by those people who have lost their voice box, usually due to cancer of the larynx. The most common device is a handheld, battery-operated device pressed against the skin under the mandible which produces vibrations to allow speech; other variations include a device similar to the " talk box" electronic music device, which delivers the basis of the speech sound via a tube placed in the mouth. Earlier non-electric devices were called mechanical larynxes. Along with developing esophageal voice, using a speech synthesizer, or undergoing a surgical procedure, the electrolarynx serves as a mode of speech recovery for laryngectomy patients.

. It did not run on electricity, and was flawed in that it produced a strong voice. Electrolarynxes were introduced in the 1940s, at a time when esophageal speech was being promoted as the best course in speech recovery; however, since that technique is difficult to master, the electrolarynx became quite popular. Since then, medical procedures, such as the tracheo-oesophageal puncture, and the rarely performed laryngeal transplantation surgery, have been created to enable speech without continued dependence on a handheld device. The use of an electrolarynx can cause social issues, for instance difficulty ordering food, drinks, or other items in noisy environments; or, when answering a telephone, having the caller respond, "Am I talking to a computer?" However, quality-of-life improvements due to electrolarynx usage are generally significant. One user states: Traditional electrolarynxes produce a monotone buzz that the user articulates into speech sounds, resulting in the characteristic "robotlike" voice quality. However, in the 1990s, research and commercial multi-tone devices began to be developed, including discrete-tone devices using multiple-position switches or multiple buttons; as well as variable-tone devices controlled by single pressure-sensitive buttons, trackballs, gyroscopes, touchpad-like input devices, or even electrical detection of the movement of neck muscles. In addition to allowing speakers of non- tonal languages such as English to have a more natural speaking voice, some of these newer devices have allowed speakers of tonal languages such as Mandarin Chinese to speak more intelligibly.
