The tongue is the most complicated pronunciation organs in the motion in the speech，Its changes can be captured by speech ultrasound collectors。The speech ultrasound collector of the Voice Bet365 gamesLaboratory of Shandong University is Micro Speech, produced by Articulating Instruments Company。
1. Hardware system
Host、Adult ultrasound probe (radius 20mm，frequency 2-4MHz，The largest FOV92 & Deg;)、Children's ultrasound probe (radius is 10mm，frequency 5-10MHz，The largest FOV150 & Deg;)、Synchronous control unit、pulse unit、Audio and video synchronization unit、Wear Device、Video collection camera、Speaker、microphone
2. Instrument connection
(1) Ultrasonic device
Fix the ultrasound probe on the header device，Connect the ultrasound host at the other end，Access to bet365 live casino bettingthe synchronous control unit through pulse unit。
(2) Audio and video collection device
Connect the video collection camera and external microphone to the audio and video synchronization unit，Output access to synchronous control unit。Video signals are connected to the video collection card from the audio and video synchronous unit output interface，From the computer。
3, signal collection
The Test of the Test of the Wear Device Pronunciation，The voice signal when the main test is recorded at the same time、Lip -shaped image and the imaging of the tongue movement trajectory。
4. Data analysis
bet365 live casino bettingDetermine the key frame，Use 2D strips to mark the tongue position，Draw the fan chart for the tongue position，Statistical analysis data; at the same time, the resonance peak parameters of the voice signal can be analyzed。
5. Application field
Speech Ultrasonic Collector as a pronunciation visual biological feedback tool，It is widely used in linguistic research and verbal pathological research。
Linguistics Research: Modeling of Word Engineering、Linguistics field survey、Language acquisition and two -language teaching、Art sound。
Speech and pathological Bet365 gamesresearch: Clearing lip and palate voice disorder、Sound disorder、Fluent Dorde。
