Abstract: The invention concerns a method of providing a Push-to-Talk (=PTT) service within one or more telecommunication networks (1, 2, 3, 4) by means of a gateway-server (5) which sets up a virtual connection per PTT connection. The virtual connection provides information about the participating terminals (10, 20, 30, 40) of the PTT connection, the service type to reach each terminal (10, 20, 30, 40), and the connection status of each terminal (10, 20, 30, 40). Thus, the gateway-server (5) is capable of providing the PTT service within and/or across different telecommunication networks comprising radio access telecommunication networks (1), fixed wire-line telecommunication networks (2), circuit-switched telecommunication networks (3), and packet-switched telecommunication networks (4).

Abstract: The present invention relates to a push-to-talk server (6) and a method of performing a push-to-talk based communication service for registered users (21, 25 to 28) of a push-to-talk service. A push-to-talk call request is transmitted from a calling terminal (31) to the push-to-talk server (6), the push-to-talk call request requesting the establishment of a half-duplex communication connection to one or more called users (25 to 28) and/or user groups. The push-to-talk server (6) establishes an IP based streaming communication channel between the calling terminal (31) and a speech-to-text converter (74). A push-to-talk voice input is transmitted by said communication channel (91) from the calling terminal to the speech-to-text converter (74). The speech-to-text converter (74) converts the push-to-talk voice input to a text.

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: A method for establishing a digital communication link between an originating subscriber terminal and at least one called subscriber terminal, said method being better adapted to the transmission bandwidth used by a subscriber, has the following steps: First, a provisional link at a standard transmission rate from the originating subscriber terminal to the called subscriber is requested from a switching center. That provisional link is then established by the switching center. Next, a new, lower value for the transmission rate is selected by the originating subscriber terminal. That new value is then agreed upon with the switching center. Lastly, the latter switches the transmission rate of the provisional link over to the new, lower value, thus completing establishment of the communication link. The invention can advantageously be used in a telecommunications network, which for example operates according to the ISDN standard, to economize on transmission capacity and reduce call charges.

Abstract: There is known a telecommunication terminal with a miniature display for received, visually perceptible information, such as, for example, fax messages. In addition, a device is known for projecting computer images or TV images, the device comprising a so-called DMD chip (Digital Mirror Device). It is proposed to improve the aforedescribed telecommunication terminal (MS) by providing the terminal with projection means (DMD, FL) which can basically only be used for the device described above. In addition, the device described above is improved by being provided with an interface circuit for connection to a telecommunication terminal. Accordingly, the conventional means known in the field of computer technology and TV technology for projecting images are now used in or for a telecommunication terminal, especially in a mobile radio telephone (MS). With the received image data, images can be projected directly onto a projection screen, for example, onto a wall. Several people can view the images simultaneously.

Abstract: Distributed Speech Recognition (DSR) systems comprise terminals having a complex preprocessing unit and a network having a final processing unit. By leaving a Fast Fourier Transformation (FFT) together with a filtering function and a compression in said preprocessing unit by shifting both nonlinear transformation as well as a Discrete Cosine transformation (DCT) from said preprocessing unit into said final processing unit, where both follow decompression, said terminals are of a lower complexity. By using a MEL-filter (melody-filter) which preferably is adaptable, said low complex terminals are made more flexible.
