Corpus-based methods of research estimate frequency or occurance:

Laboratory experiments are used to establish phonological (cognitive) categories through imitation, discrimination and identification

Field work includes the methods of interview, a survey (opinion polls) through questionnaries and recording the subjects (rundown choice or selective)

Although opinion polls and survey via telephone are quite chip, time-convenient and cover different groups of population, there might appear some difficulties depending on the topic of the speech, the volume of the voice, the speaker may behave unnaturally or can be not eager to communicate; and still there are limits to the duration of such process as telephone survey. Moreover, there may arise some problems with the quality of connection and therefore, speech and data.

Field work in comparison to laboratory experiments is held in the environment which is not artificially controlled. On the one hand, it is supposed that the results are verifiable and natural. On the other, there are limits to extra conditions that the researcher might want to apply and also some unpredictable circumstances may appear on the way.

Statistical methods are used to check if the data on frequency and variability is significant:
