The present invention relates to an automatic multimedia speech recognition evaluation system using a speech synthesis engine, and more particularly, to an automatic multimedia speech recognition evaluation system using a speech synthesis engine, which uses a TTS engine (speech synthesis engine) to play and evaluate new sentence patterns in real time without recording in order to improve the problems, of an existing automatic speech recognition evaluation system which sequentially plays pre-recorded speech data to evaluate the recognition rate of a speech recognition apparatus, such as enormous time and cost due to the continuous construction of a speech recording DB and the possibility of not recognizing other sentences with the same meaning, thereby outputting accurate and fast performance and functional verification results. The automatic multimedia speech recognition evaluation system according to the present invention comprises: an automatic speech recognition test device (100); a TTS driving device (200); and a speech recognition engine device (300). 본 발명은 음성합성엔진을 이용한 멀티미디어 음성인식 자동 평가시스템에 관한 것으로서, 더욱 상세하게는 미리 녹음된 음성 데이터를 순차적으로 재생하여 음성 인식 장치의 인식률을 평가하는 일반적인 음성인식 자동 평가시스템의 음성녹음DB의 지속적인 구축에 따른 막대한 시간과 비용 소요, 같은 의미의 다른 문장을 인식하지 못할 가능성 등의 문제점을 개선하고자 TTS엔진(음성합성엔진)을 활용하여 언제든지 새로운 문형을 녹음없이 실시간으로 재생하여 평가할 수 있는 음성인식 자동 평가시스템을 제공함으로써, 정확하고 빠른 성능과 기능 검증 결과를 출력할 수 있는 음성합성엔진을 이용한 멀티미디어 음성인식 자동 평가시스템에 관한 것이다.
