Speech recognition
Many speech recognizers fail recognizing speech from children. One of the reasons is shown in the following figure. It illustrates the first and second formant for different English vowels. The formants are plotted for American English (top left: children of age 8-10, buttom left: adults) and British English (top right: children of age 4-14). Buttom rights shows German children learning English (beginners, age 10-14).
