1. A method identifying potential cause for a phrase search false positive when searching audio interaction objects, the method comprising:

  • using a processor conducting automatic speech recognition (ASR) to search for a first phrase in a set of objects to produce ASR results comprising identification of one or more objects identified by ASR as including the first phrase;

    producing using the processor a list of phonetic references comprising references to one or more objects identified by phonetic search as including the first phrase by searching for the first phrase in the set of objects using phonetic search;

    at the processor using output produced by the ASR to determine, using a phrase identification and query generation unit, whether or not a reference in the list of phonetic references points to a phrase that is the same as the first phrase;

    if it is determined that the reference points to a second phrase that is different from the first phrase then marking by the processor the second phrase as a potential cause for the phrase search false positive;

    displaying a list of potential causes for the phrase search false positive with respect to the first phrase to a user;

    accepting an input from the user, the input comprising a potential cause for the phrase search false positive from the display; and

    based on the input creating an operator designed to cause a query for searching the first phrase to omit the potential cause for the phrase search false positive in the input from a response of the query.
