Music feedback regulation system based on signal processing

Abstract

The invention discloses a music feedback regulation system based on signal processing. The music feedback regulation system comprises a music library, a music library unit, an emotion analysis unit, an emotion real-time monitoring unit and a music playing unit. The music library unit classifies music in the music library according to acoustic characteristics and lyric semantics of the music; the emotion analysis unit judges the initial emotion state of a subject according to audio characteristics; the emotion real-time monitoring unit monitors the emotion of the subject in real time through physiological signals and facial expression signals of the subject; and the music playing unit plays the corresponding music according to the initial emotion state and switches the music in real time according to the result of the emotion real-time monitoring unit. The music feedback regulation system based on signal processing achieves accurate matching of the music played by the subject based on accurate evaluation of the emotion state of the subject and accurate classification of the music, responds to changes of the body reaction mechanism of the subject, can automatically switch the played music, and has the self-learning and self-regulation functions, and the music switching function has the function of restraining emotion pseudo changes.

Description

technical field [0001] The invention relates to the field of artificial intelligence, in particular to a music playing system based on the emotional evaluation of speech and the feedback evaluation mechanism in response to the body reaction mechanism. Background technique [0002] Facing the rapidly changing society and the ever-accelerating pace of life, the pressure on the professional population is increasing day by day, and the phenomenon of mental sub-health is becoming more and more common. In response to this situation, in addition to relieving the patient's condition through drugs, there is also a physiotherapy mechanism through physiological effects-music physiotherapy, that is, by playing music for the patient in a quiet environment to relieve their physical and mental stress. Practice has proved that this method can act on the patient's neurons and relieve the patient's tension. [0003] However, although the current music therapy method has a relatively systemat...

Problems solved by technology

[0003]However, although the current music therapy method has a relatively systematic physiotherapy mechanism, it cannot provide patients with appropriate music accurately and pertinently. Determine the patient's emotional state by randomly playing music to observe the patient's emotional response, and then reassess the patient's state through this method after a predetermined interval, and achieve the effect of physical therapy through repeated iterations

This method first requires the patient to fully cooperate with the physical therapy process, and there will be multiple interruptions during the physical therapy process, which seriously affects the user experience; moreover, this method may also have the opposite effect, that is, the music that increases the patient's stress is selected for playback
