1. A method for enhancing intelligibility of spoken words projected into an area of ambient noise from a loudspeaker system that receives an input signal derived from an electrical voice signal representing spoken words having formants, said method comprising the steps of: generating an electrical voice signal that represents spoken words having formants, amplifying individual ones of said formants of said spoken words by controlled amounts, weighting the amount of amplification of different ones of said formants by mutually different weighting values, combining said amplified weighted formants of said spoken word to generate an enhanced voice signal representing said spoken words, and feeding said enhanced voice signal to a loudspeaker system to be projected as sound into an area of ambient noise.
