First Claim
1. A computer-implemented method, comprising:
- receiving multiple search queries;
identifying, for each search query of the received search queries, an entity associated with (i) the search query or (ii) a pair comprising the search query and an answer that a search engine generates in response to the search query;
after receiving the search queries, receiving a voice query that includes a pronoun;
identifying a plurality of acoustic parameters associated with the pronoun, wherein the identified plurality of acoustic parameters comprise two or more of volume, pitch, frequency, duration between each spoken word, and spoken duration of words or phrases;
selecting, from among the identified entities associated with (i) the search queries or (ii) the pairs that each comprise a search query and an answer that a search engine generates in response to the search query, a particular entity based at least on the identified plurality of acoustic parameters associated with the pronoun comprising two or more of volume, pitch, frequency, duration between each spoken word, and spoken duration of words or phrases;
modifying the voice query based at least on the selected entity; and
obtaining an answer that the search engine generates in response to the modified search query.

Abstract
Methods, systems, and apparatus, including computer programs encoded on computer storage media, for resolving ambiguity in received voice queries. An original voice query is received following one or more earlier voice queries, wherein the original voice query includes a pronoun or phrase. In one implementation, a plurality of acoustic parameters is identified for one or more words in the original voice query. A concept represented by the pronoun is identified based on the plurality of acoustic parameters, wherein the concept is associated with a particular query of the one or more earlier queries. The concept is associated with the pronoun. Alternatively, a concept may be associated with a phrase by using grammatical analysis of the query to relate the phrase to a concept derived from a prior query.
