Embodiment Construction

[0015] FIG. 1 is a block diagram showing the electronic structure of a karaoke scoring device designed according to one embodiment of the present invention.

[0016] In FIG. 1, the standard speech sound is contained in music information reproduced from a storage medium such as a laser disc for karaoke, and the microphone speech sound is picked up by a microphone 2. As shown in FIG. Both speech sounds are sent to an interval extracting section 4 and a sound volume extracting section 5 through a preprocessing section 3 . Thus, the interval extraction section 4 performs interval extraction processing on the voice data representing the above-mentioned two voice sounds. At the same time, the volume extraction section 5 performs volume extraction processing on the voice data. The result of the processing is provided to the scoring section 6 . The scoring section 6 performs scoring processing on the "microphone" speech data representing the microphone speech sound based on the "sta...

Abstract

The equipment is used for scoring singing skills of singer, and can compare the microphone voice of singer obtained by microphone with the representative voice regenerated by LD, CD and similar kala OK, the comparison is performed on interval and volume. According to comparative results, the corresponding degrees of microphone voice and representative voice are detected, thereby calculating and displaying cores, the scores are increased and decreased after a length of time, and do not exceed a range. Different scoring standards are applied on front half section and rear half section of songs, so as to give a tolerant (or strict) score for one section, random numbers are introduced to provide dispersivity of scores.

Description

technical field [0001] The present invention relates to a karaoke scoring apparatus for evaluating the singing skills of a singer who sings to a music tune reproduced by a karaoke machine. Background technique [0002] Generally, karaoke machines are used to provide various functions and / or facilities to inject enthusiasm and liven up a karaoke party. As one of these facilities, a karaoke scoring device is used to rate a singer's singing skill in a hundred-point system, for example. In a karaoke scoring device, the singer's "microphone" voice picked up by a microphone is compared to a "standard" voice extracted from a storage medium (eg, a karaoke source). As a karaoke source, an optical recording medium such as a laser disc (LD) and a compact disc (CD) can be used. In this way, the microphone voice is compared with the standard voice in pitch (or musical interval) volume and its variation. The device then detects the degree of correspondence (or correlation) between the ...
