Title: Artificial Speech in Communications Research
Abstract: Artificial talkers and speech synthesis systems have long been used as a means of understanding both speech production and speech perception. This presentation will begin with an overview and history of artificial speech systems which includes mechanical models, electronic devices, and computation-based simulations. Our current work involves development of an airway modulation model (called "TubeTalker") that simulates the time-varying changes of the glottis and vocal tract, as well as acoustic wave propagation, during speech production. The result is a certain type of artificial talker that can be used to study various aspects of how sound is generated by humans and how that sound is perceived by a listener. The primary components of the model will be demonstrated with animations and sound samples.
