## voweldata [phonTools]

Voweldata is a data set (not a function) that provides information about the vowel data sets included in the package. Nine data sets are included in all, comprising vowel formant information from several different languages. I am always looking to add more, so if you have vowel data that you would like to make available let me know!

The plots below show the mean values for the vowel categories in each data set. Duplicate instances of some categories indicate separate male and female mean values.

Code used to generate examples:

```
data(a96); data(b95); data(f99);
data(h95); data(f73); data(p73);
data(pb52); data(t07); data(y96);

## plot all data sets
par (mfrow = c(3,3), mar = c(4,4,4,1))
vowelplot (a96\$f1, a96\$f2, a96\$vowel, logaxes = 'xy', xsampa = TRUE,cex=2,
main = 'Hebrew', xrange = c(200,1100), yrange = c(600,3100))
vowelplot (b95\$f1, b95\$f2, b95\$vowel, logaxes = 'xy', xsampa = TRUE,cex=2,
main = 'Spanish', xrange = c(200,1100), yrange = c(600,3100))
vowelplot (f73\$f1, f73\$f2, f73\$vowel, logaxes = 'xy', xsampa = TRUE,cex=2,
