Abstract
The vocal tract acts like a series of band-pass filters, one for each resonance. [...]a spectrum of frequencies from the source (the glottal airflow) is filtered by the vocal tract to produce the output at the mouth. Investigators generally resort to a technique known as inverse filtering, basically undoing what the vocal tract does as a filter.1 Either the acoustic pressure radiated from the mouth or the acoustic flow at the mouth can be inverse filtered to obtain an estimate of the glottal airflow wave shape.2 Figure lb shows an example of an original glottal wave shape and an inverse filtered wave shape obtained from the radiated pressure in Figure la. Anil Palaparthi received his BE degree in electronics and communications engineering from the Andhra University, Visakhapatnam, India, In 2007, and the MS degree in electrical and computer engineering from the University of Utah, Salt Lake City, in 2009.
