Research

Audiovisual speech synthesis

1. Facial motion estimation from speech acoustics.
2. Speech acoustics estimation from facial motion.
3. 3D face scanning in order to build a parametric model of the human face.

Speech acoustics

1. Combining acoustic and morphological information for the estimation of the vocal tract shape from speech.
2. Acoustic measures of the vocal tract.
3. Using MRI in order to build a 3D parametric model of the vocal tract.

Speech production Modeling

1. Study of the relation between muscle activity and the movement of tongue, jaw and face.

Speech perception

1. Study of the relation between production and perception through spatial and temporal filtering of visible speech information.

Musical Instrument Sound Analysis, Synthesis and Classification

1. Modeling the dynamic spectral distribution of timbre using Principal Component Analysis (PCA) and Genetic Algorithms (GA).
2. Modeling the temporal timber variation based on Hidden Markov Models (HMM).

Independent Component Analysis (ICA)

1. Blind separation and deconvolution using ICA.

Functional Magnetic Resonance Imaging (fMRI) and Electroencephalography (EEG)

1. Trade off between temporal and spacial resolution in fMRI and EEG.

Wavelets

1. Wavelets with scale factor greater than two for a better frequency resolution.
