Get Involved


We are constantly working to improve and expand our research and the ChatterBaby app.

Get involved with our research- download the ChatterBaby app today!


The ChatterBaby™ algorithm is collecting baby cries and developmental history to assess whether acoustic abnormalities heard in an infant's cry pattern may be a risk factor for a future developmental disorder such as autism spectrum disorder.

If you are a parent, please contribute to our research by filling out a survey!


Baby audio files will be stored in UCLA data servers for future research regarding baby voice correlation with developmental infant history.* Using ChatterBaby™ will allow us to build our library of audio files to help us further our research.

For more information, please refer to the Consent Form that you acknowledged and accepted when launching the app.


* We remove as much personal information as possible from audio files to better focus on the audio of the baby and our algorithms analyze the cries, not humans! See our FAQ page for more information.
