July 24, 2012 -- For voice processing it is important to ensure that the signal to be analyzed actually contains relevant information, especially if the system is operating in a real-time. This article presents an IP core speech detector for real-time systems, focusing on identification of segments of silence or voice, used in pre-processing of input signals to speaker recognition and verification systems. The IP core was designed to be able to be adapted to different environments of use and based on energy of samples to classify them as voice or silence.
