Abstract
A Karaoke apparatus responds to a request message for performing an entry song. The Karaoke apparatus has a music data storage for storing music data representative of a plurality of entry songs, and a reference data storage for storing reference data representative of a multiple of key items which specify the entry songs. A microphone is provided for collecting an oral request message and for converting the same into a corresponding voice signal. The voice signal is analyzed to extract therefrom key information which suggests a desired entry song. The reference data storage is searched to detect coincidence between the key information and at least one of the key items to thereby identify the desired entry song. The Karaoke apparatus retrieves music data of the desired entry song from the music data storage to perform the desired entry song according to the retrieved music data.
