语音注释数据库的查询

Querying Databases of Annotated Speech

Steve Cassidy, Steven Bird

摘要:

注释语音语料库是由信号数据以及时间对齐的符号“转录”组成的数据库。这种数据库通常是多维的、异构的和动态的。这些属性为表示和查询提出了许多严峻的挑战。数据的时间性质增加了额外的复杂性。本文介绍和协调两个独立的努力,模型注释语音数据库,一个在麦考瑞大学,一个在宾夕法尼亚大学。描述了各种查询语言,以及对各种分析问题的说明性应用。这里报告的研究构成了几个正在进行的项目的一部分,开发独立于平台的开源工具,用于创建,浏览,搜索,查询和转换语言数据库,并在互联网上传播大型语言数据库。

英文摘要:

Annotated speech corpora are databases consisting of signal data along with time-aligned symbolic `transcriptions'. Such databases are typically multidimensional, heterogeneous and dynamic. These properties present a number of tough challenges for representation and query. The temporal nature of the data adds an additional layer of complexity. This paper presents and harmonises two independent efforts to model annotated speech databases, one at Macquarie University and one at the University of Pennsylvania. Various query languages are described, along with illustrative applications to a variety of analytical problems. The research reported here forms a part of several ongoing projects to develop platform-independent open-source tools for creating, browsing, searching, querying and transforming linguistic databases, and to disseminate large linguistic databases over the internet.
