Automated lip-sync animation as a telecommunications aid for the hearing impaired (2008)
David Mcallister, Robert Rodman, Donald Bitzer, Andrew Freeman
Vocal communication is most effective when the listener is able to observe the mouth of the speaker. This is especially true for the hearing impaired, and dramatically true for the deaf, who rely on...
An Algorithm for V/UV/S Segmentation of Speech by (2008)
Meng Wang, Donald Bitzer, David Mcallister, Robert Rodman, Jamie Taylor
Let f(n) be a sampled voice signal. Our goal is to identify the voiced (V) portions of f (as opposed to the silence (S) and unvoiced (UV) portions). In the following discussion, the sampling rate is...
This paper describes a method to construct predictor surfaces for mouth parameters, using Delaunay triangulation. The first and second moments of the input speech signal are mapped to the shape of...
Predictor Surfaces for Lip Synchronization Animation of Voiced Input (2008)
Rika Krothapalli, David F. Mcallister, Robert D. Rodman, Donald Bitzer, Meng Wang, Jamie Taylor
The authors are producing two-dimensional animated human faces with lip motion synchronized to a given speech sound file. The process is called lip synchronization. We assume the only input is the...
Speaker Independence in Lip Synchronization of Vowels (2008)
Jamie Taylor, Donald Bitzer, Robert Rodman, David Mcallister, Meng Wang
This paper presents a method for achieving speaker independence in the lip synchronization of vowels by performing an affine transformation on the moments of the spectrum of the speech. A speech...

Tiffany Barnes, Donald Bitzer, Mladen Vouk
Abstract. The q-matrix method, a new method for data mining and knowledge discovery, is compared with factor analysis and cluster analysis in analyzing fourteen experimental data sets. This method...
A mechanistic model for +1 frameshifts in eubacteria (2007)
Ponnala, Lalit, Bitzer, Donald, Stomp, Anne, Vouk, Mladen
This work applies the methods of signal processing and the concepts of control system design to model the maintenance and modulation of reading frame in the process of protein synthesis. The model...
Predicting Shine-Dalgarno sequence locations exposes genome annotation errors (2006)
Joshua Starmer, Anne Stomp, Mladen Vouk, Donald Bitzer
In prokaryotes, Shine-Dalgarno (SD) sequences, nucleotides upstream from start codons on messenger RNAs (mRNAs) that are complementary to ribosomal RNA (rRNA), facilitate the initiation of protein...
