## Prompt taxonomy (L0–L6)

Each level adds exactly one contextual signal; everything else is held constant. Output is always
required in the native script of the target language.

| Level | Context added |
|---|---|
| **L0** | None — bare transcription instruction, no language hint |
| **L1** | Target language specified (baseline) |
| **L2** | + structured domain metadata (style, region, one-line domain description) |
| **L3** | + natural-language audio description |
| **L4** | + domain entity list in **English** script |
| **L5** | + the same domain entity list in **native** script |
| **L6** | + an entity list from an **unrelated** domain (adversarial control) |

## Loading

Each language is a split (with playable, embedded audio):

```python
from datasets import load_dataset

ds = load_dataset("SakshiJ/IndicContextEval", split="Hindi")   # Bengali, Telugu, ...
print(ds[0]["audio"], ds[0]["l5_prompt"])                       # audio decoded automatically
```
