Abstract
Employing social robots in interactions with children for educational and healthcare objectives could enhance the efficiency of interventions and boost the children’s cognitive and affective outcomes by increasing engagement and providing motivation. This dissertation investigates three main subtopics to determine the efficacy of utilizing social robots in speech therapy sessions in interactions with children suffering from speech and language disorders. We hypothesize that interacting with social robots acting as therapists’ assistants in speech therapy interventions contributes to the formation of language-based communications and improves the individuals’ language skills. The first...

Abstract
The ability to speak lucidly plays a key role in social relations. Consequently, the role of the larynx is quite important, and timely diagnosis of laryngeal diseases has proved to be crucial. In this study, a simple computational model for inverse of speech production model is employed to extract the glottal waveform using speech signal. This waveform has useful information about vocal folds performance in terms of providing evidence for distinguishing pathological disorders. Furthermore, obtaining the significance of classification results is important, because it leads to reliable inferences. This study utilizes the sustained vowel sound /a/ and a well-referenced database, namely MEEI. In...
