On Friday, the 13th of February, and on Monday, the 6th of January, I wrote about ejectives. In the meantime I came across another Brit speaker who uses ejectives every now and then: Dr Lucy Worsley1, Chief Curator at Historic Royal Palaces. You can hear Lucy Worsley in various clips on youtube. I chose the video clip in which she introduces her book titled If Walls Could Talk. Listen closely to the word 'talk' as part of the clause "if walls could talk" at about 0:10 or to the word 'work' in the sentence "[b]ut imagine sharing your bedroom, even your bed, with other family members, with your work colleagues, even with strangers" at 1:47. Both k-sounds are produced as ejectives. Listen, please!
BTW: If you listen to her saying "present" (~0:32), "Britain" (~2:47) or "bring" (~3:40), you'll discover that she has slight problems with the r-sound after a bilabial plosive. It reminds me of Woy Jenkins.
1My thanks go to Graham Pointon for drawing my attention to Dr Worsley and her habit of replacing th's by labiodental fricatives.
