Speech interface system and method for control and interaction with applications on a computing system

摘要

A speech processing system which exploits statistical modeling and formal logic to receive and process speech input, which may represent data to be received, such as dictation, or commands to be processed by an operating system, application or process. A command dictionary and dynamic grammars are used in processing speech input to identify, disambiguate and extract commands. The logical processing scheme ensures that putative commands are complete and unambiguous before processing. Context sensitivity may be employed to differentiate data and commands. A multi faceted graphic user interface may be provided for interaction with a user to speech enable interaction with applications and processes that do not necessarily have native support for speech input.

1. A speech processing method, comprising:
storing a representation of at least one of a command and a stream of data generated based on received speech; automatically analyzing the stored representation to distinguish between a command structure and dictation; automatically analyzing a grammar of the received speech in a command mode, to determine a command structure deficiency with respect to command ambiguity and command completeness; automatically generating a prompt to remedy the command structure deficiency, in a contextually appropriate manner; after the command structure deficiency is remediated, generating an output representing the command, automatically preserving a prior state of a system, and automatically executing the command on the automated data processing system; and after the executing of the command on the automated data processing system, restoring the prior state of the system other than changes in a state of the system resulting from the executing of the command.
