LET'S GO: Improved Speech Interfaces For The General Public

该项目研究老年人和非英语母语人士的口语系统。现有的系统是为普通用户构建的，因此对这些非传统人群表现不佳。老年人目前很少获得计算机化的信息，但他们有电话，如果信息以他们容易理解的方式呈现，他们就可以很容易地访问计算机。非母语人士很难被相同的对话系统理解，这些对话系统需要适应他们的语言，并帮助他们找到正确的表达方式。为了提高口语输出的可理解性，We‘s Go将调查词汇、韵律和频谱内容的差异，以使年长和非母语的听众更好地理解信息。为了改进口语输入，该项目将探索为目标人群调整输入语音信号的词汇和声学信息的统计模型。我们将通过创建一个口语演示器来评估其发现的相关性，该演示器允许老年人和非本地用户通过电话访问港务局公交信息。

This project investigates spoken language systems for the elderly and non-native speakers of English. Existing systems have been constructed for the average user and thus perform poorly for these nontraditional populations. The elderly have little access at present to computerized information, yet they have telephones that would enable them to access computers easily if the information were presented in a way that they could readily understand. Non-native speakers have difficulty being understood by the same dialogue systems, which need to be adapted to their speech and aid them in finding the correct way to express themselves. In order to improve the understandability of spoken output, Let's Go will investigate differences in lexical, prosodic and spectral content to enable elderly and non-native listeners to better understand the message. In order to improve spoken input, the project will explore adaptation of the statistical models of the lexical and acoustic information of the incoming speech signal for the target populations. Let's Go will assess the pertinence of its findings by creating a spoken language demonstrator that allows elderly and non-native users to access Port Authority Transit Bus information over the telephone.
