The inventive system can automatically annotate the relationship of text and acoustic units for the purposes of: (a) predicting how the text is to be pronounced as expressively synthesized speech, and (b) improving the proportion of expressively uttered speech as correctly identified text representing the speaker's message. The system can automatically annotate text corpora for relationships of uttered speech for a particular speaking style and for acoustic units in terms of context and content of the text to the utterances. The inventive system can use kinesthetically defined expressive speech production phonetics that are recognizable and controllable according to kinesensic feedback principles. In speech synthesis embodiments of the invention, the text annotations can specify how the text is to be expressively pronounced as synthesized speech. Also, acoustically-identifying features for dialects or mispronunciations can be identified so as to expressively synthesize alternative dialects or stylistic mispronunciations for a speaker from a given text. In speech recognition embodiments of the invention, each text annotation can be uniquely identified from the corresponding acoustic features of a unit of uttered speech to correctly identify the corresponding text. By employing a method of rules-based text annotation, the invention enables expressiveness to be altered to reflect syntactic, semantic, and/or discourse circumstances found in text to be synthesized or in an uttered message.
