Toward the Development of a Dysarthria Diagnostic System in Telemedicine
Assistant Professor Yuya Hosoda of the Center for IT-Based Education (CITE), Toyohashi University of Technology developed a method for estimating the pitch of vocal cord vibrations of humans from call audio. In this method, the pitch is estimated by integrating the feature quantities extracted from the amplitude and phase spectra of speech on the complex plane. Through experiments, we have demonstrated that the proposed method is not only efficient for call audios whose frequency band is restricted by communication standards, but also works robustly in an environment with background noise.
