Pharyngeal cavity electronic larynx voice communication system capable of being automatically regulated and method

Abstract

The invention relates to a pharyngeal cavity electronic larynx voice synthesis and communication system capable of being automatically regulated and a method. The pharyngeal cavity electronic larynx voice synthesis and communication system is based on a computer software platform and external hardware equipment, and comprises a camera, a microphone and an electronic larynx oscillator. Automatic control for the working state of the electronic larynx and voice source synthesis of the pharyngeal cavity is realized through extracting visual phonetic feature information of movement images of the face and the neck of a user, thereby not only enabling the electronic larynx to be used without being held by hands so as to be simpler and more convenient, but also solving problems that the synthesisvoice source is not consistent with the electronic larynx in application part and the voice of the electronic larynx is mechanical and unnatural. Meanwhile, dynamic de-noising enhancement treatment isperformed on the reconstructed voice of the pharyngeal cavity electronic larynx, thereby improving the quality and the intelligibility of the reconstructed voice. Remote real-time communication of the electronic larynx is realized through a network transmission technology, thereby further expanding the application range of the electronic larynx, and improving the life quality of a patient after laryngectomy.

Description

technical field [0001] The invention belongs to the technical field of lesion voice reconstruction and voice communication, and in particular relates to a pharyngeal cavity electronic laryngeal voice communication system and method which can be automatically adjusted. Background technique [0002] Every year in our country, a large number of patients lose their voice ability due to laryngectomy, and the electronic larynx in the prior art is widely used because of its wide application range, simple operation, long-term vocalization and easy understanding. However, the current electronic laryngeal voice is unnatural, inconvenient to use, and has a large component of radiation background noise and environmental noise, which seriously affects the understanding and pleasantness of voice. [0003] At present, the electronic larynx used at home and abroad is mainly the external neck type. The working principle is that the waveform generator provides the waveform of the glottal voic...

AI Technical Summary

Problems solved by technology

[0006] Aiming at the disadvantages of difficult use, complicated training methods, and high cost in the application of the above-mentioned prior art electronic laryngeal, the present invention provides an automatically adjustable pharyngeal electronic laryngeal voice communication system and method. The system is based on a computer hardware system. Mainly, through software development, the pharyngeal voice source synthesis based on the automatic adjustment of facial and neck movement characteristics has been realized. The electronic laryngo does not need to be hand-held and is easy to use. The network real-time communication of electronic throat voice has been expanded, and the function of electronic throat has been further expanded.
