Abstract :
A processing-efficient algorithm which detects the presence of speech in a low signal-to-noise (SNR) environment is proposed. A single delay auto-correlation function is used to detect the speech, and a circular buffer prevents loss of the first portion of the signal while the decision is made. Performance measurements are provided for different channel conditions and noise types
