Optimization of multimedia computer-aided interaction system of vocal music teaching based on voice recognition

Based on the computer-aided system structure and combining the characteristics of the music sight-singing subject in the teaching content and teaching methods, this paper studies the vocal music teaching system model of sound recognition and completes the design of the overall system architecture, combining music sight-singing. The characteristics of the subject in the music teaching system provided a theoretical basis and reference for the realization of the system. It formed a complete and feasible enhanced string instrument and computer interactive electronic music system framework to meet the teaching needs of experimental interactive electronic music creation and performance. A set of scoring difficult feature sets with good discrimination is proposed, and a score recommendation algorithm and strategy based on score difficulty is designed to realize the personalized push of learning resources in intelligent tutoring. We put forward a method and model for evaluating the level of music sight-singing ability with certain applicability. Degree defines multiple ability evaluation indicators to realize the intelligent evaluation of the learner's cognitive level in the intelligent guidance system. This study provides a solid foundation for further research in the future. © 2021 CAD Solutions, LLC.
