中文简介:
检测现代流行音乐中的鲜明特征是一个重要的问题,可以在多媒体娱乐等领域有重要的应用。例如,它们可以用于给出声音的视觉上连贯的表示。我们建议将歌声检测器与多媒体,多点触摸游戏集成,其中用户必须在音乐中的某些关键点执行简单任务。虽然最终目标是自动创建视觉内容以响应从图像中提取的特征,但在此我们特别关注音乐中语音片段的检测。所提出的解决方案提取声音的梅尔频率倒谱系数并使用隐马尔可夫模型来推断声音是否具有声音。与使用梅尔频率倒谱系数的其他歌唱声音检测器相比,获得的分类率高。
课程简介: Detecting distinct features in modern pop music is an important problem that can have significant applications in areas such as multimedia entertainment. They can be used, for example, to give a visually coherent representation of the sound. We propose to integrate a singing voice detector with a multimedia, multi-touch game where the user has to perform simple tasks at certain key points in the music. While the ultimate goal is to automatically create visual content in response to features extracted from the music, here we give special focus to the detection of voice segments in music songs. The solution presented extracts the Mel-Frequency Cepstral Coefficients of the sound and uses a Hidden Markov Model to infer if the sound has voice. The classification rate obtained is high when compared to other singing voice detectors that use Mel-Frequency Cepstral Coefficients.
