  • receiving, from the speech-enabled application, input comprising a plurality of text strings;

    identifying a first portion of a first text string of the plurality of text strings as differing from a corresponding first portion of a second text string of the plurality of text strings, and a second portion of the first text string as not differing from a corresponding second portion of the second text string;

    assigning contrastive stress to the identified first portion of the first text string, but not to the identified second portion of the first text string;

    generating, using at least one computer system, speech synthesis output to render the plurality of text strings as speech having the assigned contrastive stress; and
