摘要：
This paper presents a novel speech detection method for a microphone array system that is able to effectively detect voice-only events and distinguish against non-speech and speech-like sounds. The method is robust and suitable for a highly attenuated fax-field recordings environment. Using a new 2-dimensional feature set derived from the knowledge of speech production and noise generation, the proposed method has shown its effectiveness in broad-class sound classification, which is observed in the real data Simulation shown in this paper.
