# Regional bengali text to IPA transcription - byT5-small

## A word of caution: the model is constantly being updated! You may see jumps in performance

This is a fine-tuned version of the [google/byt5-small](https://huggingface.co/google/byt5-small) for the task of generating IPA transcriptions from regional bengali text. 
This was done on the dataset of the competition [“ভাষামূল: মুখের ভাষার খোঁজে“](https://www.kaggle.com/competitions/regipa/overview) by Bengali.AI.

Best scores achieved in the leaderboards:
- **Public score**: 0.01995
- **Private score**: 0.02072

Supported district tokens:
- Kishoreganj
- Narail
- Narsingdi
- Chittagong
- Rangpur
- Tangail


## Loading & using the model
```python
# Load model directly
from transformers import AutoTokenizer, AutoModelForSeq2SeqLM

tokenizer = AutoTokenizer.from_pretrained("smji/ben2ipa-byt5small")
model = AutoModelForSeq2SeqLM.from_pretrained("smji/ben2ipa-byt5small")

"""
  The format of the input text MUST BE: <district> <bengali_text>
"""
text = "<district> bengali_text_here"
text_ids = tokenizer(text, return_tensors='pt').input_ids
model(text_ids)
```


## Using the pipeline
```python
# Use a pipeline as a high-level helper
from transformers import pipeline

device = "cuda" if torch.cuda.is_available() else "cpu"

pipe = pipeline("text2text-generation", model="smji/ben2ipa-byt5small", device=device)


"""
  Texts must be in the format of: <district> <contents>
"""
outputs = pipe(texts, max_length=1024, batch_size=batch_size)
```
