In this paper, we present a method for synthesizing photorealistic visual speech using a parametric model based on quadtree splines. In an image-based visual speech synthesis system, visemes are used for generating an arbitrary new image sequence. The images between visemes are usually synthesized using a certain mapping. Such a mapping can be characterized by motion parameters estimated from t...

The problem of fault detection and isolation of parametric faults is considered in this paper. A fault detection problem based on parametric faults are associated with internal parameter variations in the dynamical system. A fault detection and isolation method for parametric faults is formulated in a standard setup and a synthesis method for the fault detector is given. Further, fault detectio...

Traditionally, human texture perception has been studied using artificial textures made of random-dot patterns or abstract structured elements. At the same time, computer algorithms for the synthesis of natural textures have improved dramatically. The current study seeks to unify these two fields of research through a psychophysical assessment of a particular computational model, thus providing...

This paper is an initial investigation into using knowledge-based parameters in the field of statistical parametric speech synthesis (SPSS). Utilizing the types of speech parameters used in the Klatt Formant Synthesizer we present automatic techniques for deriving such parameters from a speech database and building a statistical parametric speech synthesizer from these derived parameters. Altho...

This paper describes the implementation of a new parametric model of the glottal geometry aimed at improving male and female speech synthesis in the framework of articulatory analysis synthesis. The model represents glottal geometry in terms of inlet and outlet area waveforms and is controlled by parameters that are tightly coupled to physiology, such as vocal fold abduction. It is embedded in ...

Just recently Flank Milling has opened up new possibilities in detailing large-scale architectural building envelopes. Whereas examples such as the Hungerburgbahn by Zaha Hadid show the application of Flank Milling at the end of the architectural manufacturing process, our research, in contrast, focuses on the implementation of constraints immanent to manufacturing techniques as early architect...

This paper compares di erent methods of generating intonation for an American English Text-to-Speech synthesis system. We look at a primarily rule-based approach and two data-driven approaches. For data-driven modeling we used two separate data sets, each representing a somewhat di erent prosodic style. One database was recordings of a portion of 1989 Wall Street Journal text from the Penn Tree...

This paper introduces a novel model-constrained, data-driven method for generating fundamental frequency contours in Japanese text-to-speech synthesis. In the training phase, the parameters of a command-response F0 contour generation model are learned by a prediction module, which can be a neural network or a set of binary regression trees. The input features consist of linguistic information r...

An all-digital on-chip delay measurement (OCDM) architecture with high delay measurement resolution and low supply voltage sensitivity for efficiently detection and diagnosis in the high performance system-on-chip (SoC) applications is presented. Based on the proposed differential delay line pair (DDLP) and an cascadestage delay line, the quantization resolution of the proposed OCDM not only ha...

It is known that voice quality plays an important role in expressive speech. In this paper, we present a methodology for modifying vocal effort level, which can be applied by text-to-speech (TTS) systems to provide the flexibility needed to improve the naturalness of synthesized speech. This extends previous work using low order Linear Prediction Coefficients (LPC) where the flexibility was con...
