The Solution

Voicari decodes emotions through AI-powered analysis of barking and vital signs. It bridges the emotional gap, strengthens trust, and prevents misunderstandings — all in real time.

Voicari is not a medical or veterinary device. For health or behavioral concerns, always consult a qualified veterinarian.

Giving Dogs a Voice –
Backed by Science & Empathy

At Voicari, we're not just building another pet app — we're creating a scientifically validated AI platform that listens and understands.

With over 20,000 bark samples, advanced neural networks, and a smart wearable collar, we're changing how humans connect with dogs.

"Voicari takes an exciting approach, using thoughtful technology to interpret the emotional states of dogs. Too often, pets are anthropomorphized and their true needs are overlooked. Voicari can help foster a deeper understanding between humans and animals, ultimately improving animal welfare. This is something we find highly valuable and fully support with First Lvl Pets."
