摘要翻译：
文档错误增加了医疗保健成本，并导致不必要的病人死亡。作为诊断和计费的标准语言，ICD代码是全世界医疗文件的基础。尽管电子病历的普及，医院仍然见证了ICD错误编码的高水平。在这篇论文中，我们提出了用远场语音识别自动记录ICD码。当麦克风位于离源数米的地方时，就会发生远场语音，这在智能家居和安全系统中很常见。该方法将声信号处理与递归神经网络相结合，实现了实时识别和记录ICD码。为了评估我们的模型，我们收集了一个ICD-10码的远场语音数据集，发现我们的模型达到了87%的准确率，BLEU得分为85%。通过从一个无监督的医学语言模型中采样，我们的方法能够优于现有的方法。总之，这项工作显示了自动语音识别在提供高效、准确和成本效益高的医疗保健文档方面的潜力。

一级分类：Computer Science        计算机科学
二级分类：Computation and Language        计算与语言
分类描述：Covers natural language processing. Roughly includes material in ACM Subject Class I.2.7. Note that work on artificial languages (programming languages, logics, formal systems) that does not explicitly address natural-language issues broadly construed (natural-language processing, computational linguistics, speech, text retrieval, etc.) is not appropriate for this area.
涵盖自然语言处理。大致包括ACM科目I.2.7类的材料。请注意，人工语言（编程语言、逻辑学、形式系统）的工作，如果没有明确地解决广义的自然语言问题（自然语言处理、计算语言学、语音、文本检索等），就不适合这个领域。

英文摘要：
  Documentation errors increase healthcare costs and cause unnecessary patient deaths. As the standard language for diagnoses and billing, ICD codes serve as the foundation for medical documentation worldwide. Despite the prevalence of electronic medical records, hospitals still witness high levels of ICD miscoding. In this paper, we propose to automatically document ICD codes with far-field speech recognition. Far-field speech occurs when the microphone is located several meters from the source, as is common with smart homes and security systems. Our method combines acoustic signal processing with recurrent neural networks to recognize and document ICD codes in real time. To evaluate our model, we collected a far-field speech dataset of ICD-10 codes and found our model to achieve 87% accuracy with a BLEU score of 85%. By sampling from an unsupervised medical language model, our method is able to outperform existing methods. Overall, this work shows the potential of automatic speech recognition to provide efficient, accurate, and cost-effective healthcare documentation.
