## What is ChatterBaby?

What is ChatterBaby?
ChatterBaby compares your baby’s sounds to our database of roughly 1,500 sounds, to determine whether and why your infant cries. It uses math(emagics). Before you use it, you must apologize to every math teacher you’ve ever told, “Why do I need to learn this junk?”

How accurate is ChatterBaby?
ChatterBaby correctly identifies roughly 85% of pain cries, and is roughly 90% accurate for catching any baby cries. Fussy/whiny cries are the cries most often mistaken for non-crying.

How can I make ChatterBaby work better?
The less background noise is present, the better the algorithm will work. If you feed it a soundclip of you singing to your crying baby, it will not work. If you feed ChatterBaby a soundclip of your dog barking, it will not work.

What kinds of cries does ChatterBaby predict?
The algorithm assumes the baby is crying for only three reasons: hungry, fussy, and pain. If your baby is crying because he really, really, wants to taste some Legos and you just won’t let him (true story), it will not work. Sad fact: separation anxiety cries are predicted as “pain” by our algorithm.

Can I trust the ChatterBaby algorithm?
Your brain and your own intuition are far more powerful than the fanciest equations. If the ChatterBaby algorithm and your own common sense disagree, always trust your brain.

What happens to my data?
We store it for science on a server that is HIPAA-compliant, removing as much information as possible that links your data to you individually. We are interested in discovering whether abnormal vocalization patterns in infants can predict neurodevelopmental delays such as autism. Odds are, a human being will never actually hear your baby’s audio sample; a computer script will run some math on it and throw the answers in a big spreadsheet to do even more math. For more information, see the Consent Form you agreed to when launching the app: link to consent.

Is there a warranty?
Nope. Nein. Zero. Zilch. Nada.

Is this a medical device?
No. See also “Can I trust the ChatterBaby algorithm?“ above.

What about remote monitoring?
TBD.

### 5/5 — Bella

*2026-07-30, version 3.1*

Llore

### 1/5 — Pointless

*2026-07-21, version 3.1*

What a stupid app, it basically tells me to self diagnose why my baby is crying. The recording time barely gives you enough time to record my baby crying and then says were we right, then tells me to diagnose it. What a pointless false advertising app.

### 1/5 — Not accurate

*2026-04-19, version 3.0*

Always says not fussy when she is clearly crying and hungry

### 3/5 — Wishful thinking

*2026-03-28, version 3.0*

I like the app but I wish we could type in what the cries mean if they’re not on the list instead of hitting unknown, it’s mostly accurate but only shows pain, fussy, hungry

### 1/5 — Not helpful

*2026-03-08, version 3.0*

Literally just gives an answer of “all of the above” with saying around 30% possible for all 3 answers.

### 4/5 — Try

*2026-01-28, version 3.0*

Bob

### 4/5 — The timeframe is too short

*2025-12-13, version 3.0*

I can never really capture the crying but promising research!

### 1/5 — Pode estar vivo com 22% ou encomende o caixão com 92%

*2025-11-13, version 3.0*

Random probability that points to your mood

### 1/5 — Yok

*2025-11-11, version 3.0*

Yani yabancı olması çok saçma olmuş biz Türkler olarak nasıl kullancaz acaba

### 1/5 — “Not crying”

*2025-08-11, version 3.0*

More often than not says “not crying” despite baby wailing. Or says “fussy”. Not helpful as I only use it when I don’t know what’s wrong and can’t calm baby down.
