Claim 10:
11. A system for improving content discovery in response to a voice query, the system comprising:
memory; and
control circuitry configured to:
generate a transcription of a voice query;
determine whether the transcription includes a trigger term indicating that an intent of the voice query is to correct a previous voice query; and
in response to determining that the transcription includes a rigger trigger term:
identify, based on the transcription and data, retrieved from the memory, associated with the previous voice query, a first term of the voice query that is similar to a second term of the previous voice query;
temporarily increase, for the first term, a relaxation rate of an entity recognition model, wherein a number of interpretations considered for the first term is based on the relaxation rate;
identify a plurality of candidate entities to which the first term refers using the entity recognition model and based on the increased relaxation rate;
perform a search based on the plurality of candidate entities and the data associated with the previous voice query; and
generate for output a search result of the search.
