Summary

The "faster-whisper-large-v3-ca-3catparla" is an acoustic model based on a faster-whisper version of projecte-aina/whisper-large-v3-ca-3catparla suitable for Automatic Speech Recognition in Catalan.

Model Description

The "faster-whisper-large-v3-ca-3catparla" is the result of converting the projecte-aina/whisper-large-v3-ca-3catparla into a lighter model using a python module called faster-whisper.

The specific dataset used to create the projecte-aina/whisper-large-v3-ca-3catparla model is called "3CatParla".

Intended Uses and Limitations

This model can used for Automatic Speech Recognition (ASR) in Catalan. The model is intended to transcribe audio files in Catalan to plain text without punctuation.

How to Get Started with the Model

To see an updated and functional version of this code, please see our our Notebook.

Installation

In order to use this model, you may install faster-whisper

Create a virtual environment:

python -m venv /path/to/venv

Activate the environment:

source /path/to/venv/bin/activate

Install the modules:

pip install faster-whisper

For Inference

In order to transcribe audio in Catalan using this model, you can follow this example:

from faster_whisper import WhisperModel

model_size = "projecte-aina/faster-whisper-large-v3-ca-3catparla"

# Run on GPU with FP16
model = WhisperModel(model_size, device="cuda", compute_type="float16")

# or run on GPU with INT8
#model = WhisperModel(model_size, device="cuda", compute_type="int8_float16")
# or run on CPU with INT8
# model = WhisperModel(model_size, device="cpu", compute_type="int8")

segments, info = model.transcribe("audio_in_catalan.mp3", beam_size=5, task="transcribe",language="ca")

print("Detected language '%s' with probability %f" % (info.language, info.language_probability))

for segment in segments:
    print("[%.2fs -> %.2fs] %s" % (segment.start, segment.end, segment.text))

Conversion Details

Conversion procedure

This model is not a direct result of training. It is a conversion of a Whisper model using faster-whisper. The procedure to create the model is as follows:

ct2-transformers-converter --model projecte-aina/whisper-large-v3-ca-3catparla 
   --output_dir faster-whisper-large-v3-ca-3catparla 
   --copy_files preprocessor_config.json 
   --quantization float16
