Abstract	In a noisy environment cellular phone users often have difficulties in hearing far-end speech because the ambient noise disturbs the user’s understanding of the conversation. To improve speech intelligibility in noise, speech enhancement is a feasible solution. In this paper the effects of two speech enhancement methods, multiband amplitude compression and formant enhancement, are reported. The multiband amplitude compression is a typical method for hearing aids that divides speech signal into some frequency bands and conducts amplitude compression independently. On the other hand, the formant enhancement is an LPC analysis-synthesis technique that provides for formant frequency shaping. The performances of these methods on the speech intelligibility were evaluated in the simulated real-world noise circumstances. Recorded noise sounds were presented from loudspeakers in a soundproof room and the speech samples were reproduced from real cellular phone handset which was fixed on the subject’s head. VCV !vowel–consonant–vowel sequence" units were used as test speech samples. The results show that multiband amplitude compression makes significant improvement in speech intelligibility and does not degrade the subjective impression of speech. 3aEAb6.
