Abstract
A computer system for user speech actuation of access to stored information, the system including a central processing unit, a memory and a user input/output interface including a microphone for input of user speech utterances and audible sound signal processing circuitry, and a file system for accessing and storing information in the memory of the computer. A speech recognition processor operating on the computer system recognizes words based on the input speech utterances of the user in accordance with a set of language/acoustic model and speech recognition search parameters. Software running on the CPU scans a document accessed by a web browser to form a web triggered word set from a selected subset of information in the document. The language/acoustic model and speech recognition search parameters are modified dynamically using the web triggered word set, and used by the speech recognition processor for generating a word string for input to the browser to initiate a change in the information accessed.
