I was looking at old Kunqu opera the other day and was interested by the fact that the singers seemed to be pronouncing 也 as "yi" instead of "ye", for example in http://www.tudou.com/programs/view/sAj9FgdRmK8:
好天气也 (00:12) 好困人也 (14:50)
Both instances sound like yi, not "ye3" as in Mandarin (it also struck me as such in a different recording, which I can't find online right now). Since the pronunciation in Kunqu is supposed to be based on an old form of Suzhou dialect, I'm curious whether 也 can still be pronounced like "yi" in more modern forms of that dialect, and if so - does Suzhou dialect include some sound like "yi" that happens to be used as a termination particle?
If so, it might be an intriguing case of a supposed signature of Classical Chinese - using 也 to terminate a clause - being present in vernacular Chinese as well. Of course, I might simply not hearing that it's actual "ye3" in the above, in which case apologies.
