摘要方言变异是语言学和其他社会科学的一个重要研究课题。然而,传统上它一直使用代理(transmittance)而不是直接的声学记录进行研究。我们引入了新的统计技术来分析地理定位的语音记录,并不断探索感兴趣的区域的发音的空间变化,而不是传统的isoglosses,它提供了一个离散的分区的区域。这种类型的数据需要对平均值和协方差的变化进行显式建模。欧氏度量是不合适的,因此我们引入了d-协方差的概念,它允许在空间和单个位置进行一致的估计。然后,我们提出了空间平滑这些对象,占可能的非凸几何形状的域的兴趣。我们应用所提出的方法,从口语的一部分,存放在大英图书馆,伦敦的英国国家语料库的数据,我们制作的地图,在英国的方言变化。此外,这些方法允许在感兴趣的领域进行声学重建,使研究人员能够听取统计分析。本文的补充材料可在网上查阅。
Abstract Dialect variation is of considerable interest in linguistics and other social sciences. However, traditionally it has been studied using proxies (transcriptions) rather than acoustic recordings directly. We introduce novel statistical techniques to analyze geolocalized speech recordings and to explore the spatial variation of pronunciations continuously over the region of interest, as opposed to traditional isoglosses, which provide a discrete partition of the region. Data of this type require an explicit modeling of the variation in the mean and the covariance. Usual Euclidean metrics are not appropriate, and we therefore introduce the concept of d-covariance, which allows consistent estimation both in space and at individual locations. We then propose spatial smoothing for these objects which accounts for the possibly nonconvex geometry of the domain of interest. We apply the proposed method to data from the spoken part of the British National Corpus, deposited at the British Library, London, and we produce maps of the dialect variation over Great Britain. In addition, the methods allow for acoustic reconstruction across the domain of interest, allowing researchers to listen to the statistical analysis. Supplementary materials for this article are available online.
