Obtaining Linguistic Data
Many procedures are available for obtaining data about a language. They
range from a carefully planned, intensive field investigation in a foreign
country to a casual introspection about one's mother tongue carried out in an
armchair at home.
In all cases, someone has to act as a source of language data — an
informant. Informants are (ideally) native speakers of a language, who provide
utterances for analysis and other kinds of information about the language (e.g.
translations, comments about correctness, or judgments on usage). Often, when
studying their mother tongue, linguists act as their own informants, judging the
ambiguity, acceptability, or other properties of utterances against their own
intuitions. The convenience of this approach makes it widely used, and it is
considered the norm in the generative approach to linguistics. But a linguist’s
personal judgments are often uncertain, or disagree with the judgments of other
linguists, at which point recourse is needed to more objective methods of
enquiry, using non-linguists as informants. The latter procedure is unavoidable
when working on foreign languages, or child speech.
Many factors must be considered when selecting informants — whether one
is working with single speakers (a common situation when languages have not
been described before), two people interacting, small groups or large-scale
samples. Age, sex, social background and other aspects of identity are
important, as these factors are known to influence the kind of language used.
The topic of conversation and the characteristics of the social setting (e.g.
the level of formality) are also highly relevant, as are the personal qualities
of the informants (e.g. their fluency and consistency). For larger studies,
scrupulous attention has been paid to the sampling theory employed, and in all
cases, decisions have to be made about the best investigative techniques to
Today, researchers often tape-record informants. This enables the
linguist’s claims about the language to be checked, and provides a way of making
those claims more accurate (‘difficult’pieces of speech can be listened to
repeatedly). But obtaining naturalistic, good-quality data is never easy. People
talk abnormally when they know they are being recorded, and sound quality can be
poor. A variety of tape-recording procedures have thus been devised to minimize
the ‘observer’s paradox’ (how to observe the way people behave when they are not
being observed). Some recordings are made without the speakers being aware of
the fact — a procedure that obtains very natural data, though ethical objections
must be anticipated. Alternatively, attempts can be made to make the speaker
forget about the recording, such as keeping the tape recorder out of sight, or
using radio microphones. A useful technique is to introduce a topic that quickly
involves the speaker, and stimulates a natural language style (e.g. asking older
informants about how times have changed in their locality).
An audio tape recording does not solve all the linguist’s problems,
however. Speech is often unclear and ambiguous. Where possible, therefore, the
recording has to be supplemented by the observer’s written comments on the
non-verbal behavior of the participants, and about the context in general. A
facial expression, for example, can dramatically alter the meaning of what
is-said. Video recordings avoid these problems to a large extent, but even they
have limitations (the camera cannot be everywhere), and transcriptions always
benefit from any additional commentary provided by an observer.
F Linguists also make great use of structured sessions, in which they
their informants for utterances that describe certain actions, objects or
behavior. With a bilingual informant, or through use of an interpreter, it is
possible to use translation techniques (‘How do you say table in your
language?’). A large number of points can be covered in a short time, using
interview worksheets and questionnaires. Often, the researcher wishes to obtain
information about just a single variable, in which case a restricted set of
questions may be used: a particular feature of pronunciation, for example, can
be elicited by asking the informant to say a restricted set of words. There are
also several direct methods of elicitation, such as asking informants to fill in
the blanks in a substitution frame (e.g. I ___ see a car), or feeding them the
wrong stimulus for correction (‘Is it possible to say I no can see?’).
G A representative sample of language, compiled for the purpose of linguistic
is known as a corpus. A corpus enables the linguist to make unbiased
statements about frequency of usage, and it provides accessible data for the use
of different researchers. Its range and size are variable. Some corpora attempt
to cover the language as a whole, taking extracts from many kinds of text;
others are extremely selective, providing a collection of material that deals
only with a particular linguistic feature. The size of the corpus depends on
practical factors, such as the time available to collect, process and store the
data: it can take up to several hours to provide an accurate transcription of a
few minutes of speech. Sometimes a small sample of data will be enough to decide
a linguistic hypothesis; by contrast, corpora in major research projects can
total millions of words. An important principle is that all corpora, whatever
their size, are inevitably limited in their coverage, and always need to be
supplemented by data derived from the intuitions of native speakers of the
language, through either introspection or experimentation.
