WVDP Reports
From August to January…
From August 2012 to January 2013,
the West Virginia Dialect Project (WVDP) spent hundreds of hours submerged in
Phase Two of their three-phase NSF plan. Phase Two consists of a study of
phonetic variation in Appalachia.
Phonetic variation in any region is
a daily event. Language is constantly changing to cope with social, geographic,
and linguistic pressures. The WVDP is researching the changes in language that
have occurred throughout the years, specifically in Appalachia. To get a better
social viewpoint on this change, the WVDP is carefully investigating 67 speakers
in the West Virginia Corpus of English in Appalachia (WVCEA). These speakers are
evenly distributed by age, gender, and geographic location.
During Phase One of the WVDP, each
speaker in the WVCEA participated in an interview. The WVDP team then manually time-aligned each audio
file with its transcript, so that the written words flow along with the sounds.
Each time-aligned interview is divided
into thousands of utterances; these sound slides can then be analyzed with
computer software to assess their acoustic qualities. The time-aligned files
are stored on the Sociolinguistic Archive and Analysis Project (SLAAP) database
at the NC State Library.
The first step of Phase Two was to search
and organize these sound slides from the SLAAP database. The database can be
searched based on the orthographic spelling of words spoken within the audio
file. Specifically, the team worked with files containing [h]-initial words and
[w]-initial words.
What we’re working on
now….
Once the proper audio files were identified,
the WVDP then began the process of acoustic analysis. Using a acoustic analysis
software called Praat, the WVDP primarily focused on the study of two different
variations: h-lenition and w/wh-merger.
H-lenition
is a change of the [h] sound in words like huge
and Houston. The [h] was occasionally
lost in such words; instead of having a strong, breathy sound, the words might
start with the sound. The loss of [h] might also be happening in
words like hope and head.
The w/wh-merger is a change where the historically voiceless
sound of which is becoming more
voiced like the sound of witch. Historically,
- and -initial words have had different pronunciations. The
[w]-initial sounds in and are examples of how these
two sounds are merging. The WVDP is in
the process of analyzing this merger and how this variation has changed over
time. Below, the picture shows the w-merger
analysis process for one particular speaker in the WVCEA.
