An audiovisual speech synthesizer from unlimited French text is here presented. It uses a 3-D parametric model of the face. The facial model is controlled by eight parameters. Target values have been assigned to the parameters, for each French viseme, based upon measurements made on a human speaker. Parameter trajectories are modeled by means of dominance functions associated with each paramete...

Partition of unity parametrics (PUPs) are a recent framework designed for geometric modeling. We propose employing PUPs for procedural texture synthesis, taking advantage of the framework’s guarantees of high continuity and local support. Using PUPs to interpolate among data values distributed through the plane, the problem of texture synthesis can be approached from the perspective of point pl...

In this study a data-based approach to intonation modeling is presented. The model incorporates knowledge from intonation theories like the expected types of F 0 movements and syllable anchoring. The knowledge is integrated into the model using an appropriate approximation function for F 0 parametrization. The F 0 parameters that result from the parametrization are predicted from a set of featu...

One imagines composed music as originating in the mind of an author. Indeed, I have for the last five decades been composing music in this fashion. However, for the last four decades I have also been repeatedly attracted to various methods of deriving music from sources both inside and outside the field. These sources have been linguistic, acoustic (field recordings), visual and mathematical (p...

We propose a exible analysis/synthesis model for transient signals that eeectively extends the Spectral Modeling Synthesis (SMS) parameterization of signals from sinusoids+noise to sinu-soids+transients+noise. The explicit handling of transients provides a more realistic and robust signal model. The model presented is a parametric model for transients that allows for a wide range of signal tran...

A statistical parametric approach to speech synthesis based on hidden Markov models (HMMs) has grown in popularity over the last few years. In this approach, spectrum, excitation, and duration of speech are simultaneously modeled by context-dependent HMMs, and speech waveforms are generated from the HMMs themselves. Since December 2002, we have publicly released an open-source software toolkit ...

The problem of choosing the variable parameters a stabilizer an object which minimize additive quadratic integral functional reflecting complex requirements for closed stabilization system is considered. To solve combined method parametric synthesis stabilizer, sequential combination Sobol grid and Nelder-Mead method, proposed. At first stage by applying Sobolev working point in pace its transf...
