1. A computer-implemented system comprising:

  • one or more processors;

    a recognition component that is executable by the one or more processors to receive a partial query input as voice signals of a user with at least one other sensed input type comprising text, image or audio;

    a classifier component, executable by the one or more processors, that processes the partial query input and infers in real-time multiple different search goals based on the partial query input by accessing one or more query databases that store query information and from which similar or matching character sets, terms or phrases are derived for generating at least one complete query, the classifier comprising a support vector machine to find a hyperspace in a space of possible inputs to distinguish triggering input events from non-triggering input events, the classifier explicitly trained using generic training data and implicitly trained by observing user behavior;

    a query formulation component, executable by the one or more processors, that generates the at least one complete query based on the multiple different search goals; and

    a search engine, executable by the one or more processors, that receives the at least one complete query, presents the at least one complete query to the user for editing, and processes the at least one complete query to return search results for each of the at least one complete query, the search results based on a confidence value output by the voice recognition component indicating the confidence of converted voice signals relative to the partial query input as voice signals of the user.
