The Kanto Karaoke TV App brings professional-grade karaoke to Smart TVs with seamless mobile integration. This development project centers on creating a native TV application that offers voice tone adjustments tailored to the user's detected voice type (such as soprano, mezzo, alto, and others), accompanying guide vocals matched to the singer's profile, precise real-time scoring for performances, and dynamic user rankings per song at country and global levels. Kanto's TV app facilitates effortless synchronization with the native mobile app for remote control and interaction, adaptive high-quality video streaming to ensure smooth playback, and a collaborative song queue system allowing all connected users to add tracks. Real-time social features enable the exchange of stickers and messages from mobile devices, creating a lively, multi-user environment. The integration of advanced audio processing, cross-device connectivity, and community-driven tools results in a robust platform that elevates casual singing into engaging, competitive, and shared sessions for friends and families.
