Speech outcomes after a palatoplasty is not sufficiently researched in Croatia. Nasality is the main characteristic of speech of children born with a cleft palate which very often remains present in speech even after surgical correction.To assess the effects that cleft palate has on speech the most important is a subjective assessment of speech. The aim of this research is to subjectively evaluate and describe in detail nasality and speech intelligibility in six preschool children born with cleft palate, as a form of six case studies. A speech sample of 6 preeschool children born with soft and/or hard cleft palate was collected. The age range is from 4,2 to 6,2 years. The recorded speech sample contains isolated words and sentences saturated with plosives and fricatives and doesn't contain nasal sounds. The assessment was conducted in a Laboratory for hearing and speech acoustics in the Faculty of Education and Rehabilitation Sciences, University of Zagreb. Assessors were speech and language pathology (SLP) students. Each word and sentence was listened twice, after which the students first evaluated nasality, and then comprehensibility by comparing the answers to the questionnaire according to the offered scale of numbers from one to five, one indicating the greatest nasality and incomprehensible speech, and the number five indicating comprehensible speech without nasality. All collected data, anamnestic as well as evaluation results are descriptively presented. The first premise that children's speech will be more nasal and less understandable in the production of sentences is confirmed in four out of six respondents. The second hypothesis was partially confirmed because the speech of the child with the clef of hard and soft palate was evaluated as the most nasal, while the speech of the child with the only soft palate cleft was evaluated as the least nasal. The third premise has also been partially confirmed. The highest scores on the speech intelligibility variable were obtained by children who were included in the early intervention program and were later monitored or included in the direct form of therapy. This case series study opens up space for further thorough research that will provide an answer to the degree of speech nasalance in preschool children as well as outcomes in other speech and voice parameter.
