Voice gender classifier

• This repo contains the inference code to use pretrained human voice gender classifier.
• You could also try 🤗Huggingface online demo.

Installation

First, clone the original github repository

git clone https://github.com/JaesungHuh/voice-gender-classifier.git

and install the packages via pip.

cd voice-gender-classifier
pip install -r requirements.txt

Usage

import torch

from model import ECAPA_gender

# You could directly download the model from the huggingface model hub
model = ECAPA_gender.from_pretrained("JaesungHuh/voice-gender-classifier")
model.eval()

# If you are using gpu .... 
device = torch.device("cuda" if torch.cuda.is_available() else "cpu")
model.to(device)

# Load the audio file and use predict function to directly get the output
example_file = "data/00001.wav"
with torch.no_grad():
    output = model.predict(example_file, device=device)
    print("Gender : ", output)

Training details

State-of-the-art speaker verification model already produces good representation of the speaker's gender.

I used the pretrained ECAPA-TDNN from TaoRuijie's repository, added one linear layer to make two-class classifier, and finetuned the model with the VoxCeleb2 dev set.

The model achieved 98.7% accuracy on the VoxCeleb1 identification test split.

Caveat

I would like to note the training dataset I've used for this model (VoxCeleb) may not represent the global human population. Please be careful of unintended biases when using this model.
