Speech transcription for Embodied Conversational Agent animation
This article investigates speech transcription within a framework of Embodied Conversational Agent (ECA) animation by voice. The idea is to detect some pronounced expressions/keywords in order to animate automatically the face and the body of an avatar. Extensibility, speed and precision are the main constraints of this interactive application. So after defining the set of […]

Growth of Amorphous Ti–Si–O Thin Films by Aerosol CVD Process at Atmospheric Pressure
We present the deposition of amorphous thin films by an aerosol chemical vapor deposition process at atmospheric pressure. We used di-acetoxi–di-butoxisilane, tetrabutoxysilane, and titanium(IV) -butoxide as precursors, and the deposition temperatures ranged from 475 to 675°C. During the deposition process a chemical reaction between the different precursors took place. We found a synergetic mutual influence […]

Density, thickness and composition measurements of TiO2–SiO2 thin films by coupling X-ray reflectometry, ellipsometry and electron probe microanalysis-X
Mixed TiO2–SiO2 thin films were deposited by aerosol atmospheric CVD method by using di-acetoxi di-butoxi silane (DADBS) and Ti tetrabutoxide as precursors. By varying the deposition temperatures between 470 and 600 8C and the ratios between the Si and Ti precursors (Si/Ti) from 2 up to 16, films with different compositions and thicknesses were deposited. […]

Reconnaissance audiovisuelle de la parole par VMike
This article presents a new Electronic Retina based Smart Microphone (VMike) and investigates the use of its novel parameters – lip profiles – in audiovisual speech recognition. In order to evaluate the parameterization, both an audio only and a video only speech recognition system are developed and tested. Then, two main fusion techniques are employed […]
