Assessment of heart rate variability from speech analysis

This work shows the behavioral and heart condition monitoring of the patients during the COVID-19 infection. As the COVID-19 infection spreads very easily through contact, this work introduces a noninvasive technique to monitor such patients. The heart condition monitoring can be done through the analysis of acousticalcardiogram (ACG) as well as the behavioral changes observed through the Formant analysis. The speech of the patient is recorded, digitized, and its analysis is done using the PRAAT software. The required information from the speech samples is extracted and subjected to the analysis. The spectrogram of each utterance is plotted, and its first and second formants are analysed to form the vowel triangle. These vowel triangle provides behavioral monitoring. The monitoring of heart condition can be done using ACG. The Formant analysis of utterance of 12 Hindi consonants provides the assessment technique of the patient heart condition.
