Abstract

Use sound recording and analysis software to record voices of your family members. Can you figure out ways to identify each family member by just looking at the analyzed sound patterns from their voice (e.g., spectral frequency analysis)? Develop a hypothesis about what types of sound analysis will identify an individual. Have a helper record additional test files of your family members, without telling you which file belongs to whom. Unplug your computer speakers and see if you can identify the voices by analyzed sound patterns alone. Then plug your speakers back in and see if you were correct!
