“How artificial intelligence helps us understand dogs better.”
SitzPlatzFuß Magazine · Issue 64 · Feature by Lea Prexl







Built for the moments that keep you up at night
From time alone at home to unusual behavior and stress signals, Voicari helps you understand what's going on before it turns into guesswork, worry, or missed signals.

One wearable. One app.
A clearer picture of your dog
Voicari combines wearable hardware, intelligent signal analysis, and an easy-to-use app experience to help you understand what your dog may be feeling and how they are doing over time.
No setup friction. Fits like a standard collar
Buckle it on and go. Voicari starts learning your dog from the very first walk.

Every movement, bark, and vital sign is read in real time
Continuous monitoring turns raw signals into sleep, stress and activity records.

You see what your dog is feeling, and why
Emotions are mapped clearly, from curious and happy to sad and fearful.

What early owners value most
Real reassurance comes from understanding what's happening when you're not sure what your dog is trying to tell you.
Separation anxietyBruno would bark the moment I closed the door, and I never knew if it took him seconds or hours to calm down. Voicari showed me that his barking was actually anxious barking, not just boredom, like I had long assumed. With targeted training against the separation anxiety, I could then really see how his stress levels went down over the weeks. After two months, he barely barks anymore when I leave the house. For the first time, I had proof that the training actually works, not just my gut feeling.
Bruno
Training success, finally measurableAfter three months of expensive one-on-one training, I honestly didn't know if we were making any progress at all, or if I was just burning through money. With Voicari, I could see in black and white that Luna's frustration during leash training was actually decreasing week by week. That gave me real confidence for the first time that the exercises were working. Without the data, I probably would have given up. Through PetGPT, I then got matching exercises for everyday life, tailored exactly to her situation.
Luna
Rescue dog from abroadWhen we adopted Milo from Romania, he would constantly pace back and forth restlessly in certain situations and bark a lot while doing it, and we never knew exactly why. Voicari showed us that this restlessness always repeated in the same moments, a pattern that had been completely hidden from us before. With PetGPT, we then worked specifically on exactly those situations. Today he moves around much less in these moments and barks noticeably less too. I often felt like I wasn't doing right by him, and that has gotten a lot better now.
Milo
Dog walker & daycareI always felt guilty when Faula was with the dog walker, simply because I didn't know how she was really doing. Through the app, I could see that she was out and about a lot and played extensively with others, and her barking during that was clearly 'happy,' not stressed or negative barking. That gave me a peace of mind I hadn't had before. I trust the situation a lot more now, because I can actually understand what's happening.
Faula
Dog encountersAt the dog park, it almost looked like a fight between our Rocky and another dog, and I was genuinely startled for a moment. Voicari showed me afterward that it was actually still well within a safe range and both dogs were only 'playing,' even though it felt different to me in the moment. Through PetGPT, I then got tips on what to watch for next time. That gives me a lot more confidence now when it comes to encounters with other dogs. Next time, I'll try out the recording feature with the smartphone camera.
