Dear Toritoribe-san
Thanks a lot firstly!
失礼ですが, Are there any other high vowels?
And you've mentioned that close vowels are often devoiced at the end of a sentence. So, can I pronounce "よろしく" as "yo-ro-sh-k"?
Is it strange if I don't follow the rules in Kanto era?
Besides those between "k" and "s" or "k" and "sh" have to be kept silent, how about those between " g, b, t, h, m, y, n, r,.........."?
At the end, I should say どうもありがとうございました or どうもありがとうございまし?
