The phonetic forms of DAR are very varied. The "th'" form suggests a
voiceless dental fricative realisation, usually voiceless (as in
thin), and is restricted to the western parts of the DAR area (
Lancashire and
Cheshire). It also occurred widely across northern and central
Staffordshire in earlier dialect surveys (Jones 2002). Sporadic forms similar to DAR were reported to occur in localities in
Berkshire,
Sussex and
Essex and also in
Aylesham, in
Kent, because of the large influx of miners from
Northern England to work in the Kent Coalfield. The "t" form suggests a
voiceless alveolar plosive or a
voiceless dental plosive realisation , as in
tin, but also serves to represent a '
glottal' form. The glottal form is most widely encountered and is typical of the Yorkshire dialect. In southern
County Durham, the definite article is traditionally reduced to , as in Cumbrian, but may also be voiced to . Some dialects may show more than one phonetic form, but the conditioning factors for such variation are unknown. It seems that unvarying glottal forms are most widely found now (2005). Variation with a full form
the is also common. Speakers of other forms of English often find it difficult to hear, especially the 'glottal' forms that affect the pitch and duration and voice quality of surrounding words and sounds in subtle ways. This often leads to claims that the article is absent, but this is rarely the case. True absence of the article may occur in the east of the DAR area, in and around
Kingston upon Hull. Instrumental acoustic work in 2007 showed that DAR speakers use very subtle differences in the quality and timing of
glottalisation to differentiate between a
glottal stop occurring as an
allophone of final /t/ in a word like "seat" and a
glottal stop occurring as the form of the definite article in otherwise identical sentences (compare "seat sacks" and "see t' sacks"). Speakers of DAR dialects therefore appear to have (put somewhat simplistically) two kinds of glottal stop: one for DAR and one for word-final /t/. ==See also==
