Abstract
A brain-computer interface (BCI) is a form of technology that develops a communication channel between a user and certain environmental objects using the user's brain impulses and to develop a non-invasive brain-computer interface that can "translate ideas into voice" (that converts brain signals into speech). The technique is primarily intended for individuals who can no longer interact via conventional channels (lock-in-syndrome patients). The brain signal produced for each word is recorded using EEG electrodes, and the ADC is used to convert the recorded brain signal to a voltage value. When the system produces the requisite voltage, the voice is delivered. Keywords: Brain, EEG electrodes, Thoughts, Speech, Non-Invasive, Signal processing, Word, ADC
