[Freeswitch-users] How to specify language for phrase macro inside session:playAndGetDigits(-)

Hi all, { session:playAndGetDigits(1, 1, 1, 3000, "#", "phrase:xk_confirm_userid:" .. uid, invalid, "[0,1,9]") } always uses default language (e.g. 'en') to pick up phrase marco definition, but now I would like to specify another language instead of FS default language to play back this phrase macro inside session:playAndGetDigits(-). Could anyone please tell me how I can specify non-default language for playing back my phrase macro inside session:playAndGetDigits(-)? Thanks x.k.
