Speech Application Language Tags (SALT) are generic markup tags that can be used to implement speech-based interfaces on top of SALT-enabled browsers. SALT provides low-level speech-to-text, text-to-speech, and telephony services so that application developers can incorporate speech into their applications. SALT provides a great deal of flexibility to its users, it enables developers to produce highly usable and sophisticated speech-enabled applications, but it also enables complex and unusable user interfaces. One method for solving this problem is to provide higher-level user interface components using speech (high-level speech interactors) based on SALT that developers can use in their applications. If the high-level interactors are well designed and usable, they should make it easier to develop speech-enabled applications with effective user interfaces. We used SALT, JavaScript and XHTML to implement high-level speech interactors. We performed experiments to evaluate the usability of the interactors using performance and preference metrics. We created a final report summarizing all the work done for this project. Finally we made a presentation to our Computer Science class at Portland State University. |
