SPeech Across Dialects of English (SPADE): large-scale digital analysis of a spoken language across space and time

任何人都可以通过通用的大规模搜索算法（如Google n-gram查看器）在几秒钟内获得文本搜索的数据可视化。相比之下，语音研究现在才进入它自己的“大数据”革命。从历史上看，语言学研究倾向于对来自一种或几种语言或方言的语音的几个方面进行细粒度的分析。目前的言语研究规模已经塑造了我们对口语的理解和我们提出的各种问题。今天，大量的数字化转录语音集合可以从许多不同的语言中获得，收集用于许多不同的目的：从口述历史到用于训练语音识别系统的大型数据集，再到法律的和政治互动。存在复杂的语音处理工具来分析这些数据，但需要大量的技术技能。鉴于数据和工具的融合，语言学家有了新的机会来回答有关口语的本质和发展的基本问题。我们的项目旨在建立关键工具，使大规模的语音研究成为强大的和普遍的大规模文本挖掘。它是基于苏格兰、加拿大和美国三个团队的合作。我们将共同利用计算科学的方法，并将其与语音科学，语言学和数字人文学的工具和方法相结合，以发现大西洋两岸的英语声音在空间和时间上的差异。我们将开发一个创新的和用户友好的软件，利用现有的语音数据和语音处理工具的可用性，以促进跨多个数据集的大规模集成语音语料库分析在一起。这种方法的好处是巨大的：语言学家将能够扩大现有研究问题的答案，从一种语言到多种语言，并在社会，地区和文化背景下提出关于口语的新的和不同的问题。计算语言学，语音技术，法医和临床语言学研究人员，谁从事口语的变化，也将直接受益于我们的软件。该项目还将为那些已经在更广泛的人文和社会科学中使用数字奖学金的口语收藏的人开辟巨大的潜力，例如文学学者，社会学家，人类学家，历史学家，政治学家。对语音和文本进行道德上非侵入性检查的可能性将使分析师能够发现比仅通过文本分析所能发现的更多的东西。我们的项目将使用旧世界现有的43个公共和私人口语数据集，开发并将我们的新软件应用于全球语言英语（不列颠群岛）和新世界（北美）英语，有效时间跨度超过100年，横跨整个世纪。我们对英语口语的了解，大部分来自于对一两种方言中言语的一些特定方面的有影响力的研究。这些大量的文献已经建立了重要的研究问题，可以通过许多不同英语变体的标准化数据首次在更大规模上进行调查。我们的大规模研究将补充目前的大规模研究，使我们能够考虑在整个20世纪的英语在一个无与伦比的规模的稳定和变化。英语的全球性意味着我们的研究结果将是有趣的和相关的大型国际非学术观众;他们将通过一个互动的声音映射网站，通过语言变化的创新和动态的可视化访问。除了对英语口语的新见解外，该项目还将为来自不同语言、不同格式和结构的许多数据集的大规模语音研究奠定重要基础。

Obtaining a data visualization of a text search within seconds via generic, large-scale search algorithms, such as Google n-gram viewer, is available to anyone. By contrast, speech research is only now entering its own 'big data' revolution. Historically, linguistic research has tended to carry out fine-grained analysis of a few aspects of speech from one or a few languages or dialects. The current scale of speech research studies has shaped our understanding of spoken language and the kinds of questions that we ask. Today, massive digital collections of transcribed speech are available from many different languages, gathered for many different purposes: from oral histories, to large datasets for training speech recognition systems, to legal and political interactions. Sophisticated speech processing tools exist to analyze these data, but require substantial technical skill. Given this confluence of data and tools, linguists have a new opportunity to answer fundamental questions about the nature and development of spoken language. Our project seeks to establish the key tools to enable large-scale speech research to become as powerful and pervasive as large-scale text mining. It is based on a partnership of three teams based in Scotland, Canada and the US. Together we will exploit methods from computing science and put them to work with tools and methods from speech science, linguistics and digital humanities, to discover how much the sounds of English across the Atlantic vary over space and time. We will develop an innovative and user-friendly software which exploits the availability of existing speech data and speech processing tools to facilitate large-scale integrated speech corpus analysis across many datasets together. The gains of such an approach are substantial: linguists will be able to scale up answers to existing research questions from one to many varieties of a language, and ask new and different questions about spoken language within and across social, regional, and cultural, contexts. Computational linguistics, speech technology, forensic and clinical linguistics researchers, who engage with variability in spoken language, will also benefit directly from our software. This project will also open up vast potential for those who already use digital scholarship for spoken language collections in the humanities and social sciences more broadly, e.g. literary scholars, sociologists, anthropologists, historians, political scientists. The possibility of ethically non-invasive inspection of speech and texts will allow analysts to uncover far more than is possible through textual analysis alone.Our project will develop and apply our new software to a global language, English, using 43 existing public and private spoken datasets of Old World (British Isles) and New World (North American) English, across an effective time span of more than 100 years, spanning the entire 20th century. Much of what we know about spoken English comes from influential studies on a few specific aspects of speech from one or two dialects. This vast literature has established important research questions which can be investigated for the first time on a much larger scale, through standardized data across many different varieties of English. Our large-scale study will complement current-scale studies, by enabling us to consider stability and change in English across the 20th century on an unparalleled scale. The global nature of English means that our findings will be interesting and relevant to a large international non-academic audience; they will be made accessible through an innovative and dynamic visualization of linguistic variation via an interactive sound mapping website. In addition to new insights into spoken English, this project will also lay the crucial groundwork for large-scale speech studies across many datasets from different languages, of different formats and structures.
