Abstract: In a method of generating speech from text the speech segments necessary to put together the text to be output as speech by a terminal are determined; it is checked, which speech segments are already present in the terminal and which ones need to be transmitted from a server to the terminal; the segments to be transmitted to the terminal are indexed; the speech segments and the indices of segments to be output at the terminal are transmitted; an index sequence of speech segments to be put together to form the speech to be output is transmitted; and the segments are concatenated according to the index sequence. This method allows to realize a distributed speech synthesis system requiring only a low transmission capacity, a small memory and low computational power in the terminal.

Abstract: The present application relates to a user/vehicle-identification (ID) by which access rights privileges and or user settings can be associated to a specific user assigned to a specific vehicle (e.g. driver). In particular, the application relates to using a user/vehicle-ID stored in a car key remote control for associating access rights privileges and or user settings which have a relation to the vehicle, identified by the vehicle ID, to the user of the car key remote control.

Abstract: Telecommunication systems including a terminal, a switch and on Internet/Intranet having a memory for storing information blocks at locations defined by addresses, can be made more user-friendly by introducing a detector for detecting speech-recognition/non-speech recognition related parts in control signals originating from the terminal and defining the addresses or n response signals sent from memory to terminal and including said information blocks. A processor is coupled to the detector for routing, in dependence on the detection, routing (parts of) the signals to a server for either conversion of (parts of) the signals or for information purposes.
