Preliminary Experiments on the Perception of Double Semivowels

A number of previous studies have shown that it is possible to recognise two vowel sounds spoken simultaneously if their pitches, onsets or the spatial locations of their sources differ sufficiently. Experiments have been carried out to explore the perception of isolated syllables containing the glides /w/ and /j/ spoken at the same time. It was found that consonants in concurrent syllables which contained the same vowel but were spoken with different pitches could not be reliably identified. However if the vowels and their pitches differed, the glides could be recognised about 70% of the time. This suggests that the neuronal mechanisms underlying the separation of simultaneous consonants employ other features as well as pitch differences
