The American Community Survey revealed that 21.3% of individuals living in the United States speak a language other than English at home, being Spanish as the second most spoken language. Phonological disorders in children affect approximately 10% of the pediatric population; 80% of these children are diagnosed as severely delayed. The early clinical treatment of phonological disorders by SLPs is key to remediate deficits in the phonological repertoire and awareness of children and avoid potential difficulties in other areas of development areas such as reading, writing, spelling, and mathematical abilities. This investigation evaluated whether the use of minimal pairs or maximal pairs would bring greater improvement to the production of targeted phonemes in children aged 3:0 to 6:11 years.
