咳嗽是人体清除呼吸道内的分泌物或异物的保护性呼吸反射动作,其强度和发生频率为临床的诊断和疗效评估提供了重要信息。介绍一种针对非特定人的咳嗽音识别系统,该系统基于 WINCE4.2,通过 MFCC 特征提取和 DTW 算法匹配,较好的完成了对咳嗽音的检测,并采用 SQLCE 作为数据存储管理后台,同时实现了 WINCE 平台和 PC 平台的数据同步处理,使得咳嗽数据的收集工作变得十分容易。通过临床实验证明,系统已经能够稳定有效地进行咳嗽音的检测和存储。此外,系统对咳嗽的频率和强度进行了初步的统计,为后续的咳嗽音分类分析和用药的疗效分析提供地基本的分析数据。

Cough is the body clearance of airway secretions or foreign objects inside the protective breathing reflex,the intensity and frequency of occurrence provides important information for clinical diagno-sis and curative effect evaluation.This paper introduces a non-specific human cough sound recognition sys-tem.the system is based on WINCE4.2,using MFCC DTW algorithm,fullfill the detection of the cough sound,and using SQLCE as data storage management,while achieving a wince platform and PC data syn-chronization platform,making data collection cough becomes very easy.Through clinical experiments prove that the system is stable,can conduct effective cough sound detection and storage.In addition,the system make statistics on the intensity and frequency of cough,which is the basic analytical data for subsequent a-nalysis of classification of cough sound and analysis of drug efficacy,etc.
