HEART RATE MEASUREMENT FROM VOICE SIGNAL USING COMPLEX WAVELET ANALYSIS
It is well known that the heart rate is most important diagnosis parameter of human nervous and cardiovascular systems. Traditionally, measurement of this value related to the set of contact methods such as ECG processing, phonocardiography, pulse detection. This paper presents a novel non-contact heart rate extraction method from vo wel speech signals. The complex wavelet analysis has been used to establish relationship between speech production of vowel speech signals and heart activities for humans.
