语音端点检测算法在猪咳嗽检测中的应用研究
Application of end point detection in pig cough signal detection
摘要
Abstract
Aiming at the low efficiency artificial diagnosis in large pig farms ,we had a study on the pig cough sound signal and pro‐posed an automation detection scheme of the pig cough sound .Considering the characteristics of the pig cough sound signal ,we made some improvements of the endpoint detection algorithm which is widely used in speech recognition ,and applied it in the pig cough sound signal detection .The scheme provides the effective signal for the artificial and automated diagnosis of the pig cough related diseases .We verified the scheme in 150 pig cough recordings ,the detection correct rate was above 96% .The error detec‐tion rate was lower than 4% ,so the detection scheme is effective and practical .关键词
