The construction method of the VEM-Token vocal emotion multi-modal magic modification model is different from the natural language processing model NLP-Token which interprets music through text. Instead, the VEM-Token sound-to-text innovation model comes with vocal emotion multi-modal information. The model captures and aligns the music tempo of sample songs and user learning songs, identifies various modalities of vocal emotion, divides the file into word units based on tempo, obtains VEM parameters through supervised learning and reinforcement learning, and decomposes songs into vocals, accompaniment, and emotion. The magic modification model provides a multi-modal magic modification method for imitating sample songs, including vocals, accompaniment, emotion overtones, emotion fluctuations, learning to sing, voice cloning, lyrics, pitch calibration, ornaments, tempo length, rhythm speed, tempo strength, freedom, and multiple sample magic modification. It also provides member management, mobile and PC application systems, dedicated support hardware, and communication protocols including MIDI, making it easy to access popular AI large models, reducing model hallucinations, and forming AI vocal agents and AI karaoke.
