AI Technical Summary

Technical Problem

Existing karaoke devices struggle to accurately identify and score karaoke singing techniques such as note-end hammer-on singing, which involves unique pitch transitions not captured by existing methods.

Method used

A karaoke device that analyzes singing pitches to detect specific pitch differences and transitions, identifying a horizontal section followed by a rising section with predetermined criteria to determine if hammer-on singing is performed at the end of a note, using a singing pitch detection unit and a singing technique determination unit.

Benefits of technology

Enables accurate detection and scoring of hammer-on singing at the end of a note, preventing false scoring and providing feedback to users, thus enhancing the karaoke experience by reflecting the singer's technique accurately.

Abstract

To provide a karaoke device capable of determining whether note end hammering-on singing is included in karaoke singing.SOLUTION: A karaoke device includes a singing technique determination part for determining that note end hammering-on singing is performed in one note when a horizontal section and a rise section exist in a singing pitch detected during a period from sounding start timing to sounding end timing of one note included in reference data of karaoke music, the singing pitch at the time when the rise section terminates is included between a reference pitch of one note and the singing pitch that is lower than the reference pitch by a first prescribed value and the singing pitch at the time when the rise section terminates is equal to or more than a second prescribed value with respect to the singing pitch of the horizontal section.SELECTED DRAWING: Figure 3
