Abstract

A hypertext navigation system that is controllable by spoken words have hypertext documents to which specific dictionaries and probability models for assisting in an acoustic voice recognition of hyper-links of this hypertext document are allocated. Control of a hypertext viewer or, respectively, browser and navigation in the hypertext document or hypertext system by pronouncing links is provided. The voice recognition is thereby optimally adapted to the links to be recognized without these having to be previously known.

Claims

1. A hypertext navigation system controllable by spoken words, comprising

a means for recognizing spoken language;

and

means for adapting said means for recognizing spoken language to contents of hypertext documents.

2. A hypertext document for use with a system for recognizing spoken language, comprising:

hypertext character sequences for hypertext navigation in said hypertext document; and

further data in said hypertext document, said further data assisting said system for recognizing spoken language in recognition of spoken words that correspond to said hypertext character sequences of said hypertext document.

3. A hypertext document according to

claim 2

, wherein said further data include a dictionary and a probability model, said dictionary containing said hypertext character sequences of said hypertext document and phoneme sequences allocated to said hypertext character sequences as entries, and wherein said probability model includes probabilities for matching said phoneme sequences to spoken words to make it possible for said system for recognizing spoken language to allocate a spoken word or a sequence of spoken words to an entry of said dictionary.

4. A hypertext navigation system controllable by spoken words, comprising:

a means for recognizing spoken language;

means for adapting said means for recognizing to contents of hypertext documents, including

hypertext character sequences for hypertext navigation in said hypertext document; and

further data in said hypertext document, said further data assisting said system for recognizing spoken language in recognition of spoken words that correspond to said hypertext character sequences of said hypertext document.

5. A hypertext navigation system controllable by spoken words, comprising

a means for recognizing spoken language;

means for adapting said means for recognizing to contents of hypertext documents, including

hypertext character sequences for hypertext navigation in said hypertext document; and

further data in said hypertext document, said further data assisting said system for recognizing spoken language in recognition of spoken words that correspond to said hypertext character sequences of said hypertext document, wherein said further data include a dictionary and a probability model, said dictionary containing said hypertext character sequences of said hypertext document and phoneme sequences allocated to said hypertext character sequences as entries in said dictionary, and wherein said probability model makes it possible for said system for recognizing spoken language to allocate a spoken word or a sequence of spoken words to an entry of said dictionary.

6. A hypertext navigation system controllable by spoken words as claimed in

claim 5

, whereby said dictionary and said probability model allocated to a hypertext document or to a part of a hypertext document are produced at run time and the voice recognition system is reconfigured at run time.

7. A hypertext navigation system controllable by spoken words as claimed in

claim 5

, whereby, based on definition of a user, said dictionaries and said probability models that have been produced for at least portions of hypertext documents which have been already at least partially displayed are stored so that said dictionaries and said probability models are accessed in case of a renewed display of said at least portions of hypertext documents.

8. A hypertext navigation system controllable by spoken words, comprising

a) means for recognizing spoken language to allocate a spoken word or a sequence of spoken words to entries of a dictionary or of a plurality of dictionaries,

b) at least one first dictionary containing character sequences of a hypertext document serving a purpose of hypertext navigation and containing phoneme sequences allocated to said character sequences as entries;

and

c) at least one second dictionary that contains instructions of the hypertext navigation system as entries.

9. A hypertext navigation system controllable by spoken words, comprising:

a) means for recognizing spoken language to allocate a spoken word or a sequence of spoken words to entries of a dictionary or of a plurality of dictionaries;

b) at least one dictionary containing character sequences of a hypertext document serving a purpose of hypertext navigation and containing phoneme sequences allocated to said character sequences as entries, at least a portion of said at least one dictionary containing instructions of the hypertext navigation system as entries.

10. A hypertext navigation system controllable by spoken words as claimed in

claim 9

, wherein said hypertext navigation system is selectively controllable in a traditional way by selection of character sequences using a pointing device.

12. A method as claimed in

claim 9

, further comprising the step of:

entering instructions of the hypertext navigation system together with phoneme seqeunces corresponding to said instructions into said dictionary in addition to said character sequences that serve the purpose of hypertext navigation.

11. A method for generating a hypertext document having a dictionary and a probability model, said dictionary containing said hypertext character sequences of said hypertext document and phoneme sequences allocated to said hypertext character sequences as entries, and wherein said probability model makes it possible for said system for said system for recognizing spoken language to allocate a spoken word or a sequence of spoken words to an entry of said dictionary from a traditional hypertext document, comprising the steps of

investigating a source text of a traditional hypertext document for character sequences that serve a purpose of hypertext navigation,

extracting said character sequences from said source text,

allocating phoneme sequences to said character sequences,

entering said character sequences and appertaining phoneme sequences into a dictionary;

and

producing a probability model for an acoustic voice recognition system for entries of said dictionary.
