18. A computer program product for providing language translation between first and second communication terminals, the computer program product comprising a non-transitory computer readable storage medium having computer readable program code embodied therein that, when executed by a processor, causes the processor to: establish communication between the first and second communication terminals; map a signal received from the first communication terminal to machine-readable intermediate data indicative of sounds in a first human language, wherein the signal represents speech in the first human language and comprises features extracted according to a parametric model that is different than that used by the first communication terminal when operating in a non-language translation mode; translate the machine-readable intermediate data indicative of sounds in the first human language to further machine-readable intermediate data indicative of sounds in a second human language; generate a translated signal representing speech and/or text in the second human language, which is different from the first human language, in response to the further intermediate data, the speech and/or text represented by the translated signal having a meaning corresponding to that of the speech represented by the received signal; and provide the translated signal to the second communication terminal, wherein, when executed by the processor, the computer readable program code further causes the processor to: provide a request to the first communication terminal to use the parametric model to generate resenting speech in the first human language, wherein the signal representing speech in the first human language is received from the first communication terminal in response to the request to provide automatic capability negotiation between a language translation device and the first communication terminal.
19. The computer program product of claim 18 , wherein the signal representing speech in the first human language is more error resilient than a vocoded signal with respect to radio transmission.
