Re: Phoneme versus word recognition.

[Brent Edwards <brent@xxxxxxxxxxx>]

Boothroyd and Nittrouer ("Mathematical treatment of context effects in
phoneme and word recognition," J Acoust Soc Am. 1988 Jul;84(1):101-14)
looked at CVC word recognition as a function of recognition of the
individual phonemes. He found for *nonsense* CVCs that the probabilities of
recognizing the word  (p_word) and for recognizing the phonemes (p_phoneme)
are related as follows:

p_word=(p_phoneme)^3

indicating that the phonemes are independent components. For *meaningful*
CVCs,

p_word=(p_phoneme)^2.5

indicating the superiority of identifying each phoneme when they are grouped
together in a meaningful word. Is this what you are looking for?
