# MegaBNSpeech Test Data

To evaluate the performance of the models, we used four test sets. Two of these were developed as part of the MegaBNSpeech corpus, while the remaining two (Fleurs and Common Voice) are commonly used test sets that are widely recognized by the speech community.

## Use dataset library:
```python
from datasets import load_dataset
dataset = load_dataset("hishab/MegaBNSpeech_Test_Data")
```
