A method and apparatus for detecting counter homeostasis oscillation perturbation signals (CHOPS) found within the wave form of human speech that reflects either arousal in the autonomic nervous system or other biological processes. The apparatus is a speech analysis system for obtaining biofeedback information from human speech samples having variable duration. The speech analysis system comprises means for digitizing the human speech samples, storage means for receiving the digitized speech samples from the digitizing means and storing the digitized speech samples, processing means for detecting and analyzing CHOPS in the digitized speech samples and display means for presenting the analyzed speech samples in a visual representation. The speech analysis system may further include transducer means for collecting and transducing human speech samples into electrical signals and input means for configuring the analysis parameters of the processing means. The present invention does not require any electrode or probe attachment from the speech analysis system to a subject. The method provides biofeedback from physiological indicators of stress using the speech analysis system. The method includes recording a human speech sample having variable duration with the transducer means, digitizing the human speech sample with the means for digitizing, storing the digitized speech sample in the storage means, determining CHOPS in the digitized speech sample with the processing means based on pre-determined parameters and identifying relationships between the CHOPS in the digitized speech sample with the processing means.
