Ultraspeech-aquisition allows the synchronous acquisition of high-speed ultrasound and video images of the vocal tract together with the audio speech signal. 

Ultraspeech-aquisition was originally designed for the portable ultrasound machine Terason T3000 (laptop/OEM version) but is now also compatible with Telemed systemsUltraspeech is compatible with the WDM-compliant industrial cameras provided by Imaging Source and ASIO / DirectX compatible soundcards. 

Ultraspeech-aquisition is “user friendly”. The entire recording procedure is fully automatic (push-button like) and no a posteriori human check is needed. After each acquisition, data are directly available as series of bitmaps for both image streams and WAV files for the audio stream, in the specified directory. Ultraspeech provides also convenient tools for large database recording, such as an automatic file naming system, the automatic display of the text stimuli and finally, an interactive inter-session re-calibration mechanism that allows recording of large audiovisual speech databases in multiple acquisition sessions.
