2. Select two normalization methods:

For information about each method, visit the Methods page. Not all methods are equally appropriate for all vowel datasets. Note that, even though the primary proponent(s) for each method are listed, that a number of the methods are slightly modified from their original, published versions. Explications of these modifications are also described on the Methods page.

3. Select options:

Plot all speakers on the same plot? Uses color to differentiate speakers; otherwise generates mean plots in black & white and individual values plots in color to differentiate vowels.

Generate smaller in-line plots? Makes slightly smaller plot JPEGs for viewing with smaller monitors.

Scale normalized results to Hz? Important!: make sure that you have read the About Scaling section.
Only for Lobanov, Nearey, and Watt & Fabricius methods which otherwise result in non-Hz or non-Barks values.
