On YouTube you can find speeches in Chinese by former Australian prime minister Kevin Rudd (Chinese name 陆克文), such as this and this and this. Now I'm tossing up whether or not this (or some similar official speech by a L2 Chinese speaker) would be beneficial to study to improve my Chinese. Thoughts:
I don't know who wrote these speeches; it could have been a native Chinese speaker, or it could have been Kevin Rudd himself.
I'm tempted to think that some of the structures used and and word choices made by Kevin Rudd may be particularly suited to an L2 Chinese learner; perhaps they're "just right" for making one's speech sound more fluent.
Studying from L2 Chinese speakers might not be the best (even if they can speak in a professional setting), e.g., it'll almost certainly contain more mistakes than L1 Chinese speakers.
Question: Is studying speeches by e.g. Kevin Rudd especially beneficial for improving one's Chinese speaking skills?
