Speech is one of the most natural and certain ways of human communication, and the recent progress of speech recognition technology is tremendous. Databases are the integrated information resources of various types of enterprises, and their values are increasing depending on the computerization of societies. However, in most cases, the database accesses are done by using the traditional keywords. This situation is deplorable since the society is now moving to mobile and ubiquitous one, where people are hard to use keyboard to obtain information. This research tried to resolve this problem by building a speech interface to a relational database system. We have implemented a system which consists of a Sun workstation, Oracle 7 a relational database management system, DS200 a speech recognition system, and FINE TALK a speech composition system. We have developed four software modules to combine such system components. The evaluation of the prototype was done, and it was revealed out that homonym problem should be resolved as well as how to accommodate incomplete Japanese sentence speeches. In this research, we have attached the first problem, and showed a solution by introducing the "instance keys, " which are the generalization of the traditional keys defined by using functional dependencies. It was shown that a more sophisticated speech interface can be realized by pursuing the proposed approach.

语音是人类最自然、最确定的交流方式之一，语音识别技术近年来取得了巨大的进步。数据库是各类企业的综合信息资源，其价值随着社会的信息化而不断提高。然而，在大多数情况下，数据库访问是通过使用传统的关键字来完成的。这种情况是可悲的，因为社会现在正在走向移动的和无处不在的一个，人们很难使用键盘获得信息。本研究试图通过建立一个语音接口到关系数据库系统来解决这个问题。我们实现了一个由Sun工作站、Oracle7关系数据库管理系统、DS200语音识别系统和FINE TALK语音合成系统组成的语音合成系统。我们已经开发了四个软件模块来联合收割机这样的系统组件。对原型进行了评价，并指出了需要解决的同音异义词问题以及如何容纳不完整的日语语句。在本研究中，我们附加了第一个问题，并通过引入“实例键”来解决，实例键是传统的使用函数依赖定义的键的推广。结果表明，一个更复杂的语音接口可以实现所提出的方法。
