Abstract

Emotions can be expressed by all individuals. The speech conveys important information about a message and prosodic cues help in the understanding of what is being said. People with Down syndrome exhibit alterations in the global development, which implicate difficulties in language and communication. This study aims to analyze joyful and sad speech through acoustic analysis of the melodic contour of sentences spoken by people with and without Down syndrome. Data showed that people with Down syndrome exhibited differences in the melodic setting of at least one of the investigated emotions compared to people without the syndrome.
