A python module for processing ELAN and Praat annotation files

Project description


Pympi is a package that allows you to interact with Elan files and TextGrid files. You can create, edit and convert both formats into each other. It includes besides all the basic functions also functions for: - Calculating gaps and overlaps between speakers conform Heldner and Edlund’s method. (Could be used to calculate floor transfers) - Shift annotations in both directions (Could be used when due to an error all annotations are misaligned). - Import from CLAN’s chat files. - Merge and or filter tiers (Could be used to combine hands in gesture coding) - Move tiers between elan files. - Etc.
