摘要： A network comprises a number of speech-enabled sites maintaining a number of voice pages. A central server on the network executes a voice browser which provides users with access to the sites using voice-activated hyperlinks. The server also maintains and brokers information associated with the users based on spoken dialogs between the users and the sites. In response to a user accessing a given ASR site, information about that user is provided by the server for use by that ASR site. The information is used by the ASR site to optimize a spoken dialog between the user and the ASR site by reducing the amount of information the user is required to provide during the dialog. Information about the user can thereby be shared between separate speech enabled sites, in a manner which is transparent to the user, in order to expedite the user's interaction with those sites.
摘要翻译：网络包括维持多个语音页面的许多支持语音的站点。网络上的中央服务器执行语音浏览器，该用户使用语音激活的超链接为用户提供访问站点的功能。服务器还根据用户和站点之间的语音对话来维护和经纪人与用户相关的信息。响应于访问给定ASR站点的用户，由该服务器提供关于该用户的信息以供该ASR站点使用。该信息由ASR站点通过减少用户在对话期间提供的信息量来优化用户和ASR站点之间的语音对话。因此，可以以对用户透明的方式，在单独的支持语音的站点之间共享关于用户的信息，以便加速用户与这些站点的交互。

摘要： A voice-enabled application, which may be a voice browser, is configured to provide active help to a user. The application maintains a usage history of each user with respect to dialog states. The usage history includes various user-specific variables, some of which are valid across multiple sessions. The application maintains a number of active help prompts capable of being played to a user as speech, each containing information on a different, specific help topic. The application further maintains a number of sets of conditions, each set corresponding to a different one of the active help prompts. The application monitors dialog states during a session of a user and generates an event based on the dialog states. The application applies certain ones of the conditions to certain ones of the user-specific variables in response to the event. The application then plays a active help prompt containing information on a specific help topic to the user if the applied conditions are satisfied.
摘要翻译：可以是语音浏览器的支持语音的应用被配置为向用户提供主动帮助。该应用程序维护每个用户相对于对话状态的使用历史。使用历史包括各种用户特定变量，其中一些变量在多个会话中有效。应用程序维护一些能够作为语音播放给用户的主动帮助提示，每个都包含有关不同的特定帮助主题的信息。应用程序进一步维护一组条件，每组条件对应于不同的一个主动帮助提示。应用程序在用户的会话期间监视对话状态，并基于对话状态生成事件。该应用程序将某些条件应用于响应于该事件的某些用户特定变量。如果应用条件得到满足，该应用程序将播放一个主动的帮助提示，其中包含有关特定帮助主题的信息给用户。
