The recommended way to acquire ultrasound data in the Phonology Lab is via an Opensesame experiment. You can use Opensesame to display a series of prompts to a subject and run and control the acquisition utilities in inline scripts. A simple experiment proceeds like this:
- variables related to data acquisition are set
- the ultrasound acquisition system is initialized
- the experiment loops over a list of stimuli, which are used to prompt the subject
- a preparatory prompt is shown to the subject
ultrasession.pyis started and delays until the ultrasound system confirms that it is imaging- a speaking prompt is shown to the subject. This prompt can be shown for a defined duration, or it can be displayed until the subject presses a key.
ultrasession.pyis sent a signal to stop acquisition
