听诊器听诊已成为诊断呼吸系统疾病的重要工具。尽管听诊是无创、快速且廉价的，但它具有固有的局限性，例如听者之间的差异性和主观性，并且检查必须面对面进行。传统听诊器无法记录呼吸音，因此无法共享声音。最近的创新数字听诊器克服了这些限制，使临床医生能够存储和共享声音以进行教育和讨论。特别是，可记录听诊器使得使用人工智能（特别是基于神经网络）分析呼吸音成为可能。具有自动特征提取器和卷积神经网络分类器的基于深度学习的分析已应用于呼吸音的准确分析。此外，当前电池技术、低功耗嵌入式处理器和集成传感器的进步使得可穿戴和无线听诊器的开发成为可能，这可以帮助检查生活在医生短缺地区或需要隔离的患者。仍然存在需要克服的挑战，例如复杂和混合呼吸音的分析以及噪声过滤，但持续的研究和技术发展将有助于向可穿戴和智能听诊器的新时代过渡。
Auscultation with stethoscope has been an essential tool for diagnosing the patients with respiratory disease. Although auscultation is non-invasive, rapid, and inexpensive, it has intrinsic limitations such as inter-listener variability and subjectivity, and the examination must be performed face-to-face. Conventional stethoscope could not record the respiratory sounds, so it was impossible to share the sounds. Recent innovative digital stethoscopes have overcome the limitations and enabled clinicians to store and share the sounds for education and discussion. In particular, the recordable stethoscope made it possible to analyze breathing sounds using artificial intelligence, especially based on neural network. Deep learning-based analysis with an automatic feature extractor and convoluted neural network classifier has been applied for the accurate analysis of respiratory sounds. In addition, the current advances in battery technology, embedded processors with low power consumption, and integrated sensors make possible the development of wearable and wireless stethoscopes, which can help to examine patients living in areas of a shortage of doctors or those who need isolation. There are still challenges to overcome, such as the analysis of complex and mixed respiratory sounds and noise filtering, but continuous research and technological development will facilitate the transition to a new era of a wearable and smart stethoscope.
