1. A computer-implementable method for synthesizing audible speech, with varying prosody, from textual content, the method comprising: maintaining an inventory of prosody models with lexicons, selecting a subset of multiple prosody models from the inventory of prosody models; associating prosody models in the subset of multiple prosody models with different segments of a text based on phrases in the text statistically associated with the lexicons of the prosody models; applying the associated prosody models to the different segments of the text to produce prosody annotations of the text; considering annotations of the prosody annotations to reconcile conflicting prosody annotations of the text previously produced by multiple prosody models associated with a segment of the text; and synthesizing audible speech from the text and the reconciled prosody annotations.
