Speech Science Research Overview
Veatch's research has
investigated the physical, mental, and social aspects of the sound
system of human language. His dissertation, directed by Mark Liberman
and William Labov, explores aspects of the phonetic implementation
system, including a theory of the acoustic phonetics of vowels, a
treatment of the post-lexical phonological structure of a reference
American dialect of English, and a number of phonological and
acoustic-phonetic investigations of the mapping from sound structure
to measurable acoustic form in language production. His large-scale
acoustical studies are innovative in a number of ways. Rather than
studying elicited reading passages or other relatively artificial
forms of speech, the data is natural conversation. Several dialects
are studied: Jamaica, Los Angeles Chicano, Chicago, and Alabama. The
vowel systems in natural speech are characterized acoustically and
compared across dialects. Exhaustive analysis of a conversation,
measuring thousands of vowels per speaker, enables the effects of
stress and of consonant context on vowel pronunciation to be
quantitatively characterized. Differences in phonetic processes are
used to establish the existence of a phonetic component of linguistic
structure; a number of processes or patterns characteristic of this
level of grammar are explored.
Veatch's pre-dissertation research investigated perception of speech
across dialects using both natural (gated) and
modified-and-resynthesized speech forms in perception experiments. He
also explored the patterns of a very common yet largely unknown
phonetic process of English, word-final fricative devoicing. He
studied the differences in speech production between native and
non-native speakers in a newly-creolizing pidgin in New Guinea, and he
carried out experiments on the perception of rapid speech sounds. He
has also worked on applying the techniques of automatic speech
recognition to problems in speech research.
Veatch's post-thesis research has followed up on his thesis work on
the structure of the English vowel system, and on the theory of vowel
acoustics. He has added evidence supporting the hypothesis of
on-going historical linguistic divergence between African-American and
white dialects in the U.S. through a study of the low-back vowel
merger in California. He has done preliminary work on the development
of a grammar or model of acoustic-phonetic durational patterning, and
on applying these modelling techniques to questions of dialectal and
stylistic variation. He has studied the phonetics, phonology, and
sociolinguistics of the on-going historical change of a consonant,
/l/, to a vowel sound, in various dialects including that of the
African-American English Vernacular and that of Utah.
In an unrelated line of research, Veatch developed a theory of the
psychological phenomenon of humor, which was well-recieved at a recent
conference on humor and the write-up for which has been accepted for
publication by Humor, the Journal of the International Society of
Humor Research, from Mouton.
