rticulate offers a few helper functions to work with ultrasound tongue imaging data, exported from Articulate Assistant Advanced™ or other systems.

The following vignettes give details on specific topics:

• vignette("tongue-imaging", package = "rticulate"): You should start here to learn how to import AAA and EMA data.
• vignette("polar-gams", package = "rticulate"): This vignette describes the function polar_gam() which can be used to model tongue contours with GAMs using polar coordinates.
• vignette("transform-coord", package = "rticulate"): In most cases, you won’t need to convert to polar coordinates explicitly, but in case you want to do that, you can look at this vignette to learn how to use transform_coord().
• vignette("filter-signals", package = "rticulate") illustrates the filtering capabilities of the package.
• `vignette("kinematics", package = "rticulate") shows examples of how to detect gestural landmarks from articulator displacement signals.
