Conclusion
To be sure, a lot more is to be learned about dichotic fusion and auditory segregation in speech stimuli. While fusion clearly takes place in duplex perception, we do not know at what level in the auditory system it occurs, what kinds of neural mechanisms it involves, and whether or not it is specific to phonetic perception. These interesting questions should be pursued without further distraction.
