Abstract: The invention concerns a method for warning a user (17) equipped with a terminal (4, 5, 6, 67) during modification of a content in accordance with a content syndication technology in a communication system supporting a session initiation protocol and including a warning server (1) and a content server (2). The method is characterized in that it consists in: transmitting, from a terminal (4) of the user (17) to the warning server (1), a subscription message (9, 18) of said protocol identifying a content in conformity with said content syndication technology stored on the content server (2); receiving at the warning server (1), from the content server (2), an indication concerning a modification of said content; and transmitting a notifying message (11, 10, 23) of said protocol to said user (17), from the warning server (1), when an indication concerning a modification of said content has been received.

Abstract: A method for selecting acoustic units each of which contains a natural speech signal and symbolic parameters involves a stage (4) for determining at least one target symbolic unit sequence; a stage (5) for determining a contextual acoustic model sequence corresponding to the target sequence; a stage (6) for determining an acoustic template on the basis of the contextual acoustic model sequence and a stage (7) for selecting the acoustic unit sequence according to the acoustic template applied to the target symbolic unit sequence. The invention is used for voice synthesis.
