"Martin", the second syllable 'tin', in British or Austrian pronounce like a solid 'ten'
While as in the America or Canada, the 'tin' sounds more like a 'en', i.e. 嗯, but if you pronounced a solid 嗯, you are quite wrong , there is a short leading sound before 'n'. ~n.
Took me quite some practice to properly speak out the leading, maybe a fraction of a full beat. 一种声断气不断的音. 不能读过头, 还要让人清晰的听出来.
Similarly, Britain, Button, in contrast to : 'Boston' where it is a solid: ten/ton/tn..
Wish I made myself clear... ...,
Martin, pronounciation from Youtube:, how do you feel?
