对京剧唱腔教学有辅助作用的音乐信息提取技术鉴别（英文）

Identification of potential Music Information Retrieval technologies for computer-aided jingju singing training

音乐信息提取(Music Information Retrieval)技术在辅助西方古典声乐训练中已经被证明有效。京剧演唱在多个感知维度上有别于西方古典声乐,并采用口传心授的方式进行教学。首先介绍京剧演唱专业课堂中的教学方法,并展示在教学过程中引入音乐信息提取技术的潜在好处。为了揭示能服务于京剧演唱教学的潜在音乐信息提取技术,首先发问:京剧演唱老师和学生对京剧音乐的五个维度—音调、节奏、响度、音质和发音的重要性是如何度量的?通过向这五个维度对课堂练习、老师的言语反馈进行归类和对学生的调查来回答这个问题。然后,借助音乐信号分析来详细观察课堂练习和老师的言语反馈录音,以此揭示教学过程中的细节元素。最终,基于以上分析,提出了潜在对京剧演唱教学有辅助作用的音乐信息提取技术。

Music Information Retrieval（ MIR） technologies have been proven useful in assisting western classical singing training.Jingju（ also known as Beijing or Peking opera） singing is different from western singing in terms of most of the perceptual dimensions,and the trainees are taught by using mouth/heart method. In this paper,we first present the training method used in the professional jingju training classroom scenario and show the potential benefits of introducing the MIR technologies into the training process. The main part of this paper dedicates to identify the potential MIR technologies for jingju singing training. To this intent,we answer the question∶ how the jingju singing tutors and trainees value the importance of each jingju musical dimension—intonation,rhythm,loudness,tone quality and pronunciation？ This is done by（ i） classifying the classroom singing practices,tutor＇s verbal feedbacks into these 5 dimensions,（ ii） surveying the trainees. Then,with the help of the music signal analysis,a finer inspection on the classroom practice recording examples reveals the detailed elements in the training process. Finally,based on the above analysis,several potential MIR technologies are identified and would be useful for the jingju singing training.
