Abstract
A system may receive a voice search query and may determine word hypotheses for the voice query. Each word hypothesis may include one or more terms. The system may obtain a search query log and may determine, for each word hypothesis, a quantity of other search queries, in the search query log, that include the one or more terms. The system may determine weights based on the determined quantities. The system may generate, based on the weights, a first search query from the word hypotheses and may obtain a first set of search results. The system may modify, based on the first set of search results, one or more of the weights. The system may generate a second search query from the word hypotheses and obtain, based on the second search query, a second set of search results for the voice query.
