# Regional bengali text to IPA transcription - umt5-base
This is a fine-tuned version of the [google/umt5-base](https://huggingface.co/google/umt5-base) 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.
Scores achieved till now (test scores):
- **Word error rate (wer)**: 0.02390405721962450
- **Char error rate (cer)**: 0.01011514943093060
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("teamapocalypseml/ben2ipa-umt5base")
model = AutoModelForSeq2SeqLM.from_pretrained("teamapocalypseml/ben2ipa-umt5base")
"""
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="teamapocalypseml/ben2ipa-umt5base", device=device)
"""
`texts` must be in the format of: <district> <contents>
"""
outputs = pipe(texts, max_length=512, batch_size=batch_size)
```
