Abstract (in Japanese) (See Japanese page) 
(in English) In order to improve speech intelligibility in reverberation, steady-state suppression was proposed by Arai et al. [Proc. Autumn Meet. Acoust. Soc. Jpn., 2001; Acoust. Sci. Tech., 2002]. On the other hand, a consonant enhancement technique for real-time processing in noise was proposed by Yasutake et al. [Tech. Rep. of IEICE Japan, 2005]. Our ultimate goal is to implement steady-state suppression in real-time. We discussed whether these two techniques are treated within a single unified framework because suppressing energy in vowels essentially enhancing consonants. As a result, we confirmed that the consonant detection method used in Yasutake et al. was included in steady-state suppression for real-time processing.
