Voiced interface with hyperlinked information
First Claim
1. A method of facilitating the selection of a hyperlink from among a plurality of hyperlinks presented to a user in audio form, said method comprising the steps of:
- furnishing to said user a first signal representing speech utterances of said plurality of hyperlinks and one or more other words, wherein said signal includes an identification of said hyperlinks;
performing speech recognition on a second signal representing speech uttered by said user, said speech recognition being performed with use of a recognizer vocabulary which comprises entries corresponding to at least two of said hyperlinks said at least two of said hyperlinks having been provided within a sliding window of said plurality of hyperlinks presented in audio form, said sliding window including no more than a predetermined number of most recently provided hyperlinks of said plurality of hyperlinks presented in audio form.

Abstract
An improved audio browser is disclosed. In an exemplary embodiment, a plurality of hypertext links (hereafter called “hyperlink words”) available from, for example, a World Wide Web document, are used as a vocabulary of a speech recognizer for an audio browser. These hyperlink words are read to the user in the ordinary course of the audio browser'"'"'s “speaking voice”—such hyperlink words being identified to the user by, for example, a change in voice characteristics for the “speaking voice.” When a user wishes to select a hyperlink word, the user merely repeats the hyperlink word itself, rather than speaking a command or using a DTMF tone. The speech recognizer, which has as its vocabulary some or all of the hyperlink words of the document, recognizes the spoken hyperlink word and causes the jump to the linked address associated with the recognized hyperlink word.

20. A system for facilitating the selection of a hyperlink from among a plurality of hyperlinks presented to a user in audio form, said system comprising:
-
an interface providing to said user a first signal representing speech utterances of said plurality of hyperlinks and one or more other words, wherein said signal includes an identification of said hyperlinks;
a speech recognizer for performing speech recognition on a second signal representing speech uttered by said user, said speech recognition being performed with use of a recognizer vocabulary which comprises entries corresponding to at least two of said hyperlinks said at least two of said hyperlinks having been provided within a sliding window of said plurality of hyperlinks presented in audio form, said sliding window including no more than a predetermined number of most recently provided hyperlinks of said plurality of hyperlinks presented in audio form. - View Dependent Claims (21, 22, 23, 24, 25, 26, 27, 28, 29, 30, 31, 32, 33, 34, 35, 36)

37. A voiced information interface system comprising:
-
a database of information including text having one or more corresponding information links;
a means operating in conjunction with said database for causing information to be provided in voiced form;
a means for recognizing a voiced response by a user in relation to said provided information, said means for recognizing being more likely to recognize voiced information provided more recently by said means for causing information to be provided in voiced form than voiced information provided earlier by said means for causing information to be provided in voiced form; and
a means for shifting to information related to at least one of said information links in response to said recognized user response. - View Dependent Claims (38, 39, 40, 41, 42, 43, 44, 45, 46, 47)

48. A method for providing voiced access to stored information, wherein said information includes text having one or more corresponding information links, comprising the steps of:
-
causing at least a portion of said information to be provided in voiced form;
recognizing a voiced response by a user in relation to said provided information, a voiced response corresponding to information provided more recently being more likely to be recognized than a voiced response corresponding to information provided earlier; and
shifting to information related to at least one of said information links in response to said recognized user response. - View Dependent Claims (49, 50, 51, 52, 53, 54, 55, 56, 57, 58)

59. A system for providing an interface to a stored database of information comprising:
-
a means for providing said database of information as a set of linked information layers, wherein said information is stored in an audio form;
a means for causing a particular layer of said information to be provided to a user;
a means for recognizing a voiced response by said user in relation to information in said particular layer, a voiced response corresponding to information provided more recently being more likely to be recognized than a voiced response corresponding to information provided earlier; and
a means for operating on said recognized user response to effect a shift from said particular layer to a linked layer.

-
60. A system for providing an interface to a stored database of information comprising:
-
a means for establishing said database of information as a set of linked information layers, where linkage between such layers is related to linkage words in particular information layers;
a means operating in conjunction with said stored information layers for causing information in a given layer to be provided in voiced form, wherein said linkage words in said given layer are provided in an aurally distinct manner from other information in said given layer;
a means for recognizing a voiced response by a user in relation to one of said linkage words in said given layer, a voiced response corresponding to information provided more recently being more likely to be recognized relative to a voiced response corresponding to information provided earlier; and
a means for operating on said recognized voiced user response to effect a shift from said given layer to another layer linked to said linkage word.
