What communication system uses a combination of speech and signs?

The correct answer is Simultaneous Communication, which is a method that combines spoken language with sign language, allowing individuals to convey messages through both auditory and visual means at the same time. This approach is particularly beneficial for individuals who may have varying degrees of hearing loss or are in environments where full access to one mode of communication is not feasible.

Simultaneous Communication can enhance understanding and engagement, as it provides multiple avenues for receiving information. This is especially important in educational and therapeutic settings, where comprehensibility and reinforcement of spoken language through visual cues can aid learning and communication effectiveness.

The other options represent different forms of communication that do not utilize this combination. Oral communication focuses solely on verbal expression without the visual support of signs. American Sign Language, while an effective communication system on its own, does not involve simultaneous spoken language use. Fingerspelling is a specific technique used within signing to spell out words but is not used in conjunction with speech as part of a broader communication strategy.
