17. A system comprising: one or more computers; and one or more storage devices storing instructions that are operable, when executed by the one or more computers, to cause the one or more computers to perform operations comprising: receiving an utterance that includes (i) a first term that indicates the particular entity type, (ii) a second term that indicates an entity name, and (iii) a third term that is associated with the particular geographic area; determining a candidate transcription of the utterance, the candidate transcription including a type term corresponding to the first term, a name term corresponding to the second term, and a geographic term corresponding to the third term; determining that the candidate transcription includes (i) the type term, (ii) the name term, and (iii) the geographic term; in response to determining that the candidate transcription includes (i) the type term, (ii) the name term, and (iii) the geographic term, determining that, among the phonetic representations indicated in the records in the entity-type specific, geo-localized entity database for the particular geographic area, a phonetic representation of the second term matches a particular phonetic representation of a particular canonical name of a set of canonical names associated with a particular entity; and in response to determining that, among the phonetic representations indicated in the records in the entity-type specific, geo-localized entity database for the particular geographic area, the phonetic representation of the second term matches the particular phonetic representation of the particular canonical name of the set of canonical names associated with the particular entity, outputting the reference name associated with the particular entity as a transcription of the second term.
17. A system comprising: one or more computers; and one or more storage devices storing instructions that are operable, when executed by the one or more computers, to cause the one or more computers to perform operations comprising: receiving an utterance that includes (i) a first term that indicates the particular entity type, (ii) a second term that indicates an entity name, and (iii) a third term that is associated with the particular geographic area; determining a candidate transcription of the utterance, the candidate transcription including a type term corresponding to the first term, a name term corresponding to the second term, and a geographic term corresponding to the third term; determining that the candidate transcription includes (i) the type term, (ii) the name term, and (iii) the geographic term; in response to determining that the candidate transcription includes (i) the type term, (ii) the name term, and (iii) the geographic term, determining that, among the phonetic representations indicated in the records in the entity-type specific, geo-localized entity database for the particular geographic area, a phonetic representation of the second term matches a particular phonetic representation of a particular canonical name of a set of canonical names associated with a particular entity; and in response to determining that, among the phonetic representations indicated in the records in the entity-type specific, geo-localized entity database for the particular geographic area, the phonetic representation of the second term matches the particular phonetic representation of the particular canonical name of the set of canonical names associated with the particular entity, outputting the reference name associated with the particular entity as a transcription of the second term. 19. The system of claim 17 , the operations comprising: determining a candidate transcription of the utterance, the candidate transcription including a type term corresponding to the first term and a name term corresponding to the second term; determining a geographic location corresponding to the utterance; and determining that the name term does not match a reference name of an entity (i) of the entity type corresponding to the type term and (ii) in a geographic location matching the geographic location, wherein determining that, among the phonetic representations indicated in the records in the entity-type specific, geo-localized entity database for the particular geographic area, a phonetic representation of the second term matches a particular phonetic representation of a particular canonical name of a set of canonical names associated with a particular entity is in response to determining that the name term does not match the reference name of the entity (i) of the entity type corresponding to the type term and (ii) in the geographic location matching the geographic location.
