Speech‑Based Pain Type Classifier
In seconds, pinpoint whether discomfort in someone’s voice is physical or emotional.

Overview
Our AI‑powered desktop tool analyses a short WAV recording of someone describing their pain or distress, then instantly tells you not only the likelihood that they’re in pain, but also whether that pain is coming from a bodily injury or an emotional experience. It works entirely offline—no sensitive audio ever leaves your computer.

Key Features

• Dual‑Mode Detection
  • Pain Probability: A 0.0–1.0 score indicating how strongly the voice conveys pain.
  • Pain Type: Classifies pain as Physical (injury, ache, burn) or Emotional (sadness, anxiety, heartbreak).
• Rapid & Easy
  • Record a 5–30 second WAV and run it through our intuitive launcher or via command‑line.
  • Results appear in under a second—no complex setup, no cloud delays.
• Privacy‑First
  • Entirely self‑contained. No internet connection required after installation.
  • All processing (denoising, feature extraction, classification) happens locally.
• Versatile Integration
  • Use our batch‑file launcher for a drag‑&‑drop GUI.
  • Integrate the CLI (pain_cli.exe)into larger workflows or tele‑health pipelines.

Who It’s For

• Clinicians & Therapists: Get an objective “second opinion” on patients’ pain levels.
• Researchers: Rapidly label large speech datasets for pain studies.
• Caregivers & Coaches: Monitor emotional well-being and physical discomfort remotely.

How It Works (Under the Hood)

1. Audio Denoising and Feature Extraction: This process cleans up background noise and computes voice‑signal statistics (energy, pitch, MFCCS).
2. Machine Learning Models:
   • A Random Forest regressor estimates pain intensity.
   • A separate classifier distinguishes physical vs. emotional cues.
3. Output:

   Pain probability: 0.78  
   Detected pain type: Emotional (Physical: 0.32, Emotional: 0.68)
   

System Requirements

• Windows 10 or later (64‑bit)
• WAV audio files (mono or stereo, speech‑only recommended)
• ~785 MB disk space for models and bundled dependencies
