Supra-voice sound-responsive toy

Abstract

A toy responds to sounds having a frequency above the frequencies of normal speech. The toy may also respond to other sounds, such as sounds having frequencies corresponding to the frequencies of normal speech. In such an embodiment, the toy may be responsive to sounds in different frequency ranges, and may have different reactions depending on the frequencies of the sounds detected. Further, the responsive frequency ranges may be separated by a third range of rejected frequencies. Sounds in the third range may not activate any toy functions.
