VOICE/NON-VOICE DISCRIMINATION SYSTEM FOR PUBLIC COMMUNICATION NETWORKS
-
摘要: 本文分析了公用通信網(wǎng)中非話音信號傳輸?shù)奶攸c,提出并實現(xiàn)了萬門話路非話信號檢測系統(tǒng)的研制方案。該系統(tǒng)在國內(nèi)首次同時達到大容量,實時和極低虛警率的設(shè)計指標。Abstract: The features of non-voice signals on public communication nets are analysed and an approach to distinguish such signals is introduced in this paper. It is the first time for the system to meet three key targets: large-scale, high recognition rate and low false alarm at the same time.
