Abstract
Eight sets of phrases were constructed for oral reading. Two sets were comprised of five syllables, in one instance consonant-vowel syllables and in the other, vowel-consonant. Three sets were made to include only syllables of two, three, or four sounds and a total of either 15 or 16 sounds. Three additional sets were the same as the preceding ones except that the total number of sounds was either 20 or 21.
Each group of twenty-four young male adults read a set of the phrases under 12 conditions of delayed side-tone ranging from zero delay to 0.30 sec. delay. The duration of the oral phrase was measured.
The reading of phrases of vowel-consonant syllables was more adversely affected by delayed side-tone than was the reading of consonant-vowel syllables, and the disparity between the two increased as the amount of delay of side-tone was increased to 0.21 sec. Otherwise syllables and phrases of different lengths were responded to “alike,” there being no interaction between the amount of delay of side-tone and the structure of the phrase.
