Speech intelligibility is an important outcome measure of speech therapy for people with orofacial cleft. Intelligibility assessment is most often carried out by experts. With the intention of evaluating therapy goals in real life, it is beneficial to add the assessment of naive listeners. Studying the difference between these assessments provides insight into the success of therapy, as well as into guidelines for new goals. All of the above is carried out with the intention of improving the quality of life of an individual with an orofacial cleft. The aim of this research is to examine whether there is a difference between naive listeners and speech-language pathologists in the assessment of speech intelligibility in children with orofacial clefts. Furthermore, the study investigated whether there is a correlation between the years of work experience of speech-language pathologists and the assessment of speech intelligibility. Five children with orofacial clefts between the ages of 5 and 7 participated in the research. The listening panel consisted of twenty speech-language pathologists (employed in different work places) and twenty naive listeners. Speech samples of children were collected through two tasks. The first one is a naming task in which phonological structure of the words varies from simple to more complex ones. The second task involves retelling the story according to the audiovisual presentation. The listening panel also had two tasks. In the first task participants needed to phonemically transcribe the words and write down their semantic variants. The second task consists of four short questions and a four-point rating scale for assessing intelligibility of spontaneous speech. The obtained results show that there is a statistically significant difference in the assessment of the speech of children with orofacial clefts between naive listeners and speech-language pathologists. Expert listeners assessed the speech as more comprehensible than the naive listeners did. However, no correlation was found between the years of work experience and the assessment of speech intelligibility. Speech-language pathologists with longer working experience did not evaluate speech as more intelligible than the ones with shorter working experience. This research aims to raise awareness of the importance of conducting such assessment. Also, it highlights the need to include everyday communication partners when it comes to assessing the speech intelligibility of the mentioned population, for the purpose of making a decision to end speech therapy.
