A phonetic analysis and comparison of nineteen consonant sounds as they appear in the speech of normal hearing and hard of hearing children

The objectives of this study were to compare the speech patterns of normal hearing and hard-of-hearing children in order to further describe the relationship of these two groups; to survey the literature to determine group comparisons already established; to provide statements which would further clarify the relationship; and to report these statements for use in the field of speech and hearing pathology. A total of one hundred thirty-four subjects were used in the study. An audio gram and speech analysis were secured on each subject. Subjects were then divided into five groups: Normal hearing; slight hard-of-hearing; moderate hard-of-hearing; educationally deaf; and profoundly deaf. Sound graphs were formed which revealed the percentage of subjects in each group having a given sound defective. These sound graphs were grouped according to site of placement and manner of formation.
