Abstract: A technique of enabling a singer to auditorily recognize how to change the way of singing is provided. The CPU (11) of a karaoke device (1) associates model voice data stored in a model voice data storage area (14c) with inputted learner voice data in a time axis direction. Then the CPU (11) shifts the pitch of the learner voice data so that it may coincide with the corresponding pitch of the model voice data according to the result of the association, compresses or extends the section (mora) of the learner voice data in the time axis direction so that the section length of the learner voice data coincides with the corresponding section length of the model voice data, and outputs the resultant learner voice data to a voice processing section (18). The voice processing section (18) converts the learner voice data supplied from the CPU (11) into an analog signal and generates the sound from a loudspeaker (19).

Abstract: An RFID tag-reading notification apparatus which is capable of alerting a user by notifying the user that information has been or is going to be read from an RFID tag by a third party, without tailoring the RFID tag. A receiver section receives one of radio waves generated by an RFID reader and a signal transmitted from at least one RFID tag having received the radio waves. When the receiver section receives at least one of the radio waves and the signal, the notification apparatus outputs a notification signal indicative of reading of information from the RFID tag by the RFID reader.

Abstract: An RFID tag-containing apparatus which is capable of alerting a user to leakage of information stored in RFID tags without tailoring the RFID tags. At least one container section is capable of containing at least one article. A receiver section receives information transmitted from an RFID tag attached to the article contained in the container section. When the receiver section receives the information from the RFID tag, a notification signal is output for notifying a user that the information stored in the RFID tag has been be read.
