PLOTNIK09 is the latest version of the program.

Plotnik09 is a new version of Plotnik with two major changes from Plotnik08. • There is no longer a quota system for token buttons for each vowel class. Instead, the appropriate symbols needed are created each time a new vowel file is called up. This has immediate consequences for the Save Plot and Recall Plot functions. In Plotnik08, these functions only worked if one preserved the same button quotas: this problem is now done away with, and Recall Plot now returns a complete functioning vowel file where you last left it, for reproduction or conitnued development • Under the View menu, the selection of large screen size is now activated for most laptops as well as Macintosh desk machines. One can view large files in greater detail, and switch easily to Small symbols if necessary. Finally, the new Plotnik09.1.1 has the capacity to play individual tokens from a single time-stamped .wav file prepared by Praat. Note: The latest update provided here, 09.1.3, is an update that adds the capacity to compare the separation of allophones using the T-test function. Download Plotnik09 (version 9.1.3).

  Plotnik 09 features:

            Open vowel:  instead of opening a whole vowel system, open and immediately display only the vowels hilited in the Vowel List.
            Add file...   combine files by adding a new file to the current file.
            Scatter vowels:  when vowels overlap, they may be made visible by scattering at minimal distances around the original target.
           Type window:  classify vowel systems and save records according to your own typology.
           Hilite series:  specify a list of environments to be successively hilited and labeled with a single key stroke.
           Hiliting by color:  hilite vowels by complementary color in addition to black outline.
           New function keys:  hilite or hide vowels before nasals, liquids, voiceless segments, and pause.
