Lip reading based on background subtraction and image projection

Someone who does not have vocal cords, has no ability to produce voice and speech. This problem is suffered by laryngectomy patients. Over half of all laryngectomy patients worldwide are using electrolarynx for the rehabilitation of their speech ability. Unfortunately, the electrolarynx is relatively expensive, especially for patient from the lower classes. In this research, portable speech aid tool for laryngectomy patient based on lip reading is studied, especially for who use Indonesian language. Two problems in a lip lip reading system, especially if it run in portable device, are lighting and limited resources. Background subtraction and image projection method are studied in this research to overcome these two problems.
