Abstract: PROBLEM TO BE SOLVED: To reduce failure in detection when detecting a falsetto from singer's singing voice.SOLUTION: When generating voice information data including a harmonic tone rate, a pitch, and a lapse time as information from user's singing voice data (step S110), a control unit 10 allocates the voice information data to a voice distribution table (step S112). The control unit 10 subjects the voice information data to processing using a filter to successively calculate a calculation value (step S114). When the calculated calculation value exceeds a preliminarily determined threshold (YES; in step S116), the control unit 10 decides a position of the filter at timing when the calculated value exceeds the threshold (step S120). The control unit 10 detects voice information data included in a positively weighted region in the filter, as voice information data based on a falsetto (step S122).
Abstract translation: 要解决的问题：当从歌手的歌声中检测到falsetto时，减少检测失败。 解决方案：控制单元10当生成包括来自用户唱歌语音数据的信息的谐波音调率，音高和经过时间的语音信息数据（步骤S110）时，将语音信息数据分配给语音分配表 步骤S112）。 控制单元10使用滤波器对语音信息数据进行处理，以连续计算计算值（步骤S114）。 当计算出的计算值超过预先确定的阈值（步骤S116为“是”）时，控制部10在计算出的值超过阈值的定时，决定滤波器的位置（步骤S120）。 控制单元10检测包括在滤波器中的正加权区域中的语音信息数据作为基于falsetto的语音信息数据（步骤S122）。 版权所有（C）2013，JPO＆INPIT

Abstract: PROBLEM TO BE SOLVED: To provide a Karaoke machine with a scoring function that makes it possible to accurately decide whether a singing is good by detecting singing timing with high precision.
SOLUTION: A singing frequency is compared with a reference frequency and when the singing frequency enters a specified range from the reference frequency, singing timing of the note is decided. Cross-correlations between reference frequency waveforms of precedent and following notes and a singing frequency waveform are obtained and the position of the largest cross-correlation is decided as singing timing. Consequently, the timing of even a legato singing can accurately be detected to accurately score the singing by the timing.
