About CryBuddy

CryBuddy uses advanced sound analysis and artificial intelligence to help parents better understand their baby's cries. The app is designed to provide insight and support, but it is not a medical device and does not replace professional healthcare advice.

Always consult a qualified healthcare professional if you are concerned about your baby's health or wellbeing.

Our Methodology

CryBuddy's analysis is based on two key layers:

Acoustic Screening

We use signal processing to check for features that match baby cries, such as pitch, rhythm, and energy patterns.

This helps filter out adult speech, background noise, and short bursts of sound that are not real crying.

AI Pattern Recognition

Once a sound passes screening, it is analysed by an AI model trained on research-informed acoustic features found in infant cries.

The system looks at factors such as:

  • Pitch contour – higher, sharper cries may be associated with hunger or discomfort.
  • Cry duration – longer, rhythmic cries can suggest tiredness.
  • Pause patterns – irregular pauses can indicate colic or distress.
  • Harmonic-to-noise ratio – differences in vocal quality that may reflect varying states of need.

By comparing these features, CryBuddy highlights patterns commonly linked to hunger, tiredness, or general discomfort.

These insights are provided for informational and educational purposes only, not as medical advice.
