摘要：Voice analysis for disease detection is a very important research topic in bio medical engineering. This process is non invasiveand reliable. In this paper , For comparison of asthma and healthy persons speech records of five vowels /a/, /i/, /e/, /o/, /u/ have been used.Some acoustic voice parameters jitter, shimmer, harmonic to noise ratio (HNR), noise to harmonic ratio (NHR) & mean autocoorelationwere extracted using PRAAT software. These parameters were then used to classify and compare the asthmatic patients and healthypersons. In other words, these features represents the particular voice and may be used for the comparison of healthy persons fromunhealthy persons. This result suggests that the feasibility of the detection of asthma disease through analyzing the various acousticparameters of voice
