The tongue is the articulator with the most complex movement trajectory in speech production，The changes can be well captured by speech ultrasound collector。The speech ultrasound acquisition instrument of Shandong University bet365 live casino reviewino blackjackSpeech Laboratory is Micro Speech produced by Articulate Instruments。
1. Hardware system
Host、Adult ultrasound probe (radius 20mm，Frequency 2-4MHz，Maximum FOV92°）、Children’s ultrasound probe (radius 10mm，Frequency 5-10MHz，Maximum FOV150°）、Synchronization control unit、Pulse unit、Audio and video synchronization unit、Headset、Video capture camera、Speaker、Microphone
2. Instrument connection
(1) Ultrasonic device
Attach the ultrasound probe to the headset，The other end is connected to the ultrasound host，Connect to the synchronization control unit through the pulse unit。
bet365 online casino(2) Audio and video collection device
Connect the video capture camera and external microphone to the audio and video synchronization unit，Output access synchronization control unit。The video signal is simultaneously connected to the video capture card through the output interface of the audio and video synchronization unit，Connect to the computer here。
3. Signal collection
The subject wore the headset to pronounce the words，The examiner simultaneously recorded the speech signal during pronunciation、Lip shape image and tongue movement trajectory imaging。
4. Data Analysis
bet365 live casino bettingDetermine keyframe，Use 2D spline to mark tongue position，Draw a sector diagram for tongue position tracking，Data obtained from statistical analysis；At the same time, the formant parameters of the speech signal can be analyzed。
5. Application fields
Speech ultrasound acquisition instrument as a visual biofeedback tool for articulation，Widely used in linguistic research and speech pathology research。
Linguistic Research: Speech Engineering Modeling、Fieldwork in Linguistics、Language acquisition and second language teaching、Artistic Voice。
Speech Pathology Research: Cleft Lip and Palate bet365 games best slotsSpeech Disorder、Dysarthria、Fluency barriers。
