Inter- and intra-speaker variability of glottal flow derivative using the LF model

The vowels /a, i, u/ spoken by American English talkers with non-pathological voices are described by means of voice source model parameters using the Liljencrants-Fant (LF) model. The sampling frequency of the data is 8 kHz which matches approximately telephone bandwidth. After inverse filtering, trends of voice source characteristics depending on the LF parameters are analyzed and compared to literature and listening results.
