Clicking
If you were to transcribe a Bambara conversation in Mali, it might look like this (translated into English)-

Zumana: How are you today Passani?
Passani: I am fine!
Zumana: And your family?
Passani: They are fine
!also.
Zumana: What did you work on today?
Passani: I worked on my translation today from Bambara! to English.
Zumana: That's great. Did you have any problems?
Passani: !! I certainly did. !I could not !get one of the sentences just the way I wanted it!!

The exclamation marks are not some indications of premature excitement, but rather a linguistic notation for 'clicking' sounds. Clicking sounds are routinely inserted into everyday conversations amongst Maliens.   They are generally a form of agreement.  Clicking has been associated with selected African languages since ancient times. Clicks embedded in conversation are actively used today in Mali.  Here is a recording of a short conversation which includes
'clicks'.
