Prosodic timing analysis for articulatory re-synthesis using a bank of resonators with an adaptive oscillator

A method for the analysis of prosodic-level temporal structure is introduced. The method is based on measured phase angles of an oscillator as that oscillator is made to synchronize with reference points in a signal. Reference points are the predicted peaks of acoustic change as determined by the output of a bank of tuned resonators. A framework for articulatory resynthesis is then described. Jaw movements of a robotic vocal tract are made to replicate the mean phase portrait of an utterance with reference to a production oscillator. These jaw movements are modeled to inform the dynamics of withinsyllable phonemic articulations.
