What type of communication system relies on residual hearing along with speech and speechreading?

The chosen response refers to an oral communication system, which specifically utilizes residual hearing, speech, and speechreading as its foundational elements. This approach is designed for individuals who are deaf or hard of hearing and still have some degree of hearing ability. The goal is to enhance understanding and communication through the use of whatever hearing capabilities are available, combined with visual cues from lip movements and facial expressions to support spoken language comprehension.

The reliance on these multimodal communication strategies helps to bridge the gap for individuals who may struggle with auditory information alone. By focusing on oral communication, the individual learns to maximize their hearing potential while also observing the speaker’s mouth movements, thus allowing for a more complete understanding of the spoken message.

In contrast, the other options represent distinct communication methods. A manual communication system pertains primarily to the use of hand gestures or signs to convey meaning, which does not involve residual hearing in the way oral communication does. Sign language is a fully developed linguistic system that does not rely on speech or residual hearing but rather on visual signs. Auditory-verbal communication focuses more on developing spoken language through listening without relying primarily on visual gestures or sign language, thereby not emphasizing speechreading to the extent that an oral communication system does.
