The design of a wireless-controlled intra-oral electrolarynx.
Many patients who have failed to acquire esophageal speech after total laryngectomy are presently using artificial electrolarynges. Two of the principle objections to currently available devices are their bulkiness and visibility. The authors have developed and tested a wireless-controlled intra-oral electrolarynx which overcomes these main objections. In addition, it produces intelligible speech which compares favorably with other existing devices. In this paper, the design details will be presented which significantly influence the performance and the patients' acceptability of the new device.
