Comparing Prepared Speech with Spontaneous Speech
Unless the speaker is not fluent in English (second or higher language), in prepared speech there is an absence of non-fluency features like hedges, fillers, micro-pauses.
"um like this is probably like (.) like (0.5) no:::t a good example of (.) ah (.) yeah(.) prepared speech."
Literary features like metaphors and the rule of three should also be more common. Weasel words like "Virtually" and "Probably" are also very common in political speeches because they are vague enough to be able to support an opinion without giving proof for example
"Demisexual Genderfluid Transethnic Trees are probably having an identity crisis"
Most really important speeches are in received pronunciation which is like BBC English and it is generally agreed to be the sociolect of those in power politically. Since Text A is likely to be a conversation between two people with a wierd sociolect you can use this as a comparison point.
