辽宁方言在案件言语识别中的作用

随着科学技术的发展,不法分子利用手机、座机等现代通讯工具进行敲诈、勒索、绑架、恐吓、性骚扰、索贿等案件频发,同时也使被害人及公安机关获取视听资料成为可能。辽宁方言与普通话的差别主要表现在:平翘舌不分;将r声母读成y声母或l声母;将韵母为O]的读成e]韵母;把普通话里许多阳平调读成上声调。尤其是辽宁省管辖的市、县较多,分布较广,就使不同区域的辽宁方言又出现了各自的语音、词汇等特点。收集、调查、整理、运用辽宁及辽宁不同地区方言特点,就能在案件的言语识别时根据方音特点及方言词汇,准确判断犯罪嫌疑人的地域、年龄、职业、文化、性别等社会属性,为侦破工作提供方向和范围。
