Merc Speech Notes

Scout

Scout tends to pronounce "freakin'" quite clearly, rather than the more common (at least, where I am) "fricken'".
There is a rare competitive voiceline where Scout invokes God using, instead of his usual "jeez", the phrase "Dear God". There is also a rare competitive voiceline (for 6's) where he refers to his bat as "Bashy".
Scout uses "yeah" and "uh" as crutch words.
Scout uses "let's go" as a sort of compound verb - e.g. "Would you just let's go?", although this is only in one voice command, so it's possible this is a result of him accidentally mixing up his speech rather than an actual linguistic quirk.
Scout occasionally drops pronouns where they're implied - e.g. "Need a dispenser here!".
Scout sometimes drops the verb to have in present perfect tense - e.g. "We got a spy" rather than "We have got a spy".
Scout prefers "thanks" over "thank you".

Sometimes will repeat words/ root words/ sentence structures - e.g. "You are all weak. You are all bleeders." or "This is my point and you will help me defend my point." - usually for emphasis.
Uses a lot of non-verbal vocalisations - groans, battlecries, etc.
Tends to chop his speech up into short discrete parts. This may be via short sentences, separating out individual words with full stops of commas, or from dropping conjunctions.

...

Has a potential negative voiceline where he invokes his "mother Tilly".
Tends to be quite grandiose or dramatic when he has the opportunity, but conversely can also be brief when when the situation calls for it, or if he's caught off guard.
Uses "mate" rarely - much prefers "lad" or "lads".

Tends to be brief, but also often makes emotional appeals or descriptive statements.
Often draws out or emphasises certain important or phrase ending words. On occasion, might be rather sing-song.
Fond of onomatopoeic sounds.

Uses "boy" or "son" as perjoratives quite frequently.
Curses surprisingly frequently - "damn" is a common one, but also "son of a bitch" and "hell".
Tends to drop "[x] was a" or similar when it can be viably implied - "nice job" is an obvious example, but also "hell of a shot" and "Spy around here".

Laughs an awful lot.
Peppers his speech with German or falls back on it completely (with varying actual correctness, mind) quite often compared to, say, Spy.
Gets quite barky when frustrated.

Often refers to his teammates colloquially as a whole as "lads" - potentially more so than "mates". "Mate", however, is pretty common.
Uses bloody as an intensifier an awful lot.
Sentence construction can be unusual at time - e.g. "long as" rather than "as long as", "you'll not" rather than "you won't".
Tbh. I think someone messed up when they were looking up the Australianisms because I've never head anyone say "Ripper you little" in my entire life and I'm feeling like someone read "Ripper, you little" on a website somewhere and didn't notice the comma.
Realistically speaking a certain degree of Sniper's speech patterns could overlap with Demo's. They already do to a certain degree but a bit more of stuff like "me" instead of "my" and the like wouldn't be unrealistic.

Spy doesn't really use curse words as sentence intensifiers. What curse words he does use are invocations of God (mon dieu, sacrebleu) or just plain swearing (merde, fuck).
Spy prefers to insult people directly rather than using curse words for it.
Spy has a tendency to extend communication that would generally be short into full phrases/sentences - e.g. "I'm afraid not" or "You have done well".
