This device translates babies' cries into words

Zoundream is advertised as the "world's first translator of newborn cries." It makes use of all the latest buzzwords: "Internet of things," "Big data," and "Artificial intelligence" to decipher what your squawking infant is trying to tell you: "I'm hungry," "I need to burp," "I'm uncomfortable," "I'm so sleepy," or "I've stomach pain."

How does it works

Parents just need to keep Baby Translator nearby their baby

Baby Translator automatically detects baby cries, filtering any other sound

Whenever a cry is recognised, Baby Translator analyzes it in a few seconds

The cry is translated, and the feedback is shown on device screen

I think they are serious.
