Abstract
Service architecture for providing to a user terminal of a communications network textual information and relative speech synthesis, the user terminal being provided with a speech synthesis engine and a basic database of speech waveforms includes: a content server for downloading textual information requested by means of a browser application on the user terminal; a context manager for extracting context information from the textual information requested by the user terminal; a context selector for selecting an incremental database of speech waveforms associated with extracted context information and for downloading the incremental database into the user terminal; a database manager on the user terminal for managing the composition of an enlarged database of speech waveforms for the speech synthesis engine including the basic and the incremental databases of speech waveforms.

23. A method of generating synthesized speech from textual information on a user terminal, said user terminal being provided with a speech synthesis engine having a basic database of speech waveforms, comprising the steps of:
-
extracting context information associated with said textual information; selecting an incremental database of speech waveforms associated with said context information; providing said user terminal with said incremental database; managing the composition of an enlarged database of speech waveforms comprising said basic and said incremental databases of speech waveforms; and converting into synthesized speech said downloaded textual information employing said enlarged database of speech waveforms. - View Dependent Claims (24, 25, 26, 27, 28, 29, 30, 31, 32, 44)
