Our research, conducted at the Institut de la Communication Parlée (ICP, Institute of Speech Communication, Grenoble, France) focuses on understanding the temporal relationship between the manual components of Cued Speech (CS) and the non-manual mouth movements in order produce a virtual cueing head/hand for text-to-CS processing. In the first part of the chapter, we describe our research findings related to the temporal relationship between the production of the manual components of CS and the non-manual components of CS and also to how deaf users of CS predict the next syllable or word. This will be discussed in the context of a perceptual and cognitive control approach. In the second part of the chapter, we describe our findings related to our complete system of text-to-cued speech audiovisual synthesis based on the temporal relationship principles described in Part I of this chapter together with preliminary evaluation of the intelligibility of the output of the synthesizer. This latter is finally discussed in the framework of an application to the television.
