关鑫，外国语言学及应用语言学博士生，法律语言学方向。
研究兴趣
涉及话语分析、语篇信息分析、司法语音识别领域。
主要研究方向
讲话人司法识别研究。
讲话人司法识别技术
是专家分析比对涉案检材语音与样本语音，确定检材语音和样本语音是否源于同一讲话人的过程。现代讲话人司法识别研究的两大阵营分别是以法律语音学家为代表的语言学视角的识别研究和以电信工程师为代表的电子信息科学视角的识别研究。司法实践中的识别方法虽然纷繁多样，但都是这两大阵营研究成果的实际应用。司法实践现实条件复杂，而现实条件对识别实践影响巨大，现有识别研究中的实验材料脱离现实，加之缺少较一致的评价和验证标准，现有研究无法满足司法实践的迫切需要。录音设备的多样性与大众化、声音编辑软件的易操作性、声音资料所发挥的证据作用使越来越多的声音资料进入司法实践领域。司法语音识别研究的目的是对进入司法领域的声音材料进行鉴定，为刑侦和判案提供线索和证据。现有的研究主要包括语音同一认定、录音资料完整性检验、语音画像、模糊言语识别和噪音分析。对法律语言学研究者来说，机遇与挑战并存。研究希望能解决实验研究与司法实践脱节这一问题，为讲话人司法识别技术实践略尽绵力。
个人感悟
自入学以来精读了经典方法论及学术论文写作技巧书籍、文章；大量阅读法律语言学，尤其是司法语音识别的相关著作、文章，了解该领域的前沿动向。
对于想了解法律语音识别的朋友，P. Rose、A. P. A Broeders、F. Nalon、 G. S. Morrison、H. Hollien、王英利、杨俊杰、张翠玲等的著作、文章，可以帮助了解司法语音识别，尤其是讲话人识别的研究对象、研究方法、研究趋势等一些基本情况。
学海无涯，辛勤为桨，深厚的知识积淀、透彻的领悟力、敏锐的观察力和笃定的学术信仰是求知之舟永远不偏离航向的保证。
友情建议
对同行研究者及博士、硕士生的建议只有两点：
1. 注意方法，讲求效率,
2. 劳逸结合，适时减压。
Guan Xin，pursuing her doctoral degree in Foreign linguistics and applied linguistics, is interested in studies on Forensic linguistics. She has been working in Discourse analysis, Discourse Information Analysis and Forensic voice comparison.
FSR, the forensic application of speaker recognition, is the decision-making process during which one or more samples of an unknown voice will be compared with one or more samples of a known voice and then a decision whether they are matched or not has to be made. So far, forensic phoneticians and telecommunication engineers are the main researchers in this field, whose achievements have contributed to the diverse current FSR methods in practice. Forensic voice comparison is supposed to provide investigation and judgment some clues and evidence. Speaker recognition, authentification and integrity of recordings, speaker profiling, disputed utterance and audio analysis all fall in this category. Thanks to the popularization of diverse recording equipments and simple and non-technical voice-editing softwares, and the nature of accessibility, voice materials are playing more important roles in legal field and are absorbing more attention, which means there are a lot to do in this field for forensic linguistic researchers. Then come the key questions: what forensic linguistic researchers can handle and how to handle them as legal materials. However, there has been being a gap between ‘unrealistic test material’ in research and real voice materials involved in legal practice, and real-world conditions exercise ‘drastic effect’ on FSR (Rose, 1995; 1996; 2002), and evaluation and validation of different methods are absent ( Cambier-Langeveld, 2007). It seems apparent that the current FSR research and development could not properly fulfil the demands of legal practice. The intended research therefore aims at the current situation and attempts to bridge the gap and to make FSR research more applicable. To facilitate her research, she has studied statistics, read classical books and papers on methodology and academic writing in detail, and gone through books and papers on forensic linguistics, especially, those on forensic voice comparison, so as to have in mind the research trend and developing directions. The recommended literatures include books and papers by Rose, Broeders, Nalon, Morrison, Hollien, Wang Yingli, Yang Junjie, and Zhang Cuiling, etc, which are good resources of basic knowledge on forensic voice comparison, especially, FSR.
In order to gain knowledge and make contribution, hardworking is the companion and enough knowledge accumulation; thorough understanding, keen observation and firm academic faith are the premise.
