System and method for a cooperative conversational voice user interface
First Claim
1. A computer-implemented method of facilitating natural language system responses utilizing accumulated short-term and long-term knowledge, the method being implemented by a computer system that includes one or more physical processors executing one or more computer program instructions which, when executed, perform the method, the method comprising:
- accumulating, by the computer system, short-term knowledge based on one or more natural language utterances received during a predetermined time period;
expiring, by the computer system, one or more items of short-term knowledge that are based on one or more natural language utterances received prior to the predetermined time period;
accumulating, by the computer system, long-term knowledge based on one or more natural language utterances received prior to the predetermined time period, wherein the long-term knowledge includes at least one of the one or more expired items of short-term knowledge;
receiving, at the computer system, a first natural language utterance via an input device;
determining, by the computer system, based on the short-term knowledge and the long-term knowledge, a first context for the first natural language utterance;
determining, by the computer system, based on the first context, an interpretation of the first natural language utterance; and
generating, by the computer system, a first response to the first natural language utterance based on the interpretation.

Abstract
A cooperative conversational voice user interface is provided. The cooperative conversational voice user interface may build upon short-term and long-term shared knowledge to generate one or more explicit and/or implicit hypotheses about an intent of a user utterance. The hypotheses may be ranked based on varying degrees of certainty, and an adaptive response may be generated for the user. Responses may be worded based on the degrees of certainty and to frame an appropriate domain for a subsequent utterance. In one implementation, misrecognitions may be tolerated, and conversational course may be corrected based on subsequent utterances and/or responses.

10. A system for facilitating natural language system responses utilizing accumulated short-term and long-term knowledge, the system comprising:
one or more physical processors programmed with one or more computer program instructions which, when executed, configure the one or more physical processors to; accumulate short-term knowledge based on one or more natural language utterances received during a predetermined time period; expire one or more items of short-term knowledge that are based on one or more natural language utterances received prior to the predetermined time period; accumulate long-term knowledge based on one or more natural language utterances received prior to the predetermined time period, wherein the long-term knowledge includes at least one of the one or more expired items of short-term knowledge; receive a first natural language utterance via an input device; determine a first context for the first natural language utterance based on the short-term knowledge and the long-term knowledge; determine an interpretation of the first natural language utterance based on the first context; and generate a first response to the first natural language utterance based on the interpretation. - View Dependent Claims (11, 12, 13, 14, 15, 16, 17, 18)
