[Corpora-List] Speech register samples

[L Carmichael]

Greetings,

I would like to find speech corpora of different registers of speech,
e.g., speech that is used in a particular situation, such as that
of an elementary school teacher ("teacher talk"), or speech from doctors
to patients ("doctor talk"), speech directed at non-native speakers,
lectures, casual speech within social groups, etc. ANY amount will be of
help to me.

I'll post a summary. Thank you in advance for your help! This kind of
material appears to be quite elusive.
