It is shown that even a simple feature such as full-band energy, when employed with a large-enough context, shows promise for further investigation. Experimental evaluations on the test data set, with a state-of-the-art multi-layer perceptron based SND system and a simple energy threshold based SND method, using the F-measure, show an absolute performance gain of $4.4\%$ and $5.4\%$ respectively, when used with a context of 1000 ms. ROC based performance evaluation also reveals promising performance for the proposed method, particularly in low SNR conditions.}, pdf = {https://publications.idiap.ch/attachments/reports/2008/parthasarathi-idiap-rr-08-21.pdf}, postscript = {ftp://ftp.idiap.ch/pub/reports/2008/parthasarathi-idiap-rr-08-21.ps.gz}, ipdmembership={speech}, }
