Syllable segregation occurs within a word when the movement from one syllable to another is disrupted and so speech will sound halting, dysfluent or staccato
I would look into the work of Dr. Peter Assman at the University of Texas at Dallas (my old alma mater). Thomas Powell at Louisiana State has also been doing work in clinical phonetics and speech perception. He also has an account here, so you might want to reach out to him.
