Accent Classification Brazillian Portuguese using CNN models

This repository showcases a classification task for Brazilian Portuguese using two model configurations: a 1D Convolutional Neural Network (CNN) combined with Long Short-Term Memory (LSTM), and a standalone 2D CNN. The CNN1D + LSTM model, based on Tostes' work, utilizes a range of frequency values from a spectrogram as input. Meanwhile, the CNN2D model processes images sized at 227x227 pixels.
