AutoCon, an AI-powered Confidence Analysis Tool, evaluates facial expressions, vocal tone, and speech sentiment giving users personalized insights and actionable tips for impactful communication.
In a world where communication defines success—be it job interviews, public speaking, online education, or leadership—people often struggle with confidence, clarity, and emotional impact. Traditional soft-skill training methods are subjective, non-scalable, and lack real-time personalized feedback. There's a growing need for a data-driven, AI-powered solution that quantifies and improves communication confidence.
AutoCon is an intelligent confidence analysis system that utilizes advanced AI to evaluate and enhance a user's communication skills. It provides deep insights into facial expressions, vocal features, and emotional tone, and delivers real-time, personalized feedback with recommendations powered by large language models.
AutoCon bridges computer vision, NLP, and audio signal processing to offer a holistic view of a user’s communication impact—all while ensuring scalability, performance, and usability.
Facial Emotion Detection
Uses MTCNN for accurate face detection in video streams.
Extracts cropped faces frame-by-frame.
A pre-trained CNN model built on top of the FER-2013 dataset detects micro-expressions across 7 emotions (Happy, Sad, Angry, etc.).
Outputs emotion timelines to gauge emotional variance and presence.
Speech Sentiment & Emotion Analysis
Extracts audio using FFmpeg.
Processes audio with Deepgram API to generate real-time transcripts.
Applies VADER sentiment analysis to the transcript for textual sentiment classification (positive, neutral, negative).
Correlates audio tone with spoken content to detect emotional dissonance.
Audio Feature Analysis with Librosa
Extracts pitch, energy, speech rate, and spectral features.
Analyzes clarity, fluency, and vocal modulation.
Detects filler words, stammering, or low-energy tones to give vocal feedback.
Posture & Gesture Recognition
Integration-ready with MoveNet Thunder to assess body language.
Posture symmetry and hand gesture energy contribute to the engagement score.
Insight & Recommendation Engine
All scores are fed into a Gemini-powered LLM that generates:
Personalized feedback.
Growth suggestions.
Weekly improvement plans based on emotion trends and vocal clarity.
Scalable Backend & User Tracking
Built on MongoDB Atlas to handle analysis results and user metadata at scale.
Tracks user progress, computes monthly averages, and offers performance dashboards.
