# Aina Project's Catalan text-to-speech model
## Model description
This model was fine-tuned from a pre-trained Spanish [stt-es-citrinet-512](https://catalog.ngc.nvidia.com/orgs/nvidia/teams/nemo/models/stt_es_citrinet_512) model using the [NeMo](https://github.com/NVIDIA/NeMo) toolkit.
## Intended uses and limitations
You can use this model for Automatic Speech Recognition (ASR) in catalan.
## How to use
### Usage
Requiered libraries:
```bash
pip install nemo_toolkit['all']
```
Clone the repository to download the model:
```bash
git clone https://huggingface.co/projecte-aina/stt-ca-citrinet-512
```
Given that `NEMO_PATH` is the path that points to the downloaded stt-ca-citrinet-512.nemo file, to do inference over a set of `.wav` files you should:
```python
# Load the model
model = nemo_asr.models.EncDecCTCModel.restore_from(NEMO_PATH)
# Create a list pointing to the audio files
paths2audio_files = ["audio_1.wav", ..., "audio_n.wav"]
# Fix the batch size to whatever number suits your purpose
batch_size = 8
# Transcribe the audio files
transcriptions = model.transcribe(paths2audio_files=paths2audio_files,
batch_size=batch_size)
# Visualize the transcriptions
print(transcriptions)
```
