DUPLEX PERCEPTION
A phenomenon that occurs when the phonetic features of a synthetic stimulus are split into two and part is presented to each ear.
Experimenters have found that part of the third (highest frequency) formant is critical to the distinction between /da/ and /ga/. When this section is excised, the remainder (or ‘base’) is heard by the listener as intermediate between the two syllables. If the base is played to one ear and the distinctive section of the third formant to the other, subjects report hearing the whole syllable (/da/or/ga/) in the first ear and a non-speech chirp in the second. It seems that the speech perception mechanism groups acoustic elements together even when they are derived from different sources.
There is interest in duplex perception because it violates a principle which states that an acoustic category cannot be assigned to more than one sound source. This provides support for a view that there is a special speech mode: i.e. that speech and non-speech sounds are processed differently.
