: Whether the clip is suitable for dialect modeling
- **Confidence**: Annotator confidence level (sure, unsure, no idea)
The filename alone is not a unique identifier and may appear across multiple cities. To obtain a unique key, concatenate the filename with the corresponding city name.
A detailed description of the dataset is provided in the accompanying paper: [https://arxiv.org/abs/2601.02209](https://arxiv.org/abs/2601.02209)
## Intended Uses
- Fine-grained Arabic dialect identification at the city level
- Sociolinguistic studies of regional speech variation
- Multi-task learning combining dialect, emotion, and speaker classification
- Robustness evaluation under domain and channel shift
## Dataset Statistics
- **Total annotations**: 6,907
- **Total unique audio segments**: 3,790
- **Cities**: 58
- **Countries**: 19
- **Clip duration**: 30 seconds
