Using GANs to predict faces from voices

About this repo

This repo is based on wav2pix, However it was optimized for the following:

• Python 3.x (previously 2.7 only)
• CUDA 10 (previously CUDA 9 or below)
• Google Colab
• All the packages from the original wav2pix have been changed, replaced or updated (including PyTorch) check requirements.txt for more info

this project was used as baseline.

Introduction

Speech is a rich biometric signal that contains information about the identity, gender and emotional state of the speaker. In this work, we explore its potential to generate face images of a speaker by conditioning a Generative Adversarial Network (GAN) with raw speech input. We propose a deep neural network that is trained from scratch in an end-to-end fashion, generating a face directly from the raw speech waveform without any additional identity information (e.g reference image or one-hot encoding). Our model is trained in a self-supervised fashion by exploiting the audio and visual signals naturally aligned in videos. With the purpose of training from video data, we present a novel dataset collected for this work, with high-quality videos of ten youtubers with notable expressiveness in both the speech and visual signals.
