A baby can try to communicate with us and at the best of times that can be difficult. For a parent who is hearing impaired this can also be difficult as they may need to rely on amplifiers to better communicate the sounds to them. Chatter Baby, a new app, tries to solve this issue – with an app that will notify of the sound and what the baby may be asking for too! See the video:

From the information on Chatter Baby:

The ChatterBaby app not only lets deaf parents know when their baby is crying, it also can tell them why they’re crying. “The app analyzes the different types of frequencies that are in the cry and the different patterns of sound and silence,” said Ariana Anderson, PhD, assistant professor in residence at the UCLA Semel Institute who spearheaded the development of the app. “For example, if a cry has a long period of silence, it’s more likely that the baby is fussy.

If there are constant, high-volume frequencies, it’s more likely the baby is in pain.” Anderson is a mother of four who got the idea for the app after noticing the variations of cries in her own children. She then collected a database of more than 2,000 infant cries and used machine learning to build the algorithms used in the app.

“Current technology will alert parents when there is a sound coming from a child, but it doesn’t distinguish what type of sound it is,” said Anderson. “This categorizes the cries to tell parents whether the baby is hungry or fussy or, with more than 90 percent accuracy, can determine if a baby is crying because it’s in pain”


This is a very interesting technology use and there is a development from Microsoft at the moment that is being tested called ‘hearing AI’ that will monitor sounds in the environment. Then it will alert you if there is a loud noise. It will also indicate the loudness of that noise through the use of colours.

Additionally, it will translate voice into text. I have not yet had a chance to try this app and it is unclear when it will be published. Microsoft did release a previous app called Seeing AI which is a great assistant app for visually impaired people. We will be following up with another post soon!

If you do try the app we would love to know your thoughts about it, drop us a comment!
