Abstract

The invention discloses a multi-dimensional dysarthria measuring system based on real-time vocal tract shape correction. The multi-dimensional dysarthria measuring system comprises a voice input unit, an analysis unit, a marking unit, a parameter setting unit and a model generating unit, wherein the voice input unit is used for inputting voice files to analyzed; the analysis unit comprises an unvoiced and voiced sound type distinguishing module for distinguishing unvoiced and voiced sound types, a formant extraction module for extracting formants and a spectrogram analysis module for spectrogram calculation; the marking unit is sued for marking key frames of the formants according to the formants and spectrograms; the parameter setting module is used for setting and adjusting vocal tract shape parameters; the model generating unit is used for drawing the key frames into a vocal tract shape model according to the vocal tract shape parameters. The system displays movement conditions of articulators intuitively and monitors related parameters of the articulators to achieve articulation self feedback of dysarthria recovery trainings. According to the system, the method level and the modern technical level are combined to form a real-time vocal tract shape correction technology. The invention further discloses a multi-dimensional dysarthria measuring method based on the real-time vocal tract shape correction.

Description

technical field [0001] The invention belongs to the field of speech and hearing rehabilitation, and in particular relates to a multidimensional measurement system and method for dysarthria based on real-time vocal tract shape correction. Background technique [0002] Dysarthria is a very common category of speech disorders. It refers to the phenomenon of unclear articulation and abnormal sound and tone in the process of uttering meaningful speech due to abnormal movement of articulatory organs or coordination movement disorder. Its main manifestations are: The intelligibility of speech is reduced, thereby affecting the intelligibility of speech. Dysarthria is divided into two levels: dysarthria and dysarthria, among which dysarthria is an internal problem, which directly manifests as a decrease in speech clarity and is an internal factor that affects daily life and verbal communication. Therefore, a comprehensive , Accurate assessment of articulation and motor function is a...
