Voice Based Gender Classifier Streamlit in Python Projects

Voice Based Gender Classifier Streamlit in Python Projects
Abstract
Voice signals carry information about a speaker’s gender, which can be leveraged for applications in security, personalized services, and human-computer interaction. This project focuses on Voice-Based Gender Classification using Machine Learning and Streamlit in Python, which classifies audio recordings as male or female. The system collects voice samples, preprocesses them to reduce noise, and extracts relevant features such as pitch, formants, MFCCs (Mel Frequency Cepstral Coefficients), and energy. Machine learning models like Random Forest, Support Vector Machines (SVM), or Gradient Boosting are trained to classify the gender of speakers. Streamlit is used to develop an interactive web application that allows users to upload their voice recordings and receive real-time gender classification results. The project aims to provide an automated, accurate, and accessible voice-based gender detection system.

Existing System
Existing gender detection systems mainly rely on manual analysis or basic acoustic measurements such as average pitch. Manual approaches are time-consuming, error-prone, and cannot scale effectively. Traditional voice-based systems using only pitch or energy often fail to capture complex features that distinguish gender, particularly in overlapping pitch ranges or with noisy recordings. Moreover, many existing solutions lack interactive visualization and real-time prediction capabilities, limiting their usability in practical applications such as voice authentication, personalized systems, or call center analytics.

Proposed System

The proposed system implements a Python-based machine learning framework for voice-based gender classification, integrated with a Streamlit web interface for real-time interaction. Voice samples are collected and preprocessed for noise reduction, normalization, and feature extraction. Features such as MFCCs, pitch, formants, and energy are used to build a robust dataset for model training. Supervised machine learning models like Random Forest, Gradient Boosting, or SVM are trained to classify voice samples into male or female categories. The Streamlit interface allows users to upload audio recordings and receive real-time predictions, along with visualizations of extracted features. By combining audio analysis, machine learning, and interactive deployment, the system provides a scalable, accurate, and user-friendly solution for automated gender classification from voice signals.
