Yeah it was. At the risk of waxing about old history, when we demoed the first large vocabulary speech recognition system back in 1984 it ran on a bunch of IBM mainframes. Within two years it was running on a PC with some special purpose cards. Today much more powerful recognizers run locally on smartphones. We have always found we can shrink something down once we solve the basic problem, and it is important not to let computational limitations prevent you from seeing the best solution.
