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

Normalization & Processing:
Include F3 in Processing:
No Yes Only relevant for Nearey and Labov methods. Bark difference requires F3 values. Lobanov and Watt & Fabricius are not implemented to use F3. Note that including F3 for Nearey and Labov methods changes the results for values of F1 and F2; it is not just a matter of whether or not you want F3 values normalized.
No Yes Only relevant for Lobanov, Nearey and Watt & Fabricius methods, which otherwise result in non-Hz or non-Barks values. Important: We do not recommend scaling. Make sure that you have read the About Scaling section.
