Abstract
Loss of voice is a serious concern for a laryngectomee which should be addressed prior to planning the procedure. Voice rehabilitation options must be educated before the surgery. Even though many devices have been in use, each device has got its limitations. We are searching for probable future technologies for voice rehabilitation in laryngectomees and to familiarise with the ENT fraternity. We performed a bibliographic search using title/abstract searches and Medical Subject Headings (MeSHs) where appropriate, of the Medline, CINAHL, EMBASE, Web of Science and Google scholars for publications from January 1985 to January 2020. The obtained results with scope for the development of a device for speech rehabilitation were included in the review. A total of 1036 articles were identified and screened. After careful scrutining 40 articles have been included in this study. Silent speech interface is one of the topics which is extensively being studied. It is based o n various electrophysiological biosignals like non-audible murmur, electromyography, ultrasound characteristics of vocal folds and optical imaging of lips and tongue, electro articulography and electroencephalography. Electromyographic signals have been studied in laryngectomised patients. Silent speech interface may be the answer for the future of voice rehabilitation in laryngectomees. However, all these technologies are in their primitive stages and are potential in conforming into a speech device.
