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.

A technique for synchronizing a visual browser and a voice browser. A visual browser is used to navigate through visual content, such as WML pages. During the navigation, the visual browser creates a historical record of events that have occurred during the navigation. The voice browser uses this historical record to navigate the content in the same manner as occurred on the visual browser, thereby synchronizing to a state equivalent to that of the visual browser. The creation of the historical record may be performed by using a script to trap events, where the script contains code that records the trapped events. The synchronization technique may be used with a multi-modal application that permits the mode of input / output (I / O) to be changed between visual and voice browsers. When the mode is changed from visual to voice, the record of events captured by the visual browser is provided to the voice browser, thereby allowing the I / O mode to change seamlessly from visual to voice. Likewise, the voice browser captures events which may be provided to the visual browser when the I / O mode is changed from voice to visual.

The grammar of the speech input to a voice service system is normally specified by the voice service system. However, this can produce problems in respect of idioms, such as dates, which are expressed different ways by different users. To facilitate the handling of idioms, a user is permitted to specify their own idiom grammar which is then used by the voice service system to interpret idioms in speech input from that user. Typically, the normal grammar of speech input is specified by grammar tags used to mark up a voice page script interpreted by a voice page browser; in this case, it will generally be the voice browser that is responsible for employing the user-specified idiom grammar to interpret the corresponding idiom in the speech input by the user. The user-specified grammar can be pre-specified directly to the voice browser by the user or fetched by the browser from a remote location on the fly.
