A mobile electronic device stores a standard voice command and a voice command identification standard. When an incoming call is regarded as a missed call and a voice command is detected, the mobile electronic device compares characteristics of the voice command with characteristics of the standard voice command, so as to determine if the voice command satisfies the voice command identification standard. The mobile electronic device further activates a ringing circuit to play a predetermined ring tone in response that the voice command satisfies the voice command identification standard, so as to help a user locate the mobile electronic device even if the mobile electronic device is in a silent mode.
