This paper reviews 1) variations of room acoustic transfer functions due to the change of room temperature and 2) the compensation method using a time axis scaling method. It is shown that a slight change of room temperature is a dominant factor for the variations of room impulse response. It is also shown that the compensation method applied to an inverse filtering-based dereverberation approach improves the intelligibility and speech recognition rates dramatically.
