The Validation of Speech Recognition Performance Change according to the kind and established distance of the Microphone

마이크로폰의 종류 및 설치거리에 따른 음성인식성능변화의 검토

Speech recognition performance depends on various factors. One of the factors is the characteristic and established distance of a microphone which is used when speech data is collected. Thus, in the present experiment speech databases for tests are created through the type and established distance of a microphone. Then, acoustic models are built based on these databases, and each of the acoustic models is assessed by the data to determine recognition performance depending on various microphones and established microphone distances.
