Embodiment Construction

[0028] The specific implementation manners of the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0029] figure 1 A preferred embodiment of an artificial throat according to the present invention is shown. like figure 1 As shown, the artificial larynx includes a voice transducer 100 , a voice detection system 200 and a voice generation system 300 . Wherein, the voice converter 100 is used to detect the vibration of the throat, and convert the vibration signal into a resistance signal; the voice detection system 200 is used to collect and analyze the above resistance signal, and infer the voice to be issued by the user according to the change of the resistance value; The voice generating system 300 is used to generate a corresponding electrical signal according to th...

Abstract

The invention relates to the technical field of assisted sound production for patients with language disorder, and discloses an artificial larynx. The artificial larynx comprises a sound converter, a voice detection system and a voice generating system, wherein the sound converter is used for detecting vibration of the larynx and for converting a vibration signal to a resistance signal; the voice detection system is used for acquiring and analyzing the resistance signal and deducing out voice which is to be produced by a user in accordance with the situation on resistance change; and the voice generating system is used for generating an electrical signal in accordance with the voice which is to be produced by the user and transmitting the electrical signal to the sound converter, so that the electrical signal, by virtue of the sound converter, can be converted into a sound signal. The artificial larynx provided by the invention, which can be attached to a neck from outside, is good in biocompatibility and is free from discomfort; and in addition, the artificial larynx is simple in structure, high in stability, high in sound production precision, low in manufacturing cost and easy for implementation of industrialization. The invention also discloses a sound conversion method of the artificial larynx.

Description

technical field [0001] The present invention relates to the technical field of assisted vocalization of patients with speech impairment, in particular to an artificial larynx and a sound conversion method for the artificial larynx. Background technique [0002] There are millions of patients with language disorders in the world, some of them have language dysfunction due to congenital defects, and some of them lose their language function due to some acquired diseases. Language dysfunction has brought great difficulties and inconvenience to their lives . The famous physicist Hawking suffered from Parkinson's disease and could not communicate with people normally through language. Engineers from Intel Corporation designed a typing system based on eye tracking technology for him, which can select the words to express by rolling the eyeballs. content, however, its technical cost is extremely high, and it is difficult to popularize and promote it. In addition, artificial laryn...
