joeysvowels package provides a handful of datasets, some subsets of others, that contain formant measurements and other information about the vowels in my own speech. The purpose of the package is to make vowel data easily accessible for demonstrating code snippets when demonstrating working with sociophonetic data.
There are no functions contained in
joeysvowels; it’s a data-only package.
You can install
joeysvowels through GitHub:
You can then load the package like noromally:
Currently, there are five datasets contained in
darla is one that was prepared using pretty standard methods, using the DARLA web interface to automatically transcribe, force-align, and extract formants from the audio. The audio was me reading 300 prepared sentences. It’s a bit of a noisy dataset, so it’s a good example of working with real data. It is also very close to the format that FAVE exports its data, so any examples that use
darla can be easily modified to another FAVE-produced spreadsheet.
coronals is a much cleaner, more controlled dataset. You can read about the methods by viewing the documentation (
?coronals). Essentially, I read a bunch of (C)CVC(C) nonce words where the consonants were (almost) all coronal. All my vowel phonemes are represented. I aligned and extracted formants from the data myself. Four formants were extracted every 5% of the vowels’ durations, so great for demonstrating functions and visuals involving vowel trajectories.
midpoints is a subset of
coronals and contains only the midpoints from F1 and F2.
mouth is a subset of
coronals and is only the MOUTH (/aw/) vowel.
mouth_lite is a subset of
mouth and trims away most of the columns and only contains 10 tokens.
You can access the datasets using
data(). I’ll briefly visualize the datasets.
darla dataset is messy.
data(darla) ggplot(darla, aes(F2, F1, color = vowel)) + geom_point() + scale_x_reverse() + scale_y_reverse()
coronals trajectories show clear influence from the surrounding consonants.
## `summarise()` regrouping output by 'vowel' (override with `.groups` argument) ## # A tibble: 273 x 4 ## # Groups: vowel  ## vowel percent F1 F2 ## <fct> <dbl> <dbl> <dbl> ## 1 LOT 0 454. 1616. ## 2 LOT 5 592. 1346. ## 3 LOT 10 648. 1283. ## 4 LOT 15 651. 1238. ## 5 LOT 20 661. 1178. ## 6 LOT 25 651. 1176. ## 7 LOT 30 636. 1152. ## 8 LOT 35 630. 1148. ## 9 LOT 40 633. 1153. ## 10 LOT 45 625. 1158. ## # … with 263 more rows
ggplot(avg_trajs, aes(F2, F1, color = vowel)) + geom_path(aes(group = vowel), arrow = arrow(angle = 20, length = unit(0.15, "in"), type = "closed")) + scale_x_reverse() + scale_y_reverse()
midpoints is pretty clean.
data(midpoints) ggplot(midpoints, aes(F2, F1, color = vowel)) + geom_point() + scale_x_reverse() + scale_y_reverse()
mouth shows pretty good trajectories.
mouth_lite is just smaller.
