Abstract

Management of multiple voice-controlled applications is provided employing registration and prioritization of applications and associated commands. In a multi-application environment, each application requests registration by a speech recognition interface. Upon registering the application(s), the interface assigns priorities to the active applications. Each application also submits a list of associated commands for registration. The interface selects a subset of submitted commands to be registered and assigned priorities. Speech recognition is performed based on the selected and prioritized commands to reduce interface overload and grammar conflict.
