Labs: 1 | 2 | 3 | 4 | 5 | 6 | 7 | 8 | 9 | 10 | 11 | 12 | 13 | 14 | 15 | 16 | 17

The main purpose of this laboratory is to use perception and acoustic analysis to study (1) normal speech production of children, (2) misarticulations by children, and (3) speech of deaf children.

Here are the resources that you will need:
