Abstract
Abstract Conventional karaoke devices simply show lyrics on screen. This invention displays not only lyrics but also data useful for the enhancement of the singer's presentation such as the strength of the vocals and the pitch. More precisely, vocal data, which indicates the special requisites of a specific vocal rendition such as its strength and pitch, and the current lyric position indicator, which marks the current position in the lyrics, are correlated with the music data to which they correspond and then stored in memory. The said vocal data and current lyric position data are then read out of memory and each block of vocal data is displayed on the screen of a visual display medium a little in advance of the music to which it corresponds while the current lyric position within said block of vocal data is indicated in time with the music. Moreover, the strength and basic frequency of an actual vocal rendition can be detected and compared with the stored vocal data.
