The article identifies and describes testing methods that take into account the specifics of perception and orientation in the interface of such users. Interaction with voice interfaces creates a number of difficulties for users who use screen readers, as it requires the development of special approaches to create an accessible and user-friendly interface. Throughout the course of this work, the functional and cognitive aspects of voice interaction were investigated, compatibility with screen readers was evaluated, and synchronization of audio streams was studied.

Scientific articles were used as methodological sources, and for the practical part of the work, data contained in open access on the Internet was used, which made it possible to widely consider the chosen topic and form one's own position on the topic under consideration.

The results of the analysis showed that improved audio stream management and command settings reduce the burden on information perception and make it easier to interact with the interface. The conclusion of the work emphasizes the necessity of conducting tests in real-world conditions, considering the characteristics of the target audience.

The information presented in this article will be valuable to developers, designers, and testers who are interested in creating inclusive applications for visually impaired users.
