Abstract:
1. A voice reinforcement system, comprising: a reflective boundary to reflect a voice signal from a speaker toward a listening location, the listening location spaced apart from a location of the speaker; a microphone, located between the speaker and the reflective boundary, to convert the voice signal to an intermediate electrical signal, where the microphone is spaced apart from the reflective boundary; a filter to extract a portion of the intermediate electrical signal representing a consonant sound from the voice signal to an extracted signal, the extracted signal based on frequency content of the intermediate electrical signal; an amplifier to amplify the extracted signal to an amplified signal; and a converter to convert the amplified signal into an audible signal that is directed toward the listening location and is substantially in-phase with a portion of the reflected voice signal to generate a reinforced signal formed from a summation of a portion of the amplified signal and the portion of the reflected voice signal.
