Embodiment 1

[0040] Embodiment 1: longest sound time data measurement

[0041] In this embodiment, the input voice is the vowel / a / in Mandarin Chinese, and the speaker is a male. When the target detects the longest sound, the collection device 1 collects the speech data of the user's vocalization process. like image 3shown. The calculation device 2 calculates the length of the voice data in the time domain to obtain the longest sound time, which is a parameter value of the voice data. The judging device 3 compares the parameter values ​​of the user with the standard numerical ranges corresponding to their age and gender according to the user's information, and if the parameter values ​​are within the standard numerical ranges, it means that the user's speech breathing ability is normal; otherwise , it indicates that there is a speech impairment, and the impairment is insufficient respiratory support.

Embodiment 2

[0042] Embodiment 2: fundamental frequency data measurement

[0043] In this embodiment, the user utters in the form of rising pitch, falling pitch and rising and falling pitch, and the collection device 1 collects speech data of the user's vocalization process. like Figure 4 shown. The calculation device 2 calculates the voice data in the time domain and the frequency domain to obtain fundamental frequency data, which is a parameter value of the voice data. The judging means 3 compares the user's parameter values ​​with the standard numerical ranges corresponding to their age and gender according to the user's information, and if the parameter values ​​are within the standard numerical ranges, it means that the user's ability to change pitch is normal; otherwise , it indicates that there is a speech impairment, specifically an impairment of the ability to change intonation.

Embodiment 3

[0045] Embodiment 3: glottal wave data measurement

[0046] In this specific embodiment, the input voice is , its sound wave is like Figure 5 As shown, the speaker is a male, and the target detection fundamental frequency perturbation and speed are two speech data. The acquisition device 1 collects the speech data in the sound wave, and the calculation device 2 calculates the speech data to obtain the glottal wave value and its waveform. The waveform is as follows Image 6 As shown, the user can observe the waveform.

[0047] The calculation device 2 calculates the fundamental frequency perturbation of the sound wave to obtain its fundamental frequency perturbation data. The fundamental frequency perturbation value of the sound wave is 0.3, while the fundamental frequency perturbation value of a normal adult is about 0.8. The calculation device 2 then analyzes the sound waves to obtain the quotient data. The quotient value of a normal adult in the stable period should be ...

Abstract

The invention discloses a system for lalopathy multi-dimensional measurement on the basis of real-time speech multi-dimensional modeling. The system comprises a collecting device, a calculating device and a judging device, wherein the collecting device collects speech data, the calculating device calculates parameter values of the speech data, the judging device enables the parameter values to be compared with a standard numerical range of the speech data, and if the parameter values are within the standard numerical range, lalopathy does not occur; and if the parameter values are lower than or higher than the standard numerical range, the lalopathy occurs and a lalopathy type is judged. The problem of lalopathy can be reflected comprehensively, assessment on lalopathy patients is more accurate, and rehabilitation training of the lalopathy patients is more comprehensive and targeted. The invention further discloses a method for lalopathy multi-dimensional measurement on the basis of real-time speech multi-dimensional modeling.

Description

technical field [0001] The invention belongs to the technical field of medical devices, and in particular relates to a multidimensional measurement system and method for speech impairment based on real-time speech multidimensional modeling. Background technique [0002] In clinical medicine, any pathological phenomenon that affects the basic speech communication process through audio-visual channels is a speech disorder. It includes many aspects, which can be organic lesions or functional disorders. The clinical manifestations of speech disorders are very diverse, and the situation varies from person to person. They all have different manifestations in the stages of breathing, vocalization, resonance, articulation, and pronunciation, and even affect each other. Therefore, the evaluation of speech disorders is very important. Important diagnostic module. [0003] Domestic evaluation of speech impairment includes two aspects: subjective evaluation and objective measurement. ...
