摘要：
A system and method to assess vocal function of a subject. The system includes an accelerometer configured to acquire surface acceleration data associated with vocal functionality of the subject and a computer system configured to analyze the surface acceleration data and to estimate glottal airflow wave-forms produced by the subject based on the surface acceleration data. The computer system performs the analysis and estimation by applying an inverse filter to the surface acceleration data based on a calibrated transmission line model and generates an indication of vocal functionality of the subject based on the estimated glottal airflow waveforms.
