Gazetteer of Southern Vowels
This site was created to allow you to interact with data extracted from the Digital Archive of Southern Speech. The site is still in beta mode and is undergoing active development. Please report and bugs, suggestions, or comments to Joey Stanley at email@example.com.
Where do the data come from?
The Digital Archive of the Southern Speech (DASS) is an audio corpus of semi-spontaneous linguistic atlas interviews (Kretzschmar
2012) derived from the Linguistic Atlas of the Gulf States (Pederson
1986). It contains speech from 64 natives (34 men and 30 women, born 1886–1965) of 8 Southern US states. This sample contains a mixture of ethnicities, social classes, education levels, and ages.
DASS is currently undergoing transcription, forced alignment, and acoustic analysis (see Renwick
The corpus can be licensed from the
Linguistic Data Consortium,
Linguistic Atlas Project hosts it
via mp3s, speaker biographies, and more.
What does this site do?
Currently, the site has four main pages:
Vowel Plot Comparison:
On this page, you can subset the DASS data by many demographic attributes and view the corresponding speakers' vowel tokens plotted in F1, F2 space. You can also subset by vowel and following consonant and choose what normalization technique (if any) and transcription system should be used. The plots are extremely customizable and users can change how the data is displayed. Two graphs are included on this page to—given a large enough screen size—facilitate side-by-side comparison of subgroups. Below each graph are tables that give basic summaries of the speakers and the vowels selected.
Interactive Vowel Plot:
Here you can focus on specific portions of individual speakers' vowel space and see words rather than just points. If you click on the plot itself, a table at the top will display the five points nearest to where you clicked, showing you exact formant measurements.
Point Pattern Analysis:
This is an alternative way of viewing the vowel space, pioneered by Kretzschmar. On this page, you can again subset the data by demographic characteristics and by vowel and see a scatterplot in F1, F2 space. The underlaid grid indicates how many observations lie in each cell, with the number of rows and columns in the grid controllable by the user. Below the plot is a chart of the distribution of the grids, plotted in decreasing order of density. The resulting chart follows an Asymptotic Curve (or simply, "A-Curve").
The maps page allows users to explore the distribution of speakers in DASS, with some flexibility on how various demographic categories are displayed.
New content is being added regularly, so check back soon for additional features.
How is this site powered?
This site is built in
a web application framework for R. With Shiny, users can utilize the computational power of the R programming language without having to learn R or install it to their computers. This is all bundled up and put on the web to allow for the interactive capabilities of web browsers.
How is this project funded?
This research is supported by:
NSF BCS #1625680
to co-PIs Kretzschmar and Renwick, the
University of Georgia Graduate School,
American Dialect Society.
Who is involved?
The PIs for this project are William Kretzschmar and
Margaret E. L. Renwick,
of the University of Georgia. Our team has several student researchers including Mike Olsen, Rachel Olsen, and
We also have several dozen undergraduate student workers, funded by ADS or NSF, that do most of the transcribing work.
