I. main USES:

The system is used for diagnosis, evaluation and rehabilitation training and guidance of articulation disorders. The system scientifically evaluates the articulation function of patients from the perspective of pronunciation and movement, so as to diagnose the dual latitude causes of physiological and phonetic levels of articulation disorders caused by patients, and provide specific individualized articulation rehabilitation training programs.

Ii. Main functions:

1. Measurement and evaluation of articulation and speech disorders

1) assessment function module: the assessment of articulation function is divided into organ assessment, motor assessment, pronunciation assessment and conversation assessment, and the assessment mode is divided into subjective assessment and objective assessment. The combination of the two makes it more convenient for therapists to selectively evaluate the actual level of trainees.

2) parameter data analysis: the system can analyze the phonetic parameters such as oral rotation movement rate, mandibular distance, tongue range distance, tongue distance, dullness start time, phonetic sign length, trend, air supply time ratio, dullness ratio, speech type and articulation clarity, as well as the related tongue map and acoustic map.

3) exercise assessment: including core rhyme, larynx, respiration, velopharyngeal mechanism, lip, jaw, tongue, oral rotation, etc

4) pronunciation evaluation: including single vowel, compound vowel, nasal vowel, consonant, tone, etc.

5) conversational assessment includes expression level, information expression, mental state, attention, volume, voice analysis, etc.

6) personalized rehabilitation plan: according to the assessment results of articulation function, therapists make personalized rehabilitation training plans with different difficulty and sensitivity.

2. Rehabilitation training for articulation and speech disorders

1) rehabilitation training module: rehabilitation training includes abnormal articulation correction training, articulation organ movement training, articulation movement training and other articulation rehabilitation training.

2) speech correction induction: a variety of voice-controlled games are provided during the training, which can provide real-time visual feedback on vocalization, attract children's interest in training, and improve the laborious and tense situation of children's vocalization.

3) real-time oral exercise therapy: real-time speech track shape modification is adopted for oral and articulation analysis, and resistance exercise training and strengthening exercise training of jaw, lip and tongue are conducted through a variety of training methods, so as to improve the muscle strength and stability of corresponding muscle groups, and improve the range and accuracy of articulation organ movement.

4) real-time articulation exercise training: using real-time speech track shape correction to analyze vowel and vowel, combining Chinese vowel, vowel and tone to carry out articulation exercise training of jaw, lip and tongue, so as to improve the accuracy of articulation organ movement and improve articulation clarity.

5) the system provides corresponding four training modules of speech perception, speech learning, speech comparison and speech application.

6) phonological awareness vowel training: including single vowel training, compound vowel training and nasal vowel training.

7) real-time articulation and phonological self-feedback training: phonemic perception, phonemic acquisition, phonemic comparison and phonemic enhancement training can be carried out to establish a smooth speech auditory chain for patients and promote the efficiency of rehabilitation.
