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

Abstract

The invention relates to an automatically adjustable pharyngeal electronic laryngeal speech synthesis and communication system and method, based on a computer software platform and external hardware equipment, including a camera, a microphone and an electronic laryngeal oscillator, by extracting moving images of the user's face and neck The visual voice feature information realizes the automatic control of the working state of the electronic laryngeal and the synthesis of the pharyngeal voice source, which not only makes the use of the electronic laryngeal more simple and convenient without the need for hand-holding, but also solves the problem of inconsistency between the synthetic voice source and the electronic laryngeal application site and the electronic In order to solve the mechanically unnatural problem of laryngeal speech, at the same time, dynamic denoising and enhancement processing is performed on the reconstructed speech of the electronic laryngeal cavity of the pharynx, which improves the quality and intelligibility of the reconstructed speech, and realizes the remote real-time communication of electronic laryngeal speech through network transmission technology, further The scope of application of the electronic larynx has been expanded, and the quality of life of patients with laryngectomy has been improved.

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.
