She's Malaysian, and that's the typical station announcer in most, if not all, large Imperial stations.
(ok maybe not Malaysian, but probably is)
Well whether or not Singaporean or Malaysian, no diff... I personally treat Malaysians as locals. 99.999% same culture, mannerisms etc. Just some Chinese words might differ, and some idioms in English that makes sense in Malaysia but not Singapore. Oh and Malaysians mix more Malay words into English sentences, and Singaporeans mix more Chinese into English sentence. Very slight difference, but still understandable to one another. When speaking Chinese, Singaporeans mix more English words into the Chinese sentence, and Malaysians mix Malay words into their Chinese sentences. That's the only big glaring difference to tell them apart.
Well, since you say many stations in the Empire has this voice... I might just switch allegience! Time to start moving my ships from Sol to a new station somewhere in the Empire....(and start grinding ranks too).
