What accessibility solution is most suitable for users with hearing impairment?

A transcript of audio is the most suitable accessibility solution for users with hearing impairment because it provides a written representation of spoken content. This allows individuals who are deaf or hard of hearing to access the information conveyed through audio, whether it be in a lecture, video, or meeting. By converting audio into text, users can follow along and understand the material that they would otherwise miss due to their hearing difficulties.

Considering the other options, easily read fonts, while important for general accessibility, do not specifically address the needs of users with hearing impairments. Textual descriptions of images serve to provide context to visuals for individuals who cannot see well, but they don't assist with auditory content. Screen reading conversion is designed primarily for users with visual impairments, enabling them to access text by having it read aloud, which is not relevant for those who rely primarily on textual information due to hearing challenges.
