この能力とは何か
Takes a text description, optionally with lyrics or a style reference, and outputs audio — a full song, an ambient bed or a sound effect. It must handle melody, harmony, arrangement and timbre at once, adding a layer of musical structure on top of speech synthesis. Unlike text-to-speech the output is not language but rhythmically and tonally organised audio.
技術的にどう実現するか
The mainstream uses an audio latent representation with diffusion or autoregressive generation: audio is first compressed into discrete or continuous tokens, generated under conditioning, and decoded back to a waveform. Structural tags during training teach the model the order of intro, verse and chorus. Lyrics and vocals are produced by separate alignment and synthesis modules and then mixed with the accompaniment into a finished track.
