PL
Opracowanie bezpiecznego systemu transmisji mowy nie jest trywialnym zadaniem. Media przewodowe, z uwagi na niezawodność i odporność na uszkodzenia mechaniczne, zdają się być idealnym rozwiązaniem. Kabel BPL (Broadband over Power Line) jest odporny na przerwy w dostawie prądu i częściowe uszkodzenie przewodników fazowych, zapewniając ciągłość transmisji w przypadku awarii. Wydaje się odpowiednim narzędziem do dostarczania istotnych danych, w szczególności wyraźnych i zrozumiałych komunikatów głosowych. Artykuł ten opisuje taki system, który został opracowany oraz zbadany w rzeczywistych warunkach pracy. Obejmował on dwukierunkową transmisję próbek mowy w języku angielskim (amerykańskim) oraz polskim. Skuteczność zaprojektowanego rozwiązania została oceniona w badaniu subiektywnym na grupie 15 osób.

Designing a secured voice transmission system is not a trivial task. Wired media, thanks to their reliability and resistance to mechanical damage, seem an ideal solution. The BPL (Broadband over Power Line) cable is resistant to electricity stoppage and partial damage of phase conductors, ensuring continuity of transmission in case of an emergency. It seems an appropriate tool for delivering critical data, mostly clear and understandable voice messages. This paper describes such a system that was designed and evaluated in real-time operating conditions. It involved a two-way transmission of speech samples in American English and Polish. The efficiency of the designed solution was evaluated in the subjective study on a group of 15 people.
