EVP Analyser - Ghost Voice AI

🔬 EVP ANALYZER - Paranormal Audio Analysis by Artificial Intelligence

Turn your smartphone into a professional audio analysis lab. EVP Analyzer uses cutting-edge artificial intelligence technologies to examine your recordings and detect Electronic Voice Phenomena (EVP).

━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━

🎯 WHAT IS AN EVP?

Electronic Voice Phenomena (EVP) are unexplained sounds or voices captured on audio recordings. For decades, paranormal researchers and investigators have analyzed these phenomena. EVP Analyser brings a scientific and objective approach to this research.

━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━

🧠 DUAL ARTIFICIAL INTELLIGENCE

Our application combines two complementary AI engines:

TensorFlow Lite (YAMNet): A neural network trained on millions of sounds. It classifies each audio segment and accurately detects the presence of human voices.

Whisper (OpenAI): A speech recognition model capable of automatically identifying the spoken language from among 99 languages. It analyzes the linguistic characteristics of the detected segments.

━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━

📊 ADVANCED FREQUENCY ANALYSIS

Beyond AI detection, the application performs a complete acoustic analysis:

Fundamental Frequency (F0): Measures the pitch of the detected voice
Formants (F1, F2, F3): Identifies the characteristic resonances of human speech
HNR Ratio: Evaluates the harmonic clarity of the signal
Probabilistic Voice Classification: Determines the voice type (male, female, child) Probability percentages based on a multi-window Gaussian model
Anomaly detection: Identifies atypical vocal characteristics that may indicate a potential vocal disturbance (VSD)
These parameters allow for greater accuracy in differentiating a normal human voice from an unusual acoustic phenomenon.

⚠️ SCIENTIFIC APPROACH

EVP Analyser is an exploration and documentation tool. The results are indicative and should be interpreted with discernment. The app helps you sort, classify, and document your recordings objectively, but it does not constitute scientific proof of paranormal phenomena.
