   摘要
   哮喘是一种儿童易患的慢性病。哮喘患儿生活质量往往比其他儿童差。内科和儿科医生建议家长记录哮喘发作频率和症状，以帮助管理其患儿的哮喘。然而，缺少一个监测哮喘病情的方便仪器导致很难管理哮喘，特别是对于幼年患儿。这项工作开发了一个家用哮鸣音监测系统。采用一个小型、柔软的听诊器来收集呼吸道声音。哮鸣音检测算法采用的是适应性呼吸频谱系数（RSACC)算法，此法具有高敏感性/特异性和低计算要求的优势。来自8例幼儿（1～7岁）的59种声音文件在急诊室被收集得到并进行分析。结果显示，该系统检测哮鸣音具有88%的敏感性和94%的特异性。总而言之，此种小型、柔软听诊器易于对幼儿使用。噪音的环境也不会影响哮鸣音的检测效力。因此，对于有评估和管理其患儿哮喘病情意愿的家长可在家使用此系统。

Abstract
Asthma is a chronic disease that is commonly suffered by children. Asthmatic children have a lower quality of life than other children. Physicians and pediatricians recommend that parents record the frequency of attacks and their symptoms to help manage their children's asthma. However, the lack of a convenient device for monitoring the asthmatic condition leads to the difficulties in managing it, especially when it is suffered by young children. This work develops a wheeze detection system for use at home. A small and soft stethoscope was used to collect the respiratory sound. The wheeze detection algorithm was the Adaptive Respiratory Spectrum Correlation Coefficient (RSACC) algorithm, which has the advantages of high sensitivity/specificity and a low computational requirement. Fifty-nine sound files from eight young children (one to seven years old) were collected in the emergency room and analyzed. The results revealed that the system provided 88% sensitivity and 94% specificity in wheeze detection. In conclusion, this small soft stethoscope can be easily used on young children. A noisy environment does not affect the effectiveness of the system in detecting wheeze. Hence, the system can be used at home by parents who wish to evaluate and manage the asthmatic condition of their children.
