HAND PROSTHESIS CONTROLLED BY VOICE RECOGNITION

Currently, mechatronic prostheses have acquired high importance for the rehabilitation of disabled people who have suffered from the loss of a limb, allowing them to resume certain activities on their own. However, the cost and functionality are not always adequate, making them useless for the majority. The present invention discloses the creation of a hand prosthesis controlled by voice recognition with CAD design, 3D printing technology, control by voice recognition with a specialized module, and activation of the fingers of the hand prosthetics to have a reliable and selective alternative that facilitates the execution of specific movements. Also, it aims to provide a hand prosthesis controlled by voice commands for manipulating several objects and performing various tasks. It discloses each of the parts that make up the electromechanical prosthesis, including the mechanical system articulated with artificial tendons and an electrical system for their manipulation, incorporating se rvomotors for producing the necessary angular movement of flexion and extension of each of the fingers for a given activity, incorporating actions to control a computer mouse by defining short voice commands to facilitate recognition and obtain a favorable system response. Also, it describes the software of the voice recognition module and the generic processor that work together and governs the servomotors and the tests performed. The present invention discloses the operation of a voice-controlled electromechanical hand prosthesis, developing the mechatronic discipline to improve performance in certain activities, executing actions to control a computer mouse, and providing some independence for people disabled by trans-radial amputation. The processing of the commands benefits by being in an environment with the least possible noise; however, when using short words, they can work in an unfavorable environment, even recognizing if there is external noise that could interfere. The mod ule for voice command recognition is simple to interact with since the disabled person only has to train the system of commands that executes the action, regardless of the conditions of the muscles of the stump. En la actualidad, las prótesis mecatrónicas han adquirido gran importancia para la rehabilitación de personas discapacitadas que han padecido de la perdida de alguna extremidad permitiéndoles retomar ciertas actividades por sí mismas, sin embargo, debido al costo y a una funcionalidad no
