摘要：
The present invention relates to a time delay estimation device. The time delay estimation device of the present invention includes a sound signal detection unit configured to detect sound signals through a plurality of microphones, a frequency domain conversion unit configured to convert the detected sound signals into signals of a frequency domain, and a time delay estimation unit configured to estimate a time delay on the basis of a slope of a phase difference between the sound signals converted into the frequency domain.
