, and was flawed in that it produced a strong voice. However, more recent mechanical larynxes have demonstrated similar voice production to commercially available electrolarynxes. 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

, 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,
