Answer :
Final answer:
The computer peripheral that allows a student with an expressive language disorder to hear his own voice is a speech synthesizer or VOCA. Typically connected to a computer or tablet, this technology transforms input into spoken language. Its principles are akin to those used in brain-computer interface technology and cochlear implants.
Explanation:
The computer peripheral that permits a student with an expressive language disorder to hear his own voice is a speech synthesizer or voice output communication aid (VOCA). This device can be linked with various forms of technology but is usually paired with a computer or tablet. It works by capturing the person's input whether typed or selected from pre-programmed phrases or words. The selected message is then converted into digital language and used by the synthesizer to create an output in the form of speech.
The technology mirrors the principles used in brain-computer interface technology, where neural signals are collected, decoded, and fed into a tool, such as a computer. This is the same technology that allows paralyzed patients to type sentences by twitching. Additionally, it is similar to the technology in the cochlear implant, a groundbreaking device that converts electric signals into impulses understandable by the brain.
