In rapid, everyday, connected speech, English speakers tend to simplify long/complex consonant clusters. This feature, called Elision or Dissimilation, may occur in a few different contexts, and Ed Sheeran illustrates one of them very clearly: when two words meet creating a 3-consonant cluster or when there is a non-initial 3-consonant cluster within a word, the consonant in the middle of the cluster might not be pronounced. This is why you might find the renditions in brackets of the phrases/words below in connected speech:
'next day' [nɛks dej]
'reached Paris' [riːtʃ pærɪs]
'blind man' [blajn mən]
'postman' [pows mən]
Now watch the video and check out the word in which a consonant is clearly not pronounced:
Yes, it's the word 'sixth', rendered by Ed Sheeran as [sɪkθ].
Stay tuned for more videos, and if you have a suggestion of a video clip I could use to illustrate a feature of English or Portuguese phonetics, please send it to me.
