  • Abstract
  • Look Inside

 The articulation of speech sounds was tested on 218 children from 25 nursery schools, ages ranging from 3 to 5. Picturecard articulation test was so designed to represent 66 different speech sounds. About one year after the first test, a retest was made on the identical group to compare the results of these two tests.

 About 70 percent of the erroneous sounds made in the initial test was found to be improved at the time of the retest. There was no significant difference in the rate of improvement among the different age-groups. Some of the common types of errors were pronouncing 〔tʃ〕instead of 〔ts〕, 〔dʒ〕 or 〔d〕 instead of 〔dz〕, and 〔tʃ〕 or 〔ʃ〕 instead of 〔s〕. The type oferrors that made the biggest improvement was that of plosive-plosive substitution while that of the least improvement was seen in fricative-fricative substitution. It was also observed that some syllables when arranged in different combinations were articulated differently, a fact which suggests that a great care and scrutiny must be made in selection of test words.
