Ulster English and Dublin English
The dialects of the northern province, Ulster (Harris 1984, McCafferty 2007), are quite different from those in the south. The main reason for this is that they derive from Lowland Scots and forms of northern English which were taken to Ulster during the plantations of the seventeenth century. These varieties led to forms of English in the north which are easily recognisable to this date. However, the English of the two main ethnic groups in the north, Protestants and Catholics, are not usually distinguishable by their English (but see McCafferty 2001 for some differences with regard to innovation and conservatism in the respective communities).
Ulster English and Dublin English
The most distinctive form of Ulster English is Ulster Scots which, in its historically continuous, traditional form, is a rural variety spoken along the coast of Northern Ireland and derives from Scots settlers who came from Scotland to Ulster in the 17th century (see relevant sections of Bardon 1996). It is a paradox of English in present-day Ireland that there are three phonological parallels between Ulster Scots and present-day advanced Dublin English: (i) short front vowel lowering, (ii) a retroflex [ɽ] in syllable codas and (iii) intervocalic t-flapping.
Lowering of KIT vowel (traditional Ulster Scots speaker)
Lowering of TRAP vowel (traditional Ulster Scots speaker)
Retroflex syllable-coda [ɽ] (traditional Ulster Scots speaker)
Intervocalic T-flapping (traditional Ulster Scots speaker)
However, this is where the parallels stop. There are other central features of Ulster Scots which have no equivalent in any kind of Dublin English: (i) AI-tensing, (ii) Lack of phonemic vowel length (both linked to the Ulster manifestation of the Scottish Vowel Length Rule, Aitken 1981), (iii) DH-intervocalic deletion, (iv) Palatal glides after velars and (v) FACE-breaking.

Palatal glide after velar stop (traditional Ulster Scots speaker)
Breaking of FACE vowel (traditional Ulster Scots speaker)
FACE-breaking is very widespread in Ulster and characteristic of speakers from south of the border. Pronunciations like save [se:əv] are a clear indication in the south of Ireland that a speaker comes from somewhere closer to the border with Northern Ireland, e.g. from Co. Louth, Co. Monaghan, Co. Cavan or Co. Donegal.

Lastly one should mention that the intonational patterns in Ulster English, especially Ulster Scots, are quite different from those in Dublin. In the following sound file one can hear a typical Ulster Scots speaker uttering a simple sentence. Note the intonational dip on the stressed syllable of ‘bother’ and the rise at the end of the sentence. This final rise is incidentally much older than the high rising terminal which spread through the anglophone world in recent decades and is unrelated to it. Both the dip (arrow 1) and the rise (arrow 2) can be clearly recognised in the spectrogram of the sentence.

Ulster speech has been treated in many publications, some of these book-length, such as Adams (ed., 1964), an early collection of articles or Mallory (ed., 1999), a more recent volume. In Ulster, the status of Ulster Scots is a topic of considerable controversy, not only among linguists (see the discussion in Hickey 2007: section 3.3). Treatments of it as a separate language are Fenton (2006), a lexical study, and Robinson (1997), largely a treatment of grammar.
