1. A computer-implementable method for synthesizing audible speech, with varying prosody, from textual content, the method comprising: generating first texts annotated with prosody information, the first texts and prosody information generated by a speech recognition engine applied to speech inputs and parameters; training an inventory of prosody models with the first texts annotated with prosody information, wherein the prosody models are associated with the parameters; 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 second text; applying the associated prosody models to the different segments of the second text to produce prosody annotations for the second text; reconciling conflicting prosody annotations from multiple prosody models associated with a segment of the second text; and synthesizing audible speech from the second text and the reconciled prosody annotations.
