Device and method of voice detection and evaluation based on mobile terminal

Abstract

The invention discloses a device of voice detection and evaluation based on a mobile terminal. The device of the voice detection and evaluation based on the mobile terminal comprises a voice detection and evaluation terminal, wherein the voice detection and evaluation terminal comprises a signal collection and data storage unit, a voice signal processing and evaluation unit and a data output unit. The mobile terminal is adopted by the voice detection and evaluation terminal. The signal collection and data storage unit comprises a voice signal collection module, a voice signal data storage module and a detection and evaluation result storage module. The voice signal processing and evaluation unit comprises a voice signal processing module, a voice signal cycle detection module, a feature parameter extraction module and a voice signal feature evaluation and analysis module. The data output unit comprises a voice signal output module, a voice signal waveform drawing module and a detection journal visiting module. The device and the method of the voice detection and evaluation based on the mobile terminal have the functions of the voice signal collection, process, analysis and evaluation. The device of the voice detection and evaluation based on the mobile terminal has the advantages of being convenient to carry, low in cost, insensitive in gender difference and the like.

Description

technical field [0001] The invention relates to the technical field of mobile terminals and voice detection, in particular to a mobile terminal-based voice detection and evaluation device and method. Background technique [0002] With the development of medical technology and the improvement of people's health awareness, people pay more attention to the impact of voice diseases on the quality of life. Voice acoustic assessment, laryngeal function testing, voice correction and health care have become new development trends in otolaryngology. However, with the aging of the population and the increasing proportion of the population with chronic diseases, traditional medical services are facing enormous pressure and challenges. Therefore, a portable, low-cost, and effective voice analysis and detection system is urgently needed. [0003] At present, electronic computers and spectrum analyzers are mainly used at home and abroad to collect, analyze, and count voice samples for ac...

Problems solved by technology

[0005] However, the above-mentioned systems and software are expensive, and due to time and environmental constraints, they cannot analyze and evaluate voice signals conveniently and quickly anytime and anywhere. The applicable population is very small, and they have not been popularized at home and abroad.

[0006] Nowadays, mobile terminals (such as mobile phones, handheld computers, etc.) have developed very rapidly, and their computing speed and ability are amazing, and they have been popularized in a wide range. The number of people who need to evaluate their voices is increasing (teachers, musicians, etc.), but Voice evaluation system based on mobile terminal is still blank

In addition, due to the variability of voice signals, a perfect method has not been found so far to obtain satisfactory detection results for various groups of people and under various environmental conditions, and there is also a lack of consideration of gender differences.

[0007] At present, there are some patents on voice analysis or performance evaluation, but some of them are aimed at evaluating the voice performance of specific groups of people (Dmitry Golovkin, Cui Zhemin. The method for evaluating the singer's voice performance and the use of this method equipment. CN101740025A_200910.), some provide a voice harmonic-to-noise ratio analysis method (Yan Yonghong, Wang Di, Zhang Jianping. An automatic voice harmonic-to-noise ratio analysis method. CN101452698_200710.), and some hardly involve voice physiological parameters (KAY ELEMETRICS CORP.Speech analysis apparatus.US23732081A_1981-2-23.), all lack a system that can be applied to various groups of people more conveniently and can analyze and evaluate important physiological parameters
