SIVHA, visual speech synthesis system

Abstract

This paper presents SIVHA, a high quality Spanish speech synthesis system for severe disabled persons controlled by their eye movements. The system follows the eye-gaze of the patients along the screen and constructs the text with the selected words. When the user considers that the construction of the message has been finished, the synthesis of the message can be ordered. The system is divided in three modules. The first one determines the point of the screen the user is looking at, the second one is an interface to construct the sentences and the third one is the synthesis itself.
