Are the communications of African flight attendants a form of slurred speech?

Onboard international flights, you may have witnessed the pre-takeoff information/in-flight safety speech by the cabin crew. It is not out of place that they tend to be European in their mode of speaking. However, when on a local flight, the Europeanness of speech still comes out loud. We want to understand why such Europeanised intonation should be and the audience it is meant to serve. Our  research leads us to the conclusion that this insensitivity of local airline operators stems from the desire to enjoy some patronage even if their actions inferiorise the community who are the major patronisers of their services. We will also explain why the Europeanisation of speech could lead to safety hazards. This work is inspired by the personal experiences of the researchers and of a few others.
