Speech Intelligibility for Interaural Alternated Speech With and Without Intervening Noise for Words and Nonsense

Speech discrimination for nine sophisticated listeners was examined for the effect of interaural alternation of both word and nonsense syllable test materials in the presence and absence of intervening noise. No degradation of speech discrimination was noted for words without intervening noise; however, there was some effect for speech discrimination of nonsense syllable test materials. When intervening noise was employed, difficulty in speech discrimination was noted for both the word and nonsense syllable test materials.
