Connecting without Reaching: How Voice-cloned Robot Can Enhance Mental Health of Isolated People During a Pandemic

Voice cloning techniques using deep neural networks have been used for frauds, such as false financial transactions or fake news, limiting their widespread application. However, when incorporated with communication robots, voice cloning may increase social connectedness for isolated people. Herein, we suggested the concept of a voice-cloned communication robot (VCR), equipped with acquaintances' voices to allow people in isolation to feel connected with their acquaintances. We developed a prototype VCR, conducted exploratory qualitative and quantitative studies, and verified its potential effectiveness in enhancing the mental health of isolated people.
