음성언어 처리 분야는 인간의 자연어 발화를 컴퓨터가 자동으로 이해하고 처리하는 알고리즘을 연구하는 분야로, 자동 통번역, Siri와 같은 음성 대화 시스템, 차세대 인터페이스, 질의 응답 시스템 등 다양한 응용군을 포함한다. 특히, 음성언어 처리 기술은, 최근 빅데이터(big data) 시대를 맞이하여, 방대한 음성/텍스트 정보를 처리하기 위한 필수 기술로 각광받고 있다. 한편, 빅데이터는 그 자체가 거대한 말뭉치 데이터로서 음성언어 처리 기술의 성능을 향상시키는 주된 리소스가 된다. 이에 따라, 최근 빅데이터를 이용하여 음성언어 처리 기술의 성능을 개선시키고자 하는 연구가 활발히 진행되고 있는데, 본고에서는 이들 연구의 배경 및 연구 동향들을 소개하기로 한다.
