This paper adresses the important problem of speech detection. It describes the implementation of 3 speech detection methods and compares their performance under different signal-to-noise ratio (SNR) and stationarity conditions. The method that dynamically adjusts its thresholds is found to be the most reliable, even under very adverse recording conditions. Yet it is of low complexity and has a very moderate processing delay.
