Abstract
The invention provides an indication for a karaoke singer of that music in the karaoke music library which would be best suited to the singer's own vocal characteristics. For the purpose of providing this indication, the singer's voice signals are first of all sampled at suitable intervals and the sample waveforms converted into specimens made up of digital values. A body of data relating to vocal characteristics is at the same time stored in the device, each item of said data being assigned its own code. When the above specimens are input, they are compared with the stored data by an evaluation means which then identifies the items of data that resemble each other most closely. The codes which are incorporated into the data items so identified are then treated as retrieval items and any library data with a matching code for each of a plurality of pieces of music is duly retrieved and the music with the matching code is extracted.
