EVP Speech Recognition + Unique ‘Persistent’ SLS-like body & face detection. Simple. Clear. Unaltered. A universal straightforward unbiased entity detection and communication platform. Nothing random, nothing pre-programmed. Just raw unfiltered AI interpretation. Stick figures and eyes are drawn over people detected on camera. Words heard on the mic appear written below. Unique features: • Unlike other SLS alternatives, figures persist on-screen for several seconds, so quick appearances remain visible. • Faces are detected as well, not just body positions. • Anything you say is printed as text on-screen, including any EVPs that may be heard answering you. Coded entirely by Two Faces Paranormal, a wife and husband ghost hunting duo, based on what we wanted most for our favorite investigation techniques. Absolutely no part of this code is designed to deceive, display false figures, or unheard text. All displayed output is directly from Apple Speech Recognition or other open publicly-accessible software libraries, entirely unaltered. As AI algorithms can hallucinate, we make no claims that unexpected outputs are inherently paranormal. An open-source web version is available for integrity validation on Github. Pareidolia and confirmation bias are removed from the equation, leaving only equitable unbiased machine learning to detect what the human eye does not see or hear, with cold calculated unequivocal scientific unambiguity. 3 methods for detecting and visualizing spirit activity: • SLS-like body-tracking • Face detection • EVP-interpreting speech recognition text on-screen.
