The following online article has been derived mechanically from an MS produced on the way towards conventional print publication. Many details are likely to deviate from the print version; figures and footnotes may even be missing altogether, and where negotiation with journal editors has led to improvements in the published wording, these will not be reflected in this online version. Shortage of time makes it impossible for me to offer a more careful rendering. I hope that placing this imperfect version online may be useful to some readers, but they should note that the print version is definitive. I shall not let myself be held to the precise wording of an online version, where this differs from the print version. Published in Times Higher Education Supplement, 11 Apr 1997. |

THE HANDBOOK OF PHONETIC SCIENCES
EDITED BY WILLIAM J. HARDCASTLE AND JOHN LAVER
Blackwell, vii + 904 pp., £85.00
ISBN 0-631-18848-7
Published December 1996
The declared aim of this book is to be “an advanced
tutorial introduction for students with a basic grounding in phonetics who are
interested in acquiring a foundation for … research in the phonetic
sciences”.
The obvious comparison is with the 1968 Manual of
Phonetics
edited by Bertil Malmberg. The
present book is much longer, reflecting growth in speech science over three
decades. New techniques for
probing articulation and processing acoustic signals have been developed,
computers have been harnessed to the task of decoding airwaves into words, and
the advent of “human-centred
information technology” has expanded the practical applications of the
discipline.
This Handbook offers an excellent way of catching
up with these advances. Its list
of contributors could hardly be more distinguished. Most chapters offer admirably clear and up-to-date surveys
of their topics; the first chapter, by Maureen Stone on laboratory techniques
for investigating articulation, took me in 22 pages from initial ignorance to a
satisfying grasp of the fundamentals of techniques such as computed tomography
and magnetic resonance imaging.
Its quality is typical of the chapters that follow (though some of them make
larger assumptions than others about the reader’s prior knowledge of relevant
aspects of mathematics or physics).
The Handbook does not render the earlier Manual entirely obsolete. I tested it on an issue that cropped up
in my teaching recently, about formant-frequency differences between the sexes. A chapter by Gunnar Fant in the Manual included two or three
pages on this topic. The Handbook index led me only to a
bare mention of the existence of such differences, in Francis Nolan’s chapter
on speaker recognition and forensic phonetics; and I found a more explicit,
unindexed statement in Kenneth Stevens’s chapter,
“Articulatory-acoustic-auditory relationships”, but this said far less than
Fant said in 1968. The main Handbook
chapter on
acoustic phonetics, by Osamu Fujimura and Donna Erickson, seems less successful
than many other contributions, reading as if it was put together in a hurry –
unfortunate, in view of the central importance of this topic. Most contributors are conscientious
about surveying the main features of their assigned field in an even-handed
fashion, but quite a lot of Fujimura and Erickson’s chapter deals with
Fujimura’s idiosyncratic analysis of English phonology, which makes English
look more like Japanese than it normally does, and seems out of place here.
Although editors and publisher are British, the “centre
of gravity” of the Handbook is American – a fact which reflects shifts in the
subject itself. More than half of
the 26 chapters are contributed by authors working in the USA. A generation or so ago, phonetics was a
subject in which Britain played a leading – perhaps the leading – role, and
British phonetics had a distinctive agenda emphasizing detailed observation of
the sounds found in all varieties of human speech, including exotic languages
and non-standard dialects. That
agenda is largely absent from this book.
Most chapters assume a world in which people speak standard varieties of
American English or a handful of other well-known languages. The few exceptional chapters are mostly
by cisatlantic authors (e.g. the chapter on voice quality by Ailbhe Ní Chasaide
and Christer Gobl of Dublin), or by authors such as Peter Ladefoged who work in
the USA but are British by training.
(A 1996 book by Ladefoged and Ian Maddieson, The Sounds of the
World’s Languages,
complements the Handbook
in this respect.)
This emphasis on familiar languages is partly a
consequence of the increased technical sophistication of instrumental and
computational phonetics, which inevitably draws mainly on languages spoken in
the vicinity of expensive laboratories; it is reinforced by the modern pressure
on academics to make their research responsive to the needs of the taxpayers
who fund it, which is only fair.
Nevertheless, from a humanistic point of view this retreat from
engagement with the full diversity of human speech sems regrettable. Much of the liberal educational value
of language studies used to lie in the way that they revealed astonishingly
subtle and diverse organization in the speech even of obscure tribes.
Peter Ladefoged’s chapter on “Linguistic phonetic
descriptions” is an exception to another trend in this volume. Most contributors give no credence to
the once-fashionable idea that speech sound encodes a system comprising a few neat
patterns embedded in the brains of our species as part of an inherited
“language organ”. Bertrand
Delgutte’s chapter on the auditory neural processing of speech lists numerous animal
species which have been found to hear speech sounds in much the same way as us. Ladefoged (whose stature within the
discipline is justly reflected by his being the only author allotted two
chapters) takes a line which has always seemed oddly schizophrenic. On one hand, Ladefoged more than
perhaps anyone else draws attention to the fact that sounds unlike any in familiar
languages sometimes occur with clearly phonemic status in one obscure language. Pirahã, spoken by about a hundred
people in Brazil, has a double flap sound which involves protruding the tongue
so that it almost touches the chin.
On the other hand, Ladefoged continues to pursue a programme, introduced
in his 1971 book Preliminaries to Linguistic Phonetics, of finding a system of
binary or few-valued features adequate for describing the sound patterns of all
languages.
If speech sounds were all definable in terms of a few distinctive
features, how could the Pirahã oddity fit in? Some linguists have argued that diverse sounds are shown to
be related abstractly by behaving phonologically as “natural classes”, but
Ladefoged rarely discusses data of that sort; John Ohala, in a Handbook chapter which queries the
validity of phonology as an independent subject, concludes that natural classes
of sounds may play no role in speakers’ grammars. Ladefoged merely says that although strange sounds do not
fit the theory, if they are rare enough that does not matter. “Any addition complicates the
theory. It is just a matter of the
price. We always have to decide
whether the extra coverage is worth the cost.”
Surely this takes a Thatcherite approach to science
beyond reason? The virtue proper
to a scientific theory is to be true, not to be cheap. It is one thing to advocate a theory
despite a few awkward phenomena that one has not yet managed to reconcile with
it; it is another to claim that a theory is true even though it is contradicted
by evidence that one has no intention of reconciling. Ladefoged’s distinctive-feature programme harmonizes with
ideas that exerted a powerful hegemony in America for many years, but (on the
evidence of this book) the rest of the speech science community has now
definitively junked them.
The production of the Handbook is attractive, though the
editing could be better. The index
is dire: again and again, for
instance, it omits mentions of personal names, defeating one of the easiest
ways for readers to locate elusive passages. There are few misprints, but I found several wrong phonetic
symbols.
In the context of an achievement as large as this
publication, however, my criticisms are little more than quibbles. This is an important book, which does much
to make accessible the current state of knowledge in an increasingly signficant
discipline.
