Abstract : Recognition of sounds created by rapid repetition, imitation, and phoneme discrimination of vowels is investigated. It is shown that the distinctness (with respect to phoneme classification) of sounds created by rapid repetition is dependent on the distinctness of initial sounds. Indistinct initial sounds also produce indistinct sounds at the output. The same effect is observed in imitation. In the case of phoneme discrimination indistinct initial sounds produce completely distinct sounds at the output. It is concluded that rapid repetition of sounds is coincident with their imitation. A two-stage scheme is considered for speech discrimination, based on preliminary imitation, and then on phoneme classification of the types of motions used in imitation. (Author)
