SightSinger uses AI Voices, also known as voicebanks, created by independent creators and communities. We respect their work and only make AI Voices available where the licence or creator permission allows our use case.
An AI Voice or voicebank may include singing voice models, model files, configuration files, dictionaries, phoneme lists, character names, character designs, images, documentation, licence terms, and other related materials.
SightSinger users do not receive direct access to the underlying AI Voice, voicebank, or model files. Users interact with the AI Voice through SightSinger and receive generated audio.
This page explains which AI Voices are currently available, what attribution may be required, and where to find the original AI Voice or voicebank terms.
