🧠 Contextual Interpretation
How it works: hello&meow uses the FGC 2.3 taxonomy (Dr. Vlad Reznikov, 2025) to classify cat vocalizations into 40 distinct types across 5 behavioral groups. The AI analyzes acoustic features extracted locally from your audio, achieving ~95% accuracy in controlled settings. Results are for informational purposes only—consult a vet for behavioral or health concerns.
