  • Abstract
    A new method for speech detection using a microphone array is proposed. An explicit expression is first deduced for representing the signal-to-noise ratio (SNR) of each signal segment. A constant SNR threshold is then used to discriminate between speech and nonspeech signals. Simulation results show that the proposed method outperforms the conventional energy detection method
