1. A computer-implemented interface, comprising:

  • a set of parsers configured to parse information received from a plurality of sources including a mixed modality of inputs;

    a discourse manager configured to;

    identify correlations in the information;

    interpret the mixed modality of inputs based on environmental data associated with at least one of the mixed modality of inputs;

    based on the identified correlations and the interpreted mixed modality of inputs, at least one of determine or infer an intent associated with the information; and

    generate a confidence level for the intent as a function of the environmental data; and

    a response manager configured to;

    evaluate a first input of the mixed modality of inputs, the first input having a first modality initially employed as a primary modality;

    based on the generated confidence level, provide feedback to request a second input having a second modality different from the first modality; and

    substitute the second modality for the first modality as the primary modality until the environmental data changes.
