1. A method for modifying synthesized speech, the method including the steps of:

  • generating synthesized speech based on textual input and a plurality of run-time control parameter values;

    generating real-time data based on background noise contained in an environment in which the speech is reproduced;

    converting the background noise into an electrical signal;

    retrieving one or more interface models from a model database;

    characterizing the background noise with the real-time data based on the electrical signal and the interface models; and

    , modifying one or more of the run-time control parameter values based on the real-time data such that the intelligibility of the speech increases.
