The goal of the present study is to introduce a speaking interface of mobile devices for speech impaired people. The latest devices (including PDAs with integrated telephone, Smartphones, Tablet PCs) possess numerous favorable features: small size, portability, considerably fast processor speed, increased storage size, telephony, large display and convenient development environment. The majority of vocally handicapped users are elderly people who are often not familiar with computers. Many of them have other disorder(s) (e.g. motor) and/or impaired vision. The paper reports the design and implementation aspects of converting standard devices into a mobile speaking aid for face-to-face and telephone conversations. The device can be controlled and text is input by touch-screen and the output is generated by a text-to-speech system. The interface is configurable (screen colors and text size, speaking options, etc.) according to the users’ personal preferences.
