Communication is a key factor in a developing society. It is usually carried out by using signals that come from the brain, and then produced as sounds in the Place of Articulation. An alternative to this type of communication is subvocal speech or “subvocalization”, which consists in the acquisition of the signals produced in the cerebral cortex and their analysis before the voice production process in the Place of Articulation is made. This paper proposes a prototype system for acquisition of the signals produced in the Place of Articulation; by using a Data Acquisition System (DAS) and MATLAB® as a tool for comparing the obtained results.
