Abstract: Voice product search requests in a product catalog are improved by identifying search refinements versus new search requests and by applying filters of departments to identify sub-sets of the product catalog to search based on the search string. The systems and methods described herein provide for analysis of voice search data, identification of departments within a product catalog that may be applicable to the search request and the search refinement, limiting the scope of the search, matching the voice input to an attribute type, and performing the refinement on the search results.
