1. At least one computer-readable storage device encoded with a speech synthesis program which causes a system for synthesizing speech from text to perform:

  • determining a first speech segment sequence corresponding to an input text, by selecting speech segments from a speech segment database according to a first cost calculated based at least in part on a statistical model of prosody variations;

    determining prosody modification values for the first speech segment sequence, after the first speech segment sequence is selected, by using a second cost calculated based at least in part on the statistical model of prosody variations, wherein the first cost is different from the second cost; and

    applying the determined prosody modification values to the first speech segment sequence to produce a second speech segment sequence whose prosodic characteristics are different from prosodic characteristics of the first speech segment sequence.
