JUSTIN sings: adding a musical-style narration generator to an APGWAP that collects ukiyo-e artworks descriptions

This study improves JUSTIN (Japanese Ukiyo-e Streaming That Improves Narrative), an audience participation game with a purpose (APGWAP) designed for promoting ukiyo-e artworks and collecting descriptions about them from a group of people over a game live streaming platform, by adding a musical-style TTS that narrates the best description made by the player for each image in each round. It is expected that narrating the best descriptions for each image will make the winner feel more rewarded and encouraged to make better descriptions in the upcoming rounds. The narration is provided to players in a musical fashion considering evidences that music has several therapeutic benefits, including stress relief and mental health promotion.
