Contextual Interpretation
How it works: hello&meow extracts acoustic features from your recording — pitch, duration, amplitude modulation, onset patterns — then uses AI to identify the vocalization type across five behavioral categories established in feline ethology research (Schötz 2006, Nicastro 2004, McComb 2009, Bradshaw 2013). Results are for informational purposes only — consult a vet for health concerns.
