Not a translator. A wellbeing meter. It listens through your phone, reports a likely emotional state with a confidence score, and says "unclear" when the sound is ambiguous. It never turns a bark into a sentence.
This reader runs entirely in your browser. Nothing is recorded, uploaded or stored. It reports the three acoustic features the published bark research is built on, and names the pattern the sound leans toward. It is a signal reader, not the app's full model, and it is not a diagnosis.
Most products in this category claim a translation they cannot demonstrate. We would rather tell you the shape of the thing and let you decide.
Pongracz and colleagues found in 2006 that human listeners could classify dog barks by context, and that three acoustic properties carried most of that signal. The live reader above measures exactly those three and nothing else. You can watch it work.
The fundamental frequency of the bark. Low pitched barks skew toward aggressive and guarding contexts. High pitched barks skew toward fear, excitement and play.
How tonal or how noisy the sound is. Harsh, noisy, broadband barks skew aggressive. Clean tonal barks and whines skew toward fear, anxiety and appeal.
The gap between barks. Short gaps and rapid repetition skew aggressive or alarmed. Longer, irregular gaps with higher pitch skew playful.
Those three rules are real findings about populations of dogs. They are not a verdict about your dog, in your kitchen, right now. A single sound can match a pattern and still mean something else. That is exactly why the app shows a confidence score and refuses to answer when the signal is weak.
Here is the current state of machine bark classification, with links, including the parts that are inconvenient for us.
Bark Mood Decoder has not been independently validated either. We are not exempt from the standard we just applied to everyone else. Until an independent validation exists, this page will not carry an accuracy percentage, and the app will keep showing you a confidence score instead of a promise.
Written down here so you never have to find out the expensive way.
It reports what a sound resembles. Interior experience is not recoverable from audio, by us or by anyone else selling you a subscription.
A change in vocal pattern is a thing to watch and to mention to your vet. It is not a medical finding and we will never present it as one.
Television, other dogs, a dishwasher. When the signal is poor the app says unclear rather than inventing a state.
Because no independent validation exists. Every read shows a confidence score and the top two candidate states, which is what we can honestly give you.
It is new. When there is a real review from a real owner or trainer, it will appear here with their name on it, and not before.
If your dog is in distress, escalating, or hurting someone, hire a professional. This is a logging and awareness tool sitting next to that work.
The app is genuinely free. If you are a trainer, a shelter, a daycare or a vet practice and you need it shaped around your operation, that is the paid path.
Open it in your browser, name your dog, and start reading. Unlimited reads, the mood deck, the log, the confidence scores, the whole thing. No account, no card, no download, and no audio leaving your device. There is no upsell inside it.
These are Purpose Built AI monthly plans. You are buying build time and a direct line, applied to Bark Mood Decoder and to whatever else your operation needs.
Said plainly, because it matters: the professional dashboard is not a finished shipped product yet. What exists today is the working app you can open for free, plus a person in Utah who builds. A monthly plan buys that person's time and puts your operation first in the queue. If that is not what you want, use the free app and pay nothing. Cancel any month.
No, and it never will. There is no published science supporting bark to sentence translation. What it does is report a likely emotional state and arousal level, with a confidence score, from the acoustics of the sound. If a product promises you sentences, that is a marketing decision, not a research finding.
We do not publish an accuracy number, because no independent validation of this app exists. Quoting a percentage we cannot back would be the single easiest way to lose your trust, and it is also the exact conduct the Federal Trade Commission acted on in its 2025 order against Workado over unsupported AI accuracy claims. Every read shows its own confidence instead.
Nowhere. The reader on this page and the app itself both run entirely in your browser. There is no upload, no server call, no account and no recording stored anywhere but on your own device. You can verify it by opening your browser's network tab while you use either one.
No. It uses the microphone in the phone or laptop you already have. The collar products in this category cost between roughly one hundred and several hundred dollars up front and then charge a monthly fee on top. This does not.
No. It can help you notice that your dog's vocal pattern has changed, which is a reasonable thing to raise with your veterinarian. It is not a diagnostic device and nothing it shows you should delay a vet visit.
Because the free app is built for one owner and one dog. A professional plan buys the version shaped around a roster, a log you can hand to a client with your name on it, and the ability to say what gets built next. You are paying for build time and access, not for unlocking features that already exist.
