Hi All,

I write some software that discriminate voices of adults children and baies.
I use a simple pitch tracker that filters the base band and looks for a zero
crossing to identify the pitch. This works fine and depending on the pitch
length it decides whther its an adult a child or a baby voice.  I'm looking
for a way to improve the algorithm by checking the formants or other voice
paramters. Can someone advice with ideas or references?

Thanks In Advance
