Note This is a version of the AI course policy I’m introducing this semester. 🚫 When in doubt: No. There is no aspect of this course for which it is recommended, appropriate, or acceptable to turn to a Large Language Model (more commonly called an AI) such as ChatGPT. This includes: Working on graded assignments, quizzes, or discussion prompts. As a supplement to the readings or course notes.

I just saw a really interesting paper by Scott Nelson and Jeffrey Heinz (Nelson and Heinz 2025) that proposes a model of phonology and phonetics as complex function application that maintains a discrete phonology while also alowing for things like incomplete neutralization. I myself am always sort of able to follow formal notation, but get a better understanding if I try rewriting it in a programming language of some sort.

I’m not sure when I first came across his stuff, but I’ve really admired Andrew Heiss’ public scholarship, including his blog, which is full of handy stuff. At some point I noticed he had post-level DOIs minted. I knew you could mint repository-level DOIs with GitHub and Zenodo, but maintaining each post as a repository and adding them as submodules to a blog is… a lot.

I had a lot of fun working with the XKCD color survey data, and I think I’ll keep messing around with it here and there in the future. But I also think I’ll want access to the full data. The tidytuesday data set was necessarily boiled down. The answers data frame contained just one hex code associated with one color label, not every color label given to every hex code in the survey.

So now I can finally get to visualizing the effect of “light” and other modifiers on colors! When I eventually get to the plotly code, there’s nothing tidy going on, so I’ll be code-folding most of this stuff.

This tidytuesday dataset of colors labels is like the perfect confluence of interests for me! I’ve started learning how to do digital art to illustrate characters for a D&D campaign: Which means I’ve been looking a lot at a color picker that uses Hue, Saturation and Lightness sliders (even though they’re not labelled that way). But I’ve had an interest in colors and color theory for a while.

When I saw that the TidyTuesday dataset was the the XKCD color survey this week, I had to jump in! source(here::here("_defaults.R")) library(tidyverse) library(tidytuesdayR) library(tinytable) library(mgcv) library(marginaleffects) library(ggdist) library(ggdensity) library(geomtextpath) set.seed(2025-07-08) # eval: false # downloading &

Yesterday I posted about the normalization functions in the tidynorm R package. In order to implement formant track normalization, I had to also put together code for working with the Discrete Cosine Transform (DCT), which in and of itself can be handy to work with.

The upshot The tidynorm package has convenience functions for normalizing Point measurements norm_barkz() norm_deltaF() norm_lobanov() norm_nearey() norm_wattfab() Formant Tracks norm_track_barkz() norm_track_deltaF() norm_track_lobanov() norm_track_nearey() norm_track_wattfab() DCT coefficients norm_dct_barkz() norm_dct_deltaF() norm_dct_lobanov() norm_dct_nearey() norm_dct_wattfab() As well as generic functions to implement your

By default in a quarto document, the code and output look something like this: set.seed(2025) rnorm(10) [1] 0.62075674 0.03564140 0.77315448 1.27248909 0.37097543 -0.16285434 [7] 0.39711189 -0.07998932 -0.34496518 0.70215136 Maybe this is just me not wanting my peas to touch my mashed potatos, but I don’t like how close the output is to the text of the document.

Weinreich, Labov, and Herzog (1968) is a foundational text in my subfield of linguistics. Entitled “Empirical foundations for a theory of language change,” it’s both a comprehensive review of the field at the time, and a programmatic outlook for the future, laying down problems that researchers are still grappling with today.
