New Tool Diagnoses Developmental Disorders By Analyzing Infant Cries
Reporting in the Journal of Speech, Language, and Hearing Research, researchers say their tool operates in two phases.
In the first, an analyzer cuts the recording of a baby crying into 12.5-millisecond chunks and analyzes them for a variety of parameters, including acoustic volume and how frequently certain characteristics occur. During the second phase, the frames are put back together and characterized using info from the first phase as a single “wah” or as silence — the pause between the wahs. The time between those utterances is recorded, and all of this allows for things like pitch and other variables to be averaged across utterances.
Ultimately, the tool is able to evaluate 80 parameters, providing an auditory view of the child’s brain.
