Abstract
A portable cellular phone including the ability to customize a ring signal. The device accepts a spoken voice signal entered via a microphone and converts that signal into a digital audio signal. The device then obtains musical scale information from the digital audio signal by extracting frequency components. The device uses those frequency components to generate an audio output signal based on the extracted musical scale frequency components. This output signal can then be used as the ring signal, or for other purposes. Thus, a user can input a desired musical scale using the user's voice to customize the ring signal without relying solely on keypad operations.
