This paper discusses the implementation of accessibility features for visually impaired people in synchronous and cooperative systems on the Internet. Based on the sociocultural scenario of affirmation of difference and on the contexts of cooperation established by Web 2.0, we discuss the application of Sound Workspace Awareness in Groupware tools through Auditory Icons, Earcons, synthesized speech, Live Region, and Screen Readers in a Web chat system. The article presents a qualitative experimental research with internal data validation and an exploratory goal. The process of data collection and analysis was performed using protocols applied with five real users. The results of the experiments showed a satisfactory adherence of these technologies in the construction of Sound Workspace Awareness to screen reader users.
