Whisper-Large v3 for Spanish Dialect Classification
Model Description
This model includes the implementation of Spanish dialect classification described in Voxlect: A Speech Foundation Model Benchmark for Modeling Dialect and Regional Languages Around the Globe
Github repository: https://github.com/tiantiaf0627/voxlect
The included Spanish dialects are:
[
"Andino-Pacífico",
"Caribe and Central",
"Chileno",
"Mexican",
"Penisular",
"Rioplatense",
]
How to use this model
Download repo
git clone git@github.com:tiantiaf0627/voxlect
Install the package
conda create -n voxlect python=3.8
cd voxlect
pip install -e .
Load the model
# Load libraries
import torch
import torch.nn.functional as F
from src.model.dialect.whisper_dialect import WhisperWrapper
# Find device
device = torch.device("cuda") if torch.cuda.is_available() else "cpu"
# Load model from Huggingface
model = WhisperWrapper.from_pretrained("tiantiaf/voxlect-spanish-dialect-whisper-large-v3").to(device)
model.eval()
Prediction
# Label List
dialect_list = [
"Andino-Pacífico",
"Caribe and Central",
"Chileno",
"Mexican",
"Penisular",
"Rioplatense",
]
# Load data, here just zeros as the example
# Our training data filters output audio shorter than 3 seconds (unreliable predictions) and longer than 15 seconds (computation limitation)
# So you need to prepare your audio to a maximum of 15 seconds, 16kHz and mono channel
max_audio_length = 15 * 16000
data = torch.zeros([1, 16000]).float().to(device)[:, :max_audio_length]
logits, embeddings = model(data, return_feature=True)
# Probability and output
dialect_prob = F.softmax(logits, dim=1)
print(dialect_list[torch.argmax(dialect_prob).detach().cpu().item()])
