The periodic opening and closing of the vibrating vocal folds changes the production system continuously during the production of voiced speech. The subglottal and supraglottal cavities have distinct structure and impedance. A coupling and decoupling of these cavities affects effective length of the…
For voiced speech, significant excitation of the vocal tract system is due to sequence of impulse-like events in the vocal fold vibration. Significant excitations take place around the instants of glottal closure (GCIs), which are often referred as epochs. In literature, most of the epoch extraction…
This paper investigates the application of unsupervised acoustic unit discovery for topic identification (topic ID) of spoken audio documents. The acoustic unit discovery method is based on a non-parametric Bayesian phone-loop model that segments a speech utterance into phone-like categories. The di…
