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.

该项目研究老年人和非英语母语人士的口语系统。现有系统是为普通用户构建的，因此对于这些非传统人群来说表现不佳。目前，老年人很少能接触到计算机化的信息，但他们拥有电话，如果信息以他们容易理解的方式呈现，他们就可以轻松地访问计算机。 非母语人士很难被相同的对话系统所理解，这些对话系统需要适应他们的言语并帮助他们找到表达自己的正确方式。 为了提高口语输出的可理解性，Let's Go 将研究词汇、韵律和频谱内容的差异，以使老年人和非母语听众更好地理解信息。 为了改善语音输入，该项目将探索针对目标人群调整传入语音信号的词汇和声学信息的统计模型。 Let's Go 将通过创建一个口语演示器来评估其研究结果的相关性，该演示器允许老年人和非母语用户通过电话访问港务局公交信息。
