Word Intelligibility in Multi-voice Singing: The Influence of Chorus Size

Using Contextual and Visual Cues to Improve Sung Word Recognition in Hearing Aid Users

Older adults commonly experience hearing loss that negatively affects the quality of life and creates barriers to effective therapeutic interactions as well as music listening. Music therapists have the potential to address some needs of older adults, but the effectiveness of music interventions is dependent on the perception of spoken and musical stimuli. Nonauditory information, such as contextual (e.g., keywords, picture related to song) and visual cues (e.g., clear view of singer's face), can improve speech perception. The purpose of this study was to examine the benefit of contextual and visual cues on sung word recognition in the presence of guitar accompaniment. The researcher tested 24 community-dwelling older adult hearing aid (HA) users recruited through a university HA clinic and laboratory under 3 study conditions: (a) auditory stimuli only, (b) auditory stimuli with contextual cues, and (c) auditory stimuli with visual cues. Both visual and contextual nonauditory cues benefited participants on sung word recognition. Participants' music background and training were predictive of success without nonauditory cues, and visual cues provided greater benefit than contextual cues. Based on the results of this study, it is recommended that music therapists increase the accessibility of music interventions reliant upon lyric recognition through the incorporation of clear visual and contextual cues.
