Asthma Detection Research Based on Voice Signal Processing and Machine Learning.

To analyze voice signals and identify asthma patients using voice signal analysis and machine learning techniques, we collected clear, low-noise fixed-pattern voice signals from 50 asthma patients and 50 healthy controls to build an analysis database. The research conducted multi-dimensional voice signal analysis based on MATLAB and selected voice feature indicators with significant differences between asthma patients and healthy controls. After dimensionality reduction analysis on differential phonetic features, the processed features were incorporated into subsequent SVM and RF modeling and classification research.
