Although\n   lots of studies have been performed to solve this problem, the operation of\n   existing voice activity detection (VAD) algorithms is still far away from\n   ideal. This paper proposes a novel robust feature for VAD method that is\n   based on multi-valued coarsegraining Lempel-Ziv Complexity (MLZC), which is\n   an improved algorithm of the binary coarse-graining Lempel-Ziv Complexity\n   (BLZC). In addition, we use fuzzy c-Means clustering algorithm and the\n   Bayesian information criterion algorithm to estimate the thresholds of the\n   MLZC characteristic, and adopt the dual-thresholds method for VAD.\n   Experimental results on the TIMIT continuous speech database show that at low\n   SNR environments, the detection performance of the proposed MLZC method is\n   superior to the VAD in GSM ARM, G.729 and BLZC method.<\/jats:p>","DOI":"10.2298\/csis100906032z","type":"journal-article","created":{"date-parts":[[2011,7,7]],"date-time":"2011-07-07T11:10:09Z","timestamp":1310037009000},"page":"869-888","source":"Crossref","is-referenced-by-count":6,"title":["Voice activity detection method based on multivalued coarse-graining Lempel-Ziv complexity"],"prefix":"10.2298","volume":"8","author":[{"given":"Huan","family":"Zhao","sequence":"first","affiliation":[{"name":"School of Information Science and Engineering, Hunan University, Changsha, P.R.
