Pokročilé modelování prozodie

Formální model prozodie pro systémy převodu textu na řeč. Model je založen na generativní gramatice abstraktních funkčně zapojených jednotek.A formal prosody model is proposed together with its application in a text-to-speech system. The model is based on a generative grammar of abstract prosodic functionally involved units. This grammar creates for each sentence a structure of immediate prosodic constituents in the form of a tree. Each prosodic word of a sentence is assigned with a description vector by a description function and this vector is used by a realization function to create appropriate intonation for the prosodic word. Parameters of the model are automatically set up using real speech data from a prosody corpus, which is also described
