Listener’s Perception of Emotions in the Speech of Children with Hearing Impairment: Pre-post Prosodic Intervention
摘要
Expression of emotions is crucial for effective communication. Children with hearing impairment have difficulty perceiving and expressing different aspects of prosody, intonation patterns, word stress, and expression of vocal emotions. Understanding listener perceptions can enhance therapeutic practices and communication strategies for these children. The study aims to assess how well naive and experienced listeners can perceive emotions in speech samples of children with hearing impairment (HI) before and after prosodic intervention. Additionally, the study analysed the pre- and post prosody therapy differences on the accuracy of emotion identification. Ten listeners participated in the study: five naive listeners (Group I) and five experienced listeners from the field of speech language pathology (Group II). Speech sample of 120 sentences corresponding to five emotions, each of anger, happiness, sadness, surprise and fear were recorded from children with HI before and after 20 sessions of therapy focusing exclusively on prosodic training. The listeners were asked to identify the emotion conveyed in each sentence using a closed choice paradigm. Results revealed higher accuracy in emotion recognition post therapy, with better scores in experienced listeners compared to naive listeners, suggesting that professional training and experience play a crucial role in accurate emotional perception. Happiness was better recognized by participants of both the groups while there was difficulty in identifying the emotions of fear and surprise. The results emphasize the importance of prosody training for children with hearing impairment, in parallel with speech-language and auditory training. This combined approach helps to accurately perceive different emotions, thereby enhancing emotional expression and speech intelligibility of children with HI.
