Having read a few examples, I can hear the intruding /w/ in do w it, the /r/ in the area r is, and the /j/ in I j agree. In these examples, the intruding sound arises between vowel sounds. I imagine this is always the case. A pupil has asked me about this phenomenon, and though I've found plenty of examples, I can't find any rules regarding in which cases one or other intruding sound appears. Can anyone help? Many thanks for reading this.
