Singo is a mobile singing assistant designed to help users sing more comfortably by personalizing songs to match their vocal range. The app allows users to adjust the key of a song and analyzes their performance after singing. Using advanced audio processing techniques, Singo compares the user’s voice with the modified melody, detects off-key or missed notes, and provides a percentage-based pitch accuracy score. Through personalized insights and easy-to-understand feedback, Singo encourages users to enhance their vocal skills, build confidence, and enjoy singing as both a fun and expressive experience.
