With the Universal Translator always in play in Star Trek it can be misleading as to whether alien characters are actually speaking English, or are speaking in their own language which is been translated for the benefit of Picard/Sisko/whoever and most importantly us the audience.
Say a scene where Picard is talking to some Klingons; we hear them in English, but are they actually speaking it or are they really speaking Klingon but the UT is translating for them, and from their point of view Sisko is speaking Klingonese?
So I wondered for all the main alien crew characters in Trek, which ones speak in their native tongues and which speak English.
ENT-
T'Pol- Noted various times she speaks fluent English
Phlox- I'm assuming the same as above
TOS-
Spock- I imagine some as intelligent as Spock surely learned to speak English
TNG-
Worf- A Klingon, but raised by Human parents I believe Worf would speak English
Troi- Again, one human parent, probably speaks English just as well as Betazoid
DS9-
Kira- I would assume throughout the series Kira was speaking Bajoran from her POV
Quark- Like above, I'd say Quark spoke in Ferengi
Odo- Interesting, perhaps a mix of Cardassian & Bajoran, probably learnt English too
Jadzia/Ezri- Native Trill or would they have learnt English?
VOY-
Tuvok- Like Spock, could easily speak English I presume
Torres- Raised in a more human than Klingon environment so again, English
Neelix- Surely speaking in Talaxian
Kes- As above but with Ocampan
Jadzia & Ezri is a debatable one. Do you think most people who joined Starfleet would try and learn English, or would it not be a big thing? (not that I think it would be a requisite)
