An automated method for matching a vocal fold contact area model to an EGG waveform
Ingo R. Titze, Haixiang Liang · The Journal of the Acoustical Society of America · 1990
Electroglottography (EGG) signals arc routinely used for observation of vocal fold adduction and regularity in vocal fold vibration. Analysis over many cycles can be very tedious if waveform parameters arc extracted manually or semiautomatically. A parameter optimization strategy is used here to provide a list fit to a model, thereby allowing larger volumes of data to be processed. Processing speed and reliability of extraction depend on the type of model being used and the cleverness in choosing the appropriate seed values. [Work supported by NIH.]
