Circuit Design and Simulation Based on Speech Emotion Recognition Method

The use of voice feature elements to automatically recognize people's emotional state has become a research hotspot of smart medical care. Based on the principle of MCU technology and speech acoustics,this paper analyzes the characteristics of speech rate,amplitude and fundamental frequency,and designs a speech emotion recognition circuit for bipolar disorder. The circuit includes six core modules,such as signal acquisition,threshold comparison and counting calculation,which realizes the effective capture, analysis and two-class discrimination of the emotional state of the speech signal. By using actual speech samples and signal simula-tion,the simulation of the circuit is carried out by Multisim software,which proves the effectiveness and correctness of the circuit. The circuit design is compact,has good pertinence and verification,and has certain teaching value.
