This article focuses on the variety spoken in the Dutch town of Kerkrade.
In contrast to Limburgish and Standard Dutch, but like other varieties of Ripuarian, the Kerkrade dialect was partially affected by the High German consonant shift.
For instance, the former /t/ became an affricate /ts/ in word-initial and word-final positions, after historical /l/ and /r/ as well as when doubled.
[1] As most other Ripuarian and Limburgish dialects, the Kerkrade dialect features a distinction between the thrusting tone (Dutch: stoottoon, German: Schärfung or Stoßton), which has a shortening effect on the syllable (not shown in transcriptions in this article) and the slurring tone (Dutch: sleeptoon, German: Schleifton).
This is nothing more than a convention, as the phonetics of the Kerkrade pitch accent are severely under-researched.
