Punch List for ultrasound studies
Preparation
- recruit subject
Data Collection
- set up machines
- participant reads and signs consent form; describe procedure; answer questions
- set up participant in chair
- record on imovie (mac)
- thank participant
Post Processing
- save entire recording as .mov (Export) for backup purposes
- save each presentation as a smaller .mov
- rip audio of smaller .mov files
- make jpegs of smaller .mov files using ImageJ
- transcribe audio files using transcriber (cut and past in protocol)
- send txt file and wave to forced aligner (returns a TextGrid)
- manually fix alignment in Praat’s TextGrid
- run Praat script to grab target information including times
- use Edgetrak to grab the tongue shapes at the same times as the head and tails of the vowels
- use NORM to plot the vowels (target and reference vowels) in Bark normalized vowel space
- use R to analyze the variance between tongue shapes at head and tail for each vowel
At the end you should have a vowel space plot and a tongue shape plot for each participant.
