Abstract
The effects of small room reverberation (T = 0.8 s) on phoneme recognition was studied for normal human listeners. Recognition performance was significantly poorer under reverberation than in quiet, and poorer in the final position of words than initially. Relative information transmission under reverberation was poorest for place of articulation and for stop and frication consonants, whereas sibilance, duration and semivowel information were barely affected. Apparently small room reverberation affects phoneme recognition in much the same way as a speech-shaped masking noise. In some cases, the error distributions reflect the limited response alternatives imposed by the real word recognition test.
