Alain's delay-subtraction model looks quite interesting and, indeed, may solve the problem of concurrent vowel segregation in an elegant fashion. It is, however, not intuitively clear to me how the model is going to estimate the vowel period when the vowels are not steady-state. If the model were true to life, it would do the job much more efficiently for the dynamically changing f0 (and f1 through f3???) case than for the steady-state case. If, however, it cannot deal with the problem, or deals with it with equal or lesser efficiency than with the steady-state vowels, then it would go down the drain, elegance notwithstanding.
