Dialect Test
The Dialect Test was created by A.J. Ellis in February 1879, and was used in the fieldwork for his work "On Early English Pronunciation". It stands as one of the earliest methods of identifying vowel sounds and features of speech. The aim was to capture the main vowel sounds of an individual dialect by listening to the reading of a short passage. All the categories of West Saxon words and vowels were included in the test so that comparisons could be made with the historic West Saxon speech as well as with various other dialects.
Frankfurt School
Marx thus extensively relied on a form of dialectical analysis. This method—to know the truth by uncovering the contradictions in presently predominant ideas and, by extension, in the social relations to which they are linked—exposes the underlying struggle between opposing forces. For Marx, it is only by becoming aware of the dialectic (i.e., class consciousness) of such opposing forces, in a struggle for power, that individuals can liberate themselves and change the existing social order.
