Personality Prediction using Voice Detection is an intelligent system that analyzes a person’s speech to identify personality traits using Artificial Intelligence and Machine Learning techniques. Human voice carries valuable information such as pitch, tone, speech rate, energy, and emotional patterns, which are closely related to psychological behavior. This system captures voice samples and extracts acoustic features like MFCC, pitch, and spectral features. These features are then processed using machine learning algorithms to predict personality traits based on standard models such as the Big Five Personality Traits. The proposed approach reduces dependency on traditional questionnaires and interviews, offering a faster, objective, and automated personality assessment method. This system can be effectively used in areas such as recruitment, psychological analysis, human–computer interaction, and career guidance.
